I've been freelancing as a video producer and DP since July of 2009. I've traveled the US and abroad shooting reality shows, web videos, nationally broadcast TV commercials and producing content for DVD. Some of my clients include: Walmart, ESPN, Audi, Animal Planet, MTV, CMT, HGTV, Travel Channel and The Outer Banks Tourism Board in NC.
Shoots on: Canon C300, C100, RED, Panasonic AF100, Varicam, EX3, DSLRs, you name it!
EF-S is a menu setting that electronically crops the sensor a wee bit to avoid vignetting when used with APS-C lenses. This setting must be applied here, though it was not needed.
