I use Canon lenses, big, white, conspicuous lenses when I'm using a telephoto. The color, or conspicuousness of a lens probably doesn't matter very much for most animal subjects, as most animals are probably aware of YOU regardless of the color or camouflag of your gear. There might be exceptions -- certainly in Kenya when someone pulls out a big telephoto close to a nearby bird the chances of the bird fleeing are a bit greater when the lens flashes white (or black, for that matter, with Nikon) than they generally do with a grab camouflaged lens.
To me, the advantage of using a product like LensCoat lies in two areas. One, the lenses are indeed camouflaged, and in the field these lenses are less conspicuous to other people. In places like Yellowstone where one photographer is likely to draw other photographers like a magnet, having gear that is inconspicuous lowers that possibility. For that reason, I generally wear drab or camouflage clothing when afield, not because I'm trying to hide from my wildlife subjects but to draw less attention to myself from other photographers or curious on-lookers. I can't tell you how often good shooting opportunities have been ruined when people have approached me or the subject I was shooting without regard for the effect they might have on the subject. I may have spent hours slowly moving into a position when someone, seeing me, barges in and walks briskly up to a position that may have taken considerable time and effort on my part to accomplish. The result -- the subject often moves away. Having protective, camouflaged lens and tripod leg covers lessens my conspicuousness and the chances of that happening.
Secondly, the LensCoat is a neoprene cover that acts as both padding and insulation. While the LensCoats aren't designed or intended to protect your lenses from damaging bangs, the neoprene does, nonetheless, offer a bit of protection in that way. On cold days, the cover also acts as an insulator, especially on tripod legs that can drain warmth from cold fingers.
Recently I received an email from Scott Elowitz, the owner/designer of LensCoats, alerting me to some new products, which included camera and flash neoprene covers. If you travel as I often do, placing gear in large roll-on bags or in a backpack without individual dividers, these covers are very useful in providing protection and padding to your gear.
The lens and tripod leg coats come in several different patterns, including plain black or white covers, so check out the website, www.LensCoat.com, for the choices, and for the exact LensCoat that is designed for your particular lens.
