You'll probably gain in terms of af speed, but you'll have the same problem that you told me I have when we discussed about Sigma 150-600mm lens: the f6.3 aperture on the maximum focal length. :) But, Pentax lens has some nice advantages: it is weather resistant and it is small and light compared to Sigma. :)

I don't try/like to troll or go off topic. What I didn't like in the comments above is that someone implies that I'm lying. How would you react if you say that a list of lenses are "Available on order" because this is what it is written on the Pentax website for the lenses I listed a few comments back and someone starts to tell you that it isn't true because sometimes those lenses apear on stock? :) If you come to Romania as a tourist and you want to buy one of the lenses I listed a few comments back and for each lens it is written "Available on order", do you start thinking of what the store is trying to say when it wrote this phrase? For me "Available on order" means that the store doesn't know when or if will bring these lenses in the shop because of poor sales, but if you want to buy them, place an order.

You perhaps wrote my comments and you realised that I made a few sugestions for the OP based on his initial description of the problem, which is somehow similar to Romanian situation. I quote the OP "The problem is that there either isn't a lot of Pentax gear available here in the UK and what is available seems very high priced." The most important sugestion I made to the OP is to find out the type of photography he wants to approach if he wants his money well invested in cameras or lenses. The name of the system may or may be not important. For people with small budget who predominantly shoot landscape and macro, Pentax is an excelent choice. All you need is a K-S 2, a DA15mm lens and a D-FA 100mm macro (very good lens) and you don't need almost anything else. For this kind of photography done as a passion, the lack of support and the lack of lenses in stores is not so important.

But let me give you a practical example, starting from the fact that the OP doesn't know what he wants to shoot. I organise a lot of photo meetings for people who want to go out to shoot and socialise. In 3 weeks I will have such a meeting and the theme of the shooting is "warrior Vikings". We will have a trained horse, a hawk, costumes, make-up artists and so on. I always invite a known photographer to these meetings so that the participants can have the option to ask questions and learn tips and tricks. There are 10 participants, 3 feminine models and one masculin model. I have 4 Canon shooters, 4 Nikon shooters and 2 Sony shooters. The photo session is in the woods and we have to use fast lenses (at least f2.8 lenses) and flashes in HSS because the hawk will fly, the horse will run and so on. Let's say that I'm a Pentax user who has bought his first camera and I want to participate to this photo session and I have a K-3 II with the kit lenses (18-55mm and 50-200mm). I will have 2 problems at this photo meeting:

1. the lack of a fast lens - I can't rent in Romania a 55mm f1.4, or a fast zoom like DA* 50-135mm f2.8. And I can't buy them either because are not available in store. Ok, let's say that I will use my kit lenses and raise the ISO by 2-3 stops more than the guy next to me who is using a rented 85mm f1.8 lens and I will be able to get some shots
2. the lack of support when comes to trigger the flashes in HSS; I will provide 2 Godox AD200, 2 Godox AD360 II, and a lot of Godox TT685 flashes for this shooting session. All cameras from Canon, Nikon, Sony (even Fuji and Olympus) can be triggered in HSS with Godox triggers and no other tricks. If I give to the guy with Pentax an ND filter so that he can avoid using HSS, the ISO will be even more higher so it's not an option. I will have to buy a Cactus V6 II if I want to be able to help him or otherwise he will be looking at us because he can't shoot in HSS and freeze the bird in flight, or the horse running.

So you see, sometimes the lack of support can be frustating for photographers, even if they have competitive cameras. That's one reason for why beginner photographers tend to go to Canon/Nikon/Sony. They find cameras in stores, they can rent lenses, they can buy Sigma/Tamron lenses if their budget is low, they can buy from the second hand market because there are plenty of cameras/lenses at affordable prices.

Some people acuse me that I bashing Pentax by saying the above or that I'm trolling. I'm not. I'm just trying to say that for some people like the OP for example, the high prices of Pentax lenses/cameras in his country and the lack of available Pentax lenses/cameras it is a real concern, esspecially if the budget is tight. The same problems are also in Romania when comes to available products in store and also when comes to support of Pentax dealer, even if the prices are usually lower than the prices for Canon, Nikon, Sony.

I conclude by saying again that for macro and landscape photography on a budget (at least this is what I understood from what the OP wrote regarding his concerns), Pentax is hard to beat and the lack of support is not that important for these types of photography.

