The rest of the new Pentax full frame K-mount DSLR camera *UPDATED*


When Ricoh officially announced the development of the new Pentax full frame K-mount DSLR camera, the press release only included a picture from the front of the camera. A prototype of the latest Pentax DSLR is currently on display at the CP+ show in Japan - here are few additional images from all sides:

    Is that an old MF Pentax lens on it?

    • Resident Lurker

      No. Pentax SMC FA 31mm f/1.8 AL Limited.

      • Spy Black

        So, merely a modern-day MF lens. They should have just thrown an old Pentax 50 on it.

        • Resident Lurker

          If your MF means manual focus, no, you are not even close. 31mm F1.8 is an autofocus lens.

          • Spy Black

            Ah yes, further looking into it it appears to be similar to the old-school Nikkor D lenses. The aperture ring and focus ring with full distance and DOF scale made it look like an old-school MF lens.

          • waterengineer

            “Old-school D lenses” that is funny.

            Funny because it is wrong.

        • Rob S

          You are kidding right? The FA 31 Limited is one of the best lenses ever made. It is an absolutely stunning piece of photographic equipment.

          • Spy Black

            Not by this report:
            http://www.lenstip.com/321.1-Lens_review-Pentax_smc_FA_31_mm_f_1.8_AL.html

            That’s on a crop frame body too. Will be much worse on the FF body.

          • aurele

            If you go to the route of test charts most of the most acclaimed lens for their rendering are trashaccording to those “so great” test charts.

            Keep taking picture of charts and brick wall, if that makes you happy.

          • Rob S

            Thousands of Pentax film shooters disagree.

          • Corbin Dallas

            People like to make this claim, but it’s more often than not false. Yes, crop sensors use the “best” part of the lens, but they also put way more pixel density into one smaller spot of a lens, this leads to a softer image than if the same lens were used on a FF camera.

            https://www.youtube.com/watch?v=YDbUIfB5YUc#t=160

          • Spy Black

            Um, no. You’re using the center part of the lens. Period. And it sucks wide open. Cropped . It’s gonna suck a lot more on a FF body. For the price of that lens specs like that are quite out of date. Unfortunately there’s not a lot to choose from for Pentax FF at this time. Personally I think the older Takumars would be better to use than something like this, assuming they’ll work on that body. If you’re lucky the likes of Tamron and Sigma will start producing Pentax-mount versions of their lens lines.

          • Corbin Dallas

            I shoot both formats with all of my lenses, the FF images are always better, period. Even when using cheap old lenses like my Vivitar 50/1.9. The edges might be a touch sharper in APS-C format, but the image as a whole is softer. So I’m sorry you’re so sucked into measurbating and here-says, but you’re just wrong.

          • Spy Black

            Because you’re comparing the output of two different sensors, which in your case may be working out in your favor.

          • Corbin Dallas

            Again, no. Over the past 3 years I have owned a 6D, EOS M, X-E1, a7R and now an a7S… it was the same story across all the sensors, the FF sensor always yields better results when using FF lenses (though the X-E1 was a little closer).

          • 24×36

            Nope – see my post above. FF is LESS demanding across the entire frame, and will get more performance out of lenses than APS-C, not less, even in the corners and on the edges, with rare exceptions. You need 150% of the linear resolution using APS-C sensors to keep pace with FF performance, and most of the time you’re not getting it, even for corner/edge areas.

          • Spy Black

            That’s the most contradictory video I have ever seen. The effect he’s describing is a product of the sensor(s), NOT the lens. PERCEPTUAL pixels are not REAL pixels. The song remains the same.

          • Corbin Dallas

            Are you even reading what you’re posting?

            If you can’t perceive it what difference does it make? Why are you trying to shoot things that are beyond your perception? The simple fact of the matter is that FF sensors outperform crop sensors when using the same lens, this is part of the reason why there are specially made lenses for crop sensor cameras.

            Here, you seem to not understand what “perceptive” means… http://dictionary.reference.com/browse/perceptive?s=t

          • Spy Black

            If that’s the case, why is he telling you to use a crop sensor when shooting wildlife. The whole thing is a contradiction.

            “The simple fact of the matter is that FF sensors outperform crop sensors…”

            Wrong, sensors with the highest PIXEL DENSITY will yield the most resolution from a lens. That is why he’s telling you to use a crop sensor camera when shooting wildlife.

            Simple physics is going to make a FF lens that is giving you one level of information at the edges on a crop frame camera give LESS information at the edges on a FF body. Below is a chart showing the difference edge resolution between FF and crop frame, in this case a 24mm f/1.7 Nikkor. While the numbers will vary from lens to lens, the end result will always be the same, you’re going to get less information at the edges on a FF with the same lens. Simple physics.

          • Corbin Dallas

            I’m so over arguing with you. Go out and shoot your camera and stop staring at test charts. I shoot both formats, the FF images are almost always cearly better.

