Canon 6D Mark ii, release shutter without lens option?

[chriswilloughby]

Hi, 

I want to use an old Nikon lens with my camera body for stop motion animation. 

I get err 1, about faulty communication between the body and the Nikon lens. 

I don't need communication between the lenses, and was planning to cover the Nikon sensors with electrical tape and set the camera body to 'release shutter without lens' in the custom function III tab in the the Canon 6D Mark ii. 

I can't find that exact option in my camera but perhaps the other options achieve the same thing, for example the AF OFF function or the AE hold? 

Any advice would be welcome, thankyou for your time.

Using an old manual lens on a modern DSLR is quite simple and safe providing you have the correct adaptor, it can be just a mechanical adaptor or one that has a special chip and electrical contacts.

In all cases you will only be able to use manual focus and aperture control, also it will only work in manual (green square) or AV modes. Auto mode will give you give you an error because it cannot communicate with the lens.

Using old AF lenses from another manufacturer is only practicable (in manual focus mode) if you are able to adjust the aperture on the lens itself, most AF lenses do not have this.
