Canon R5 mark II & R6 mark I do not have "Release shutter without lens option"

travelchanda — Thu, 29 May 2025 13:41:38 GMT

I am attempting to use my Laowa 15mm f/4 wide angle 1:1 macro lens with the Canon Mount Adapter EF-EOS R adapter. On previous cameras I have only had to set "Release Shutter without lens" but I cannot find this option anywhere in either the Canon R5 or R6's menus. When looking at Canon's compatibility matrix it appears that this lens should work, but maybe I am missing something. Every search I have made of the forums or Google search it appears that I should have an option to "Release Shutter without lens". I am shooting in Manual mode.

Anyone have a fix or an idea of what I am doing incorrectly?

Thanks!

I have it on my R6. I use FD lenses. Don't have the camera here right now but I find it at page 772 and 795 for R6.

For the EOS R6 the enter is on the brown custom function menu, page 4.

This is the screen where you will find the option to release shutter without lens on the EOS R5 Mark II, it's the 4th line down.

Thank you to everyone who responded! I was able to find the option that I swear I looked for on multiple occasions…. Only excuse I have is that I am in a photo workshop and very sleep deprived.
