Pentax 645z Specs Leaked

Pentax 645z Specs Leaked

According to PhotoRumors, the Pentax 645z medium format digital camera is coming April 14th and will be absolutely loaded. The replacement to the 645d will feature a 52.99Mp CMOS sensor like the new offerings from PhaseOne and Hasselblad, shoot ISO 100-204,800, and shoot full HD video and 4K in "interval mode". In addition, the 645z is rumored to not have an AA filter (like the D800E, D7100) for better sharpness, live view with contrast AF and focus peaking, and a new 27-point (25 cross type) AF system. According to the post the 645z will have an opening US price of $8,496.95.

Below is a quick comparison of the 645d specs against the leaked 645z specs.

    protection against environmental influences is one of the most important details to an electronic camera. Rain or high humidity can lead to corrosion in the camera body. The photographer noted this but only much later, when the workshop requires high repair prices or repair is no longer possible.
    Much faster makes the stay at the beach noticeable. In modern microtechnology a grain of sand is sufficient to allow the tiny motors, and even smaller gear wheels lock and the camera often becomes unusable. With the comprehensive protection program for the 645Z, this camera can still take pictures (even in winter to -10 ° C), if other photographers have their camera better packaged.

Nice specs and seems to be priced well.

Unreal. :-)

damn I want a medium format

Wooooow, awesome pricing too!


Obviously not built with video as a priority, but someone probably could've told them shooting interlaced isn't very useful to any of us.

Well there's an inaccurate blanket statement if I ever saw one!

I don't agree with you. I feel shooting interlaced is a nuisance.

Isn't choppy progressive a product of using too fast a shutter speed?

A medium format camera shooting video 4k ...sounds too good to be true. Let's hope this camera will be as good as it's specs. focusing is a big thing here!

Sensor size and resolution aren't comparative like most people think they are.

only in 2 second bursts though

Dat ISO..

Correct me if I'm wrong, but isn't an AA filter somewhat important for video?

I wonder how long before the world finally gets full frame medium format. Even 60mm x 45mm would be great, but imagine 60mm x 70mm...

Toy camera (vignetting / Lomo effect)


The 1/125th sync speed is a total deal breaker..

As far as I understand, you can still use leaf shutter lenses with PC terminal and get faster X Sync.

I really can not stand the sync speed!

You could probably fit leaf shutter lenses on and trigger via pc... I didn't comb through the specs though...

Thanks for letting me know. What Lens are these, do they AF on a digital body like this?

I don't believe they would. Nor would they have synched aperture control.

Still, MF camera are mostly used in a slow paced part of photography spectrum...

Thanks. I am looking forward to a camera that does higher sync speed and can produce nice files under $10000 range. Like a D800 w' LS. Maybe a D900s will have electric shutter~

Don't hold your breath!

Don't worry, I am not gonna die that way(holding my breath for a year).

I would love to have this camera :) It's so beautiful.
