I've been looking for a long prime lens for my SL. There aren't any yet in the SL line. The 90-280 is a great lens, but it is too big for me to carry around for the documentary work that I do. I wonder if the 180mm S lens would work on the SL. It would be an expensive option, but I'm just thinking now about how practical it would be. Would it have full auto-focus and the same auto exposure that the SL lenses have? And would it be effectively a 180 mm lens on the SL?I'm assuming that one needs an S to SL converter. Can anyone help me out with these questions?
Thank you.
