Conclusion: Fortunately for Alpen here everything went fine. The result of the new model is not particularly better than that of the old one but, taking into account the fact that it still remains excellent and the price stays at a roughly the same level (currently you can even buy it cheaper as it is being promoted), it would be difficult to carp about anything.
Pros: solid casing,, good transmission,, very low astigmatism,, slight coma,, quite well controlled distortion,, good whiteness rendering,, high quality of coatings and prisms,, low flares, imperceptible light fall-off on the edge of the field of view,, minimum focus already from 1.6 metres,, good warranty conditions.
Cons: noticeable chromatic aberration on the edge of the field of vision.
Conclusion: I ordered the Alpen Optics Wings ED 10x42 pair of binoculars because I was very curious how it would fare. Why exactly this instrument? Let’s have a look at the following chart . The Olympus EXWP I and the Vortex Viper were our big 10x42 test hits. The Pentax DCF ED 10×43 is a more expensive model of a renowned producer with low-dispersion glass in objective lenses.
Pros: solid and physically light casing at the same time,, field of view a bit wider than that of its direct competitors,, chromatic aberration well-corrected,, slight astigmatism,, decently corrected coma,, slight brightness loss at the edge of the field,, good darkening and cleanliness inside the inner tubes,, exit pupils only minimally egg-shaped,, good quality BaK-4 prisms,, lifetime warranty
Cons: transmission could have been higher,, it should have been sharper at the edge of the field of view.
Conclusion: Our big 10x42 binoculars test showed that there are plenty of binoculars sold under different names on the market but often coming from the same factory in China or in Japan - the differences between them are very slight. When the Alpen Optics Rainier 10x42 fell into out hands we did a comparison of different models’ parameters and it showed that the Rainier is very much like the Bynolyt Albatross, tested by us before.
Pros: solid housing,, large and sharp field of view,, good transmission,, very low astigmatism,, slight coma,, distortion quite well-controlled,, excellent whiteness reproduction,, high class of coatings and prisms,, low flares,, good blackening inside,, minimal focus already from 1.5 meters,, good guarantee conditions.