          • 24×36

            You conveniently forgot to “normalize” your comparison. you’ve got more lines/mm (or line pairs/mm – not sure which Lenstip is using), BUT you have LESS “mm” on the APS-C sensor. Let’s look at what appears to be the biggest “difference” in the mtf values in your chart (f4). The FF gives you 29 lpmm, the APS-C gives you 35 lpmm. Even with lower lpmm, the FF sensor will in fact have MORE “information at the edges,” since the APS-C sensor will have 546 lines (1092 if Lenstip uses “pairs”) PER PICTURE HEIGHT (multiply lines (or line pairs x 2) by sensor height), while the FF will have 696 lines (1392 if Lenstip uses “pairs”) PER PICTURE HEIGHT (again, multiply lines (or line pairs x 2) by sensor height).

            “Better edge/corner performance” for APS-C is a myth. You’ll only get there with the exceptions (the very best glass, or glass with bumpy mtf profiles or truly massive edge/corner falloff that happen to favor the APS-C image circle cutoff). Basically you need 150% of the linear resolution to match FF performance on APS-C, and most of the time you’re not getting it, even in the corner/edge areas.

          • Spy Black

            That’s the most contradictory video I have ever seen. The effect he’s describing is a product of the sensor(s), NOT the lens. PERCEPTUAL pixels are not REAL pixels. The song remains the same.

          • Arn

            You have to understand than Pentax didn’t try to achieve the maximum resolution only on the focal plane, but on a larger area. It makes them bad performers on testing benches.

          • Type

            As someone who has used it on almost every Pentax body since the K10D, and who has owned lots of high-end Nikon/Zeiss glass too I advise you to disregard that review from a real-world user perspective. The lens can produce simply stunning images, as can the 77mm Ltd. Wide open? Yeah, it’s not a Sigma Art lens but I’ve had exactly one situation where wide open was required and even then, it still took a lovely picture.

          • Spy Black

            As I said elsewhere, in the end it’s what you do with the lens that matters. 😉

          • Yes… at 31mm maybe… lol

  • Corbin Dallas

    Ewwww… I was excited for the Pentax FF rumors because I think Pentax makes some of the best looking DSLR’s out there, but this thing is beyond hideous.

    • jojo

      Don’t worry too much, it looks a very early concept model –
      there’s presumably plenty of scope for change.

      • Corbin Dallas

        I understand that this is only a prototype (obviously), but the’ve got a lot of work to do to make that thing look decent or comfortable to carry around all day… maybe I’ve been spoiled by the a7 line.

    • SimenO1

      Good thing that this 3D printed non working plastic brick never will be sold. I think the ergonomy and size looks promising. Looking forward for the final camera late this year. 🙂

    • Cinekpol

      Then I guess you’ll be delighted to see previous Pentax Full Frame prototype, the MZ-D: http://2.static.img-dpreview.com/files/p/articles/2734370763/pentaxdslr01.jpeg

      • Luis F. Vidal

        Oh my god! It is a genetic disorder!

      • 24×36

        Heh at least this time we know that someone can deliver a quality sensor, and that the camera won’t cost $6,000.

  • Hubertus Bigend

    I wouldn’t call a 3D-printed, solid piece of plastic a ‘prototype’…

    • JoeJohnBear

      right?! wtff.

      • Daedbird

        Actually, there is a better ‘prototype’ that was unveiled during CP+ that includes the screens. A comparison with that model and the K3 can be seen at http://forum.xitek.com/thread-1418129-1-1-1.html

        • Thanks, I will add this to the post.

        • Kunzite

          I really don’t think that’s a better prototype, just a photoshop job over the same mock up.
          The working prototypes remains hidden.

  • SH*T666

    I really hope this is not the real thing with that tiny VF and no tiltable screen.

    • aurele

      PentaxForum did interview two men from Pentax, and they said the screen with be tilt and swivel.

  • Spy Black

    I hope that thing is ergonomically functional, because it’s pretty butt-ugly otherwise.

    • Dom

      You pick cameras by the look?…well, do it in your way, I pick the camera by the sensor and features.

      • Luis F. Vidal

        At the end that’s what really counts. But is really great to have something that whe you look at in the table inspires you to take photos. That thing doesn’t look inspiring at all.

        • markz

          I’m generally am inspired by landscapes, buildings.. people… if a camera inspires my it’s because I want to shoot a picture of it not shoot pictures with it.

          So what ever lump of plastic, metal, and glass I’m holding in my hand I’m looking through it, not at it.

          • Corbin Dallas

            You’re still going to be looking at it and lugging it around. Saying that it makes absolutely no difference I think is just a straight up lie… maybe not to us, but to yourself.

          • markz

            Corbin Dallas, ah no, not at all, you should see some of the pigs I lug around.. if you like certain eastern European 35 and medium format glass (like I do) pig ugly comes with the territory, besides the proof of the pudding is in the eating, and the proof of the camera/glass in in the image so yeh I couldn’t give much of a toss about what the camera looks like I’d even buy one of those chunderblads if they were reasonably priced and not just rehashed Sonys

            if your buying a camera for appearances then please don’t mind me while I snicker behind your back (hell I’ll snicker in front of you, and you wouldn’t be the first)

    • Cynog

      Beauty is in the eye of the beholder. I think it’s quite good looking and purposeful. That prism hump is reminiscent of the classic MX. And I don’t think it’s all that big – probably smaller than my D810, but it will be built like a tank. I don’t like tiny cameras, anyway. And I think the A7 series are the ugliest cameras around! Each to his/her own. I’m buying.

