Do I need a UV Multi-Coated Glass Filter for a Nikon D80 digital SLR ?

I have heared that for digital SLR cameras, it is worthless to buy UV filters. Is that true ? I am looking in buying a Hoya 72mm Multi-Coated Glass Filter CLEAR, but also have the option to buy the same WITH UV filter for $20 more. So i guess my question is... are CCD sensors from Digital Camera sensitive to UV ? Thanks !

UV filters tend to clear up hazy horizons in landscape photography. A new modern filter will not hamper the CCD in any way. Both my digital fujis have them with no problems.

Only problem for SLR was that I needed a filter for every lens - more expense! So this time I didn't worry about it for my D50

You have a D80???? I am jealous, they aren't even released here in Australia yet! I want one!

Only for the Nikon D75

Digital cameras are supposed to be less sensitive to UV than film. You would still need a filter, a clear one to protect the lens.
ask at a photo lab, usually photos taken by regular amateur people with digital cameras have less haze.

The reason to have that filter on your camera is to protect the lens from being scratched. Scratched glass filter? Toss it in the trash and get another one. Scratched lens? Well, that majorly sucks ***. The better the lens, in general, the less likely it is repairable to an acceptable standard. If you get the UV lens, you likely will find many situations where you don't want to use it. Meaning, you will be tempted to take it off and risk something you very much might mind losing.

Use a clear filter. If you get too much UV light, just adjust your white balance.

Camera shops love to sell you UV filters. They really are not worth buying. They claim it is to protect your lens, but in fact, with proper care you do not need them and they add one more layer of glass for the light to have to pass through to make your picture.

There are filters that are worth buying, but a UV is not one of them. The one that I would say is a needed filter is a circular polarizing filter. (not the linear unless you do not have auto focus as the linears work fine on manual focus, but mess up on auto focus cameras)
UV filters are not necessary to protect your sensor.

Sensors are less sensitive to UV than film, but not impervious.
Then again, ordinary glass elements, in particular elements with multi-coating layers, will do a great job of keeping most UV from ever reaching the sensor. So really, getting a UV filter is a little overkill.
On the other hand... if you don't mind a little overkill... I can highly recommend a B+W UV MRC filter for protection. I have one on my $1200 Nikon 17-55mm.

You must have a filter (UV or 1A...) on a lens. The reason s simple. You can be as careful as you want but if by chance the lens brushes against anything it s much much cheaper to replace the filter than the objective optic of your lens.

Clear UV filter on digital is good only as extra protection for your lens. Will keep away from the main lens the dust or some fingerprints. Is much easier to clean that UV filter than the main lens.
