I like to see how well the 16mm holdups on video. I used my 24mm many times and amazed how the edges hold up very well even when I have my focal length as wide as I can, without getting any barrel distortion on the edges.
I Shot a spec for rockstar energy drink the other week with the 16mm and i was very impressed. We had a little issue with the lens not focusing but the 1st AC figured it out.
We were shooting with the redrock.
