I have a Pentax 67 II (the latest version) with the AE meter. I found the meter to be extreamly accurate and makes the camera operate just like a modern 35mm film SLR. The 55-100 zoom lens is very sharp and a joy to use.

I have had no problems with 'mirror slap', but the camera is heavy and my experience is that the system demands to be mounted on a tripod.
