binocular for field viewing raptors... - 04/24/2012

by John F. from Southwestern Idaho

I recieved a pair of Kowa BD 32-10 binoculars from Eagle Optics and have had them in the field for several days and wanted to give an initial review.

Motivation for getting a 10 power was to improve my chances to identify local hawks and falcons at distance. Moving closer to take advantage of my 8 power would often result in a fly off before catching useful detai.

Weight and size - the BD is a little over 19 ounces and pleasant to carry in the field. The size - 5 inches by 5 inches by 2 inches - is comfortable to use.

Outer covering - I like the green and black rubber armoring, it has indentations and non slip texture that makes for a secure feeling grip.

Eye relief - more important to me than weight and size as I wear prescription lenses. The Kowa has usable eye relief right at 15 mm. The eye cup adjustment has 4 settings and is solid - a definite click at each stop.

Field of view is advertised at 315 feet/1000 yards - which is too narrow. In practical terms, I could not follow birds in flight up close as easily as I could with a smaller power vortex product. But to get more field of view in a quality 10x32, I believe I would need to spend significantly more.

In the field. I was able to identify "that large raptor," as an Osprey and see the variations in red tail hawks. The Kowa got me close enough to identify a female Kestrel and watch as she enjoyed a small mouse for breakfast.

Optic performance - is adequate, with a very slight change in clarity at the edge of the view, a wide sweet spot, and on occasion certain edges will have either a very faint yellow or blue fringe but this is not consistent. The view is clear and the resolution adequate. The Kowa has Schmidt/Pechan roof prisms, fully multicoated lens that provides a bright view. It seems to me that it is a step - albeit a very small one - below the current XD/HD optic glass on the market.

Objective size - 32mm versus 42mm - the difference is not noticeable to me until about 10 minutes before night fall. At that point, the 8x42 bypassed the Kowa in performance in terms of light gathering. The diopter adjustment works well but it is does not lock to prevent change in setting during use and for the price, this is a significant over sight on Kowa's part as binoculars with comparable prices have this feature.

If you are looking for a rugged, small binocular that can work to watch birds at distance - raptors, waterfowl or birds in difficult but open terrain, the Kowa is an great tool for that purpose.

This little binocular earns a strong 4 stars - I am pretty happy with it. A wider field of view and a locking diopter would have resulted in an enthusiastic 5 star rating.

KOWA BD 10x32 - 03/12/2009

by RFG from Houston, tx

I was looking for a medium to small pair, but wanted some power for detail. I have a 12x50 and 10x42 and 8x36. Most small 8X's don't have the detail I need at distance. The Kowas read like they had good definition. The good news. They do have good definition. and...they are built extremely well. They are light. Also, they have a whole lot less chroma-effect than my Legends and Monarchs. I can see them as premier birding binoculars. The bad news. The focus is extremely fine, meaning you need to absolutely dial in every object change. The detail, clarity are there, but you have to tweak the center focus knob almost constantly. The other thing that suprised me, was because they are built so well, you basically have a 10x36 body. I'm glad it's built so solid, but geez, I doesn't necessarily make for a "compact" compact. Another characteristic is the tight single hinge. I takes both hands and determination to open/close the hinge any. I like that though, once you get it set, it won't change on you. I tested it hard against my 10x42 Monarchs. The Monarchs seem to have better utility up close and in the evening ( greater focal field and bigger objective lens). The KOWA's optics excel at a distance, where constant focusing is not an issue. The optics are great and they are built like a tank I just don't think they are as user friendly as the Monarchs. But, it's probably just the 10x32 package, it's a tough go and this is a quality effort and a handy pair for long range detail.
