In addition to the DSLRs, I have a Canon G5 point & shoot, that I generally like a lot for casting, parties, location scouting, etc, but as with its predecessor (to me), the G1, it will occaisionally refuse to focus after successfully focusing on the same type image for several shots. In typical "only me" fashion, I had a model come see me the other day who wants to get into Playboy, so I had her throw on a bikini to do my usual sequence of casting shots. I set her up in front of a plain tan colored wall, and we get about 20 shots - headshots, 3/4, front, back - with the G5 and its built-in flash (these are only for MY eyes, my files, just need something to reference her with). The focus locks in, flash goes off, pictures are totally sharp. Then she takes off her top, and after the second frame of topless, the camera refused to focus. I could watch it rack right through the focus point, and fire as soon as she was unrecognizable, 10 times in a row. I hadn't changed anything, and I did try using manual focus, but I don't really know how that works on that camera, so I said screw it and told her to get dressed. After she did, I wanted to try a couple shots in her sweater, and of course they were perfectly sharp. Now someone tell me how I explain that
to a Canon tech.
