Pentax 645z scored 101 at DxOMark?

If you look at my previous post on the Sony RX1R II DxOMark test score, you will notice that the Pentax 645z medium format camera is on the top of the list with a score of 101:

Pentax 645z scored 101 at DxOMark
Here is a quote from DxOMark:

The new RX1R II achieved an excellent DxOMark score of 97 points, with individual scores of 25.8 bits for color sensitivity, a wide 13.9 EVs dynamic range at base ISO (albeit slightly lower at base than the best tested), and a very good low-light ISO score of 3204 ISO. In terms of rankings, only the Pentax 645Z with its physically larger 43.8 x 32.8mm CMOS sensor (nearly 1.7x the surface area of a full-frame 35mm sensor) is ahead by just over a half-stop in noise levels.

    Note that when you search the DxO database for tested cameras the 645Z doesn’t show up, but via the DxOMark article on the Sony RX1R II you can get to its test results and also add it to comparisons. The direct link to the 645Z results is:

    • Thanks, I could not find it – I will add it to the post.

        Sorry, I was mistaken it doesn’t show the results.

    Pentax fanbois can finally breathe a sigh of relief…

    • TheInconvenientRuth

      only fanbois accuse others of being fanbois….

      • Spy Black

        That’s a convenient phrase from TheInconvenientRuth

      Canon releases some entry level garbage like SL1 and they get review, score and gold awards in a split of second. But when Pentax releases their flagship camera there is a silence for almost two years. First they ignored and now they are are refusing to publlish results for “best camera in the world”. Nikon had that title and now it is Sony but in fact for last two years best camera was big daddy from Pentax. Dxo have results for almost 6 months but they are still not available. If you don’t believe me than try to find that 101 score, or compare 645z with other cameras. All categories are 0. You don’t have to be a fanboy to realise that something is terribly wrong at dxo.

        Funny that you say something is wrong with them and yet your reason for naming a camera “the best in the world” is based on their numbers, while even those numbers shows its barely (and unnoticeably) better than state of the art full frame sensors.

        • BP2012

          Let me clear this situation, I was not complaining on measurement results, actually I think that technical staff is doing a good job, but their editorial policy is hypocritical.

          Based on my expirience with D810 and 645z, those cameras are not so close in reality as the numbers shows . To simulate dof look from cropped 645 (44×33) on ff you need very fast lens something like 85mm f/1.2 and a lot of work with focus stacking and photoshop merging.

          Btw next generation of Pentax 645 will have full size 645 sensor.

          Merry Christmas!

        They do tend to process Nikon or Canon products much more quickly, since they need the profiles for their software, which is much like everyone else. Still, they seem to delay publishing the test results, especially if they can’t award Nikon or Canon better results.

      Why? More like Sony fanboys if anything.

  • TheInconvenientRuth

    I for one am thrilled that the Pentax 645z has the top score in the “sports” category. Can’t wait to mount a 600/f4 on it and take it to a game.

      Um, neither does the CyberShot. Cyber…Shot. Crowding the sidelines with Cyber.

    • Mistral75

      Help yourself (there is a 800mm f/4 too).

      • TheInconvenientRuth

        There actually IS a 600mm for the 645: SMC Pentax-A* 645 600mm F5.6 ED [IF] but it is MF only.

        • Mistral75

          Indeed. You seemed to care for a 600mm f/4 for your 645Z, therefore I proposed the SMC Takumar 6×7 600mm f/4 (6kg; picture above) and mentioned there is also the SMC Takumar 6×7 800mm f/4 (17.7kg!), which would both work fine with it. Manual focus too.

          • wow 🙂 hope to see some photos from concerts By 645z + this monster 🙂

  • TinusVerdino

    So now that this is known, everybody will have to get one… or not be the best photographer around.
