I know there are threads on this, but I'd like to get opinions specifically from OWNERS of the Samyang/Rokinon/Bower/etc 7.5 Fisheye lens. (Fun fact: Even though I drive by the factory where they're made a couple of times a week, I can't find it in stores ANYWHERE...gonna have to order it online). G.A.S. is hitting me hardcore, and I've been loving the fisheye thing lately (never used to think much of it). I have a UWA zoom and a couple of fast primes (9-18, O45, O75), and was going to get a fast 20/25, but I think this would give me a more unique shooting experience and open more possibilities for fun! How do you like this lens? How's the sharpness/contrast, especially? Would I have to switch my OM-D to "shoot without a lens" every time I mounted this lens, or just pop it on and fire away? How does the light meter work with the manual aperture? I tried the Nokton 25 (full manual everything) on my OM-D and just popped it on and started shooting...is it the same deal with this lens?