As always, you like to talk nonsense. Correct me if I'm wrong, but there was a guy from Romania who said a few comments back that he had trouble finding Pentax gear in Romania and he is buying his gear from other countries. Basically his comment was related to my initial comment regarding the support that the OP will have in his country for the systems he will invest in. For me, the lack of support counted. For the other guy from Romania who commented in this topic counted also and his decision was to buy his gear from other countries givin the fact that he is traveling a lot. There are 2 guys who tried to say that some support will probably count if the OP will start to invest more money into this beautiful passion and also if he will start to get paid for his work. But soon after you saw our comments, you came into discussion saying that:
- you bought anything you need from Romanian store
- you "tested" and bought a DFA 150-450mm (I can't go and buy one because it is not available in store)
- if your K1 will be stolen by aliens you can go to the store tomorow and buy a new one.

Very well! Aliens will have a very good camera to play with and you will have a new one. What about everybody else? What options does the others guys have if their gear will be stolen by aliens tomorow? What happens if they are professional photographers and tomorow or a day after tomorow they have a paid job to deal with? I gave you a list with some of the most important lenses (150-450mm included) that are not available in Pentax store right now and on the dealer's website it is written "Available on order" not "Out of stock". So, feel free to reinvent romanian language.

You see, some people do go out and photograph. Some even earn money with their Pentax cameras. Those guys wait or doesn't wait for Pentax dealer to bring lenses in store. They either change system, eyther buy from other countries. It all depends on priorities and what type of photography one choses to approach. How many actuations does your camera have since you bought it? If you go out and shoot once a month or even less, then it's understandable why you can wait and buy lenses when they are becoming available.

But you like to start debates like this one because you simply like to contradict with me and go further off topic. Try another approach. Go out and take 2-3 paid jobs and maybe you will understand that there are some things who are not related to cameras performance that can be solved with some support.

Read all my comments. I said that there are 3 things that matter when you choose a system. I don't want to start a disscution about Pentax Romania because it is more than obvious that nothing happened in the last 2 years, unfortunately for Pentax users. And the out of stock lenses is still a common thing here, as I showed you above.

Maybe out of stock means something else to you, but for others means that they buy from other countries.

Back on topic. What I would do in the OP situation:

- sell the lenses that doesn't work for him
- set a budget and start looking for what is available second hand or new in his budget
- rent or borrow cameras and lenses
- find out what type of photography attracts him more (this should be his first step)

From my experience with Pentax, Canon and Nikon, for a small budget Pentax is one of the best choices (if not the best) in terms of cameras: small, very well built, tons of features...

It depends on what you refer to when you said you tested it. Unboxing the lens, put it on the camera and take 5-10 shots for me it's not enough, at least not when it comes to spend more than 1000$.

Speaking of availability of lenses, If I go today on the Pentax official dealer shop and if I want to buy:
- DA* 200mm f2.8
- DA* 300mm f4
- DA* 55mm f1.4
- FA 31mm f1.8
- DFA 150-450mm F4.5-5.6
- DA* 50-135mm F2.8
- DA* 16-50mm F2.8
- DA 12-24mm F4
- DA 20-40mm F3.5-5.6
- FA 43mm F1.9
- DA 21mm F3.2
- DA 15mm F4

I can't because these lenses are available only on order. Like I said, maybe people buy gear based on internet reviews. I'm not among those people. :) If a lens costs less than 300$, then I don't care because it's not an important lens. But when it comes to lenses that costs serious money, then I want to be able to test it in real shooting condition, not playing 10 minutes with it in the store.

When I vote with my wallet, I want to know where my money are going. Luckily for me, the DA* 60-250mm f4 lens wasn't in stock for quite a long period and in the meantime I found someone who had a DA* 60-250mm f4 and I was able to test it. I would have lost 1.650$ if would have bought that lens. Despite its very good optics, it is slow and it has focus breathing. And not to mention that it has SDM problems. And lucky me, I was able to test a DA21mm limited and also a DA 70mm limited, lenses I owned and I was pleased with. But if you don't have contacts to help you test gear, buying lenses based on reviews sometimes it's not a wise decision.

That's why I recommend testing the gear before buying it. Even if the OP can't find stores that rent Pentax, there must be some Pentaxians where he live to contact them and try to test some lenses. Coming from a 55-300mm lens, the 60-250mm lens may be for him the best thing who could happen in terms of lens performance. It's all depending on needs and expectations. :)

To the OP. Maybe there is something wrong with your lens? At f13 diffraction must be quite visible on a crop camera. At f7.1- f8 your lens should have had the best results.

