Thread: How to check for multi-coating

  1. #1

    Default Multi-coating?? Is it real as claimed?

    Here is an extract from kenrockwell website http://www.kenrockwell.com/nikon/nikortek.htm#afd

    A single-coated lens has reflections that are usually tinted magenta, blue or amber.
    A multicoated lens surface will take on many other colors. Most often you will see green, but every other color may also be seen, like deep red. The whole point of multicoating is to eliminate these reflections, so they may be very dim. If you see a myriad of colors reflected from the different elements you have a multicoated lens.

    Went to a shop today to buy a used Nikon L37c and took the opportunity to take a look at Hoya Pro 1 & B+W MRC UV Haze. Both Hoya Pro 1 & B+W MRC UV Haze have a magenta reflection from the florescent light only. While the Nikon L37c reflect mostly green and a bit of magenta just like the Nikon lenses.

    Does it means that the other 2 are not really multi-coated?

    Have anyone here tried to see what is the reflection colour from the Nikon NC?

    i don think it is accurate... my hoya hmc is green and by right hoya pro1 coating should be better than hmc (iirc pro1 is shmc coating)

    my hoya hmc is green. my hoya SUPER hmc gives a blackish-dullish-sometimes orangy reflection.

    my KEEP single coated gives a direct reflection of my light bulb (When placed under my light bulb) plus an additional bonus of purple fringing that's what u get for $10 filters
