I am using GoPro Hero3 cameras. They do a pretty amazing job considering their size and cost. The lens is a 15mm equivalent. The corners are softer than the center and the fall off is worse underwater because the housing uses a flat port. So I stagger the images from the three rows putting the soft corners in the central, sharp area of the overlapping image. Here is an example of an underwater image - in general I find the results are equal to what I get with my Canon 7D:http://www.360cities.net/image/triton-attack-crown-of-thorns-starfish-new-caledonia#358.80,5.70,60.0
I am uploading some above water full resolution crops from the top, level and bottom rows.

AutoPano can do deep focus images from a stack of images taken at different focal distances. But it does not seem to be working too well and sometimes will select the soft areas from the top or bottom row instead of the center row (where I usually have the most important part of the pano).
I have tried changing the optimization parameters but the default settings still do a better job. If anyone has any suggestions for settings that would be a big help.
By the way, I do have PTGui but AutoPano is so much easier to use, takes less time, and has always produced the better image for me. I like AutoPano
