My sigma 50-500 OS with canon mount has a lot of dust inbetween the first and second elements from the front.
Please find link to a series of images that show how I have tried to open the 1st and the second element. Purpose of both are the same. To get in between the first and the second element to remove the debris.
Both are stuck to the body and do not move at all.
Tried applying some alcohol too.
Link for images taken while trying to remove the lens. http://www.sendspace.com/filegroup/lrtHat22maXN85...
Please help.
