You should be able to find a used DA 16-45 for fairly little. I have not used it myself but it got quite reasonable reviews. It is an f4 lens. For a little more you could get a Sigma 17-50 f2.8. An excellent lens, my favourite for the K-01. One stop brighter than the DA lens and with a more modern focusing system. Slightly less wide and bulkier though.

Battery issues with *ist-DS

I had a somewhat similar experience with my *istDL when I took it out of storage after a long time. It refused to start up and just showed that blinking battery indicator no matter what batteries I inserted. It finally woke up after I had stored it with fresh batteries inserted for a few days and then worked fine. The problem was not the main (external) batteries but rather the small internal rechargable battery in the camera. When it was completely flat it was hard to get it to start charging again and the camera refused to turn on. Once that was recharged everything was fine. When the internal battery runs out of juice you have to set the date and time the next time you use the camera.

Is the K-01 still worth buying in 2018? Hell yes!

The K-01 is still a great camera after all these years. I use it as a backup for my K-1 or when I want a lighter setup, e.g. when traveling. It only weighs a little over half as much as the K-1 (565 g vs. 1010 g). The image quality is excellent - and always was of course. Most people will probably very rarely need more resolution than 16 megapixels. That said the K-01 has a few weaknesses. Not great for sports due to the relatively slow autofocus (although it is good enough in most circumstances, not with slow telephoto lenses or in low light though). No EVF or OVF, no WR.

Other comparable options from Pentax would be an APS-c dslr from a few years back, e.g. from the K-5 series or K-S2. They are a bit bulkier than the K-01 but with an OVF, WR and faster phase-detect autofocus.

I do wish Pentax would come out with a K-02, an updated version of the K-01. With a more modern sensor (full frame or APS-c) and focusing system and somehow squeeze an EVF in but otherwise keep the body as little changed as possible. Maybe add WR. That would be a great camera and the easiest way for Pentax to re-enter the mirrorless market. It would need a new kit lens though. The 40 mm XS lens never made much sense on an APS-c camera. Certainly small and light with decent IQ but the focal length should have been considerably shorter. A cheap version of the DA21 would have made more sense - or a better designed version of the collapsible 18-50 that they introduced a few years later.

Whatever Pentax releases to celebrate the first 100 years should obviously not be called Pentax LX. That was how they celebrated the 60th anniversary (released in 1980 even if the anniversary was in 1979!). The appropriate model name for the 100th anniversary would be Pentax C.

24-70 alternative lens for K1
Posted By gylfimag
Replies: 43
Views: 3,024
The DFA 28-105 is a very nice lens, good IQ and far less bulky than any 24-70 f2.8 lens for Pentax. If you need something a bit wider and brighter there are a few options, including Pentax's own 24-70 f2.8 and two from Sigma. The Pentax lens is apparently quite good but the most expensive option. I have the older of the two Sigma lenses, with screw-drive rather than HSM. Bought it used for roughly one third of what a brand new copy of the Pentax lens would have cost me. It is a very nice lens and frankly I don't notice any obvious difference in image quality between it and the DFA 28-105. The main drawback compared to the DFA is that the Sigma lens is considerably bigger and heavier. It also does not have WR. The screw drive works well enough and even if the more modern focusing systems, like the one in the DFA 28-105, may be a bit faster, in practice it is easily fast enough on a K-1 body. So, I use both lenses a lot, pick the Pentax one when I want a light package (still something like 1.5 kg, camera+lens) or need WR but the Sigma for low light or when I need 24 mm. There is a considerable difference between the field of view at 24mm and 28mm. Another option is to buy something like the FA 35 to complement the DFA 28-105. That gives you a moderately wide lens with an f2.0 maximum aperture which helps a lot in low light, when the relatively slow maximum aperture of the DFA lens is a problem. I find that duo quite practical. The FA 35 is a very nice lens and quite light and compact and not too expensive (plenty available used as it has been sold since the film era).

