I voted for other. I'd love to walkaround with a Canon EF 300mm f/2.8L I.S. lens.
Is hand holdable.
Would be great for non intrusive candid photos from a bit of a distance.
Would deliver sweet bokeh to separate the subject from the background.
Could possibly be a very nice ice breaker if a cute, female who is interested in photography might just happen to be in the neighborhood.
Looks so freakin' cool, and awesome!
Is different than anyone else would likely be using.
Of course it would be attached to a 1 series body!
