so today I was takin macros of my fish.\ i first used my sigma 150 (both normal and AI servo mode) and then I put on my mpe-65 and took manual macro shots. I then shut off everything for a while, came back not too later to take pictures of my wife using the 35L, while taking pictures of her I attempted to take some pictures of my aquarium , first in normal then ai servo, then suddenly the focus went dead.
It keeps blinking (the dot), it understands if ive focused because I can manually focus on something and then when i hit focus, the dot then turns solid. Or I can hold the focus button and then turn the focus ring on the lens till it "captures focus"but it will not AF.
I have turned off the camera, removed the lens, cleaned the contacts (on lens) with microfibre cloth, made sure it was in AF not manual mode and tried again. Nothing! I tried the sigma 150 again and the 135L, both work.
