I just got aSigma 12-24mm EX DG lens. This is my first ever super wide lens. I took a few photos of our home indoors with my 20D. Viewing the photos on my PC, I got very dizzy for some reason :?. Is this normal? I don't know what it is about the photos, but it's certainly different than what I'm used to!

Exterme wides can have interesting effects, but I was using fairly wide 17mm lenses on 35mm before I switched to digital so I kind of like the effects.

Maybe try attaching your image ?

:blah: ya, typical wide angle type distortion.

Extreme wide angle lenses and straight lines don't get along well.
Even though this is a cropped camera, the lens is physically 12mm and gets the neat effects. At least it is not a fish-eye.

Nope, your brain is simply trying to compensate because it knows the distortion is abnormal.

Similar towhen something is slightly blury and your eyes try even harder to focus, even though the thing is supposed to be blurry, but your brain doesn't want to believe it.
