They are extremely helpful. I shoot digital and wanted to try a new lens, they had one used. It has a little fungus on the lens in the description when I emailed them they gave me a full explanation of the lens. It sounded bad but was such a good price I had to go check it out. When I got to see the lens, to my untrained eye it didn't look bad at all. They let me try it on my camera and I saw no ill effects. I will be checking back with them for my next lens.
