My canon 15mm lens won't take pics in freefall when it's on any XS camera, but it will work with all other cameras. Anybody ever hear of this or had this problem?
I had a Canon 15mm lens once that stopped taking pics at certain times, and it was hard to determine what was causing it. I finally determined that it was related to the aperture (I think it was at wide aperture settings). I believe the blades were bent or sticking. I temporarily "solved" the problem by shooting at higher ISO (I think) to keep the aperture smaller until I could get a replacement. Note: This was a couple of years ago, and it may have been at smaller apertures, but the problem is probably the same, just the solution was reversed, i.e., lower ISO.
