2 x converter question.

Post by John flightpath » Mon Nov 27, 2017 9:48 pm

I have just acquired a kenko/teleplus converter for a. Canon ef mount. Does anyone use one of these on a Sigma 150-500 lens. Or is it a no no and you have to use a sigma apo dg converter ?.

Cheers

I wouldn't think it would be a good idea to use a converter of any variety with that lens. I'd expect manual only focusing and degradation of image quality but feel free to try it and let us know what you find out.
