Six bons modèles de jumelles compactes

All compact binoculars are a compromise. For one thing, the laws of Physics are against them. The small objectives of compacts put a physical limit on both the resolution and brightness of the binoculars. Close in, in good light, that is not much of a problem, but as distances increase and light levels fall, compacts are always going to reach the limits of their usefulness far sooner than mid-sized and full-sized binoculars. Then too, really compact binoculars, the pocket-sized roof-prism models, are pushing the limits of what can be done with glass and metal. The precision tolerances required to make roofs work at all get even tighter as you shrink the dimensions, and mean that truly compact quality is always going to be very expensive. Finally, the small exit pupil of compacts makes them considerably harder to use than full sized binoculars.
In this article, Steve Ingreham presents us two new truly pocket-sized compacts, a 8×20 and a 10×25, in the HG line from Nikon, two new pockets in the Zeiss’s Victory series in the same sizes, and semi-pocket roofs,the new 8×25 and 10×25 from Celestron.
