Questions for you (if you own SD1 and DP2m)

I have the DP2m now, and finlly I can justify using 44 inch printer!

I am thinking about getting the SD1 since I want more focal length versatility yet I have to have that great sharpness and resolution (I hope) that dp2m provides. Is SD1 as sharp as DP2m? Which lenses would you reccomend? I like primes, but a sharp zoom can be very useful too.

Thank you for your suggestions.