Except 6D Mark II which is not what was supposed to be in terms of sensor performance, 80D, 1Dx mark II, 5D Mark IV have quite a good dynamic range. The difference between my 6D and my 5D Mark IV is quite evident if I want to push the shadows. But I was happy with the dynamic range of 6D because I don't like to push the shadows more than 2 stops and I'm not into landscape. Even if I were, I would use filters and bracketing to avoid pushing the shadows.

But, as I said, if the OP is thinking of buying a cheap Canon rebel camera, it's not woth the effort. Those cameras are screaming poor performance, poor build quality and poor ergonomics.

Owning a full frame is not cheap, at least not if you want some good lenses on it. Without good lenses on a full frame camera, you'll be better with a cheap crop camera and some good lenses. In my opinion, first you have to start comparing:
- prices of the good lenses (lenses are far more important than the camera)
- the support you will have in your country for the system you choose (this depends very much of what you're shooting)
- the second hand market if your budget is tight.

Before I continue to read this thread, I have to say a few things:

1. I have the posibility to shoot with a lot of cameras from different systems and I do shoot with a lot of cameras because it's fun. :) But yes, my main camera is a 5D Mark IV from about 2 months
2. I replaced my 6D with 5D Mark IV not because K1 was released. :) My 6D paid for all the gear I own (including lights and modifiers) and it still is a great performer, despite its age. :) I bought a 5D Mark IV because:
- I was able to buy the camera new (with 0 actuations) with 2300 euro, which is exactly the price of K1 in Romanian stores
- it has 7fps vs 4,5fps of 6D. I had no problems with 6D's af, but 4.5fps were sometimes frustating when I wanted to shoot small and fast birds using 600mm lenses. :)
3. K1 is a very good camera as an all around and very potent option for landscape shooters
4. I can shoot with any camera from Pentax (KP, K-3 II, K1) and have the results I want, even if for action/wildlife I will have to work a little harder to get the results I get with Canon. The cameras are not the main reason I don't use Pentax anymore. It's the lack of support in Romania for this brand. The flash systems was another reason, but it looks like Yongnuo and Cactus solved a few issues. And the last reason was the rent posibilities which for Pentax were and still are non existent in my country. I rent lenses and cameras when I'm in the mood for buying stuff because I don't want to buy gear based on internet reviews.

That being said, despite having a 5D Mark IV, I still love to shoot with 6D because I'm not into specs, charts, graphics and so on. Yes, K1 will blow the 6D in terms of image quality, but 99% of the people who pay for my images don't have a clue about 15ev of dynamic range, 50 af points, 3D tracking, eye af autofocus, etc. :) So, my advice to OP is to try and rent first the cameras/lenses he wants to buy and then look at the support he has in his country for the system he chooses.

Those rebels cameras from Canon (if those are the cameras that the OP is looking after) doesn't worth changing Pentax system.

Two things I don't like about the K-1 C-AF performance

I do agree with you. With practice some occasional action/wildlife can be taken with K1 and we have the proof of it in the 300mm+ lens thread. But K1 is far away from being an action orientated camera and it was never advertised like one. No one with experience in shooting with other systems will say that K1 can compete with Canon/Nikon when it comes to action because it lacks:
- speed (with 4.5 fps you can miss a lot of important moments)
- af tracking performance
- buffer and precessing power; it takes 20s or more for the buffer to clear 10-12 shots

But then again, with practice anyone can have some good action images taken with K1. If you're shooting action for a living, then Pentax is not the right system for the job. If you're an amateour with high expectations for action, then again, Pentax may not be the best option. But if you go out shooting some action for fun and you don't care about the numbers (70-80-90% of images in focus), then K1 may deliver better results than expected. Knowing the camera's limitations, knowing how to deal with those limitations and also with a lot of practice, K1 can do a decent job in this department (action/wildlife). Also, changing a little the mentality can help. Almost everybody who has only 10-15-20% of images in focus blames the camera. I also used to do that. But then I've started to blame me instead my cameras and this pushed me to practice. Better results started to apear soon after I stoped blaming the camera and after I started working on my technique.

So yes, if you want to become proficient in action photography, Pentax lacks tele lenses and tracking performance. Let's see what K3 Mark III will bring to the table in this regard.

I think this guy explains better than Tony Northrup the DOF, bokeh & Perspective between crop and full frame. He doesn't talk about the exposure between crop and full frame when he stots at the same aperture on both cameras, but (if anyone had doubts) from his examples it is pretty obvious that the exposure doesn't change.

