this rig is fantastic and allows you to focus while being handheld. that's almost the most important thing with these cameras. extremely portable. here's the part i didn't learn until the cavison. build quality is very important. this unit is priced at 695 but it is machined well and was custom fit for DSLRs so the ergonomics are right. You can also turn the handles upside down and gives you a more eng style. ofcourse there are other rigs at this price. i had seriously considered the redrock THE EVENT but i found out that the dslr plate doesn't allow you to change the battery without removing it. i also looks at the gorilla kits from zacuto, found those things really awkward and unbalanced with a heavy lens and as everyone knows overpriced. this unit fits nicely on the tripod using my same quick release. this system will allow you to later attach a chest pod or a shoulder mount or follow focus, matte box if you want.
here's a video i used with this rig
music from jon brion. little person from synecdoche new york. shot on 5d mark II. brooklyn bridge park, dumbo brooklyn.
never ending rain in the city. used it as an opportunity to test timelapse using intervalometer as well as my new rig in the park near my place....
open shot was time lapse using intervalometer. kept shutter open for 1 second.
lens: 24-70mm f/2.8L (my favorite)
