Hi all, New member to the forum here. I have a question regarding the a7r2. I recently disposed of my Canon 5dMk2 to get something lighter and full frame as arthritis in my left hand requires a lighter camera. Here's my dilemma. I held back from disposing of my Canon "L" lenses ( 17-40, 24-105 and 70-200 f4) as my understanding is that they will work perfectly on the sony regarding autofocus. When I eventually purchase the Sony would I be better off if I sold off the Canon glass and invested in Sony glass - some of which doesn't exactly get stellar reviews for the cost/quality relationship or use the Canon lenses instead. I would be primarily using the 17-40 as landscape photography is my thing but would also use the 24-105 as walkaround. I should also mentioned that as I own a NEX 7 I already have two fully automatic adapters - a Fotodiox and a Viltrox. Any advice would be welcome.
