I'm new , K-x out , K-50 on the way

Hi all - I've had trouble posting - but I'm learning. Just got into Pentax digital since film - I had about all else ! I must say ; I like Pentax RENDITION and SHARPNESS better than ALL others. About 2+ weeks ago I got the K-x w/ DAL 18-55 at a pawn shop for $100. Loved it so much ; I got a DAL 50-200, DA 35 f2.4, DA 50mm f1.8 and a DA 12-24mm f4

I found on Ebay K-50 mint- w/ DA 18-55 4000+ shutters for $249 and $15 shipping. WHY K-50 ???!!! WHY. ! I asked "Bing" Ö?Better Pentax DSLR? since I knew like Zero.

Editor's choice for 2020 = K-50. That seems like a good place to start Ö since I'm further along in (photo-art). And I like that it's about new.

I'm telling myself this will be my 2nd main outfit (I do for the love of it/excellence),but I like Pentax now SO MUCH that 2nd might become #1.

My main outfit right now is Nikon V1(3 of them) - was mainly only MF lenses 10-13 lenses , (hard to nail focus),then added 5 AF lenses

Also have a BUNCH of P+S's to suppliment Ö. I'm on "PhotoWalk2020" till Sept 4th (to donate kidney and 1/3 liver if they let me) and I photo/walk EVERYDAY. Today was day 353.

So far my fav. DSLR lens = the 35mm f2.4 - what glass / what sharpness.

And - the KING of my lenses = (my Zeiss) Ricoh 35-70mm f3.5 version Yes - the rare one that YOU GUYS scored a 10 on sharpness. w/ perfect glass , aperature, and the smoothest focus of ALL my lenses - bad news it is condition 6 otherwise,(hope it doesn't fall apart ! Ö I use this (was everyday) on one of my 2 V1's with me, but now I'm again into lots of cameras Ö so I see what I feel like using each day. Oh - I also have the small version 35-70 compact in E+++ condition Ö and it's quite good ! - Each day on my main V1 I would alternate large version / small version.

Also have 8 mostly compacts to supplement.

Well - I'm hoping to make this K-50 dance+SING. We shall see.

I haven't had much luck yet to post a pic on this site Ö I can't seem to get it right Ö I will try here - now...but I'm NOT going to struggle or get frustrated.

Like-a V1 Larry - I don't know how to do URL-IMAGE. also ; THE WAY BELOW TELLS ME ; to REMOVE(photo) Mine = 183.1 KB , HOW DO I GET TO 128 MB ? My downsized image (same pic) =931 KB size 900 x 892 and it also told me to REMOVE. Your call.

I do have the urge to buy expensive stuff once in a while. I have tempered myself to only buy not just what I can afford, but stuff that doesn't feel too expensive to be a sacrifice in other areas.

I once ignored that advice and I will share that it adversely affected the lives of the people I love.

#5 Very good composition, prop work with tilting the strainer, and having the apples in such great composition. If anything, its a bit dark.

#7 It may not be such a great photo, but the work in making the props, and the concept is pretty worthy of an acknowledgement.

#9 I really like, except that it has weird stuff on the background on the left, like smoke? or some weird form that ruins the shot....so that is my 3rd option. Even #10 has too much distraction from the background.You need to learn how to isolate and create a separation of the focal point intended. Otherwise I really like them.

#15 is also kinda cool, but the green and blue are completely unnecessary and communicates negatively.

#13 Ladies sorting berries or whatever it is is nice, but nothing special, except for being there. Its a bit missing on the meaty info of the file and looks to both sides of contrasts extremes.

#12 Lemon just looks to muddy and dark with no good contrasting info

#1 Is not much of a photograph, but super cute. Toss a criter a peanut and its a easy shot, except this has a slight blur on the hand and peanut, also its not good lighting.

#2 slider burgers are nice, but it just isn't anything we have not seen daily.

#3 Peppers are really great and likely top 5

#4 Orange peeled is neeto, but lacking anything to draw the viewer in

#6 looks like pasta, and I think it is simple and one of my top 5 favorites. Just not sure if its noise or what, but its distracting.

