I'm tired of waiting for FF and wanted bigger files and more shadow detail.
The 645d prices came down to be within my FF budget so I pulled the trigger on a new 645d through Amazon and spent all my FF money. I have a few A primes for my original 645: a 45/2.8, 75/2.8, and 200/4 and those will have to hold me over until my bank account recovers enough to start thinking about new glass. That should also give me a little time to figure out my preferred focal lengths for this format too. I'm thinking I'll want that 35 relatively soon, either the new or old version. Also I was looking at the 33-55 zoom too but opinions seem pretty mixed on that one.
Anyway, it will be here some time next week. I'm excited!
