But no film maker or camera buff will tell you digital zoom is to be relied on. If you need that much zoom shop for cameras that allow adding better lenses. Another side effect of high zoom rates is putting the camera on a solid tripod.
I have an HC V-180 panasonic Camcorder. It has a 52X optical and 90x intelligent zoom. It can maintain a relatively clear image at 133X in digital zoom. My question is, since 52X is the maximum optical zoom for HD camcorders, would I get a better image at 133x from a 4K camcorder with 25X optical zoom at 133X simply because the zoom is starting at 4K as opposed to HD and the camera will most likely have a larger sensor?
