Personally I wouldn't use USB even 2 for video work. Firewire was designed
specifically for video work, it can cope with the continuous transfer of
large amounts of data and you can control the cam from the editing software.
USB2 although speed rated faster than firewire, it is burst speed rather
than continuous and you'll find you have problems when working with dv-avi
files. These are the best ones for video work.USB 1.1 will not work with
video capture in anyway. Cams may be described as having dv/ieee1394 or
i-link which are all firewire by different names. Any dv cam should have
firewire.
Most cams these days have usb for download of stills taken by the memory
card, which you can't do using the firewire connection.
I would certainly go with Johns recommendation for Minidv, still the best
for quality, and as he's already mentioned size, the best thing is to go to
a shop and handle a few cams and see which you like the feel of and then ask
for help with those models.
I'm a canon man, prefering their colour rendition, whereas John having used
Sony's may well look at a canon image and wonder why it doesn't look right
to him.
You ask about accessories, a normal battery, once worn in will last about
45/60 mins with the viewfinder and most models you can get a longer lasting
battery, but beware, bigger batteries mean more weight, which may throw the
nice balance of the cam out. Get an nd or uv filter, best way to protect the
lens. A tripod is worth it's weight in gold for nice steady pictues,
especially if you want to sell people a horse, so get a good one, preferably
with a fluid head, but if you can't run to that, check them out for rigidity
and how smooth the pan is.
Also look for a cam with dv-in, so you can archive your material back to
tape, still the best and cheapest way for doing this.
If you get a cam with av-in as well, you can use it for doing things like
converting vhs tapes to the pc, recording the tv etc.
Do not be swayed by the vast digital zooms, they are useless.
