Image Circle... which most long lenses have .. the longer the lens, the bigger ( in general) the image circle. Lens registration.. in this case, how far from the focal plane is the back of the lens.... I would think the R registration is much shorter than the S2. For the long lenses, you can usually machine off the "extra" to make it work or ad on something if required. For a 50mm or so, I doubt it. OTOH, I have no info on the actual focal plane to lens plane distance on the S2...... Frank Filippone Red735i at earthlink.net I know for sure that the 50/2R has a rather large image circle - it covers 55mm (wide) of the XPan frame. I think the wide angle zoom 21-35mm also has a very large image circle as well.
