Peteryunsie Posted March 11, 2023 Share Posted March 11, 2023 (edited) I have been having some AF issues recently that comes up randomly but not often. The camera sometimes struggles to focus on what seems to be a pretty easy subject to focus on and starts “focus breathing” (Not sure if this is the correct term) really fast and the camera is unable to focus on the subject. Sometimes, when shooting a person, the camera shows the square box over the subjects face to show it is recognizing a human and turns green but the subject isn’t in focus and the AF just starts breathing really fast again. I have tried on my different lenses and the issue still persists. In the video I believe I had my Tamron 28-75 lens on and from my googling the minimum focus distance is 7”, my camera was about 2 feet away from the subject. Has anyone had this issue before? This issue doesn’t come up that often but when it does it’s really annoying because it takes a while for me to focus on what I need to.

Advertisement Posted March 11, 2023 Posted March 11, 2023 Hi Peteryunsie, Take a look here Recently have been having some weird AF issues on my A7iii. I'm sure you'll find what you were looking for!
Pieter Posted March 12, 2023 Share Posted March 12, 2023 First one seems to be related to minimum focus distance. The minimum focus distance of 7" is only at 28mm focal length. At longer focal lengths, the minimum focus distance increases. You seem to be zoomed in and pretty close to the subject. Second one unclear. The subject moves a lot and face moves out of the frame, could give some struggles to the camera. Does the problem also occur on stationary subjects further away?

Yeah the first one wasn't at 28mm, don't remember what it was at, so I guess that could've been the issue. Second example: Could be, but just weird how it'd glow green to say it was in focus when it wasn't in focus, that night I was trying for a while for the camera to focus on any of my friends and it was struggling even if they weren't moving much. Can't remember if it happens on stationery objects or not. Link to post Share on other sites More sharing options...
