Canon R5 Manual lens operation w/ R5

[SF_Mole]

One day shooting at the beach I couldn't get my Laowa 12mm fisheye lens to operate on the camera. It's a manual aperture lens; no auto anything. Turns out that to use such lenses you have to change a menu item to allow the camera to shoot w/o a lens on. Huh? Why would you ever want to do that you may ask. I did. But I digress. The menu item is in the Custom Functions menu (6th menu), tab 4, "Release shutter w/o lens". Here's a quick vid tute: https://www.youtube.com/watch?v=zcRSrbyyynE

I use a few takumars as well and needed this option enabled. Agree it's strange but I guess we have to roll with it.

Yeah, had to do the same thing so as to be able to use my Helios and Volna lenses. Didn't have to do that with my 5dmk4.

In Digiscoping, with camera attached to a spotting scope with a special adapter, the “shoot without lens on” is necessary in order to “see” through the scope. It’s just that you aren’t using a lens that the camera recognizes.