Generally not a good idea if you are the buyer, since you risk the seller not delivering, leaving you with no good means to get your money back. Perhaps ok though if you are dealing with a well known seller that has been in business for a long time. Since you are the seller here the risk is less, you simply do not ship the merchandise until you have received the payment. Just make sure that it has actually arrived in your bank account, do not rely on notices of payment or links sent to you by the buyer. Also note that there might be some fees charged by your bank (there are of course also fees charged by Paypal or credit card companies if you go that route), especially if there are different currencies involved. If the buyer starts coming up with excuses for delays in you receiving the payment and pressures you to ship anyway then you will almost certainly never receive any funds!

There is no advantage, only disadvantages, to using PEF instead of DNG. So, the solution is simply to set the raw format to DNG in the camera. It is one of the advantages of Pentax that you can do this.

Why would somebody buy the DFA28-105?

The D FA 28-105 is optically fine and it is probably hard to tell the difference between a photo taken with it and most Pentax prime lenses (at least when you correct for vignetting which is its only real weakness, but that is easily dealt with in post-processing). It has WR, a practical zoom range and is not all that bulky. So, if one does not need the wider apertures that primes can offer I see no reason not to buy and use this zoom lens on a K-1. I use it quite a bit and if I am only taking one lens with me it is quite likely my choice. Replacing it with several primes to cover a similar range is just not very practical in many cases - and for that matter, Pentax does not currently offer any prime lens that is wider than 31 mm (and that lens is 17 years old) so to get to 28 mm one would need a third party lens or a discontinued Pentax lens. That said, an APS-c body with a comparable zoom lens will be considerably smaller and lighter. The K-1 (both versions) with a battery and the the D FA 28-105 is close to 1.5 kg, a KP with the 17-70 is about 400 g less (and of course also costs less). So, the APS-c option has some advantages over the full frame option while the latter wins on image quality - although the KP and other recent APS-c Pentax camera will certainly deliver excellent images as well and probably good enough for most purposes. The compactness of many Pentax primes (certainly not the new D FA 50 though!) is not a huge advantage when the camera itself weighs 1 kg so for that reason primes may even be a better match for the smaller and lighter APS-c bodies than the K-1.

I went with two comparable Sigma lenses instead that I bought used for less than half of what I would have paid for the Pentax versions. Added the Pentax 28-105 to have a reasonably light everyday zoom lens with WR as well. The Sigma lenses are fine optically and very well built so I have no complaints. Don't know how they compare to the Pentax equivalents but would expect the more modern design to perform slightly better optically and focus faster. One (not very important) bonus is that the Sigma lenses are much better when it comes to backwards compatibility with older Pentax cameras as they have screw-drive focusing and an aperture ring. Used one of them on a Pentax LX with no problems (but of course not autofocus).

Pentax K-1 II ISO test images

Very interesting. I am sure we will see more comparisons in the days to come as the K-1 II starts arriving in photographers' hands. These photos are a bit disappointing though, it is hard to see any improvement from the (already excellent, of course) K-1. I frankly can't tell which camera took which photo when they are set to the same ISO. The extra high ISO settings that have been added result in horrible photos, lots of grain, weird colors and banding so they are for all practical purposes useless except, perhaps, for small images converted to black and white. Maybe the K-1 II will show some improvement over the original when shooting in RAW rather than jpeg and post-processing carefully, if not, I don't see any point in upgrading.

Why stop Sigma & Tamron built lenses for Pentax?

The problem for Pentax (Ricoh) is that while 3rd party lenses compete with Pentax lenses they complement the Pentax camera bodies. Since Pentax has such a small marketshare at the moment and really needs to grow it for the brand to be sustainable in the long-term it seems obvious that their only viable strategy is to aggressively try to attract 3rd party lens producers to the Pentax K camp. Sigma, Tamron, Tokina etc. should not have to reverse engineer or license anything, it might even make sense for Ricoh to subsidise their K mount offerings. This might cost a bit in the short run, with fewer sales of lenses (that undoubtedly have a much higher markup than the camera bodies) but might make the bodies more attractive to buyers, giving the K mount a chance to reach a marketshare that allows for sufficient scale economics in the future. Otherwise it will be almost impossible to compete, with little hope of matching the big boys in R&D and without their economies of scale in production, distribution and marketing. That could at best leave Pentax as a niche brand.

Was the MX ever really a pro camera?

