The Focus Free 7x50 from Dowling & Rowe is a serious professional binocular with high-quality lenses and BaK 4 prisms - guaranteeing very clear images with high light transmission, well suited to lower light levels and even night use.
Focus Free
The unique focus free feature guarantees instant sharp picture for all users immediately, spectacle wearer's will enjoy the same performance by simply folding down the soft rubber eyecups. Some people describe focus free binoculars as auto-focus, but in fact there is no complicated mechanism to achieve focus as in a camera. Instead the focus is fixed using a specially designed eyepiece that allows the image to be perfectly sharp from the near focus point of 20m to infinity. The results are truly amazing - this clever design even does away with the need for the usual dioptre adjustment on one eyepiece - these superb binoculars really are fuss-free!
SnS comment:
The D&R 7x50FF really is an ideal serious binocular for the professional user. The robust, fully rubber-armoured waterproof body makes it ideal for use in the working environment, and the fuss-free optics make it ideal for communal use by multiple users. The ease of use and quality of view is outstanding and no other binocular functions as easily or quicker than this focus-free model. However, it's as well to tick off the less advantageous points in this type of binocular too.
1. Because of the special design, the close-focus point is more remote (20m) than for conventional binoculars. Hence, the binocular is ideal for use at known observational ranges where close-up viewing is not required.
2. The special design will only work well if your eyesight is fully corrected. If your eyesight does not require correction (lucky you!) there will be no problem using the binocular, but if your eyesight does require opthalmic correction (ie if you need to wear glasses or contact lenses) you will need your prescription eyewear to use these binoculars effectivly.
This no-fiddle, no-fuss binocular will appeal to all including professional users in all fields of use, from coastguards to police forces, from sailors to astronomers.
Includes soft case, retained front caps, eyepiece caps and neck strap.
