Re: Is the C300 worth all the hype?
 

Well I'm used to shooting with EX1's and F3's so I guess Ive built up my arm muscles a bit. But it's quite light especially with a L series prime lens on it. Holding it up to your face with elbows tucked in, right hand in the grip, left hand under the body or lens, I would imagine that 5 minutes without a break would be fine. It's a great candidate for a monopod.

It sort of reminds me a bit of the Canon Scoopic in its arrangement. Of course, that only took 100ft loads, so was limited to 2 mins 47secs at 24 fps.
