During my early days, ie, in the early 70s', I only had fixed lens, ie, 50mm or 105mm or 200mm. I was really itching for a zoom lens. So, I remember buying a zoom lens from Tamron. I like the result when I fixed it to my German made Rollieflex camera. But at the end, I still go back to my "prime" lens because I find it impractical to change lens in the field, ie, on duty.
Ok, today, my plan is not talking about the past but to talk about the "nano coated" modern lens I have from Nikon.
I read from their web site about this new technology:
"Nano Crystal Coat is an antireflective coating that virtually eliminates internal lens element reflections across a wide range of wavelengths, and is particularly effective in reducing ghost and flare peculiar to ultra-wide-angle lenses. Nano Crystal Coat employs multiple layers of Nikon’s extra-low refractive index coating, which features ultra-fine crystallized particles of nanometer size."
So, I brought my camera out for field test on Saturday and pointed it into the bright afternoon sun.
Camera: Nikon D3 with a AF-S NIKKOR 24-70mm f/2.8G ED lens. Flash was not used.
The huge sun was right at the corner, and true to its claim, I could hardly see any ghost and flare with this type of shots. However, there are three "spots" clearly visible next to the sun.
In the good old days, we had multi layered coating and we could never take any decent photos like the one above.
So, do you think it is worth the money for the new high tech lens? Check out the price and you may faint! Perhaps, the price will drop when it is getting more competition.
Warning: Avoid pointing your compact camera to the sun for too long or you may damage your sensor. If you are using SLR, you may damage your retina. So be careful!
