I'm looking at getting a .6 or .7 wide adapter lens and looking for any reviews or input. Here's the ones I'm looking at..mostly for weight and a bit for price.
16x9 .6 adapter
Cavision .6 adapter
Cavision .7 adapter
Century Optics .6 adapter
Any input appreciated, thanks.

Hi Scott and welcome to DVinfo. We have many threads on this topic already. I made some comments on the Century .6x adaptor here: http://www.dvinfo.net/conf/1170465-post9.html

Also see my comments on the Century .75x adaptor here: http://www.dvinfo.net/conf/sony-xdcam-ex-cinealta/235715-ex1-wide-angle-pros-cons.html

Based on this, I have a nasty suspicion that anything wider than the Sony .8x is going to vignette. Let us know what you end up getting and how it works for you.
