It gives better working distance. Focal distance is irrelevant when dealing with final magnification size (use whatever focal length you have with some kind of technique, extension, close-up lenses, etc to achieve a specific magnification). Actually a 50 reversed on a 105 is not my first choice. What works really well for me is a 100/4 SMC Bellows lens reversed on a 200/4 SMC-M with a little bit of extension to avoid vignetting when stopped down. You get 2x magnification and greater working distance so you don't scare away the little bugs. http://pug.komkon.org/02jul/fly01a.html One advantage to reversing a short lens on a long lens is that you still get open-aperture metering (the 100 bellows is set wide open and acts basically as a high quality close-up lens. The 200 doesn't lose any functionality). With a reverse-mounted lens directly on the camera body you lose open aperture metering. One cool thing about the Bellows A is that you can reverse the whole front stanchion which gives you great functionality when using the LX and double cable release because the aperture is open until you push the cable release which first stops down the lens and gives the LX time to meter and then the shutter is relesed and the LX works its magic. It works great with TTL flash too! Christian
