The standard lens for this format is the new SMC Pentax-D FA 645 55mm F2.8. Shorter focal length lenses will be disproportionately expensive, as they always have been in medium format. After all, a 50mm is the most popular wide angle lens for that format (and the cheapest) but it would be pointless on a 645D. The Pentax 645D is up against strong competition from the Hasselblad H4D-40 which uses the same Kodak sensor. The H Series has a well established and mostly satisfied user base, but the H4D-40 costs $19,995 against the $9400 Japanese market price for the Pentax. For the Pentax 645D to succeed, it will have to stay competitively priced against the Hasselblad. $9995 would be a good start. Both these cameras will wipe the floor with the Leica S2. The Leica offers 37.5 MP on a slightly smaller 30 x 45mm Kodak sensor and is already struggling to establish itself in the market, largely due to its exceptionally high price of $22,995. Ouch! There is also the problem of the 3:2 aspect ratio which is not popular in its target market. I predict that the Leica will fail, because sales to Leica diehards will be nowhere near sufficient to make the S2 line profitable.

For many of us, 35mm is hardly anywhere near "big". For that matter, 645 is tiny compared to even 6x9, let alone 4x5. No mirror box or complicated focal plane shutter in that hawse. 5 lbs is a lightweight. ;)
