Anamorphic lens for 5d mii
Posted 14 December 2010 - 03:42 PM
I am looking for a anamorphic lens for my canon 5d mark ii.
Does anybody know what adapters or what I should look into to

None of the readily-available types are very cheap or very sharp. The Panasonic LA-7200 was designed for a standard definition DV video camera and has optical performance problems that are visible even in that format. They have been used on a 5D but the vastly larger sensor can make coverage a problem, especially with wide (or even not so wide) lenses.

A more popular option is a 1.3 or 1.5x anamorphic adapter like Phil mentioned. Iscoramas are known to be the best quality anamorphic adapters, though with prices that have shot through the roof in the past year due to renewed demand.
- Extremely sharp, high quality glass.
- Rear threads allow you to screw the adapter right on to the filter threads of your taking lens without any sort of clamp or mount.
- They come in 3 sizes, the smallest being the Isco 36, Isco 42, and the largest, the Isco 54.
- 1.5x squeeze produces a 2.55:1 aspect ratio. Very close to cinemascope 2.35:1.
- The Isco 36, the only adapter of the family without multicoating on the lens, produces the strongest flares.
- Vignetting is a big issue with anamorphic adapters. Don't plan on shooting wider than 50mm with your 5d on the largest aperture Isco available, the Isco 54.
- Rack focusing is almost impossible with any anamorphic adapter, though the Iscoramas manage better than others due to its focusing front element, which unlike other adapters, does not require focusing of both the taking lens and the adapter at the same time. Close focus filters, or diopters, are required to focus closer than the minimum focusing distance of 8 feet.
- Chromatic aberration is an issue with the larger adapters at larger apertures. f2.8 and above seems fine.
Isco's aren't cheap, often going on ebay for $1500 and up. Popular lower cost alternatives include Kowa and Sankor adapters which are reasonably sharp with strong flares and 2x squeeze ratios. I would stay away from the Panasonic adapter as users have reported it to be excessively soft below f8.
