Telephoto for Olympus 3020

Understood.

I run into a strange problem using the Olympus lens tube a 43 ring and a B&W Haze Filter (or any other filter for that matter) where when
using the flash there is obstruction in the lower left corner when fully
wide. As the lens 'zooms' the obstruction goes away and it doesn't happen
without the flash.
I understand you will not be using a flash with a telephoto converter but
there is the unexpected.

I'm also looking for a telephoto converter.
Have you tried this place; # ?
I don't think its a problem since the actually Olympus lens is around 32mm,
I believe.
Also MANY of the teleconverters are built like this. The ones that aren't
seem to be limited to 2X.

Let me tell you, 2X and even 3X isn't very much. I'm considering the
KUT-500. Its a 5X converter but its very LARGE. Not too much of an issue
since its a limited use lens but its sort of stupidly large for its power.
