Canon EF -28-135mm IS USM or Canon EF-s 18-135mm IS STM Lens

mr.mike · Dec 13, 2023

Hi,
I have a Canon EF-28-135mm IS USM lens and a Canon EF-s 18-135mm IS STM lens. The EF is on my EOS 5D and the EF-s is on my EOS 50D. Just wondering if I need both lenses? Looking forward to your responses.................

You're the only one qualified to answer that!

Ok just a thought, you do know that if you put the EFS on the full frame you risk smashing the mirror
EF on crop body no probs but not EFS on FF
Have you taken the 1.6 crop factor into your thoughts.
I would stick with the EF lens knowing that I could use it on both bodies
