. I've posted photos both 'with' and 'without' this screw-on lens, all taken about 12 inches from the subject. Experiment with them and your separate camera to see what results you can get at different distances, focusing systems, etc. But at this price, it's definitely worth an experiment. I don't think you can put a standard plastic lens cap on it. However, if you leave it, take a neoprene "hood". ".
