Never said it was brain surgery, but there is satisfaction in doing a simple job well. Part of changing a lens is getting the gasket just so - how many have you seen back to front or rotated away from the groove that receives the lens?You guys are kidding ,right? Undoing two screws ,taking a lens out, putting a lens in and then doing up two screws - down to a fine art ?
Did you take night classes? Is there a special training program.?
For fcuks sake go and see a movie or something!
Haw,Haw,Haw - only kiddin.....................but come on.
