Also, fixed aperture zoom lenses are better for video if you want to actually do any zooming in or out, because variable aperture lenses twitch while you zoom, making the video look pretty bad.

A vari ND filter is nice (beyond coverage of this episode).

If you de-click lenses (which we mentioned) then this is not hard to do and can be smooth. But we really weren't talking about WHILE rolling.

Hi,

Turning the Aperture dial when shooting should really be a no-go, simply because the focus area (circle of confusion) expands/contracts. Also, you will see each noticeable click in the image, mostly rendering it useless for your edit.

If you want to maintain a constant aperture and still be able to smoothly control the incoming light, you need to use a variable ND Filter. These are available from both SinghRay (VariND) and Lightcraft (FaderND) and typically allow you to control light from 2 to 8 stops.

I'm a 30-year veteran of videography just moving over to DSLR video, and I just want to express my appreciation for your podcast. I've been doing a lot of research here on the COW and elsewhere, but your podcast contains some of the most clear and succinct info I've found. Keep up the great work.

Even though you spend a lot of money on a lens, your beautiful lens could have some inherent flaws, but this video tutorial with Robbie Carman and Richard Harrington demonstrates that these distortions can be fixed in an unexpected way. Photoshop Extended CS5 allows you to open video clips and convert to a smart object, which allows you to run a filter on entire video clip instead of just one frame. Menu options within Photoshop allow you to choose your DSLR camera and lens, and if your lens is not available yet, create profiles online at Adobe for your own specific lenses and cameras, then watch Photoshop Extended begin correcting lens distortion.
