So, this might seem like a silly question, but I'm thinking about getting a Sony A7S later this year, and want to know which lenses/adapters I should get, and I can't for the life of me understand Sony's mount system: So we have: - E-mount - A-mount - NEX mount (which apparently is the same as E-mount) - ... cropped sensor variants of each mount! Is A-mount specifically for Alpha cameras? It would make sense (α-A), but apparently, it's just a misguiding moniker. I'm familiar with the Sony FS100/FS700 video cameras. They sport what Sony calls en E-Mount. I know I can get adapters for them to use Canon Lenses. Basically, I have lots of good full frame Nikon glass, and would like to know which lenses I can use via a Metabones adapter. What is wrong with picking a name and sticking to it? Nikon F mount has been around for half a century! It's not like the name impacts in any way on quality!
