hi, thamnks for the answers, I also had not heard of mumping until recently whilst reading panavisions literature on the G-series, where on page two it specifically says "the lenses utilize panavisions patented anti-mumping technology" sounds like something new to me not something that was eradicated in the 1960's.it goes on to say there is no "hump" in the gear set, so the lenses maintain their cylindrical profile , any offers on how this works.

Hi, Can anybody explain the mumping of anamorphic lenses how it actually occurs on a elemental level, and how one avoids it.How well does the anti mumping in the newer g series lenses work. thanks, jason West
