With this fisheye lens on my DSLR, I do get almost a full 180 degrees. So, how much less would I get if mounted on the E-PL2, then.
No idea, but it would be comparable to 7.5mm "native" lenses - the actual focal length may not be a totally reliable guide for FE lenses anyway.
I don't know that I'm right, but I'm not sure how this could be true. If the 8mm FE for canon covers 180 degrees diagonally on an APS sensor, how could the field of view on a four thirds sensor be comparable to the 7.5mm FE for micro four thirds which has a 180 degree diagonal field of view on a four thirds sensor?
Seems like the FOV of the 8mm FE must be somewhat smaller on a 4/3 sensor than it is on a APS sensor. Right?
Well, if a 8mm lens can give 180 degrees on APS-C, and a 7.5mm lens can give 180 deg on m4/3, I conclude that the normal crop factor that applies to rectilinear lenses doesn't translate directly in this comparison of FEs. The 0.5mm isn't going to be hugely significant.
EF adapters aren't expensive, I look forward to the OP demonstrating just how different the FOVs are in practice.
