You might also benefit from putting on a multi-coated filter to provide a bit more protection.
    Each their own... I go without a "protection" filter especially on wides where dew drops and dust on a dirty filter do their worst to degrade things.

    Filter are for collor-correction, polarizing, and B+W contrast augmentation... I stopped with the "skylights" in 1994.

    My 150mm planar has been rained on more than once... I am happier keeping lens caps on lenses when not in use rather than dealing with micro scratched skylight filters which always seemed to degrade fast...perhaps because I let them get so dirty.

    Anyway... I guess I'll just send this 16-35 in when and if I notice the blems are an issue. It is the most blemed up lens I have ever used... sad it was new 8 months ago.

    hi vpw

    like you i have made my income from using a camera since the same time period ...
    one thing i realize is that if you are the biggest critic of your own wdrk and while a "layman" may not find fault from bad /ugy coatings you might, and probably will ... i know i do with things i make when others mwy not notice &c

    I do use a digital device in my photographic pursuits when necessary.
    When someone rags on me for using film, I use a middle digit, upraised.

    Here's a question for you: Is there a difference between using a clear optical glass filter vs. a UV filter to protect your lens? In other words, if you don't need to be filtering UV because you're not shooting in the mountains somewhere, will a UV filter cause image degradation or color shifting at lower altitudes? I'll bet someone out there has done comparison testing or is this a question for Tiffen and/or B+W?

    The other thing that's problematic is when some people shoot with UV filters, they store their lenses with those filters in place. That creates a medium for growth of fungus, mold and mildew on the front element (both inside and out) because lack of air circulation promotes those kinds of growths. Those of course, can lead to scarring of the front element which brings us back to the age-old question that I believe came up before photography was actually invented: "How much mold, mildew, dirt, dust and debris is enough to adversely affect image quality?
    Take it slow ;>)

    The fact that you get income from your photography is unimportant. I'm a pro too...meaning, I expect and strive for professional results. What you mean is you're a commercial photographer I suppose. We all want and expect the best in our photography.

    Front element stuff often times has no effect on images, assuming there's a proper hood on the lens. I once had a Nikon 35 70 2.8 lens w/ deep and numerous scratches on the front and never saw any issues whatsoever. Some of the scratches were more like deep gouges, and I filled them in w/ black paint. Stuff on the rear can be an issue. More damning is haze or fungus. That's where you'll get flare and/or image degradation like a softening of the image.

    The only times I'll use a filter is for B&W, and that's all I shoot. Everything goes into a darkroom, so there's no post processing of issues in software. I use yellow, orange, that sort of thing. One of my best shots was ruined by flare from a UV filter, and it was a Leica filter w/ a more than adequate hood. Anytime you screw a piece of glass on the front of a lens you risk flare.

    Uncoated lenses can produce unique images and UV filters are an unnecessary air to glass surface that interfere with the purity of the image.
