They were showing matte boxes for DSLRs, which you can buy separately ($799.95), or as part of a kit with an adapter base designed for use with DSLRs ($229.95 separately).
- Genus GMKBAS-72 Basic Matte Box Kit with French Flag and 72mm Adapter ($799.95)
- GMB/DSLR Adapter Bar System ($229.95)
- Genus GMKDSLR-72 DSLR Mattebox Kit with 72mm Step-Down Ring ($974.95) Note: there are several different models with different sized step-down rings.
Also on display was the Genus Camera Shoulder Mount System ($872.50). This item is listed by B&H as "usually ships in 7 to 14 days," though the guy at the show claimed they were new and wouldn't even begin shipping until July 1st (which I guess is about 7 to 14 days.) The front and back part of the rig are at slightly different heights, with a sort of cantilever, and you can switch this around based on your preference.
The follow focus shown on the rig (below) is not included in the price. Their follow-focus unit has reversible gears so it will turn the "right" way, whether using Canon or Nikon lenses.
