This chipmunk is no longer running away the minute I show up at the window. Initially, it was very hard to capture it.

I sure do prefer working with the 2.04 pound Olympus em10 ii + Panasonic 35-100 f/2.8 lens combination than the Sony A7iii with Canon 70-200 f/4L lens + Sigma MC 11 adapter, weighing 3 lbs 7.2 ounces! These two combinations are equal in focal length. Unless I'm working in extremely low light it just doesn't make sense to struggle with the weight plus erratic autofocus of the Canon lens.
