I've had a bad run on lenses recently and decided to try my luck at repairs myself, I guess I am that kind of idiot!
First lens is an EF 15mm fisheye. I dropped it and the integral metal petal hood got bent. I did manage to straighten it out but also got a brand new one off eBay, but it has a blob of glue on the thread to unscrew the 'hood' and I don't know what to use to dissolve it, anybody got any ideas?
Second lens is an EF 24-70, this is just for amusement rather than advise at this stage but who knows where it will go? It is the first version so it isn't worth much, I went to use it one day and nothing worked, no AF no aperture etc. So after cleaning up the contacts to no effect I figured it was the main board. I looked for a mainboard on the usual sites and they were far too much for me to take a chance with but came across a Dutch site that seemed to sell end of line everything, they had one in it's box for $54 including shipping to the USA. Well that is worth a try I thought to myself and ordered it, the trouble is the site was in Dutch and I had to use Google Translate to get anywhere. Bottom line, I might have a main board coming for it, I might not! I'll let you know.... In the meantime I found a video online of a complete 24-70 teardown and reassembly so took the old main board out.
