It’s a 40-million-pixel, medium-format camera that handles like a DSLR. This digital version of the 645 takes landscape and studio shooting to an advanced level for Pentax users

The competition

The most logical competitor for the Pentax 645D would be the Hasselblad H4D-31, as this offers the same size sensor physically, although with fewer pixels (31 million). Its current price is almost identical to that of the 645D, including a lens. Hasselblad also offers the more resolute H4D-40 for around £13,000 with lens.

The other competition for the 645D will come from high-end DSLRs such as the Canon EOS-1Ds Mark III and the Nikon D3X. Although these cameras offer a very different proposition and only around half the 645D’s resolution, they are still highly regarded for studio and fashion work. For this reason there may be occasions when a photographer would be choosing between a pro 35mm DSLR and a medium-format model, especially considering that their prices are also only around half of the 645D, meaning you could buy a complete setup for the price of the Pentax.
