Panasonic Demo

Recently attended Panasonic's demo at DV Depot here in NY. It was pretty good. A bit basic but it was nice to see the side by side comparisons between the HVX200A, HPX500, and the HPX2000. I must say, I'm pretty impressed with the AVC-I codec. Panasonic has definitely upped the ante with this and practically guaranteed a long product life for their P2 technology. After the demo I realized that my Digital Production Camera data sheet had several mistakes on it. They have now been fixed. Have a look if you're interested.

Film Camera Gates vs. Digital Sensor Sizes - numerical data

I was going through some old research the other day and found something I made that I feel is worth posting here. It's basically a table that lists the physical dimensions of various film camera apertures and video camera sensors. Awhile back I was trying to find a "normal" lens size for each format, i.e., in Super 35 a "normal" lens is considered to be a 35mm. Of course by "normal" lens I mean, one that basically recreates the natural, undistorted perspective and field of view of the human eye.

This is determined by measuring the diagonal distance of the imaging area (sensor or aperture). A lens size that corresponds to this diagonal distance in milimeters theoretically should recreate an undistorted Field of View. In practical application the actual dimensions of 1/3" and 2/3" camera sensors varies widely from manufacturer to manufacturer. The "1/3" and 2/3"" label are used more as a camera classification than an actual size. Therefore, there really isn't a way to accurately systematize and correlate lens sizes and Field of View to video camera sensors. This information can help get you in the ball park though and is useful for finding equivalent lenses across various formats.
