With the constantly changing technology in today’s world, it makes me crazy to a point where I tend to give up. I can totally sympathize with our customers who are new to sport optics. Many times we take calls from shoppers who look at the endless numbers of binoculars and spotting scopes, then call to admit they are overwhelmed by the choices. The other kind of calls will come from experienced binocular users who have used a pair of porro prisms for a long time. They want to replace their binoculars with another porro prism binocular, but the choices are considerably less than years ago as the market has become dominated by roof prism binoculars. Besides the familiarity, customers have specific reasons for wanting to stay with this traditional style binocular.
The main reason our customers still love a porro prism binocular usually relates to their preference for a three dimensional view . The increased space between the objective lenses creates this effect. A reverse porro prism will not have the same 3-D effect because their objective lenses sit close together. The 3-D porro views combined with a large depth of field, have long time users firmly united in their love of a porro prism binocular. Comfort in holding a porro prism style binocular is also a factor. With the extra space between the barrels, your hands have an easy time fully gripping the binoculars.
So why the proliferation of roof prism design binoculars and the decline in porros? For one thing, porro prism binoculars have more moving parts which increase the cost and difficulty of making them waterproof and fogproof. The offset barrels can be knocked out of alignment much easier than their straight barreled roof prism counterparts. Butterfliers usually stay away from this style of binocular since it does not provide a good close focus. But if your eyes crave the bright, three dimensional views of this classic, don’t worry. Eagle Optics still carries many different porro prisms in a wide range of prices.
Do you want to feel like you are part of the action? Be sure to look for a large field of view. The Audubon Raptor, Bushnell H2O, Bushnell Legacy, Nikon Action, Nikon Premier SE, and Swift Audubon all offer fields of view close to or over 400ft./1000yds. A nice feature of these binoculars is the newer style twist up eyecups. All but the Nikon Action include waterproof and fogproof protection.
Are you a staunch traditionalist and still want a rubber eyecup? We’ve got those, also. The Audubon Intrepid, Bushnell Natureview, Eagle Optics Triumph, and the Fujinon BFL still sport the soft rubber eyecups. I have to admit, being a fairly new binocular user with middle age eyes, sometimes I do not have good luck with the rubber eyecups. Currently on sale is the Fujinon 8×42 BFL so I took a look at this waterproof, nitrogen purged binocular. I was very pleased with the feel of the soft eyecups, its 25 ounce weight, and the sharp edge to edge view. With the porro prism’s vintage brightness, 3-D view and good depth of field, I certainly understand why long time porro prism users may not want to switch to the newer features of a roof prism.
