Cameras specifically: I have access to a few types
FlipVideo – built in USB socket, quick easy to use, ready for youtube. .AVI files, internal memory (60mins) AA batteries. £80. Not tested in the gym yet. 90mins version available, not available in the UK yet and amazon.com won’t ship to here either. This is a real dummies camera, I’d happily give it to my 8yr old niece to run about with. However this also adds to its appeal. You can chuck it in your bag, carry it about without worrying, pass it to mates (or anyone) without having to tell them how to use it. Its really convenient… and convenience is what stops us using most cameras. I really rate this one. Just gotta test run it at the gym first tho!
Canon Powershot G7 – 10mp, Manual controls, 30fps, slow-m0 on playback. .AVI files. records until your card is full. £250. This is a proper beast. I researched lots of cameras before settling on this one and its the main camera I use in the gym atm. Choose to shoot on 1024×768 @ 15fps or 640×480 @ 30fps, available in ‘manly’ stylish black, so you won’t look like a tourist with it. Great slomo feature for playback. This is a really good camera, everyone that’s ever viewed a video on it has been impressed, and the only person that wasn’t impressed had a £2k Sony VX2000! The G9 has just been released, so expect the price of the G7 to drop. The G9 only adds RAW files for stills and upgrades to 12mp stills. You’re better off getting the G7.
JVC GR-DF420EK – MiniDV, compact, manual light controls, Firewire £150. I needed a cheapo camera for MiniDV stuff and this hit the spot small and is perfect for proper editing purposes. No slomo playback sadly, but won a fair nunber of reviews for features and quality and takes a knock too. Now discontinued, but still around on ebay for a bargain price.
