Canon CN-E 50mm T1.3
Summary
The Canon CN-E line of primes lenses was first introduced as part of their Cinema EOS product line in 2012, initially with the 14mm, 24mm, 50mm, 85mm, and 135mm with the 20mm and 35mm being added later on. The CN-E primes are fixed focal length lenses that inherit their optical design from the popular L series still-photo prime lenses from Canon. The CN-E primes are only available natively in Canon EF mount but can be converted by Duclos Lenses in Los Angeles, CA.
