I don't know but i'm in the same price market.I do know that I want a fisheye lens, the shots are night and different with one.
both of ya-get a canon hv30 or an hv20. i have one and i love it. heres a sample.
hv30 test on Vimeo
no color correction on that clip. compression isnt that good cos i wanted to keep the file size down. you should be able to get an hv30 for about 500 now new. prolly cheaper used. also, for a fisheye, get this lense:
Amazon.com: Opteka Platinum Series 0.3X HD Ultra Fisheye Lens for Panasonic SDR H80, G90, S26, S79, S25, H200, H18, D50, D310, D230, D220, & D210 Digital Video Camcorders: Camera & Photo
its exactly like a century baby death. i cant see a difference and ive used both. only difference is the opteka is 99 instead of 390 for a century.
