Re: Eliminating the focal length/aperture change

Thanks Marianne! I should have thought to try that but I will definitely experiment and make this change. Do you have any idea if it would be better to make the change on the lens side or on the camera side of the TC20? This is turning into a nice product......

If anyone has any TC14e or TC17e with damaged optics let me know - perhaps they too can be easily converted. Too expensive to purchase a good one for this purpose.

Cheers! Mark
