When I used a film-based SLR, I always had a UV filter fitted, to
protect the lens *and* to prevent UV light from compromising picture
quality. Is such (UV) protection necessary for the digital camera I plan
to buy soon (Panasonic FZ3 or K-M Dimage Z3), or are CCDs immune to that
type of problem?

UV is apparently much less of an issue with digital than it was with
film, although I have had a couple of digital pics from my C-5060
ruined by what looks suspiciously like UV fog.... I think I'm just
being paranoid, though. I keep a UV filter on the camera most of the
time, as much for cheap protection from scratches as anything else -
it's color neutral (unlike skylight filters), doesn't affect exposure,
and they're cheap like borscht.....

I'd suggest getting a good lens hood instead.

With modern films and lenses, neither your film camera nor your digital
camera needs a UV-blocking filter for picture quality. If you want to
protect the lens, make sure your filter is multi-coated; otherwise you're
adding a source of unwanted reflections.

CCDs are less sensitive to UV than (most) film. Whatever you buy, make
sure it's multi-coated on BOTH sides of the filter. Many say they are
pointless and just add flare so if you think you need one, you want to
try and reduce that risk.

I believe that the chips are optimized to ignore light in the UV range.
I've never heard of anyone using a UV filter on a digital camera, and one
would think that every filter manufacturer would be pushing them on us if
they could.

Film, unlike our eyes, does respond to UV light. Even though we can't see
it, film does--and it has been known to fog film with a bluish cast. I use
UV filters on all of my lenses for my SLR. I can't recall anyone ever
raising the question regarding digital, though.

I use one on all of my lenses regardless of film or digital. I'd
rather pay 100 bucks to get rid of a scratch than buy a new
lense.

After I've seen how much worse the stray light situation becomes
with an extra filter, I no longer use any filter for lens
protection.

A simple test is to pull out the camera at night and look at
something that has a few bright lights. Then, while looking
through the TTL viewfinder, hold a filter in front of the lens
and watch several new reflections appear that are simply not
there without the filter.

Unless you are very careless with your camera, you don't need a
protective filter.

In situations with lots of sunlight, instead of a UV filter use
a polarizing filter, if you can put up with the extra work of
rotating it into the optimal position.

A coated filter, an uncoated filter, a multi-coated filter, a solid
glass filter, a sandwiched filter?

Hi HAns!

I was always told to use a Skylight. Is this wrong?

A skylight filter is a warming filter so while it won't effect the
exposure (a Heliopan KR i.5 skylight filter has a filter factor of 1.1)
it will add some red to the scene.

A UV filter has the same effect on exposure but it will not add red.

Takes your choice. Both protect your lens from dust, moisture, sand,
fingerprints, smoke, etc. and both will cut UV.

I actually prefer skylight filters (1A or 1B, Nikon L1Bc). They
demonstrably increase the sharpness of some of my long telephoto lenses, and
they warm the colors slightly.

Hi Bob!
Now I understand why I always have to correct for red, especially with
photos taken with a flash (interior)
Thanks,
Marcel

I use UV filters to protect my lens but I must admit it is a bit of a dilema
as what you end up doing is buying a super lens then putting what (probably)
is an inferior peice of glass in front of it!! I wonder if in fact you're
better buying a cheaper lens and not using a filter.

Out of interest, what brand of filters does everybody use? I use Hoya but
of there are better I'd change in a heartbeat.

Hoya makes very good as well as very average filters so, without knowing
which Hoya you have, your statement doesn't tell us very much.

The best filters are the German ones from Heliopan and the other
supplier in Bad Kreuznach.

I use mostly Heliopan but have a couple of B+Ws. Heliopans seem just
as good optically and as well built and cost a little less. I seriously
doubt you could see any difference by adding a quality multicoated filter.
I hike around and trudge through brush, etc so it's a necessary insurance
policy for me.

B+W is the only filter I use on all my lenses.

Where are these sold, please? I made a research on Internet but couldn't
find a place. I'm from Canada. Some of these places do not ship here.
Thanks for any info.

I don't know if B+W is better, but they have a good reputation.

Hoya and Nikon, multicoated. I don't think they are inferior pieces of
glass. But I avoid the cheaper ones.

Bob,

whatever you want to test. Even the best filters will add very
visible reflections in a night shot.

Marcel,

this is certainly wrong, unless you specifically want the color
effect of a skylight filter.

My advice was to use no filter at all, unless you have a very
good, overriding reason.

In other words you have personally tested them all and are not going to
answer the original question?

Angela,

no, you're better off buying a super lens and not putting any
filters on it unless you really need the filtering. Then make
sure not to bump the lens against anything or put a hood on it.
That's the only professional way. 🙂-)
