I think this started as "It's starting to look like the 21mm D FA isn't going to be released any time soon, major disappointment", to "It's looking like Pentax might not deliver several products as promised", to "Maybe I should start looking for another manufacturer that can deliver as promised", to "What are all the options"... Regardless, well off topic. Sorry for my piece of that..

Nobody talks about this much, but for general photography, a new iPhone is going to do about 90% of the tasks just fine. There really no longer a need for 'low performing' cameras of any kind, including APS-C DSLRs - the iPhone image is going to look just as good on the computer monitor if that's all you're using it for. I've taken great macro photos with the iPhone (I think this is an area where they excel). This might be the true danger for Pentax, in their choice to focus on APS-C DSLRs..

I see what you're saying - take the same software that manages to squeeze really nice looking images from the tiny iPhone sensor and apply it to processing the images produced by the comparatively gigantic 24x36 sensor and the results should be amazing. I think the cameras do provide the ability to customize the jpeg processing functions (sharpening, saturation, etc), so we do have those controls available - most of us probably don't use them to the extent that we should..

All very good points... I've been printing some large panoramas of cityscapes (up to 40" wide), lots of fine detail, so very high res files are needed for tack sharp lines in buildings, etc. At 300 DPI, the 40" print would require a 'native' 12,000 pixels, which is about where the 100MP camera is... of course as you point out, stitching and/or interpolation could easily provide that, assuming the subject is stationary.

I threw out the 100MP figure as an example of where Pentax isn't likely to go, or even be capable of going, even while others DO deliver, as an example of issues that will eventually face the company. Remember, the reason this topic wound up in this thread? It was the apparent inability of Pentax to deliver the promised 21mm D FA Limited in a timely manner.

For me, the 21mm Limited is very, very exciting, a game changer. With that lens and my K1, I would have been mostly satisfied for another few years, until a truly upgraded full frame camera is introduced (using say a 50-60 MP sensor, probably the maximum practical for 36x24 sensor). This all seemed like a great plan, but then I realized, oh wait, the 21mm was announced almost a year ago, now zero mention.. No mention of a new full frame camera... I'm not getting any younger, can't wait forever...hopefully we hear something about the 21mm soon!

Yes, I didn't mean to imply (even though I said exactly this) that 'everyone' is shooting 100MP - what I meant was that, 6-8 years from now, photographers who are trying to produce the absolute best images are going to be using 100MP+ sensors. That group is probably a very small fraction of 'everyone'... I'm essentially thinking of someone who would have been using a 4x5 camera 20 years ago. Point is, I don't think that Pentax aims to keep up, and as others have said, they probably don't have the resources (money, people) to do so even if they wanted to.


I didn't necessarily have this feeling when I bought my K1. With the K1, when released, I felt that I had a camera that was equal to and in most cases superior to every other DSLR available at the time - basically the same sensor as the Nikon D810 at half the price... I don't see a Pentax camera coming that will make me feel that way, given where Pentax is relative to everyone else. That's the crux of my point.

Regarding the diffraction limit at 100MP - absolutely true, a 100MP 'full frame' (24x36) sensor would be pointless (would be diffraction limited at f/4 as you say). Part of where I'm coming from is that there are now other alternatives to the conventional '35mm DSLR' cameras, in packages that are smaller and lighter. The Fuji GFX 100s is actually LIGHTER than a Pentax K1 and uses a 33x44mm array, so the pixel pitch is 3.75 microns, yes that's smaller than the 4.9 micron pitch on the K1, but still usable. By my math, that array would be diffraction limited at f/5.6-f/8 depending on your method.

I'm actually an electo-optical engineer and have always used a simple "two samples per PSF (blur spot)" to choose optics. However, I recently had a project where someone pointed out to me that there can be high-frequency information in the PSF of a lens that can require FOUR samples per 'blur spot' to capture all of the information available (depends on the MTF of the lens). If you believe that logic, and I think it is true for some lenses, then the 100MP array starts to make even more sense.

True, and I guess I didn't explain my point very well. What I'm saying is that if I want to continue making images like this one (which I'd gladly compare to anything from a Sony/Nikon/Canon), at some point there's going to be a need to upgrade my camera to higher resolution, a need to upgrade to the very sharpest lenses (which I'm assuming the D FA 21mm will be - someday)... You can say that 36MP is "all you need", and that the m20 is a great lens, but if the rest of the world is shooting with 100MP cameras and lenses designed in the 2020's, then your images WILL be noticeably inferior (in large prints, etc). I'm just getting this bad feeling that Pentax is getting further and further behind and doesn't seem to be inclined to keep up. I understand the argument that they've really chosen a niche that focuses on lightweight APS-C cameras, light lenses, etc - and I'll always use my APS-C Pentax cameras for hiking and a lot of travel... But if I want absolutely the best image quality possible, I'm not sure I can stick with Pentax, as much as I want to...

