Do UV filters work on digital?

In the comments in this picture the question is asked if the blue haze in the picture could be reduced and adds that in the old days filters would be used. Don't UV filters work on digital cameras? I've just bought my first digital camera (Fuji S5000) after using slides for 40 years and am very interested to know the answer to this.

I am not sure whether there is any difference but there shouldn't be, they should work the same on film and digital.

Anyway as i am sure you know you should always keep one on anyway for protection Smile

With regard to the picture i am sure a tweak in photoshop may help it.. will have a look when i get home (no photoshop at work :-p )

They still filter out the same wavelengths of light. This is nothing to do with the recording medium.

The digital sensor can only 'see' what is passed through to it, same as film.

Whether the sensor is responsive to UV wavelengths, and to what degree, is another matter, of course.

They certainly do work.

Thanks for that guys. I'll get out there and start shooting and keep the UV filter in place as has been the habit of many years.

And at the very least, you have a protected lens..

Be carefull with the UV filter on the S5000. It has a problem with focusing automatically with the UV filter in place. I work in a Photographic Retail store and have had personal experience with the S5000, it is a great camera but I have found that many images shot through a UV filter have focus issues. Just a tip hope it helps.

Thanks for that Ross. Does that apply to other filters do you know? I habitually use a Cokin polarized filter on my 35mm slr to improve skies and increase the saturation in colours by removing the shine off leaves, etc. I've only had the camera since Christmas and have had little chance since to do any serious work with it to test these things, but fore warned is fore armed.

I use a Hoya cir-polarizing filter with my EOS300D and it works brilliantly, I also have a range of cokin P series filters and they work fine with digital.

Thanks Gavin. I'm off to Spain very shortly so I'll give all my filters a go.

Yes...... a filter is still a filter no matter what lens it sits in front of.

if you have an AF lense, and want to use a PL filter, you pretty much need to get the circ PL filter, otherwise your camera will have difficulties focusing, of course, you could just focus manually...

I have used linear Polariser filters with most makes of cameras in AF mode & only the Canon cameras had any trouble focussing or getting the correct exposure!.

If anyone is considering getting one, try the linear version out first (if possible) as they are generally quite a lot less expensive.
