My friend Ellen was excited to show me her new Canan f2.8 lens with a range of 70 to 200mm. She asked if I wanted to borrow it for a week and I said yes (of course). With 200mm as the maximum zoom, its capability as a wildlife photography lens is limited, but still very useful for some circumstances. Many of the days were overcast and that made the 2.8 aperture very handy. It is also a high-quality lens so even subjects that are a bit distant will still be sharp.
I experimented with the lens mostly in the backyard where I know I have a steady supply of subjects near the birdfeeders. White-breasted nuthatches turned out to be the best subjects as they perched in a tree close to the feeders before coming to get a seed. Here are some of the results. The lens has since been returned but it was a joy to play with it for a few days. Thanks Ellen.
