I plan on getting the video assist the day it becomes available. I'd like to if possible use it as an EVF as well. One solution I can think of is the GRID 5.0 viewfinder made for 5" monitors. http://www.gridaccessories.com/produ...-0-viewfinder/
I used to have one of those for my EF 2.5K when I still used an offset shoulder rig, pretty much just used the actual BMCC monitor as my viewing source. It's pretty decent and helps a lot on a bright day, more so than a simple hood.
It would be sweet if BMD could release a "side finder" type of unit like SmallHD just came out with for their 5" monitor.
