Dude... I'm a professional photographer, I think I know what I'm saying... that is not how it works. hahaha You get wide angles that are 10mm (aka really wide, but not fisheye) & you get some 15mm (not as wide) fisheye's. How do explain that then?
hahaha, ur a funny guy. The sensor has nothing to do with a lens being fisheye or not... try again... there is one main difference & you can see it in the shot quite easily.
Distortion? What do you think that's caused by? The smaller chips don't see as much as the projected image from the lens so it appears like a narrower field of view with less distortion. And stop playing with the props.
Wrong again... Ok, I'll put you out of your misery. A fisheye lens has barrel distortion which curves things, like looking at a reflection on a ball... a wide angle lens tries to correct that curvature & pulls the corners out to straighten the lines which causes another type of distortion completely. I teach photography, you can take my word for it. Next time someone asks a question, maybe keep quiet if you don't know the answer & just want them to look stupid. It's no good for anyone.
So you are saying that a "fish" lens does not project a wide angle field of view? I said it was a wide-angle. That's true. Fishes are wides, but wides aren't fishes.
I have not ignored that. Piojoer asked what made a lens fisheye & you didn't know... it's not just coz it's wide & you went on about crop factor on sensors & all sorts of completely irrelevant stuff to try & explain it instead of just ask or use google or something. You, knowing this little tried to make someone look stupid for asking a question you didn't know the answer to...
