Conclusion: The final result of the Swift is nothing to be ashamed of. The problem is that I expected a slightly better performance. The Swift fares, by and large, like the Delta Optical and the Weaver Grand Slam; it is cheaper than the latter but more expensive than the former and this is not good news. The transmission was the thing that disappointed me the most.
Pros: solid and handy housing,, small weight of the binoculars for this equipment class,, well-corrected astigmatism,, sharp image in the most of the field of view,, good blackening and cleanliness inside the binoculars,, high quality BaK-4 prism,, good guarantee conditions.
Cons: average transmission,, visible coma,, distinct brightness loss at the edge of the field of vision,, slightly egg-shaped exit pupils.
