Pentax 645D review – Value

Pentax 645D product imageHasselblad’s latest H4D-31 offers the same sensor size and, with its modular design, is aimed more at studio work. The 645D’s weather-sealed body will be a big pull for those working in the field. The other real competition comes from high-end pro DSLRs, such as the Nikon D3x, that offer around half the resolution for about half the price.

Pentax 645D review – Verdict

The 645D will no doubt attract a niche audience, though its almost-£10k price tag is firmly out of reach for the majority. The experience of using a medium format digital camera is very different from a DSLR and has many advantages, especially for landscape photographers. To be clear: the 645D is less of a studio camera than its competition, but its weather-sealed single body design firmly fixes it as one to use in the field or where large, resolute files are a must. However the vertical run shutter, non-customisable construction and no tethered shooting ability may pose issues for certain users. However its handling is a winner and easy to pick up. For general use a pro-level DSLR still has more versatility but, so long as speed’s no issue, the Pentax 645D is a pleasure to use.
