Q. I am looking for a camcorder which can take lenses from a digital still camera, like a EF lenses of Canon. Any ideas?
A. I've never heard of one, and I'd be surprised if one exists. Camcorder chips are generally smaller than DSLR's so you'd be losing a lot of light.
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.
