After much consideration I have decided on getting a good quality HD camcorder that will last me a long time. I'm hoping if I tell you guys what features I need, then you could help poke me in the right direction.

I'm looking to be able to attach filters, grads, lenses etc.

Also good amount of manual controls like apeture, white balance, shutter speed focus etc.

I will be filming fairly fast moving subjects, and I would like fairly good stabilisation and to be able to pan well. But I would also like to film other general things so a good size sensor for low light performance would be nice.

And obviously good image quality.

I would prefer the storage to be some kind of card, like SD or sony's equivalent.

Any suggestions appreciated
