Re: enabled twice over!

[Peter J. Alling]

The large majority of photos in the sample were shot with digital 
cameras that produce between a 1.3 to 1.7 crop factor.  When you take 
that into account the fisheye doesn't show much line bending at all 
since you've taken only the center portion of the image.  The resulting 
image looks like it was produced with an approximately, (keeping in mind 
that you can't really do a crop factor calculation to the equivalent AOV 
comparisons between 35mm and smaller sensors due to the non linearity of 
the fisheye to begin with), 20mm lens with very bad barrel distortion as 
opposed to a "real" fisheye.

Amita... What's the link to those pics? I just received the 
Zenitar and would also like to look at some other uses for 
the fisheye beyond the crazy/weird effect.

Oh, I love the distortion, and I've been wanting a fisheye for a 
while. The photos I saw on Pbase last night showed me the creative 
potential of using a fisheye beyond just showing off the fisheye 
effect. Plus, I can always de-fish the shots. :)
