Sorry as this is a bit between forums but thought this was the best place to post :-)
After having carried my Pentax 645D on trips as a back-up to my 645Z, I had had one of those moments and decided to try something different and so I am going to replace the 645D with a Sony A7RII, allowing me to cut down on the weight I carry around and also (hopefully) to allow some different types of photography.
Not knowing much about this strange new world of mirrorless cameras, etc. I am wondering if anyone has any experience of using adapters that support mounting my 645 lenses on the Sony and if so, how limited is the functionality? Manual focus is not a problem, but how does aperture, metering and quality fair?
Also, what happens to the "focal length"? I am assuming the 150mm 645 lens, returned to being a 150mm "35mm equivalent" ?
Hopefully the decision becomes a wise one :-)
All help gratefully received.
Thanks
Phil
