I've really been debating with myself whether a "Protective Lens" is necessary, there are options, I can go for a UV and an MC Protector.What exactly does it do other than protect the lens? UV is supposed enhance images in some way methink. Also some fellow told me it "protects" the sensor...hold on....can sunlight (direct shooting at the sun) even damage a sensor???
Anyways just looking for adivce.I'm with a Sony R1 (and treat it better than my cat) and use a lens hood on it to make sure i don't bump the lens into anything and ruin it.Protector sounds nice but don't want to buy it un-necessarily.Thinking about it any accessory is great, but is it really worth it? (About 45$ or so)

UV filters don't help with digital photography if i'm not wrong. They did with film because of the blueish tint introduced by UV light or something. Anyway, I've equipped most of my lens with UV filters for protection because I'd rather have a damaged S$95 filter than a damaged S$2000 lens... But then again, I shoot 2 of my lenses without filters. One because of image quality issues (I only have a non-coated filter for the huge 86mm thread size. coated ones would be S$200+) and the other because it already has a protective lens element built in. I always use my lenses with hoods and have never had any problems with scratches or anything.

So i guess it's fine to leave out the protective filter if you religiously use a hood. But if you really want to get one, get a good quality multi-coated one otherwise you'll find yourself faced with more flare issues than before.

There's always a big dispute about this one. A lot of people believe that the UV filters only degrade the image quality and do little to protect a lens when it's dropped. Personally, I'm in the other camp. I've got UV filters fitted on all my lenses. A good filter has negligible impact on image quality - you shouldn't even notice it.

On my point and shoots I don't use any filters, and the lens coating has become scratched in places (there's a 0.5mm by 0.5mm spot where the coating has come off on my FZ20). I'd never be brave enough to not use a UV filter on my L glass - especially since they are lent out so often (*ahem* Jide)!

IMHO, it's worth spending about 10% of the price of a lens on a filter for it - for SLR lenses. On point and shoots I'm not so sure if a filter is worth it. Such cameras get replaced fairly often anyway.

Thanks guys, I think I'll go for it. It's not a UV filter, just a protective lens.

There's not much difference between a UV filter and a protective lens - so you might as well go for the UV filter if the price isn't too different. But most importantly, make sure it's multi-coated. Otherwise you'll have problems with lens flare. If you're wondering about brands, B+W is tops (but can be rather expensive).

Filter shadow? I assume you are talking about vignetting. That depends on the thickness of the filter and how wide the lens is. Generally, anything above 24mm doesn't require any ultra thin filters. But for those who really need one, Hoya does a Pro1 range that is 3mm instead of 5mm.

A UV filter won't degrade a lens when used on film to any noticable extent (if it is a good quality filter). However it will certainly degrade the quality if you are using a digital sensor. For resons to long to go into here (but those of you with a understanding of the physics of light will understand) digital sensors are much more suspetable to all the problems caused by difraction. Those of us using quality sensors in the larger sizes (ie on Canon 1 series cameras) will already be experiencing some of the problems of difraction on the outer ares of the lenses. The manufacturers get round this by using small sensors but this gives a correspoding increase in noise.
The best quality lens will only be harmed by adding a piece of glass that wasn't intended to be there to it, so don't. use a lens cap to protect your lens. If you must also use a filter take it off before you shoot.
Try a comparison with the filter on and off and take a close look at what happens. if you can't tell the difference I would be very suprised.
