Do you use a UV filter as protection?

Re: Lens Elements vs. UV filters

Absolutely true, a 14 element lens transmits less light than a 4 element given equal anti reflection coating,  The improvements in modern multi-layer coating internally and externally make our modern lenses (along with computer aided design) feasable.  This in no way invalidates point that adding two useless air-glass interfaces at best adds minimal degradation and at worst significant degradation.  Even in the days of Kodachrome II I never took a photo that I felt was improved by a UV filter.

Added note: Not every internal element necessarily adds two air-glass interfaces.  Cemented elements don't.