#8 Sungold or small tomatoes is a great photo. It might be in my favs, but there is quality lacking on the tomatoes. I should see more info on them, yet my eyes get drawn to the finger nails and makes me wonder if they need a trimming. :-)

#11 Garlic is visibly exposed, but very sterile and comes out a bitboring.

The FA Limited Development Story (also a little DA Limited)
Posted By JPT

Ricoh has a series of talks at their Shinjuku Tokyo and Osaka locations in the month of November to commemorate the 100 year anniversary. You can see a list of them here.
PENTAX 100???? | RICOH IMAGING

I decided to go along to a talk about the FA Limiteds by Kazuo Ikenaga (池永一夫). Ikenaga-san is now retired but was working there at the time these lenses were developed and is an enthusiastic user of them now, with his K-1 II. He gave a very interesting inside story of their development, and also a lens-by-lens description of their unique characteristics.

Iím afraid I didnít take any photos at the event, but here is an image from the Ricoh Imaging Square Twitter.



????????????? (@RicohImagingSQ) on Twitter

As a big fan of the FA 77mm, I found this a very interesting story and here is an account of what was said. There may be some points I forgot between listening and writing, but it should be pretty accurate. This is going to be a long post.

The concept of the FA limiteds
In the late 90s Pentax was introducing a range of smaller cameras like the MZ-3 and MZ-5, and some people in the company felt they didnít have the quality small lenses to go with them. They conceived the principles behind the FA Limited series.
- The design should give a soft but precise rendering. For example, hair should look like it is soft, not like hard strands.
- The filter thread should be 49mm.
- The aperture should be faster than f2.
- The design is of high-quality aluminium.
- As soon as you pull the lens cap off, the lens should be ready to shoot, without needing a separate action to attach a hood.

Overcoming internal sceptism
The proposal to make these lenses met with significant scepticism and opposition in the company. The Sales department was not at all sure that they would sell. They believed that Pentax was known for more value-oriented lenses, and that customers would not see the value of such small yet expensive lenses.

This resulted in the original plan of a trio of lenses to be scaled down (or rather slowed down) to one at a time. When the 43mm came out, they faced pressure to keep the cost under 70,000 yen, which was very tough. Fortunately, the 43mm sold better than expected. With their concept validated, they were able to release the 77mm and 31mm at two-year intervals and the price was allowed to go higher.

To reduce the initial costs and make the project feasible, a decision was made not to invest in the machinery to manufacture the lenses in a fully automatic way, but instead to machine the parts in a more manual way. This allowed them to release the lenses in the first place, but prevented them from reducing costs as they scaled up production subsequently.

The unconventional focal lengths
What has become the convention for focal lengths used by most companies was derived from what Leica made, but beyond that there was little justification for using those focal lengths. So the designers decided to free themselves from that constraint.

The first lens to be made was the FA 43mm. The intention was to make a classic normal lens to start with, and 43mm was chosen as the optimal focal length to achieve their design goals - faster than f2 and with a filter diameter of 49mm. There was a precedent for forty-something lenses from old rangefinders, and people had found that useful as their only lens. The fact that 43mm was the diagonal of 35mm film frame was not a principle that informed the design. However, they ended up using that coincidence as a marketing narrative when sales felt they needed to justify the unconventional choice.

A similar approach led to 77mm being chosen for the next lens. It sounds like the 77mm was a real technical feat at the time, especially the coating. For the 31mm they must have relaxed the filter diameter requirement.

Unique approach to design and evaluation
As they developed the lenses, they were advised by a famous photographer, the late Shoji Otake. The common practice at the time was to use to use computer aided design and evaluate using test charts. They rejected that methodology for the Limited lenses and instead used a painstaking method of human evaluation of prints. This is understandably a very slow way of developing lenses.

They invested in an expensive, state-of-the-art printing system from Fujifilm. Using the images produced, prototypes with different designs and coatings were evaluated. When they started this practice, the designers were not always able to see the differences, but Otake-sensei could immediately see the significant areas and told them where to look. Once they developed the ability to see the differences, they became skilled in the art of evaluating images themselves. Ikenaga-san commented how much they felt their own eyes improving by being part of this process.

