I sold one to a member on here. He told me that the difference was HUGE! He said the autofocus problems he used to have with the DF (especially with the 300mm) have all been solved.
Hope this helps...
This is the email he sent me :
One day I was trying to use the 300mm f/4.5 AF lens on the Phase One 645AF camera body. The focus motor was very very loud, and the stupid camera never did stop hunting. It just kept trying and trying forever. Even when the image was already in focus, the camera kept tying to focus some more. When I released my finger and half-pressed again, then the camera finally decided to stop focusing, and there was no more sound from the motor. Now I tried the same lens on the new 645DF+, and the focus is perfect. The sound is not loud, and the focus only takes one second in speed mode, and two seconds in accuracy mode. So they really have fixed it, and my 300 is now usable. The new battery will be a welcome addition too. The 300 was the worst. Short lenses like the 45mm didn't give me any focus problem. But I am very happy with the new camera. Thank you.
