I have a Sony A77 and A550 and the glass funkioniert super! The best thing about this Fisheye is the low close range. This many opportunities to inherit to keep creative and funny moments. It's not always on it and I have it already so many times in vain with geschlept forget, but when it is used makes it much more fun and much lÃ'st ... :-)
If you have the money you should really have it ... when standard- Wide, it is not appropriate in my view.
