Last winter, I spent a couple days aiming my 18 to 55m Canon EFs lens that I had prefocused to catch chickadees flying in for free food. Occasionaly, I hit it right and actually got an image like this one.
Look forward to C&C. Is there an easier way?

Love your lens selection.....quite smart. Keep the shutter speed to no less than 1/1500 sec.
