Interesting reading Craig... My last attempt with an anamorphic lens, a ISCO III 1.33x, made me finally decide on overshooting being the more preferred method. The chromatic aberration, light bleed / reduced contrast, reduced sharpness and only what I was able to measure out as an 18% increase in light output made that conclusion quite clear to me. I do get, however, some installs simply needs a lens to get a sufficient throw, and 18% is indeed a nice boost too, so I completely understand that others might come to another conclusion than me... However, this vertical compression lens seems to be producing quite a significant boost, 30-40% is kinda amazing and in these HDR times more important than ever. I mean, are you not seeing any of the "normal" artefacts introduced by this additional optical element mentioned above? Is the overall sharpness seemingly better? Your observations had me a bit intrigued, might even want to order one and test it out for myself....
