[QUOTE="WayneF, post: 117604, member: 12496"] You will have a problem because I think your 50 mm lens is a G lens, without any aperture ring. So if you reverse it, you break connection with the camera, which could have otherwise set the aperture. You need an older lens, with an adjustable aperture ring. Your 50mm lens normally focuses to 1.5 feet, and if steady on a tripod, then you can crop to use only the center, which greatly enlarges the remaining, esp for video monitor purposes. Its frame is 4928 x 3264 pixels, and cropped to 492x326 pixels is 10x enlargement (compared to printing). Probably is adequate for all but the tiniest things? A reversing ring can give high magnification, more with a wider lens, but a lot for non-macro subjects with a 50mm. The idea is normally, there are many feet of distance in front of a lens, and only a inch or two behind it. So if you reverse it, now you have more distance behind than in front, so it may focus up really close.