For each lens they made a description of what it should be able to do. For example, with the FA 77mm, they wanted to create a lens that suppressed flare to to avoid washed out photographs. They defined this as being able to depict the glint of a white button on a white shirt. Then they went about the process until they achieved it, and this is why the ghostless coating was applied.

Differences in the concept of the DA Limiteds
Although the DA Limited series has some similarities, there were some different decisions made about the scope of that series. While the FA Limiteds were deliberately clustered close to normal focal length on 35mm film, the DA Limited series was supposed to go from true wide-angle to telephoto on APS-C. Also the DA Limiteds are slower than f2.

There was some talk about the DA Limited series in this presentation, but it didnít go into as much detail about the design story as the FA Limiteds. He did talk about his personal favorites, which are the 15mm and 35mm macro. He also expressed his opinion that the DA 20-40 should be considered more like a prime - a normal with a bit of scope for adjustment. In fact, he seems to be a believer that primes instill better photographic practice.

Close focus ability
The designers took a lot more care about close focus ability than I had realized. The three lenses discussed here were the DA 15mm, the DA 35 macro and the FA 77.

The FA 77 has some kind special mechanism in the design that engages around f2.4 to allow better close focus performance when stopped down. Ikenaga-san mentioned you can feel a little click there if you use the aperture ring, but I canít detect it on mine. In any case he strongly recommends stopping down to f2.5 for the best close focus performance with that lens.

When designing the DA 35mm, they did not start out with the intention of designing a macro. The original intention was to make a more general purpose normal lens for APS-C, but they ended up designating it as a macro eventually.

Left me with a strong desire for an FA 31mm
That basically all that I remember form the talk. It was pretty interesting overall. After doing a quick search to check some information, I found that Ricoh has an article by Ikenaga-san on their website (in Japanese). It contains a lot of the same things he said in the presentations, but in talk he said much more about the development story.

?2? ?????????? FA Limited??????????????/ Beautiful Photo-life | RICOH IMAGING

By the end, I was feeling a strong urge to buy an FA31 by the end of the talk. Perhaps I can justify it to myself one day.

Go to the DPReview site. Bring up the review of the Q7 then on one of the comparison pages you can bring in similar shots from various other cameras. That will give you an idea of how the Q7 compares to other cameras from Pentax as well as other manufactures..

It seems to me that, right or wrong, if thereís one photographic device that doesnít need 4K video, itís a fixed focal length traditionally-styled pocketable street camera...

Put a zoom on it, and that all changes for me, but for what this is, Iím OK with the weak video capabilities...

Deciding to buy a Pentax K1

Hi,

I am a photography enthusiast, more on the lines of physical optics.
Have got several used and new entry to mid-range cameras (film and APSC-DSLRs).

I joined the forum before making a K1 purchase and almost very convinced to buy Pentax K1 and its value for money.

Following are the things that impressed me.
1. Inclusion of 5 axis stabilization system in camera over dependencies on lens manufacturer's stabilization system-Brilliant idea.
2. Anti-alias filters corrections, diffraction corrections algorithms-Another great idea.
3. Simple light to load lens (I wish the dial controls had a fluorescent shade-comes handy in astrophotography).
4. Full color pixel shift corrections for RGB
5. Astrotracker
6. Compatibility to older glass lenses- very environmentally friendly!
7. Rugged design.
8. APS-C option.
There were a couple of draw-backs or not so great features in other forums like WiFi, less videographic features and lower fps. Only lower fps would be of concern for sports shooting, the rest does not matter much to me.
The price range is also very attractive.

I personally have found Sony CMOS very good but Pentax CMOS is already at a pro-level with K1 and K3's and for an amateur like me.
I hope I made a right decision. Further, one of my missions is to use old heavy lenses and shoot in manual modes as far as possible. I think there is a good optical system available and with tools like adobe/ lightroom/ darktable, the rest can be accomplished.

This camera might be contributing to a lot of learning and advance photography skills.

This forum has a lot of experienced photographers, I would like to hear from them on my observations.

