Here's another pic of another show.. this one was held at the Big 4 bldg on the Stampede Grounds. Again, lighting isn't great but it was certainly better than the what it was in Lethbridge (see previous pic). The pic has been cropped to get a close-up of the two dogs (btw, the dog on the left is my dog. He got his champion title that weekend).
and here's a pic of an outdoor show (taken last summer at Spruce Meadows) where it would be great to have a decent telephoto lens.
