If they do, it might be possible to correct a lens to a more neutral look, making coatings less of an issue.

p>Having said that, I have a couple of lenses where the front element is so large and so close to the filter rim that it would regularly get thumbprinted or scuffed by the lenscap if not for the filter. or less, the grand total transmission loss for any lens, even complex lenses with many element groups, will remain very low (i. Please Contact us at any time if you have any questions, we will give you the most satisfactory solution within 24 hours. As such, transmission is not ideal, and up to several percent of incident light can be lost for any given wavelength, usually resulting in 1-2% total loss in transmission PER COATED ELEMENT/GROUP.I've experienced first hand what horrible quality can result from using such filters, and over the course of 4 years, using about 10 different lenses all the time i've never once scratched a lens. I assume Lens rentals clean 100's or lenses and cameras every day and many threads above agree with what Lensrentals say. zooms, all with nano coating, Nikon published an interview with two of their engineers about nano coating:
