Don't forget that you can use a Nikon adapter (same as for the JVC cams) to use Nikon lenses. Most of these have aperture rings. You can also use Nikon mount indies like Sigmas - they do a nice 100-300 f4 a 120-300 f2.8 etc.

wow! i didn't know this. I shoot nikon for stills!!!

where are the details of this adpater???

i assume its manual focus only though? I think the sony alpha lenses will be autofocus....

MTF make them, check http://www.mtfservices.com/products/...sadaptors.html
Also www.lesbosher.co.uk Les will make whatever you want.
JVC list it as an accessory for their HD100/200 series I think.
Yes, it'll be manual everything, but to me that's the only way to work seriously, especially with specialist lenses like tele and macro.