It is a wild beast who has found a home. Normally, this bird can't be found in Romania and on it's own I don't think it would have survived because it has only 4 months. But it got lucky. A breeder of prey birds took the hawk and they became friends. Now this bird has a family. The bird is free to fly anywhere, but she always come back to his friend. She is a little afraid of people, but with a little patience (and with some meat), comes very close to humans. :)

Without practice no theory will help us in the field. I heard a lot of excuses such as:
- I don't have time to go out and shoot
- I don't want to waste shutter counts on my camera by shooting everything that moves
- I don't own expensive lenses and I don't own tele lenses
- etc.

Well, I don't have time either to go out and shoot birds as much as I want, I don't buy either a 300mm f2.8L lens because I don't justify spending 6.000$ on a lens that I use 15-20 times a year. I preffer to rent expensive lenses when I want to have fun and costs me 50$ for 2 days. :) But, I'm not going out either and blame each time the camera or the lens for my lack of practice. As far as I'm concerned, you don't even need a camera to practice. I often use a simple metal tube (it is 40cm long, it has a diameter of 12cm and it weights around 2,5kg) and I look through the hole of the tube at the pigeons, sparrows, starling and other common small birds that live anyware and I try to keep them in the frame as long as posible when they fly. Doing that once a week helps me to be prepared when I go out and shoot birds.

So yes, practice helps me to understand a lot of things regarding my camera, helps me improve my reaction speed and so on. To me, if the percentage of missed focus images is under 45-50% with a K3/K1, I tend to believe that:

- the camera/lens is not the primary responsible for that low percentage
or
- the shooting conditions are to bad for the camera/lens to handle (a slow lens in some bad conditions can lead to low percentage of images in focus)

It makes a lot of a difference even when comes to colors and sharpness also, not only when comes to af performance. See the 3 images from below. The first one was taken with a Sigma lens on 5D Mark IV. The other 2 images were taken with Canon L lenses on the same body. The image taken with the Sigma lens has the focus on the eye which is what I wanted, but I'm not very enthusiastic with the details and the colors, at least not when I look at the second image, taken with a Canon L lens.

The third image make look easy to take, but it was not. I was depending on the:
1. right settings of the af
- I was using Expand Af area with one main af point and other 4 surroundings activated; I tend not to use the Expand Af area with one main af point and other 8 surroundings activated because it cover a much wider area than I want
- focus priority for the 1st image
- Case 3 (from the 6 cases available) - Instantly focus on subjects suddenly entering AF points; I customise the case 3 even further in order to match my shooting style

2. the option to change:
- one point Af to expand Af area; I was shooting in portrait mode with single point Af activated but I've customise the camera so that when I turn it from portrait mode to landscape mode, the af changes also from single point Af to Expand Af area with one main Af point and other 4 surroundings activated
- the Af from Af-S to Af-C (Ai servo) on the fly; I've customise the DOF button to change the Af at a single press of a button.

I was shooting the bird which initially was sitting on the ground in Af-S with a sigle Af activated but it suddenly took off in a fraction of a second; I only had time to make 3 moves:
- turn the camera from portrait mode to landscape mode
- while turning the camera I was changing the Af from Af-S to Af-C with a press of a button
- press the shutter and take one picture; I couldn't take another one because the bird came to close for the lens to focus

3. af speed of the Canon lens; with a Sigma 150-600mm I don't think I would have had a chance to take the image

4. the shooting technique - it may sound silly, but from my balcony I see a lot of pigeons flying around and I'm improving my technique by shooting pigeons with tele lenses at widest aperture; I often use the panning mode of the stabilisation with subjects that doesn't move quickly in any direction

Once you find the best settings for af-c from your camera, then all depend on:
- the technique used, which fortunately can be improved with a lot of practice
- lenses used; good lenses offer great results even with the aperture wide open
- how you customise the camera to be able to react in a fraction of a second to subjects that change speed and move erratically

Someone mentioned above that the keeper rate with his Pentax gear was close to 10% when shooting action. It seems way too low, even if I know that Pentax lack behind competition in terms of af-c. I don't have experience with K1 when comes to tracking, but with K-3 II that I had I was getting 45-55% of images in focus in action shots and I'm sure that with the new lenses the keeper rate would have increased with 10-15%.

I hope that the image can be seen properly once you zoom on it. If not, try to download it.

