Operate M5 Without Lens?

[ Edited ]

I attempted to operate my M5 on a microscope, which means "without lens" as far as the camera knows. The camera was set to manual mode. The shutter would not activate either from the camera or from Canon Camera Connect on my iPad. In the case of the iPad I had a WiFi connection and could see the subject on the display. Ideas about what I may have done wrong? Thanks!

 

The workaround was to mount my 6D on the microscope. A bit heavier than the M5, but it worked just fine via the iPad.

I don't have an M5 or a microscope, but I do have the M3 and manual lenses.  Same difference.  What shooting modes did you use on the M5 and 6D.  You should use one of the creative modes.  I've always used the Manual mode with the M5 when I use a manual lens.

You need to change one of the Custom Functions Settings to allow the camera to release the shutter with no lens attached.

 

Press the Menu button.

 

Go to the Custom Functions tab in the menu.

 

Select "C.Fn II: Others."

 

Go to the third item, "Release shutter w/o lens".

 

Change that setting to "1: Enable".

Thank you, Larry! I knew it was in there somewhere.
