Hi everyone I am just starting with bird and nature watching, etc. and I bought my first serious pair of binos. I got the Nikon Aculon 211 10x50 (a decent budget binocular) and I noticed the mention that it has aspherical lenses as a feature, something that's not mentioned at all in other more expensive models. I wonder now if it is such a basic feature that is needed in order to have edge to edge sharpness in high end models, something so obvious that is not even mentioned. Another doubt I have is whether the Aculon have some kind of chromatic aberration correction whatsoever. When I used cheap telescopes as a kid, I noticed that the chromatic effect was super annoying, and although these binos have some, it is nowhere near the level of the cheap telescopes. I know it doesn't use ED glass, but it might have a achromatic doublet or things like that, this might also it be a feature not worth mentioning since it is expected to have at this level of quality. I see the websites of these companies are a bit obscure about the specifications of the binoculars. They list the typical characteristics like magnification, size of objectives, etc. but say nothing about the objective amount of chromatic aberration, sharpness in the center and the edges, etc. Thank you in advance for your responses!
