Binocular-camerasFor Bird Watcher's Digest, September 2011by Michael and Diane Porter Michael and Diane Porter wrote the following review, which appeared in the September, 2011, Bird Watcher's Digest. It discusses the necessary design principles of a binocular-camera. It also gives an in-depth look at the Bushnell Image-View SyncFocus binocular-camera. The binocular part of the binocular-camera The binocular has decent optics, but most birders would probably want something better for their primary birding binocular. Here are a few concerns. The focus knob is stiff. Your index finger has to do a lot of work, because the SyncFocus slides the front lens elements in and out, both in the binocular barrels and in the camera lens barrel. You can observe the movement by watching the front end of the binocular while you turn the center focus knob. One would want to be careful to keep dust from accumulating inside the barrels where it might impede the sliding action. If you wear glasses, the eye relief of 15mm may not be enough for you. Also note that the eyecups are the roll-down, rubber style. Most binoculars now come with twist-up eyecups. |
