Thanks so much for responding guys. I'm so new at all this stuff that I didn't word my question properly.
I understand that crop factor is relative to sensor size. What I meant was what size sensor were each of the lenses designed for. i.e. the Nokton 25m 0.95 is designed for a GH2 sized sensor. Therefore, on that camera it actually provides a 25mm FOV.
Some are obvious, but others I am unclear about. I'm also a little afraid to ask about specific lenses because I don't want to give away the info that Andrew is providing at a price. I don't want to undercut his business!
