I am considering adding the Sigma 10-20 lens, but have found it difficult to find many underwater images shot with this lens. I know it's pretty new and that most have already invested in a the Canon 10-22...but I was hoping someone out there had used it and could post some examples and a note on if they have found any problems with it.
From the land shots I've seen and the ideas presented from land shooters this seems to be a very viable lens. I am 95% certain that this is the way I will go...but just double checking for any known problems.
