With the exception of a few Zeiss filters, all of my other filters are top of the line B+W filters. They, (Zeiss and B+W) offer protection for my lenses, but most importantly, none of them lessen image quality whatsoever.
Stay away from most other brands of filters if you can ! Tests have proven that they can alter and lessen image quality.
