UV and Polarization Filter Discussion
I have read some debate
concerning the use of UV filters. Their main use in my view is
one of protection. It your lens hits something your UV filter
will get scratched or possibly break and your lens will be fine.
Just unscrew the UV filter and purchase a new one. I think this
is a big advantage when you are working with lenses that cost more than
$1000. Others claim their is no point in purchasing an expensive
lens made from the finest glass around, and then add another layer of
glass on top that is of lower quality. Why purchase such a fine
lens and decrease it's abilities by adding more glass, and probably
lower grade glass. Personally, I disagree. I can't see any
difference in the quality of a photo with or without my UV
filter. The recommendation by those who are against the idea of
purchasing UV filters for protection, is to always use your lens
hood. The lens hood sticks out a considerable distance from the
front of the lens, is less expensive, will not add more glass over your
lens, and adds even more protection. I would have to agree to all
of these points. The only probably for me is that lens hood makes
the lens look so much bigger and more conspicuous, that I don't feel
comfortable using it all the time. Also, it will not fit in my
bag attached to the lens, since it adds so much size, and I worry that
I will not put it on every time. The UV filter is always on, so I
never have to worry. Well, you have to make your own decision on

One thing I do agree on is that there is not point in purchasing a
terrific lens with great glass and adding a low grade filter on top of
it. This is why I purchased a B+W brand filter. B+W is
known to sell the highest quality filters, but they do cost more.
But again, why purchase a really expensive lens and cover it with a
cheap filter of bad quality. I also decided on the MRC version of
the filter which is suppose to be more resistant to scratching.
The filter is quit expensive so I figured I may as well spend a little
extra and try to ensure that I wont have to replace it very
often, if ever.
On the other hand a polarization filter is a must. A polarization
filter cuts haze, and adds contrast making many photos much more
pleasing. Most of my landscape photos are taken with the addition
of a polarization filter. Skies look bluer, clouds stand out
more, colors are more vivid, and there is less haze present. A
polarization filter is a must for any serious photographer.
Again, I purchased a high quality filter to go with these high quality
lenses. There is no point in purchasing a great lens and covering
it with cheap glass. The Kaesemann polarizing filter is suppose
to be the highest quality. It is now sold and owned by B+W.
I also decided to get the MRC version to help resist scratches.
For auto focus cameras you will need to purchase a circular
polarizer. Unfortunately, the standard polarization lens prevents
the auto focus technology from working. Circular polarizers do
work as well, but if you don't mind manually focusing you can go with
the standard Linear Polarizers.
At this time I don't have a good example of a photo with and without a
polarization filter, so I do not show any photos at the top. As
soon as I shoot an example I will include it for your review.