Does IBIS affect precise focusing and exposure metering?
Posted By Dan Rentea

Let's first clarify a few things regarding Ai Servo (AF-C).
1. With only one AF point enabled (spot or single point AF), the camera will focus only where you place the AF point and from there you have to pan or track the moving subject to keep the af on the subject.
2. When you pan or track the moving subject and you have multiple AF points enabled, the focus point can move from one AF point to another in order to keep the subject in focus. But you still have to pan or track the moving subject to keep it in the frame.
3. The EOS iTR (Intelligent Tracking and Recognition) becomes active when you select all 65 point Automatic Selection (or whatever af points has each camera that have EOS iTR). When iTR is enabled you have the option to place the designated starting point over the subject in order to activate the af. The iTR will track the subject as long as you manage to keep any of the 65 AF points on the subject. Automatic point selection is based on sharpness information, color information and face detection information. When it's disabled, only sharpness information is used for af points auto selection. Yes, if you manually select a single af point, then the iTR is disabled. But, like the 3D tracking from Nikon, iTR is best to use it in some situations. Let me give you an example. Let's say we want to photograph horses running on a field. If we have 2 horses that looks the same, camera can get cunfused when you use iTR because the horses color is the same, the faces look the same, etc.

I've talked to a lot of wildlife photographers and 90% of them doesn't use EOS iTR for this type of shooting. They even told me that it slows down a little the af performance. Most of them are using either single point af or the expanded af (1 point with 4 or 8 surroundings) to track birds or animals. EOS iTR is more suited to track athletes or a bride...

Here is what a former Nikon ambassador say regarding fast shutter speeds an Image stabilisation turned ON. I hope I translated right. :)

"1. Do not leave stabilization on when shooting in good light and the shutter speed is 1/500 - 1/800 or faster. Since the operating frequency of the opto-mechanical system is 500 Hz, exceeding the time of 1/500 s will lead to erroneous results of the stabilization system. It is written in the manual without explaining the cause.

2. Do not shoot faster bursts of 5-6 frames / second with stabilization turned ON. Cause - At the first trigger of the camera, the camera starts to produce vibrations, the Image stabilisation tries to compensate those vibrations, but until it finishes, the camera performs a second trigger, producing other vibrations, and the IS needs to do the compensation calculation again. In the meantime, the camera performs another trigger again ... and so on."

What he wants to say on point 2 from above is that by turning OFF the image stabilisation when you use fast shutter speeds, you get rid of the inability of the image stabilisation system to keep up with the the succession of vibration waves induced by the camera when you shoot in a burst.

I took a few test shots this morning with the IS on and off. I've shot from my balcony an old lady who was walking on the alley. The shutter speed was 1/250s, which is a safe shutter speed at 200mm. To make the test more interested, I asked my wife to take the camera and to turn on and off the IS without telling me. Practically, I didn't knew when I was shooting the old lady if the IS was on or off. I really didn't noticed any difference regarding af speed.

Yes, with tele lenses and fast shutter speeds the IS slows down a little the af speed, but with lenses up to 300mm and shutter speeds up to 1/500s, I doubt that the IS has a notable impact on af speed/precision.

Does IBIS affect precise focusing and exposure metering?

I didn't noticed problems with af with non IS lenses. When I bought my 70-200mm f4L IS lens, I rented also for 3-4 days the non IS version of the lens. Both worked the same, the only difference being at low shutter speeds. With the IS version I could shot at 200mm and a shutter speed of 1/40s. With the non IS version I needed at least 1/125s to take a sharp image.

Also, when panning, the IS version allowed me to use shutter speeds of 1/25s, 1/40s.

I didn't noticed any lag regarding af when IS was on or off. At shutter speeds faster than 1/500s the IS seems to slow the af a little bit.

The guy who wrote this article needs some lessons regarding tracking. :D Or he should visit Grant Artkinson Youtube channel. :)

I quote from the article from the link you posted "The downside of Single point selection is that if you or your subject moves, even in AI Servo, the camera will likely lose focus. The AF system does no tracking in these modes so its best suited for static subjects or ones with complex 3d surfaces." I used Canon 6D for more than 2 years, I now use a 5D Mark IV and I'm telling you that what this guy said it's far from being true. And I have tons of images to back up my comments, but it's not a topic dedicated to Canon tracking. :)

I like Oly colors and also the lenses. But the smaller sensor and the EVF makes me skip Oly as a travel camera.
