If you own a D70 you simply can't be without this item. Because Nikon chose not to include a mechanical cable release option (or an electronic one either), it is difficult to shoot at slow shutter speeds, even on a tripod, without getting camera shake affecting your images. You can use the timer, but that doesn't always work for your shooting situation. With this remote, you get the same basic operation as a cable release as well as a bonus that you can put yourself in front of the lens and use the remote to trip the shutter release. It also works in combination with the self timer. One small concern is that because it's an IR remote, you must point it at the sensor, which is on the front of the camera. This can be awkward standing behind a tripod, but not seriously. I really enjoy using this product.
