I just recently wanted to buy a fisheye lens to filming skateboard videos, but I came across 2 different fisheyes :

• The Rokinon 7.5mm f3.5 for Micro 4/3

Or

• The Rokinon 8mm f2.8 for Sony E-mount (NEX-7, NEX-5, NEX-3...) + Adapter

The thing is I know the Rokinon for M4/3 is going to fit directly on my camera (tried it in a shop), but the Rokinon for Sony is much faster, but maybe a little less wide...

Can you please help me choose ?

Thank you.
