Letus Hawk on Canon my 60D / 85mm F/1.2L
Don't forget that periodically Letus auctions off a few items starting at low prices with no reserve if you want to try and grab either the Letus DSLR Cage, Talon Rig, or Hawk View Finder possibly for less than half the normal price. They don't always have auctions running all the time, but right now you can check out the latest Letus auctions at their eBay store (click here).

Letus35 Letus Hawk DSLR Viewfinder
Here's an older video about the Letus35 Letus Hawk DSLR Viewfinder and Letus Talon K2 rig. The video is really only 21 days old, but I heard a bit in the pipeline that there will be some additional gear available for the Hawk VF's to make them more modular with a quick release. So what you see in the video above will just get better.
Just a reminder for those who were really impressed about the Letus Hawk View Finder, but weren't keen on the Hawk VF Carbon Fiber design, the brand new Letus Hawk VF Aluminum version is estimated to be available in 3 days. All the gear they have available now will be compatible with the new gear you should be hearing about soon. Here's the link to the new Aluminum Version soon to be released: http://www.letusdirect.com/cart/letus-hawk-aluminum.html
