As the top model in Canon's MiniDV line this year, you shouldn't expect earth-shattering improvements from the ZR850 over last year's models. After all, manufacturers seem to be putting more resources into DVD and hard drive-based models. The overall design keeps what we referred to last year as the "palm-friendly design," and again bumps the optical zoom up a bit, this time from 25x to 35x. As we've come to expect from Canon, the ZR850 delivers admirable color reproduction in good lighting, but it can't keep up with the competition when it comes to low light.
One noteworthy improvement over last year's ZR700 is this model's sensor, which has been bumped up to a 1-megapixel CCD, instead of 680K pixels. This makes for slightly better still images, though they're still not near what you'd get from a dedicated still camera. One noteworthy omission compared with the ZR700 is the ZR850's lack of an analog-to-digital converter. If you're looking for a way to convert analog video to digital, you'll have to look elsewhere.
We like the layout of the controls on this year's ZR models. All controls are within reach of your thumb or fingers either on the right side or on the bezel of the 2.7-inch wide-screen display on the left side. This is much better than designs that put important buttons on the left side of the body behind the screen, where you can't readily see them. Plus, Canon redesigned the menu system, so that it's more like the one on its digital still cameras. When you press the function button, a list of options appears on the left side of the LCD, and the choices for each of those options appear in a strip along the bottom of the screen. Last year's ZR700 had four buttons below its LCD screen, but the ZR850 only has two, Function and Digital Effects. Canon now makes you delve into the menus to switch between wide-screen and 4:3 recording modes, or to turn the camera's rather low power video light on or off. The lack of an accessory shoe or microphone input is annoying, but that's also typical of camcorders in this price range.
