For optimal light transmission and reflection control, lenses need Anti-Reflective (AR) coatings. The more there are, the better the performance. Do you know the difference between all the levels of lens coatings though? Here they are:
Coated: Only 1 side of 1 lens must have a single AR coating to qualify.
Fully coated: Both sides of all lenses must have at least one layer of AR coating.
Multi-coated: Only 1 side of 1 lens must have at least a multiple layer of AR coating and both sides of all other lenses must have at least a single AR coating.
Fully Multi-Coated: All sides of all lenses must have at least twice two layers of AR coating.
If you want the best in optical performance, fully multi-coated lenses are a must-have, and it’s why all Prime, Nitro and Forge optics have them.
Look for fully multi-coated the next time you’re looking at the specifications of optics.
