85mm F1.2 lens will only autofocus when in A+ mode, can any one help?

I’m using a Conon 5D Mk IV with a 85mm F1.2 prime lens. I find I can only get it to autofocus in A+ mode only, in all other modes I need to focus manually. Any suggestions?

Hi Ricky,

After further research I found this to be the solution: I had accidentally set my camera up to focus using the AF-ON button found at the back of the camera. To change back to shutter button focus I did: Menu - second last tab (which shows the camera icon); then go to the second tab within here and select "Custom controls". The first button within here says "Shutter butt. half-press" - select this and change it to "Metering and AF Start". This should change the camera back to shutter button half press focus. It worked.

Try resetting your camera settings.
