You're right fast lenses are not important for studio work, but you're
missing the point. If the Canon will do the job and lets face it 16mp
vs 18mp is less of a difference than 6mp vs 8mp, and all other things
being equal, which they're not, the Canon wins on most of the buzz
words. If you're on a budget and who isn't are you going to have two
expensive incompatible digital systems to support or will you use the
one that's more flexible.

to 35mm. All 35mm lenses are faster than all MF lenses in comparable
focal lengths. It's the nature of the beast.

Sorry, you're right 18mp, but the equivalent Canon glass in the
equivalent focal lengths, (actually slightly wider as the canon is
full frame), are f1.4. That's a two stop difference and there's the
Canon 28-70mm and 80-200mm f2.8 lenses. Unless Pentax gets the 645D
street price somewhere near the Kodak DCS 14c they won't be close to
competitive, and that's what they're competing against.

The 645D is 18 megapixel. AS medium format lenses go, the Pentax
glass is adequately fast. I know there's a 165/2.8 and a 105/2.4 on
the 6x7 side. I'm sure there are some equally fast lenses available
in 645 mount.

I'm not worried about Pentax releasing a new APS K mount DSLR, my
referral to the MZ-D alludes to the fate of the 645D. No matter
what P�l believes about the relative equality between Pentax 645
lenses, in cost and capabilities, and Canon L lenses. 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.

Pentax will have at least an APS upgrade when the time is right.
Don't forget, the big seller, the *istDS, has only been on the
market for a short time. You don't release an upgrade until a
substantial amount of your owner base is ready to move up. In the
car biz, I think they shoot for 40%. I think we'll see an APS
camera by this time next year. I'm also quite confident that it
will be at least 10mp, because you have to motivate the upgrade.

Unfortunately, I think that the pessimists here are right, the
most optimistic thing I see coming out of this
is the next MZ-D...

obsolete those
lenses (and have us replace them, of course) in the future?
Pentax probably won't have any choice especially as they career
off in digital 645 land. I don't want to be pessimistic but it's
looking worse for them on every release from Canon and Nikon,
only a blinkered Pentax devotee could call it otherwise IMHO.
Congrats Christian, it sounds like you are now much more content
with your kit, now you can just go out and enjoy shooting with a
future :-)
