This showed up in the post today:
It’s a replica Canon 24-105 f/4 IS Coffee Cup! Now I can combine my love of Canon and Coffee! LOL
There is also a 70-200 f/4 Travel Mug but that one is a bit hard to find at the moment and was handed out to the press by Canon during the Winter Olympics. Canon has started to sell them in Canada, so they might be made available to the world wide market soon.
