Alpen Optics Teton 10x50

17 February 2010
  • Conclusion: The result of the Teton 10x50 speaks for itself – it is really brilliant. It’s enough to say it is only worse than a big, heavy, porro-prism Docter Nobilem’s result. After all, the Docters are a class of their own. Still, there’s one but…it’s difficult not to have an impression that one part of these good results was reached by limiting the binoculars’ field of view to these 5.8 degrees.
  • Pros: relatively solid and light housing as for the 50 mm class,, good transmission,, low coma,, slight astigmatism,, well-corrected distortion,, field sharp almost to the very edge,, slight brightness loss at the edge of FOV,, very good whiteness reproduction,, good quality of prisms and coatings,, small minimal focusing distance,, slight inner flares,, very good guarantee conditions.
  • Cons: truncated left pupil,, a bit too high chromatic aberration,, for this price class the field of view should have been a bit larger.
