Hi,
I am looking for someone who has the skills and apparatus to modify a 13mm aperture-linked extension tube and make it into an 8mm aperture linked extension tube. I'd send the tube to them, they'd do the rest at their own pace, maximum fee for job $100. I don't know what machines or tools it'd require but if you've ever done something like this before or feel comfortable with the idea of this please can you ping me a mail? Bottom line I have 2 10-20mm lenses and I'd like to do some wideangle macro... but the 13mm one makes the focus too close to the front of the lens. I have
one of these extension tubes (all metal).
Thx!
