I have a L series on the way (will get here tomm morning). When it arrives should I add a UV filter to it?

The only reason I wouldn't is if the filter screws up the optics.

What do you guys think?

Get the best filter you can afford...don't put a $5 piece of glass in front of a $1500 lens...

I wouldn't but I think everyone should until they are really comfortable with their equipment.

depends if you scrath your lens (and accidents can/do happen) if you want to replace whole lens or just the filter.... i agree with doctornick..get best one you can

Different theories on this, pick one you like. I am not of the filter fanatics crowd. Why? Optics, cost, it can trap dirt as the filter is not sealed in any way. Even a good filter is going to degrade the image (yo may not be able to tell is all) - is is another piece of glass for the light to pass through.

they why is for protection - from what? a errant banging of the glass on something? lens caps, hoods. common sense. also, a front element can take a good whack and not have it effect the image one whit. resale value is something else of course.

I own a fair amount of L glass, and I do not have filters for any of them when I shoot. I've yet to scratch a lens. I get some dust, but I brush it off with a lenspen or a microfiber cloth

I do however use cheap cheap filters as screw-on lens caps. For whatever reason, those 77mm lens caps will sometimes come off in transit when I'm flying. By using a cheap filter, I know I'm protecting the lens from scratches during transit, and it keeps dust off in between uses.

I will say this: if you plan to buy filters, expect to pay a lot, because you'll want the best filters.

I agree with Max. Take a pro shooter, like Max. His gear probably gets treated worse than 99% of our gear will ever get treated in its entire existance. From what I understand, it's harder to scratch the front element of a lens than you think. Heck, I don't even use my little lens cloth anymore. If I see some dust, my shirt goes over my hand and it wipes in a nice circular fashion -- haven't scratched a lens yet.

I will say, however, that if you're on the beach, you definately will want a UV filter. Salty ocean spray is horrible. That being said, there will be other times when I'll throw one on -- like if I'm pretty certain some nasty stuff may fly in my direction...but 90% of the time, I don't think it helps, and can actually hurt.

The front element can take a decent impact...especially with the lens hood on properly. I've heard of cheap UV filters getting broken and the glass from that embedding into the glass of the lens -- whether or not the lens would have been OK without the UV I don't know.

The only filter I would buy is the polarizer. I have it for my 24-70 and wouldn't have it any other way.

If you haven't already, read this article over at Luminous Landscape.

I put filters on all of my lenses, any time I think they might be in an environment when they might get damaged. (I.e., deserts, wet/salty environments, concerts, near small children/animals)

Or I put filters on when the filter is going to have an effect on the picture.

Otherwise, nothing on the lenses other than a lens hood.
