Thanks, Ben. Only once, when I switched over from slow motion to normal (24fps) did I notice some jitter, but it's hard to say whether it was the lens or me - I just happen to get tremors every now and then (it runs on my father's side of the family). The shot of the caterpillar was made in ETC mode, and even then, the optical stabilization saved my butt. I never use stabilization in post, so what you see is what you get. Just like all the talk about 'plasticy' skin tones or 'digital' looking images, I think it all comes down to lighting and correct exposure. In fact, I like this lens so much, I'm reluctant to to use my once-favorite 12-35mm f/2.8. And just in case you didn't read the details in the YouTube video, all of the shots were made with sharpness turned down to -4, with no sharpening added in post.
