Well, many feel that noise is part of the IR look Tunde, but I know what you mean. You can download the free version of Neat Image to clean up your web sized photos. ;'] Nicely done BTW. :) Jim, LouLouBell has a converted Rebel, perhaps she could give you so feedback about a lense. I assume a good lens is a good lens so you could pose your question in the main forum in it's own thread so it has a better chance of getting seen. I would also be sure to check out the dpreview.com's list of lenses that tend to produce hotspots.
