Not as sharp as it should be because I was laughing too hard. A photographer put his brand new 70-200mm with its brand new teleconverter on a picnic table as he was photographing a carousing bull moose and four cows. The moose took over the area near the picnic table and it was six worried hours before that photographer could retrieve the lens. We arrived back at the campground around 11 a.m. to find that photographer and several others trying to photograph the moose without the lens and picnic table in the image.
