Hello,

 

I have myself a a 77ii and just got my 400mm 5.6 macro from sigma.
They said it should autofocus whitout problem but it doesnt.

I think the video would describe the video and show how strange it is.

Can someone tell me what is wrong whit my settings/the lens or camera.

Because it can focus but not whitout focusrestriction which is build in in the

camera.

p.s. i set the af motor to slow so if somethings broke it wont brake it as soon.

The problem is when i dont use the in body focuslimiter it focusses always closer and if the lens is at minimum focussing distance it wont go back to infinety but the lens makes that weird sound. The weird part is when i use the lens focus limiter it happens already at 3.5m that the lens get stuck when i use the in body limiter it goes to around 2,5 meter whitout problem and then it will go back to infinety.