Glad to be in pentaxforums.

PhotoPlus Expo 2018

I went to the PhotoPlus Expo 2018 in NYC today and spoke to the Ricoh/Pentax reps, among others. I've got a few pictures from the show, as well. First impressions were that the show was relatively crowded. Needless to say, the biggest exhibitors were Nikon, Canon and Sony, with Olympus and Fuji close behind. The Ricoh/Pentax space was tiny in comparison to the big three, being only about 10-15% of the space of each of the others. The big three exhibits were mobbed; standing room only. Pentax seemed to have a steady stream of visitors, but one or two at a time. The only time that Pentax seemed to have a higher number of visitors was when one of the reps was making a presentation and people passing by would stop to hear what was being said. The presentations were drastically different. The big three all had models on stage with the presenter taking and showing images as they were taken. Visitors were allowed to use the demo cameras and take their own pictures, or even use their own cameras with their favorite settings for comparison. Olympus has been pushing their cameras for avian photography for a while and, in that vein, their model was a large bird of prey! Olympus was demonstrating their ability to focus on the bird's eyes as a highlight of their camera's capabilities.

Even B&H had a huge exhibit and they were busy making sales. I didn't notice much in the way of Pentax in the B & H exhibit, although to be fair, I didn't spend a lot of time (or money!) there. Directly across the aisle from Ricoh/Pentax was the ON1 booth, which was about the same size. They were busy pushing ON1 RAW 2019 by demoing some of its new capabilities and were taking pre-orders for it.

I spoke to the Pentax reps (there were 5 of them) and commented on the fact that their space was dwarfed by the displays of the other DSLR and MILC manufacturers. The response was that they didn't have the advertising resources the others have, which no one here should be surprised about. I specifically asked about a flagship APS-C DSLR to replace the K-3II and, unsurprisingly, didn't get much of a response. The rep did say that there are no plans to exit the APS-C domain, but he didn't have any information that he was willing or able to share regarding a follow-on. I commented to them about all of the angst on this forum about a K-3II follow-on and the rep said that he knows. He reads the posts on the forum, but doesn't/can't respond. One of the most interesting things to me was that he handed me a new Pentax brochure for K-mount Lenses and Accessories. The printing date for the brochure is October 2018, so it's hot off the presses. I've included a picture of the cover in this post.

I mentioned that ON1 was across the aisle from Ricoh/Pentax and I went over to ask them a few questions about some capabilities I felt were missing. First among them was the ability to handle Pixel Shift files. I ended up speaking to their Director of Engineering about it. He admitted that they hadn't done anything about it but also said that they are seeing more requests for it now that other companies are putting the capability into their cameras. He didn't realize that the K-1II allows hand-held pixel shift shots to be made. When I told him, he commented that the new capability may lead to additional requests for it. I'd recommend that anyone on the forum, who hasn't already done it, and uses ON1 and might be interested in using this capability on a K-1II go up to the ON1 web site and support the request for it. He said that he may look into it some more, but additional requests for it might boost his interest.

Now for the pictures. The first two show the Pentax side of the booth, with a surprising number of lenses on display. In the foreground of the first picture you can see a K-1II, with one of the new 50mm lenses on it, displayed under some running water to highlight the Pentax weather resistance. The second picture highlights all of the lenses. The third image shows the extent of the demonstration area at the back of the booth. There were about 5 rows of chairs available for viewers behind me. The fourth image shows the GR/Theta portion of the display, which was on the other side of the wall holding the lenses. The last image is the cover of the new lens and accessory brochure. Unfortunately, the brochure doesn't include a roadmap for the future. That being said, even the rep said that he hasn't seen something like this from Pentax in a long time!

As a quick aside. I also spoke to the Sigma rep and asked him about the possibility of more lenses supporting Pentax and he quickly shot that down due to the tiny market share Pentax holds. He also expressed some disappointment in that, because he said that he started with Pentax (a Spotmatic) and has a collection of old Pentax lenses and bodies. Again, no surprises in that response.

Moderators: if you think this belongs somewhere else, please move it. Thanks.
