I have a bunch of old nikon lenses and a lens coupler and was going to try stacking them in a trial and error fashion. Any thought on what stack might work best or is there something online that already gets into this issue? Generalities? Use matched lenses or any combo, faster lens in the back or front? longer lens in the back or front? I was planning to start the stack with the 55 f1.2 on the camera stopped down to 1.4/1.8 and add other lenses from there.. Has anyone used a zoom for the reversed lens and use the zoom for focusing? Seems like it may be the perfect solution for a wider range of focus if it works at all. Lense possibles (all 52mm filter ring, manual lenses): 200mm f4 200mm f4 micro 135mm f2.8 105mm f4 85mm f2.8 55mm f3.5 micro (6 or 7 of these) 55mm f1.2 50mm f1.8 50mm f1.4 (several) 35mm f2.8 28mm f3.5 24mm f2.8 and a few short zooms and others I'm forgetting at the moment.
