Question Using 2x Converter with EF-s lens, canon.

spooky donkey

Hi bit of a question for the techie guys here.

Recently I got a loan of a Tamron 2x AF converter and I have used it with my 24-105 on my full frame camera fine.

Will it work with EF-s lens on my crop sensor camera?
Also will it allow me to use an EF-s lens on my full frame camera. My under standing is that EF-s lens can damage your mirror on the full frame camera. So im thinking the extender will take the EF-s lens away from the body...

Any one ever tried this. or have any knowledge to share.

thanks.

I didn't try to use EF-S lenses on FF body via converter, however if you really want to use EF-S lenses on FF then consider lens modification, see this link.


I did that good few years ago, but to be honest it's not worth it.

I also used Sigma 10-20 f/3.5 (without any modification) on FF:

intresting shots there of the sigma on FF getting vingetting at 12mm so thats not too bad. I have the F4 version of the lense, not sure if it work am afraid to damage it testing.....

thanks for your info all the same....
