Ok it was bound to have happened sooner or later, but camera and lens finally got knocked over while on a tripod. Its the first time since Ive owned the Canon 28 80 2.8L that it has had any kind of a hard impact, and owned it over 15 years. The impact wasn't that hard either, but I just cringed when I saw it in the floor.I think some testing is called for. Many moons ago I took a fall while walking across uneven ground holding my Nikon D200 and 18-70mm lens. There was no obvious damage to either camera or lens, and both appeared to work.
Question How closely are these things calibrated? No broken glass. No nicks that I can see right away. No lens cover on it when it fell, but did have a UV filter on it. Could this have knocked something out of calibration so that it needs to get checked? Mainly worried about the auto focus. Is it possible for the electronics to think its in focus at a given point, when it isn't? Never really understood how much of the auto focus system is in the body, and how much is in the lens. The body is a Canon 50D which is at the end of its life cycle or past it anyway. The lens is what I hoped would last the rest of my photographic days.
