Fisheye lenses corrected and resolution loss
I'm interested in buying something wide for my D3100, however i rarely have the need to shoot wide, but occasionally i get the urge to do so. Therefore i thought about perhaps a fisheye prime, since i believe they are cheaper than normal wideangles?
What resolution and quality loss is there actually in the corners when one corrects it post? Would be interesting to know, thought about trying someones RAW file out and correct myself and see but i fail to find any.
