Kinefinity EF II Mounting Adapter w/ e-ND

Kinefinity EF II Mounting Adapter w/ e-ND

Electronic ND (Electronic Neutral Density Filter) is based on modern liquid crystal materials and optics controlled electronically, which is completely unlike conventional technology such as a rotating filter wheel or polarising ND Filters. The e-ND on TERRA brings sharp images with color fidelity but without any drawbacks of traditional variable ND.

Compared to traditional optical glasses, electronic ND (Electronic Neutral Filter) gains a lot of advantages: eliminating the ND filters at the front of lenses; adjust the exposure seamlessly over a very wide range; keep TERRA and your gear into a more compact and lightweight set when ND needed. The e-ND developed by Kinefinity also is available on PL Type.

So far, there are three types of EF mounting adapters for different scenarioes:

Regular EF mounting adapter without any glass or filters: Clear, 0 stop;
New EF mounting adapter with e-ND in this page: 0.6~3.0, 2~10 stops;
EF mounting adapter with KineEnhancer: 0.72 focal reducer, extra 1 stop for max iris.
