Squirrel!

Shot with an old Canon EOS-1D Mark IV & EF 24-105mm f/4L IS.

These photos are pretty cropped, but the 1.3x crop factor of the APS-H sensor in the old 1D pro sports/wildlife bodies added just enough effective focal length for me to take the shot. I wouldn't have bothered if I'd had the 24-105mm on a full frame body.

Nikon's 24-120mm f/4 VR is a better focal length range for a walking-around zoom, in my opinion.

What I wish is that either Canon or Nikon made a good constant-aperture stabilized 35-135mm, since both the 24-105 and 24-120 are wider than I need at the wide end and not quite long enough on the long end, but alas. 

At least when you slap the 24-105 on the APS-H cameras it becomes, effectively, a 32-137mm. I wish Canon hadn't discontinued that sensor size when they unified their 1D and 1Ds line into the 1DX back in 2011.
