More on the focus tab

I obtained a focus tab for an older model lens and then attached it with 
double sided foam tape. It has been stuck on my new 50 Summicron now for 
about 6-8 months. It is removeable with force and then a bit of solvent 
to dissolve the last of the adhesive that will remain. The lens remains 
unaltered and unmarked. Though I'll never take it off.

The factory tab has two little pins that I cut off so that it would fit 
on the lens without altering the lens.

If you cannot find a factory made tab you could make one from a number of 
materials; wood, plastic or metal and then use the tape to affix it. 
Simply cut the tab material to a similar radius as the lens barrel. Look 
at your 35 or other lens that has the tab as a reference for making your 
new one and positioning it on your lens. 

Clean the area where it will be taped on the lens and the tab. Use care 
and only a small amount of solvent. (acetone, alcohol - something that 
will not leave an oily film) Then stick it together holding it tightly 
for a few minutes. The bond strength increases after a day or two and 
becomes quite strong.

Yes this really does work. The tab stays on.

Now your 50 handles like your 35 with a tab!
