Hey thanks a million Michael, and others who have contributed! Just bought a Rokinon 14mm and this thread has a wealth of useful info for me - answers to questions I didn't know existed and new questions I should be asking. I'll post them on the board as soon as I think I can intelligently pose them
Some time ago I published a beginners guide to manual lenses on the sony a7 most of the advanced users here probably won't learn anything new but if you are abeginner it could be helpful to learn the basics of using manual lenses on the Sony Alpha 7
I thought this was worth posting for easy reference ... from the Zeiss Lens Blog;
"Over the course of time ZEISS has published a lot of interesting technical articles about the physical basics of camera lenses. However, after some years not every article can be found that easily. Thatís why we decided to publish them all in one blog post to give you easy access."
