Review: The Pentax 645Z, part II: compared to the 645D, Nikon D800E and Hasselblad CFV-39

The contenders. From L-R: Pentax 645D, Pentax 645Z, Hasselblad 501CM with CFV-39 digital back, Nikon D800E.

Four cameras, 166 megapixels, no sensor smaller than 36MP and 36x24mm. It’d have been nice to get the Phase One IQ250 and Leica S along for the ride too – sadly there’s no Phase distributor in Malaysia and nobody from P1 has ever replied any email I’ve sent though. So we’ll make do with four: two from the old CCD guard and two from the new CMOS challengers. Lining up on the right are the Pentax 645D (33x44mm, 40MP) and Hasselblad CFV-39 on a 501CM body (49x37mm, 39MP) against the Pentax 645Z (33x44mm, 51MP) and Nikon D800E (24x36mm, 36MP). Perhaps we should have gotten one of the 41MP Nokia PureView phones along for kicks, too. That said, the rationale behind these choices is as follows a) I had access to them; b) to build a more or less complete system would be roughly the same price; Nikon and Pentax new lenses are more expensive than the used screwdriver Pentax FA or Hasselblad V glass; by the time you add everything in, the 645Z is obviously the most expensive option – but also arguably has the highest IQ potential. Welcome to part two of the Pentax 645Z review – the first part can be found here.
