Z3321 Posted July 1, 2015 Share Posted July 1, 2015 Hello, I have an anamorphic with a 100mm front element. The whole thing is being converted, but when the elements are too close together, the squeeze factor changes. My question is are there any affordable diopters that are 100mm or bigger?

Russell Anway Posted July 2, 2015 Share Posted July 2, 2015 Check out the diopter thread my man! It's pretty much the most comprehensive discussion of large diopters for anamorphic lenses on the whole interwebs. Only a few links above this one! 100mm is pretty big though, so "affordable" is going to be tough! Quote Link to comment Share on other sites More sharing options...
richg101 Posted July 3, 2015 Share Posted July 3, 2015 unfortunately using a diopter will do the same thing as setting your lens to a closer focusing distance. the closer you focus, the less the anamorphic squeeze. a 1.5x anamorph will be 1.5x at inf, and around 1.3x at 1m. with or without a diopter, the squeeze ratio changes according to how far you deviate from infinity.A 2x anamorph will be 2x at infinity and around 1.7x at 1m. It's an attribute of all anamorphic systems which use a spherical focus section up front. Never the less unfortunately the terms '100mm front element', 'anamorphic lens' and 'affordable diopter' will never sit well together in the same sentence.