Well, I lived through that time but can't say that I had great exposure to the world of working photographers. I did however observe one professional photographer, working for a newspaper in the late 1980's, that always kept a Pentax MX in his car, ready for use. But it was only as a backup camera, he used Canon cameras for most of his work. I doubt that many professional photographers at that time used the MX or the LX although, of course, studio photographers used Pentax medium format cameras quite frequently. The MX was a good camera, reliable and easy to use but not much professional gear was available for it, except perhaps a motor drive. The LX offered a bit more advanced features, including interchangable viewfinders, not just focusing screens like the MX. The metering system of the LX was also state of the art and the body had some weather sealing (but the lenses did not). It probably would have performed well compared to the Nikon and Canon offerings at the time but I doubt that Pentax convinced many professionals to switch. The advanced amateur or prosumer market was more interested, more or less the same situation as now.

This Sigma lens is excellent and should work very well with the K-70. It is though hard to compare it to the three lenses you mention since they are very different. But if you want just one lens then the Sigma is a very versatile option, probably more practical than the trio.

The K-01 was a great camera when it came out (or at least after the first firmware update) and is still quite good. The image quality is excellent and holds up well at higher ISO. Not the camera of choice for sports or other fast action but perfectly fine for most everything else. The focusing system is the main weakness but with short and bright lenses it is perfectly usable, and actually quite OK with HSM lenses. No OVF of course so some might miss that. The LCD is however not bad and even usable in fairly bright sunlight. The controls are simple (at least compared to the K-1 that I mainly use now) but pretty similar to what you would get in an enry level DSLR and have never been a problem for me. The pancake kit lens is fine optically and certainly small and light but I don't find the focal length very useful. It would have made more sense for Pentax to offer something like the DA 21 with it or the collapsible 18-50 lens that they brought out later (although reviews of that lens are not great).

The kit lens is fine but something wider might be good for landscape. The DA16-45 is probably the best low-cost option but you can also get third party manual focus primes that might make sense. WR lenses might also make sense but since the K-r is not water resistant they won't help much if you get caught in the rain. If you are going in July then you will not be doing any low-light photography (except perhaps indoors or in a cave) and you will not see the northern lights in July.

This makes sense. It apparently takes awhile to update these lens databases since it is more than a year since the lens was introduced. The software I tried was all current versions, except Photoshop Elements (I am using version 13). I had expected to have to update to the newest version to ensure compatibility with the K-1 raw files but have not had any problems. I am pretty sure it can not deal with pixelshifted images though.

No lens information for K-1 kit lens (D FA 28-105)

I just noticed that for some reason the D FA 28-105 lens does not seem to show up in EXIF data as the lens used. I tried it with both the K-1 and the K-01 and both on a Mac (Photos and finder) and a PC (PS Elements and finder) with the same result. I tried several other older FA lenses and one Sigma lens and they were all listed as the lens used in the EXIF data. When I used the 28-105 the software just listed 'no lens information'. I could see the focal length and aperture but not what lens had been used. This is of course not a major problem, I hardly ever search for photos that were taken with a specific lens. Still it would be interesting to note why this lens does not show up in the EXIF data.

K-02 FF anyone?
Posted By gylfimag
Replies: 32

A fullframe K-02 should be a very interesting proposition for Pentax. They could reuse much of the physical design of the K-01 and the electronics of the K-1. This would provide Pentax with a significantly less expensive FF model that would cater to a different market than the K-1 and thus not cannibalize the sales of the more expensive one. It would of course not be to everybody's liking - the physical design of the K-01 never was - but that should be fine for a low volume manufacturer. As a long-time K-01 user the only feature I would add is an optional EVF that could be attached to the hot-shoe.
It would expand the market for fullframe Pentax lenses. That is something that Pentax needs so if they don't make a K-02 they should at least make a less expensive FF DSLR to complement the K-1. It could have the same sensor in a simpler and less expensive body. That is pretty much standard practice for Pentax in the APS-C world, selling a rugged, well specified top-of-the line model and at the same time one or two lighter and less rugged bodies missing a few bells and whistles but with the same sensor and essentially offering the same image quality.

