Wolfie, I have had some success using stacked lenses, my set up is as follows. Canon A1 with 69mm of extension tubes, a 135 f3.5 lense with a 100mm short mount lens reversed on it. The short mount lens is a Minolta and is designed for use with a bellows, it has no focussing mechanism and is about 40mm overall length. The lack of a focussing mechanism means that the lens to subject distance is increased. With this set up the lens to subject distance is approx 70mm and gives a magnification somewhere between 1.35 and 1.5 to 1. In my gallery there is a portrait of a wasp taken using this set up plus a small flashgun. The image is full frame no cropping.
