New Pentax 645z Boasts a 51MP Sensor with an Insane 204,800 Max ISO

By Anthony Thurston on April 15th 2014

We shared the rumors just before the weekend that Pentax was getting set to announce the new 645z, and it appears that the rumors were true. The new medium format camera comes equipped with a 51MP sensor capable of a max ISO of 204,800 making it likely one of the best MF bodies for low light shooting on the market.

The new Pentax 645z will be offered for an incredibly low price (for a MF body) of $8,500, making the barrier to entry for anyone interested in jumping into the MF world that much easier.

If you have $8,500 available to purchase such a camera, they are now available for preorder over at B&H.

What are your thoughts on the new Pentax 645z? Do you think that a MF option so cheap is a step in the right direction towards making MF more accessible? Leave a comment below to discuss.

    For anyone considering buying a Nikon d800, consider buying this! I would like to see a comparison of the two frankly, but I really think price:pixel is worth it here. PLUS the ISO is somewhat amazing considering most MF cameras never see above 1600. I dont mind the low iso performance, hence shooting iso 100 in the studio most of the time; using flashes in outdoor shoots etc. For those who want to step out of their comfort zone of iso 100-800, this camera will provide you the necessary tools for that.

      I love my D800 and $3000 vs $8500 is still a pretty big gap in price. I’m a huge Pentax fan and, if I was in a place where medium format was a need, then this camera would be sitting very, very, attractive. As it is, I can’t see many D800 shooters seeing this as an alternate, especially when you include lens acquisition.

    MF moving more towards mainstream? Yes and no. Price-point wise, sure. Same exact thing happened recently with full frame and one of the main reasons I now have my EOS 6D.

    No though in that I’ve seen lots of things just stagnate in the “consumer” space. For example, take HD. We still don’t have consumer-based gear that will do broadcast quality video. I’m talking at least 10-bit 4:2:2. Frankly, I’d much prefer getting pro-level features/codecs added on instead of things like 4K.

    So even if MF sensors come down in price which I do believe will happen, I think it too may suffer with some other tradeoffs in the consumer space. e.g. smaller pixels, less ISO performance, etc.

    Looks nice, sadly I have so much Canon equipment already. With all those new announcements I start wondering if Canon has went to sleep.
