how is it? user interface and features compare to your old body. what did you do with the old body? have you upgrade your old sensor yet?
It's vastly better. Auto focus is much faster which was the main problem with the old body. I have not had a chance to use it for a full day of studio shooting yet because everyone is on holiday. Will be able to get a much better idea towards the end of January when everyone's routine goes back to normal.
I am not getting a new back. The IQ160 is perfectly good and it would not be worth my while to upgrade just for a few extra features. The upgrade would set me back another $10,000 at least and would not get me any better image quality.
