I have to explain the following image and why it looks the way it does. Our first day in Banff National Park, we went for a walk down to Bow Falls, just outside of downtown Banff. While we walked, I would stop to make photographs, and I stopped to make this one. I got the tripod set up, and composed the photograph, and got the exposure figured out. It would be a six second exposure, with my neutral density and polarizer filter on. So, I started the exposure, and turned my back just real quick to see what Gina was doing. I only had my back turned away for one second. It was just one of those quick turns. When I turned back, I turned just in time to see the tripod tipping over. I jumped to try to save the camera from crashing to the ground, but I was too late. My camera face-planted right into the dirt. The fall crunched the two filters, and bent the front of the lens in (I was using a Tokina 12-24mm), sort of like a bike wheel after a real bad bike wreck. As far as I can tell the glass of the actual lens is ok, but with the front of the lens bent in the way it is, I can't get the filters off to really check out the glass. Even if I could get them off, I wouldn't trust the lens to be able to focus and operate properly. The camera body itself is ok, thank goodness. And I did finally just get a replacement, but this time, I got the Nikon 12-24mm. I should have just gone with that one to begin with, since the Tokina had some issues (chromatic aberration being the worst) that I had to fight a lot. But, I guess it's good that the cheaper Tokina got smashed, and not the more expensive Nikon.
The whole ordeal could have been prevented if I'd have checked a bit better on the stability of the tripod. While I had my hands on the camera, it was fine, but its center of gravity was forward enough that once I let go, gravity was allowed to do its thing. So, kids, learn from me and check your tripods.
This is the last photograph that lens made:
