I totally agree,I often create vignetting ,both dark or light,during post processing!

I found the same problem on my 18 - 250 lens at wide angle; (18 - 22mm). One way around this is to buy a filter that is say 10mm bigger than the Lens thread of your lens and a step-up ring to go with it. My lens is 72mm thread, so I bought an 82mm thread/diameter circ polariser filter and a 72 - 82mm step-up ring for it. Hope this works for you.

Very nice. Is that a loon?
Reminded me of a poem I wrote some years ago. See it below. Your picture is a good illustration of the poem's second verse.
Would you mind if I shared your picture with some friends? I would of course give you credit for the shot! If you are willing to share your name, I will give full credit..otherwise you will just be Jerry. Anyway, here is the poem:

George Lake Evensong


These late summer days
the sun is brittle in skies
of silvery haze.
The light plays
quietly on quartzite grays,
then dives
with sparkling displays
into water like a window
shattered.

But evening like
a waterfowl canoes
across the mirrored trees.
Over the deep blues
of the lake
the last silver arrows
speed in the wake
of the loon,
and then the day is gone.

A friend of mine has been an art history professor for his entire career. For most of that he has also been a photographer. As well, he has also been a judge at photographic events of all sorts.

He tells me that as a judge, and in the profession, mild vignetting is considered plus points. The reason is that a vignette keeps the eye from wandering off the corner borders of the photograph. Adobe and other publishers of editing software obviously know that if they create tools to add vignette to images.

It might be well to know how the judges score on this if you are planning to enter photographic contest events.

He also told me that very strict events only allow for white as a mat and MAY allow for a slightly wider bottom measurement. That's for both B/W and color photographs. Colored Mats will lose points in strict art judging events.

This can mostly be verified by searching the internet for judging protocols for photographic art.

Be hell to enter an event and find that you lost by the points taken away for colored mat, or that you could have won by points added for a mild vignette.

The step up ring is a good solution and very versatile...

Buy one size step up ring... quite large. Then buy step ups to that size for all your other lenses. Then you can buy better grade filters as you are not buying a set for every lens. The only things that differ are the stepup rings, which are less expensive with no glass in them.. minimal quality issues.

I get vignetting at 10&11mm when stacking my thick UV and CPL on my Sigma 10-20 lens. Knowing this allows you to decide how and when you want to use the effect. This not a fault of the lens of filter makers, it just is. PrarieSeasons is correct about using slim filters.

wlgoode Loc: Globe, AZ

Just because it is "slim" is no guarantee of no vignetting. Go to a store and try one out first before you buy it online. Or maybe start a thread asking others about slim polarizers and that specific lens.

Greg Loc: Maryland

There are times and reasons to stack filters.... This ain't one of them. I would presume the UV is on there for lens protection, if you are going to put on the polorizer, there is no need for the UV, so remove it while you are using the CP.

I don't see vignetting here - just the effect of the right side of the lens looking at the magic 90 deg angle from the sun.

Well, that's not adequate to diminish the poor lil' ol' animal's habitat further - we're already closing in on them from all angles and leaving them no place to go as it is without photoshoppin' the hell out of their environment. :-)

why are you surprised, we're doing it to ourselves.

gessman Loc: Colorado

This would cause me to wonder why they just don't go ahead and dock for a print not being B&W and museum quality... Sounds like we're hanging onto some stuff from the past and letting other good stuff from the present be a problem. There is, after all, the color wheel and the concept of 'complementary' colors. I'm afraid I don't get it.

gessman Loc: Colorado

I'm not surprised at all. Didn't mean to imply that.

gessman Loc: Colorado

Please pardon what may initially appear to just be my "Monday morning quarterback's acerbic disposition" but, "Caveat Emptor" implies that YOU should KNOW before you GO. Once again, it's the "order taker" vs. the uninformed customer. Photography can be complicated and often it's no match, and just as often, you lose. "Blind leading the blind." Resources are all around us. Ask, but not the order taker, "what do I need to know before purchasing a CPL for an ultra-wide zoom lens." Call ahead to the store and ask the manager. Ask here. Ask Google. Ask Youtube. Ask someone, or just read. If you've gotten far enough along to be owning an ultra wide angle zoom and wanting a CPL, you are too far along to not suspect some caveats connected with putting the two together, I would think. Let's not blame the poor ol' minimum-wage store clerk. It might have been his/her first day. Not a butt chewing but a lesson learned - and for others....but probably won't be considered to have been necessary but then the original question remains and begs for an answer, an answer that should have been in place before the purchase.
