Canon CN-E 35mm T1.5

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.

Centering is a combo of front group and group 2. Once the front group is out remove plastic cover from group 2 to expose 3x phillips holding group into follower housing. Once screws are loose you can eyeball adjust centering here or reload front group and have access to the side of group 2 through the additional through holes on main body next to the follower through holes to adjust centering on the projector or vertical collimator. On the projector if the lens is flaring down push group 2 up to correct for it. .
