I had a couple of weddings last week and it was the first time with the AFD + Kodak 645M.
I really enjoyed using the camera and was really happy how it handled in the field. Having experience with the SLR/n, I was also very happy with the ISO400 image quality.
The only downside so far is the noise of the mirror. It's very noticeable in a quite church.
A second one is now on my shopping list. I hate the time it takes to change lenses.
