Interesting.... I have thought about picking this lens up. How long have you had it for? Have you liked it?

Someone was using the 645z at my studio the other day. I chatted them up about it a little bit and they said they love it! They use it mainly for portrait work but he said that some of his product photography clients actually require him to use a camera like that for the job. So it has actually made him some new money just from having it!