The 01 standard prime is a nice lens. It suffers from barrel distortion but that is easy to correct - and if you shoot jpegs the camera will do it for you. Otherwise it is fine, compact and sharp. Its main advantage over the kit zoom is that it is considerably brighter at f1.9 but it is also better optically. The kit zoom is not bad though. The brightness of the prime helps in low light, especially as the Q10 is not very good at high iso. The next generation of Q series cameras, Q7 and QS-1, are somewhat better for low light shooting, although certainly not competitive with cameras with larger sensors. They are also considerably faster than the Q10, both at focusing and operations in general. The 06 telezoom is also a good option, surprisingly good for its size, bright and optically excellent.

I have one and have used it quite a bit since I bought it in the early 1990's. It has been awhile though since I last ran a film through it. My copy works well enough, except the hot-shoe, something disabled that at some point. It is a simple camera, can be fully automatic (aperture, shutter speed and focus) or you can manually set one or more of these. Not very convenient for manual use though. When I do shoot film I usually prefer one of my older Pentax bodies (LX, MX), they are lighter and easier to control manually. In addition they don't have the rather loud built in autowinder that the PZ-10 has. The powerzoom is awfully loud as well and frankly not much of a feature. Nothing wrong with the image quality of the photos from the PZ-10 though - although that depends mainly on the photographer (!). They sell for practically nothing these days so if somebody wants to try shooting with a film camera they can probably get one with a kit lens for very little. They are easy enough to use, pretty much the only complication that you don't run into with a digital camera is loading the film and that is fairly easy to do.

What does LIghtroom do that Elements 14 does not do?

The two programs have a very different approach and are geared towards different uses but there is a fair bit of overlap. Elements can manage large photolibraries and you can tag photos and search by various criteria from the EXIF data, including camera, lens, date etc. Elements can batch process raw files. It is just somewhat easier to do most of this in Lightroom. Elements is however considerably more powerful when it comes to editing although it does not have all the features of the considerably more expensive Photoshop. The editing in Elements is generally non-destructive although you can overwrite jpegs if you really want to. Elements does offer 16 bit editing of raw files although it defaults to 8 bits, that is easy to change if you want to. Not all the tools are available for 16 bit editing but the most useful ones are.

Although the editing options are more limited in Lightroom they are probably sufficient for most photographers. One can also use Lightroom for library management and simple editing and use Elements (or Photoshop) as an external editor, that gives you the best of both worlds - at a higher cost of course and with two learning curves to climb.

If you do some video editing as well then you might want to have a look at the combination of Photohop Elements and Premiere Elements. They use the same library management module for both video and stills and then one is used to edit photos and the other one to edit videos. That can be convenient, especially if you use the same camera for both and thus want to import a mix of video and stills to your computer at the same time. Like Photoshop Elements, Premiere Elements is not the most advanced tool available but not bad and probably good enough for most users.

A normal lens has a focal length that is equal to the diagonal of the sensor. For full frame that is 43.3mm and for APS-C 28.2mm. For the Q-S1 and Q7 it is 9.3mm, for the Q and Q10 normal would be 7.7mm. So 8.5mm is pretty close to normal and certainly not ultra-wide. A normal focal length lens is generally the simplest one to produce and thus they are usually inexpensive and perform well optically.

I have the Q-S1 with the 01, 02 and 06 lenses and they are all quite good and have their uses. The 01 and 06 have somewhat better IQ than the 02 but the 02 is still fairly good. The only drawback with the 01 is a surprising amount of barrel distortion, otherwise it is excellent. If you shoot jpegs the camera takes care of that but with raw files it is more of a hassle although they can be adjusted for this distortion relatively easily. I frankly don't see why Pentax could not design this lens so this was not the case, prime lenses that are close to normal focal length are typically fairly distortion free. If you can live with this, the 01 is considerably smaller than the 02, brighter and with better IQ. The combination is much smaller and lighter than the K-01 with the DA 40mm XS. I also find the field of view of that lens on APS-C a bit too narrow, the 01 on Q-S1 is considerably wider. The battery life of the Q-S1 is considerably shorter than that of the K-01 so an extra battery or two is a good investment.
