How to interpret the zoom power indicators on a camcorder?

Q. I have a photography background with 35mm film and digital cameras. I am on the market to buy a camcorder and I would like to understand the "reach" of the zoom when it mentions things like "10X optical"? I can easily figure out the reach of, say, a 75-300mm lens in 35mm film cameras. How does the camcorder zoom labels compare to 35mm film camera zooms?

A. It is as simple as it seems.

10x zoom means that at 0% zoom or no zoom, the image is at the same size you can see with the naked eye from the same spot and vantage point as the camcorder, and at 100% zoom or maximum zoom, the same image is now ten times larger than its original size (and part of the image may now be so big it went our of frame or out of view).

If you are talking about focal distance or in your case "focal length", that is a different issue. Most built-in camcorder lenses can focus from macro to infinity. In most cases, you can find an adapter to adapt a 35mm camera lens onto the front of the built-in camcorder lens, and then, focal length and "reach" come into play because your camera lens is based on f-stops. Several professional camcorders (such as the Sony PMW-EX3) also allow the removal of the camcorder's lens and the placement of another lens including those from 35mm cameras to be installed instead for specialized filming situations.


What is the best camcorder $300 and under for low light lov budget film?
Q. I an currently writing a script for a fan film based on The Crow. I cannot seem to find a low budget camcorder with good software and low light capability. Most of the film will be shot at night and I want a good clear picture in low light and it has to work with windows movie maker!
I'd appreciate any suggestions cause I can't find anything in my price range.

A. Good low light video capture behavior = large lenses and large imaging chip systems.

Big glass and big chips are expensive. There are no "inexpensive" camcorder with lenses larger than 60mm lens filter diameter + 3CCD (or 3CMOS) imaging chips (1/3" or larger) which is why you can't find any.

Versions of MovieMaker before Windows 7 cannot deal with AVCHD compressed MTS files unless they are transcoded first. Only certain combinations of of Windows 7 and MovieMaker Live can deal with AVCHD/MTS files... No version of MovieMaker will deal with MOV files (unless transcoded, first). Only certain configurations of MovieMaker will deal with AVI files. So I'll say any consumer camcorder or camera that captures high definition video to flash memory or hard disc drive is not do-able because dealing directly with MovieMaker won't happen. No one should ever waste their $ on a DVD based camcorder. As for miniDV tape, MovieMaker can't deal with HDV. But, if the computer has a firewire port, it can deal with importing standard definition DV files. Certain versions of MovieMaker can deal with the MPG files from some consumer cams - no version of MovieMaker can deal with standard definition MOD files...

For $300, the Canon FS series standard def flash memory cams are OK - and they can do stndard definition widescreen - but you will need to use a transcoder like MPEG StreamClip www.squared5.com or HandBrake www.handbrake.fr to convert the files to WMV format so MovieMaker can deal with them.

Good luck!
