This is an inverse shopping question really.. rather what equipment should I buy.. what equipment should I get rid of, and how to decide.
Currently I have one full frame camera (5D2), and one crop sensor camera (7D). I've just placed an order for a new FF DSLR (5D4) which will leave me three cameras.
What should I look at (including my existing work) to decide which one to get rid of?
(I'm trying to keep this generic and on topic as much as possible, so if you can provide comments for alterations/changes to bring this on topic please do!)
