The new Pentax 645D is finally here, having just been officially introduced by Pentax. For the serious Pro (landscape, outdoor, portrait, fashion, etc.) shooter, this might be a game changer. That is, if they can get their hands on one. Pentax is initially only offering this model to the Japanese market and it remains to be seen what the plans are for the European, North American and worldwide markets.*

So Why a Game Changer?
It might just be for two big reasons:

  • Features:
    • Backward lens compatibility, a feature that has kept many Pentax shooters very happy over the years, is a fundamental part of this design. The earlier 645 series film cameras were quite popular by medium format standards and there’s a very good selection of used lenses around. It’s nice to see a manufacturer respect that a photographer may have a heavy investment in glass and wants to just upgrade the body.
    • Another simple little feature I personally like is the mirror lock-up. It’s a dial on the side of the prism housing you just turn to lock up the mirror. Not having to go into a menu for a feature that will be used a lot while shooting landscapes is a great idea. Many will shoot this camera on a tripod and lock up the mirror to take each shot.
    • Relatively high flash sync of 1/125th compared to earlier film versions (although the Hasselblad and Mamiya competitors do have higher sync speeds).
    • Weather sealed and cold-proof body for the landscape and outdoor photographer.
    • Dual card slots, which given the 40MP sensor is a great idea.
    • Again for the landscape shooter, a built-in HDR function for those scenes with dark foreground and bright skies.
  • Price: The competition at this tier are Hasselblad’s H3DII-39 and Mamiya’s DM40 MF cameras. They are similarly featured yet priced more than double the Pentax 645D’s MRSP of USD $9,500 (direct conversion from Japanese price in Yen). This camera isn’t that much more than the top full-frame 35mm Digital bodies from Canon and Nikon.

Introduced along with the new body is the new weather sealed PENTAX D-FA 645 55mm F2.8 AL, which is equivalent to 43.5mm in the 35mm (full-frame) format.

This won’t be for the sports shooter (medium format cameras rarely are) but for the pro who’s looking at the top end 35mm format digital bodies and shoots subjects where a high frame rate isn’t a concern—they will be giving some serious consideration to this camera.

You can read the entire press release here: Pentax announces 645D, and the new SMC PENTAX-D FA 645 55mmF2.8 AL[IF] SDM AW. You can see some photos of the 645D at the 2010 CP+ trade show in Japan. Here is an interesting interview with Pentax Product Planning executive Yasuyuki Maekawa.

Now time to break open that piggy bank… Buy it at B&H (and help EtL by doing so).

A game changer? The jury is out at the moment and time will tell.

Cheers and good shooting.
