I have just past the 10,000 frame mark on my 645z, its at 10823 and sleeping for the weekend.
I got it a couple of months ago and have been using it almost exclusively for my advertising work. I'm very happy with it so far, for the most part.
Here are my top TEN lists for it
Some thing that do bother me though are,
1. AF zone is too small (center 25% of the frame only)
2. inconsistent AF accuracy
3. wait time to use the aperture and ss wheels after firing off a frame
4. the grip, too small
5. SD slots too close to strap point, relocate the strap mounts please
6. missing cap for PC connection
7. wait time to turn on LV after firing off a few frames
8. cable release option besides FluCard
9. FA collar AF/MF switch, PITA
10. tunnel like viewfinder, your eye needs to be lined up perfectly to see 100% of the frame
things I love, beyond the resolution, decent lenses (for the money), ISO sensitivity
1. rear monitor, huge
2. dual SD slots, my Mobi wifi card works wonderfully at speed with the camera
3. weight, nice balance
4. solid lens mount
5. side tripod mount
6. comprehensive menu
7. Live View magnification, the only true way I have found to get accurate focus
8. Matrix metering is usually spot on
9. Long battery life, one battery lasts almost all day, around 1000-1300 frames even with the wifi card transmitting
10. Three WB preset favourites, great to swing back and forth through while testing a scenario
I don't use the camera everyday. I now have three systems from 3 separate brands that I use on shoots; Pentax 645z, Nikon D800 (lightweight back up to the 645z) and the Canon 5D mk3 for lighter file size work.
Saying that, I'm working on a 25 day project, shooting 50 locations with 50 hero shots and over 450 extra scenarios. I'm half way right now and the Pentax is shining. Most of the time I don't bother using the other cameras for the smaller or lighter work because I'm enjoying the the Pentax especially with the 45-85 and the 35 prime. The Nikon has been consistently jamming when needed the most and the Canon now feels like a Fisher Price toy.
When I'm done this project I willing be thinking about sending the camera in to have all the lenses calibrated with the body, specifically checking the focus.
Overall I give it an 8.5/10
