Enabling the use of daylight-balanced film under tungsten-lit conditions, this 127mm 80A Color Conversion Filter from Tiffen is a cooling filter used to increase the color temperature from 3200K to 5500K. The blue color of the filter has a filter factor of 4x, requiring an additional 2 stops of exposure to achieve normal results.

The filter is constructed using Tiffen's ColorCore technology, which involves lamenting the filter material between two pieces of optical glass, grounding flat to a tolerance of 1/10,000th of an inch, and mounting within an aluminum alloy ring.

Q: 1. What part do I need to replace the rear lens cap?

Q: 3. Can it compatible with sony Carl ziees 55mm f1.8 ?

A: I am happy with the good sharpness of the 21mm adapter for the Sony 28mm 2.0 lens. The two components were very carefully matched to act as a single lens with lens elements of each half coming close to each other without glass touching glass. I have never tried putting the 21mm on another lens that it was not designed for. If you try it and the threads do match on the 55mm lens, you should take precautions to insure that the front 55mm lens element and rear 21mm adapter elements do not touch. Even if glass elements did not touch I would be surprised if the edge sharpness would be as sharp as it is on the 28mm Sony. Wishing you the best with your experiment!
