as dim as the shutter is loud
quartz display and rubber control button
electrical contacts star playing games over time
There s no getting around the noise of this camera
Too many are simply trying to capitalize on affiliate revenue
my camera looked too professional
massive optical viewfinder
You get lost inside the photo shooting process
the highlights slider to recover detail in the highlights
The bigger
heavier
and bulkier your camera
the 645Z is pretty limited compared to the Canon
the processing side can be a bit of a pain
Had very poor to non existent high ISO support 3
horrifically expensive
The buttons on the camera are pretty predictably placed
the current tech in there is slow
Slightly soft wide open through the zoom range
turning lens profile on in LR would double the effect
the image looks different to CCD

Pentax 645z Medium Format Digital Camera Review

We just spent a week shooting the new Pentax 645z, the new, somewhat-affordable medium format system. We wanted to take a real world approach to how we would test the camera, so like most reviews on Fstoppers, this will be less technical and more about how it performed on the job. It was put through its paces at full wedding, a weeks worth of portrait sessions and a night shoot. Why Medium Format? Medium format digital cameras have been on our mind lately, as the market is at an interesting point.

Camera: Pentax 645Z

Medium format digital cameras used to be essentially film cameras fitted with digital camera backs that contained an image sensor. In this way, professional photographers could keep using expensive gear that can cost as much as $50,000, and not have to buy a whole new system with an integrated camera back. Then in 2010, Pentax introduced the 645D, a medium...