      • Spy Black

        “Beauty is in the eye of the beholder.”

        Fair enough.

    • Denis

      Pentax cameras have amazing ergonomics despite the looks. I’m sure this one will be no different in the end.

    • Kunzite

      What badge should it have in order to be ‘beautiful’? 😉

      • Spy Black

        K-r and K-5 come to mind. Far better-looking cameras.

        • Kunzite

          The mock-up follows the design line started with the K-7…

          • Spy Black

            It may be argued that, but it’s a bad hack of the design. The K-7 and K-5 both share a similar design with tapered sides, a wider prism, rounded corners, and a softer cut on the grip, among others. Much better-looking:
            http://www.imaging-resource.com/PRODS/K7/ZURFRONT.JPG

          • Kunzite

            But you’re comparing a finished product with a 3D-printed mock-up. Details are subject to change.
            For me, the pentaprism shape doesn’t ‘break’ the design. Perhaps it doesn’t fit as well as the on-board flash design, but I’ll wait to see the real product before judging.
            Anyway, it’s ridiculous to call it “butt-ugly” – compared to the shapeless blobs some other brands are making, it’s a beauty even in this incomplete form. And it’s not a failed retro design either.

          • Spy Black

            3D printers are not lacking for detail. That is the shape they wanted, not some rough approximation. Hopefully as you’ve said details may be changed, and hopefully in the direction of the K-7. 😉

            Of course, as someone else put it, beauty is in the eye of the beholder, but I do indeed find it, as it is, butt-ugly.

          • Kunzite

            Yes they are – different materials (painted metal with rubber on the grip and other parts), all components (e.g. the monochrome LCD), real doors/port covers…
            But I’d guess in your case, you don’t like it because it’s not “your” brand.

          • Spy Black

            No, that is the shape they want. Just because it’s not “my brand” means nothing. “My brand” has it’s own butt-ugly designs (the J series immediately comes to mind). The K-5 and K-7 are attractive camera designs, and it’s only a few curves and tapers difference. Amazing how such subtleties can change the look of a camera.

  • fjfjjj

    It’s a beast!

  • aurele

    At last ! The unicorn is real 😛

  • Camaman

    Yeah Pentax!
    A true A7 competitor! In your face world!

    • Cinekpol

      You mean – that’s the only FF camera that Pentax can beat in the amount of available lenses? Yea, it looks so. Sadly though – Canon, Nikon and Sony A-mount can build a pyramid from lenses on top of that Pentax.

      • SimenO

        I dont think lens selection will limit many photographers. Excatly what lenses do you miss?

    • Corbin Dallas

      How in any way shape or form is this thing an a7 competitor? It’s twice the size, likely twice the weight and it’s a DSLR (limits your lens selection).

      It looks more like a 5D and D800 competitor to me, which is great, but lets not go labeling it things that it’s clearly not.

      • Camaman

        Thats what I meant! I was being ironic.
        This brick would be a competitor on the market only if it was 2005

        • Corbin Dallas

          Ah, I see. So hard to convey sarcasm over the internet sometimes… lol.

          • Camaman

            So true. Texting even more so. And that can way prove more damaging to your personal life

      • Kunzite

        You mean it’s the proper size, proper weight and it’s a proper, DSLR camera. Not one of those flimsy things needing 3rd-party reinforced mounts so it won’t break with any lens heavier than 20 grams :p
        The camera has more native lenses 6 months before its launch than the A7.

    • Neopulse

      LOL wtf? Hahahahahaha!

  • Narretz

    Just a mock-up – doesn’t inspire confidence that the camera will be shipped in 2015.

  • Skinny Pete

    The body is bigger than I expected. But it’s early days. I’m still very interested in hearing what auto-focus system they’ll implement.

    I’m hoping Pentax will periodically release (or leak) some specs to keep people’s interest on high alert. And lenses info too. I know the 31, 43 and 77 are great lenses but they are long in the tooth. I fear this sensor may show their weaknesses.

  • Luis F. Vidal

    Damn! That thing is ugly! It looks like it weights 30Kg.

    • SimenO1

      Also it looks quite compact. That adds up to high density, meaning solid and rough construction. Not the kind of Ikea plastic lunchbox you get when you buy a Canon 70D.

      A large pentaprism is heavy and means a large good view in the finder. I love large finders but cant afford medium format. Also digital large format viewfinders is quite small compared to film.

      • Luis F. Vidal

        Nice point of view.

  • George Kalogeris

    Now let’s hope they throw inside the a7s sensor and I’m willing to sell my D4s

    • Neopulse

      Hope they don’t, would destroy the point of it.

    • SimenO

      I belive they will put the 50 Mp sensor in the first one and follow up with a 12-16-20 Mp sensor in the next one.
