Pentax 645Z


The Pentax 645Z offers the incredible resolution and large sensor of a medium format system at a price that's a third that of the competition. It's an easy pick for our medium format Editors' Choice camera.

Captures images at 51-megapixel resolution. Excellent high ISO performance. Speedy response. 2.9fps continuous shooting. 27-point autofocus system. Articulating rear display. Weather-sealed design. Solid control layout. Dual tripod mounts. Optional...

System lacks modern leaf-shutter lenses. Autofocus can struggle with fast moving subjects. Focus points grouped tightly in center of frame. Integrated design lacks versatility of a modular back. So-so video quality. Tethered shooting software not...

Other rear controls include an AE-L button to lock exposure, and a dedicated AF button. There's a four-way controller with a center OK button; its directional controls adjust the drive mode, JPG color output settings, flash settings, and the white...

Pentax 645Z


The Pentax 645Z DSLR is a medium format camera -- a camera with an image sensor larger than full frame digital / 35mm cameras, but not quite "large format". In cinematic terms, medium format is essentially 70mm. It is designed for professionals who...

Pentax 645Z Review


The Pentax 645Z is a medium-format DSLR camera with a 51.4-megapixel CMOS sensor with no low pass filter, offering an imaging area of 43.8mm x 32.8mm which is 1.7x larger than a 35mm full-frame sensor. The dust and splash resistant Pentax 645Z has a...

Coming across very much like a DSLR in medium-format clothing, the Pentax 645Z combines intuitive handling with impeccable image quality in a body that's actually fairly portable compared to its peers. The Pentax 645Z is also one of the most...

Pentax 645Z Review


Medium-format cameras offer truly spectacular resolution, but until now, it's always come alongside a difficult compromise. With the Pentax 645Z, that changes.

Phenomenal resolution and detail; Great high ISO performance; Rugged, weather-sealed body; Huge, bright viewfinder; Fast autofocus works well in low light; Swift performance for a medium-format camera; Good battery life; Shoots Full HD video

Quite bulky compared to an APS-C or full-frame DSLR; Autofocus points clustered near center of frame; Most lenses aren't weather-sealed or optimized for digital; Prone to aliasing artifacts (but so are most high-end cameras these days); Attracts a lot...

Medium-format cameras offer truly spectacular resolution, but until now, it's always come alongside a difficult compromise. With the Pentax 645Z, that changes. Building on 2010's 645D, the Pentax 645Z offers features that are rare or in some cases...

Camera Test: Pentax 645Z


Until very recently, you had to shell out tens of thousands of dollars to get a new digital medium-format camera, and in some cases you'd spend that much on the camera back alone. And if you're used to shooting with a 35mm (full-frame) or...

Hands-on: Pentax 645Z review - Pocket-lint


Is there still life in medium format cameras? Pentax thinks so with the introduction of the 645Z, the second medium format model in its digital line. Replacing

Pentax 645Z review


A bit like a bigger version of the Pentax K-3

Large sensor with high pixel-count ; Tilting, Live View enabled screen ; Familiar control arrangement

High price compared to 35mm ; Heavy ; Bulky

Despite being at the 'more affordable' end of the digital medium format camera market, the Pentax 645Z is solidly built and weatherproof. It's also easy to use and produces superb images with huge amounts of detail.
