Awesome! Mind if I ask you another question (after this one, obviously)?

I notice that my 70-300mm L makes a kind of buzzing sound when the IS is on and it's trying to focus (I'm no audio expert but I'm going to say that this buzz is at least three times louder than the sound of the lens focusing normaly). The sound is not present when IS is off. I bought the lens used so I can't be sure if this is a normal thing or a problem.

The sound doesn't bother me, but it does seem a bit out of place. Any insight would be much appreciated.

Would call it a soft rattling sound, a bit like the cooling fan of a computer. Sometimes it seems loud, other times not but that depends on the the acoustic characteristics of the environment and the other sounds. In a quiet hide it can make some noise.
