There is at least one important aspect where the 645 lenses fall short, speed. You don't see too many Pentax Medium format f2.8 zooms. or for that matter f2 or faster primes. That alone will put the the 11mp Pentax 645D at a competitive disadvantage with the Canon 16mp EOS based DSLR. Pentax will see the writing on the wall cut their losses and not ever release it. That's bad enough."
REPLY: The lack of fast lenses for medium format (film) didn't stop MF in being a viable alternative. The fact is that fast lenses isn't needed. Using 1000ISO slide film an a 645 gives equal result as 100ISO slide film in a 35mm camera with a fast lens. Granted, you won't get the MF advantage but you are not handicapped. For digital the relations will be similar. Besides, high-quality digital will probably be prefered for nature/outdoor and studio use where lens speed isn't that important. Often, faster lenses are less desireable for hese purposes due to lower optical quality and more flare. P�l