Something like this, printed at say 30x40 inches, only using 100MP instead of 36. Shot with K1 and Laowa 12mm. I like spending time post-processing and like printing large... maybe my needs are different than most. Sorry for the trouble folks. I'll try not to disparage the brand in this forum!

Oh, don't get me wrong, I'm getting great images using my K1... I shoot almost every day, win photo contests with it, etc. My point is that I think we've all gotten conditioned to accept that Pentax might or might not ever deliver what they promise (unlike 40 years ago), and it's a bit frustrating to see other manufacturers cranking out products that really will perform better than a K1 with an m 20mm f/4 mounted (using the m-series lens because why?)... I've used Pentax since high-school, for over 30 years now, point is, we'd all be smart to pay attention to what's going on around us and maybe start to consider alternatives. I wouldn't have dreamed of switching brands a few years ago (I've tried Canon and Nikon and know for a fact that Pentax makes superior lenses and cameras)... but now I see the game changing, it's no longer a question of Pentax vs Canikon... and yes, if you're a casual shooter, vacations, etc, you're probably going to be fine with your Pentax from 10 years ago... but if you want to take advantage of advances in technology, and create truly superb images (that wouldn't have been possible 10 years ago), it's looking like Pentax isn't going to be the way to go, again sad to say by someone who has been loyal forever.

Given that it appears that the D FA 21 Limited might be years away, and that there appears to be no activity on developing a new FF body, I'm back to shopping other brands and have noticed just what you've posted - Sony, Sigma, and Fuji are blowing everyone else away in development and fielding truly exciting new cameras and lenses. Take a look at the Fuji GFX 100s - 100MP body that's not much larger than Pentax K1, great lenses... Same with Sigma fp L camera (with Leica mount)... and of course Sony is blowing everyone else away.


It's looking more and more like I'm going to be placing my Pentax K1 in the curio cabinet with my: Asahi Pentax AP, Asahi Pentax S, Asahi Pentax K, S1, S2, S3, SV, H3, H1a, Spotmatic, Spotmatic II, Spotmatic F, KM, KX, ME, MX,... and a host of wonderful old Takumar lenses (20-30)... at some point you realize that it's time to move on. I'll keep the old cameras in my collection, but I truly feel that Pentax is just becoming too slow and too far behind for it to make sense to continue, sad to say.

I actually spent some time looking at the Fuji XT-4 plus 14mm as a good alternative to K1 plus 20mm, but I think for me, it will make more sense to stick with the K1 and this new 21mm... It's a heavier solution, but since I don't own the Fuji, a much cheaper option (and hopefully will .produce superior images). If I were starting from scratch, I think mirrorless APS-C is the optimal choice for lightweight hiking, but alas, I have a ton of Pentax DSLR equipment.

I was thinking of some of the new Sigma primes (14/20/28mm, all way too heavy for multi-day hikes)... I'd be replacing the M20/4 (150g), so everything seems gigantic!

As a longtime/dedicated Pentax user, I'm a little ashamed to admit that I'm just now finding out about this release - somehow this flew under my radar.


I literally have one of almost every Pentax screwmount camera made (including Pentax S), have most every lens up until the FA plastics... and currently am shooting with K1/K3/K5 iis. I mention this back story because I spent the weekend shopping for Sony a7R iv / a7R iii cameras and lenses- precisely because I don't feel that the available Pentax UWA (specifically 20mm) FF lenses really support the K1 36Mp focal plane. Before shopping for Sony over the weekend, I retested my Pentax 20mm lenses and confirmed that they're very sharp in the center, but very soft in the corners on FF (at f/8 'sweet spot'). I shoot a lot of UWA images, interiors, architecture, and while hiking. Many\most successful UWA shots utilize foreground objects to create interest, sense of scale, etc, so soft corners will ruin a large percentage of otherwise well-composed images. Maybe I have unique needs, but for me, this lens is literally the difference between abandoning Pentax and staying the course (that I've been on for 40 years).

For interiors, I already have an excellent Venus\Laowa 12mm f/2.8, so I would use this 21mm primarily for hiking (where 12-14mm is just too wide). Since I'd be carrying this on my back for many miles, I'd not only welcome, but will be elated, if it is f/4 versus 2.8! The world really doesn't need any more big, heavy UWA f/1.8 primes.


Now, if the Sony 61Mp sensor makes it into the next Pentax FF, I'll be set for the next decade or so!

Alas, no tracking email from B&H today, and no charge to credit card. Major disappointment given that I ordered the camera about one minute after they became available. If Adorama is already shipping...

Tracking on the 14mm Samyang that B&H shipped to me on Sunday is shown arriving in Tennessee on Wed, so only 3 days or so... I might be holding the K-1 by the weekend.
