I purchased the 24mm f 1.4 from my LCS on Friday. Just a limited amount of time with it so far on my Sony A7R iii. When testing wide open, autofocus is fast and silent. Today, did some limited testing with the lens stopped down, f 5.6-16. In continuous AF, the green focus lock ball is solid. However, there is noticeable vibration when holding focus with the shutter button, and there is a bounce in the viewfinder. This is happening with plenty of light when stopped down beyond f 1.4. Focus point is set at medium spot in center of EVF. Not happening with my other lenses so does not appear to be a problem with the body. Also have upgraded last week to the latest camera firmware. Has anyone else noticed this behavior? Is the lens defective?
I have a 7 day return window from my LCS so easy to deal with. I have another lens from B&H arriving today (too late to stop the order after I purchased the first one) which I was going to return unopened, but now will be able to see if this second lens does not have the problem.
Any thoughts would be appreciated.
