Digital Camera World Verdict

The Pentax 645Z has not significantly cheaper to buy than when this medium-format DSLR was launched over eight years ago. But given that there are now mirrorless medium-format models available at a similar low price, you can't judge this veteran camera on cost alone. The 645Z is an extraordinarily well-built camera, with excellent ergonomics for its size – and is supported by a lens system that boasts 16 different optical options. But in terms of resolution, image stabilization, autofocus and more - it is hard to justify this camera over the Fujifilm GFX 50S II.

The Pentax 645Z was launched in 2014 - and back then it was noted for being the most affordable digital medium format camera you could buy. At launch its price was around $9,700 / £7,700 for a camera body and a 55mm lens – significantly lower than alternative options from Hasselblad, Phase One and Leica.

But a lot has changed in the intervening eight years, thanks in particular due to the launch of the Fujifilm GFX system - which now offers 50-megapixel and 100-megapixel models that can compete with the prices of full-frame cameras with much smaller sensors.
