Optyczne.pl 
The Albatross SHR series consists of two solid roof prism binoculars with the parameters of 8x42 and 10x42. Both instruments’ construction is based on the BaK-4 prisms covered by phase correction coatings. The producer assures us that, in order to get the best transmission possible and to damp down unwanted flares, all air-to-glass surfaces were covered by antireflection multilayer coatings. Additionally, the prisms put in the Schmidt-Pechan system, which demand the usage of just one reflective surface, are coated but not by ordinary aluminum, which reflects just less than 92% of light, but by special 60-layer SHR dielectric coatings which are supposed to eliminate the light losses on prisms to about 1%. According to the producer, the overall binoculars’ transmission level reaches over 90%.

When it comes to the barrel it is made of light but solid aluminum with a high quality rubber armour which acts as a shock absorber. The binoculars are waterproof and nitrogen-filled.

The SHR Albatross series devices come with a 25-year-long guarantee.

Summary


Pros:
  • solid housing,
  • wide and sharp field of view,
  • very good transmission,
  • 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 1.45 meters,
  • good guarantee conditions.

Cons:
  • the right pupil is slightly egg-shaped,
  • distinct chromatic aberration at the edge of the field of view.



The Albatross managed to accomplish a very difficult feat – that of manufacturing a set of binoculars with a wide field of view which is sharp and corrects basic off-axis aberrations well at the same time. The device is not cheap because the price of almost 1000 USD cannot be considered as low. Its score in our test speaks for itself, though. The binoculars attack the positions of the biggest market players with the field of view wider by 0.2 degree and being about 800 USD cheaper. It commands respect!

The Albatross, next to the Docter, is the most expensive pair of binoculars in the 6.5 degrees field of view class. Its score in the test is significantly better than that of its rivals and it might defend such a steep price in a way.
