I use fewer protective filters these days than I did several years ago
and as a result have an ample supply of UV's and Skylights around. The
only camera where I routinely use a protective filter these days is the
A* 200mm macro, mostly because it is expensive, the built in hood offers
little protection, and it occasionally tips into mud when I'm trying to
contort the tripod into the right position. Nice thing is that I can
just remove the filter and rinse it off if it gets muddy.
I don't know when Pentax stopped making SMC filters but they are truly
very good wrt coatings and flare.
Of course, I have no use anymore for warming filters, tungsten filters,
UV filters, etc... I do still use Red, Green, Yellow and Orange when
shooting film at times....

I've replaced a number of filters over the years. They did what I wanted
them to do, provide a relatively inexpensive insurance against f******
up and damaging an expensive to replace front lens element.
After they took the hit, I said goodbye & bought new filters to replace
them.

I use skylight filters on a few lenses with no issues. I think plain
glass is probably best, but I bought skylight and UV filters back in the
film days and see no need to replace them. I wound up with some skylight
filters because I stumbled onto some Pentax SMC skylights at a good
price and I figured that a SMC filter would be a good choice to minimize
flare.
These days I don't use protective filters on many lenses, though I do
use an SMC skylight on the A*200mm macro, which accounts for most of my
shots. The nature of macro work - this lens has been poked, gone face
down into the mud, and suffered other indignities that are less frequent
in general shooting. Unlike the 100mm macros I use, the front element is
not recessed so I like to have the protection of a filter on it.

One of the several reasons i wanted to get the Pentax 17-70 was its
filter size. I have a number of 67mm filters and did not have to add
to the lot. Although the Sigma is a much nicer lens IMO even with the
reverse zoom, buit its a 72 mm filter. The salesman asked if i needed
protection, and i told him no need i did not want any more children
<ba dum>
I said i'm sure i have a 72 filter some were, ( opps they are 77mm)
and he said if not come back and he'll set me up, "JUST DON'T GET A
SKYLIGHT" he said. I did not ask him why he thought that way, but then
it started to think about it.
Why not a skylight for protection, is the UV1 better suited,??
