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).

Master Cinema Series Launch Party
Vimeo member Tom Guilmette has a video from Shane Hurlbut's Master Cinema Series launch party. The launch party in Los Angeles showcases the first three main rigs in the product line from a handheld cage, to shoulder rig, and larger eye-leveling studio setup. Definitely looked like tons of fun and even Freddie Wong made it out to the party. More information about the DSLR rigs and accessories in the product line can be found at the website https://mastercinemaseries.com
