Conclusion: It often happens in our tests that real life verifies brutally all the binoculars’ advantages, so touted in promotional brochures by the producer. Taking this truth into account the Swift Ultra Lite surprised us even more pleasantly. Its praised casing is really interesting, original, solid and it sticks out in a positive way against the background of other rivals from the same price segment. New coatings are indeed doing a great job ensuring high transmission.
Pros: very solid and original casing,, high transmission,, very low coma,, well-corrected astigmatism,, sharp image in most part of the field,, slight light fall-off at the edge of the field of view,, good whiteness rendition,, sharp image already from 1.35 metres,, high quality of coatings and prisms,, long guarantee.
Cons: egg-shaped left pupil,, high chromatic aberration at the edge of the field of view,, a bit too high distortion.
