Lens hoods can become loose over time, leading to annoying rattling sounds or problematic vignetting if the hood rotates into your shots. Instead of buying a replacement hood, you can apply a quick fix using a little tape or glue. Simply cover the threads with a few layers of tape or a few dabs of non-permanent glue (be sure to wait until it dries). The extra material around the threads should help the lens hood to secure much more tightly to your lens.
If you’re the proud owner of a Sony NEX-5N but have been pulling out your hair due to strange clicking noises ruining your videos, here’s some good news: it’s not just your camera. Frustrated camera owners have taken to the Internet to complain about the faint clicking noise that can be heard from inside the camera when moving it around, a problem that was found in every NEX-5N that Engadget tested. 1080/60p video recording is one of the highly touted features on the camera, so Sony could be in for quite a PR nightmare if there isn’t a simple fix for this widespread problem. If you’ve been considering the NEX-5N, hold off until this is resolved.
