Originally posted by Swift1 If you want AF and AE, you should check out the Fujifilm GA645 cameras.
The Pentax 645 is a great camera and very easy to use.
The Pentax 645 cameras would be very familiar to you, as they are large film SLRs. I think of the Pentax 645 as being about at the size/weight limit that you would want to carry around. But plenty of people also carry around the Pentax 67.
The Fuji GA645i is also very nice, relatively light and easy to carry. It's like a large autofocus point-and-shoot, though it does have the ability to do full manual settings. The weirdest (coolest?) part about this camera, is that when you hold it horizontally, the photos you will be taking will be portrait orientation; you have to turn it 90 degrees to take a landscape shot.
A friend of mine has the Makina 67, which seems pretty compact, though I don't know so much about it.
