I'm going to upgrade lens before upgrading camera. What I would like to know is whether APP would work better with rectilinear wide angle lenses, or with a fisheye lens. Or does it not really make any difference?
I'll be doing landscape, cityscape, and indoor panos. I also want to do some night time lightning filled panos, so something fairly wide would make those easier to do under the pressure of storm activity.
Do you have a suggestion for a Canon or premium after market brand lens? At this point I don't know if a later upgrade of the camera would be a 50D or 5DmkII, so it might make sense to give 2 suggestions if they would differ for APS-C vs. full-frame.

Circular FE - The Sigma 8mm f3.5 (4-around+Z+N)
Fullframe FE - the Sigma 10mm or Tokina 10-17mm FE. (6-around+Z+N)

Yes - i do. As i said, i compared it to Sigma and Tokina on a Canon 20D. In my eyes their capabilities to use highres cutouts are limited - not only naturally in final resolution but due to CA and stry light.

WhatÂ´s making you think so ? Besides: thereÂ´s no rectangular lens with the focal length of a fe!

hankkarl wrote:Not sure what you mean why you never found any serious attempt to ponder ... lens types for spherical panos. Do you mean you like FE lenses because the center is better than on Rectilinear lenses, and is more important?
hankkarl wrote:Sharpening gives you a chance to correct mistakes, etc. The lens is critical--you can add accutance (ie a sort of contrast) but not resolution (the sharpness of features as opposed to the contrast of the feature and background)
You cannot remove blur, you can only fool the eye into thinking it is less than it really is. So sharpening and other post processing are things we all try, try and try again (for the cost of our time) while lens resolution and contrast are something we cannot improve except by buying a new lens (or calibrating the lens)

My first opinion was that fisheye could be better because, as they use an "equisolid" projection (or about), they insure an equal repartition of image pixels in every direction. Then I realized that next to the circumference of the image circle they make a very unusual use of said pixels ! (when distorting shapes along this circle.)
