I hate vignetting. It’s a righteous pain. And now, I have to deal with quite a bit of it. Even the vaunted Photoshop can only fix so much. …let me back up and explain.
This past weekend, I did a car show shoot marathon. I took Friday and Monday off work. Friday was for a shoot, Monday was for recovery, and both were wise ideas. The Friday show was called the GM PowerTrain show, was hosted at the local GM plant, and allowed anything that had a GM powertrain in it. There was even a Model A Ford with a Chevy motor there.
I brought two lenses – my Tamron 24-70 f2.8 and my Canon 70-200 f2.8. Due to the space available to shoot (the cars were packed pretty tightly), I found I used the Tamron 90+% of the time. Since Saturday had two car shows lined up, I ran down to my local camera store and asked him if he had any circular polarizers for an 82mm lens. He only had one brand, but it fit, so I got it, and it only cost me $65. Kind of a break from the B+W’s I usually get.
Well, here’s where the trouble began. I couldn’t see anything on the LCD (and yes, I use the viewfinder, not live view, but I do review from time to time), but when I got back home after a very long day of shooting, I discovered these cute little corners on almost all of my shots!

As I later read, this is apparently a known problem between “normal” c-pol filters and wide lenses. In order to overcome this, you need a special, thin c-pol filter.
So if anyone is buying a circular polarizing filter for a wide angle lens, please be aware – conventional circular polarizing filters will cause vignetting. Make sure to check with your camera store to ensure that it is compatible with wide-angle lenses first!!
