Rumors: full frame Pentax DSLR, K-3 specs and a new DA 18-70mm f/2.8 lens

The above picture comes form the Chinese forum xitek and it looks like a Pentax DSLR camera with a full frame mirror box (I changed the brightness of the second image for a better view). For comparison, this is the APC-S sized mirror box of the Pentax K-5:

What do you think - real or fake? Rumors of a new full frame Pentax DSLR camera have been floating for a while.

There is also a new set of Pentax K-3 rumored specifications from the Japanese forum kakaku:

  •  The K-3 will be announced near end October.
  • 20MP APS-C sensor, possibly made by Sony.
  • no AA filter
  • 100% viewfinder
  • black body marketed first, followed by a silver version later
  • price around 120,000 Japanese Yens (US$1200) for the body-only
  • announced at the end of October, on display at the Salon de la Photo show in Paris November 7-11, 2013
  • new DA 18-70mm f/2.8 lens to be announced a well

    My opinion is that this camera is not full frame. The base with two connectors is the same on both photos.

    • P

      The two connector have always the same position since it is used for power zoom lenses (1991). Makes no sense to move it 😉

      • Hmmm… I think it would need to be moved out of the way for the sensor to be taller by 1.5x. I take it it was in the film version? In that case I guess the mirror box and maybe the mirror must already be big enough for FF?

        Still, I’m willing to believe that there are FF prototypes out there. The rumors have been long coming.

  • A-tee

    Absolutely fake, wrong perspective of the inner mirror box, poor PS skill. 😉

  • alreadyupsidedown

    The angle of the mirror box is different from the straight edge on the pop-up flash. Fake.

    • Lee

      ahh…. good catch!

  • MM

    The mirror box actually clearly hasn’t changed in size, one can tell by the relation of the SDM pins and the mirrors edge, however the pentaprism has sure changed in shape, going flat at the front, a lower profile by 5-8mm and lower down at the size ridge when compared with the mode dial height. aside from that the lens release button is much like the K-01 where its more integrated into the body shape.

    • MM

      I should read some of the other comments before posting, yes those angle look quite suspect.

  • Ray3ric

    And $1,200 for body only…in our dreams. You know if/when this thing comes out the body will be close to 2k. Then discounted $500 a day after you buy it.

  • MJr

    Admin come on. You seriously have to ask ? 🙁

  • Sahaja

    Why are such pictures always so blurry? Makes it pretty suspect.

    • Sahaja

      Oh – I was confusing the APS-C K3 specs with the full frame rumour.

  • Canonski

    That photoshopped picture appeared on Xitek in April 2012 !!!!

  • aurele

    the realase button at the buttom left of the mount is different from the K5 / K5-II / K7.

    Looks like a new body 🙂

    For the mirror box, it’s definitely bigger than the one in APS-C line.

  • Marco –

    Pentax should team up with samsung again and build a mirrorless ff compatible, via adapter, with nx lenses in crop mode and with pentax existing lenses. It would kill all the competitors.

    • Tinusverdino

      yeah and use crappy samsuck sensors as well.

      • Marco –

        Crappy? Look at dxo for nx300 figures. But haters just hate 🙂

  • Tinusverdino

    A 18-70 F2.8 would be too big to be usefull there isn’t such a lens on the market for a reason. Pentax probably has a 18-85 F3.5-4.5 in store for us.

  • SomePentaxian

    After all this waiting, I’d even buy a fake pentax fullframe 🙂

    • Duncan Dimanche

      HAHAHA me too

  • 103David

    This would be nice if it were true…but here’s what you should know. As a former camera store owner and Pentax dealer, I was promised a full frame DSLR Pentax repeatedly and constantly for the better part of a decade before I sold the business in 2006. It was always “…just around the corner,” or “…within 12 months,” or…well, you get the idea.
    I’ve always liked their product line and could rarely fault their execution but this became rather a credibility issue.
    So, don’t count on it until you have one (with paid receipt) in your hands. I hope it works for them.

  • Sahaja

    20mp? Pentax may be producing the true D700 successor.

    • Carrera

      There’s a much more recent FF version “in the field”, but
      this pic isn’t it! Whether it ever gets manufactured is an entirely different

  • Bzrkd

    Oh no, please not again!

    These Pentax FF rumours are ridiculous. They go on for a decade already.

  • Narretz

    Does it make sense to introduce a DSLR system now that the move to mirrorless is basically inevitable? However, I don’t even know what lenses you would use with that mount, K-mount or medium format?

    • I don’t understand your comment. K-mount, of course? :/

  • Kevs

    If you’re waiting for a fullframe pentax -switch to nikon…

  • Neopulse

    Oh 645DII where art thou? 🙁

  • The Sky is Falling

    20mpx sensor? 645D in need of an update? Canon wants to work with another MF maker? Doesn’t Canon make a 20mpx sensor for the 6D?
    It is photo rumors after all

  • jairplane

    FF announced together with 18-70 DA lens? I don’t think so
