Retro said:Hmm .. reading through the post, I gather that I should keep my TCON17 if I intend to migrate from an Oly5050 to a Panasonic FZ20.
Confirm again, I will need to get a step down ring or adapter to switch from 62-55mm right?
One question ... any vignetting issue with the telecon? Also, with 12x optical ... has anyone actually had a need to add TCON in? Just wondering only.
You can refer HERE stated vignetting below 7X.
Refer HERE for the comparison between 12X & 12X with Tcon17.
