PETE - Nikon/Sony Shooter
Hi Fernando - decided to experiment with the same lens that you tried as an ext. tube, the Cosina 100-300. They're cheap enough if i dont like it as this one was only £5.50
How far down did you strip yours ? Obviously the glass elements were removed. I can see that getting the rear element off and the mount ring ( MD/Minolta ) would be easy enough, but how do you remove the front element and how do you attach a tube to the front that goes into the focus end of the scope ??
Also, did yours " zoom creep " if held at an angle ( pointing up or down ) I'm wondering if there is a way to tighten the zoom action so it stays firm at any length
