Compared to the twice as expensive Nikon Prostaff 5 10x50, the difference is in size, weight and price. The quality of the image in terms of sharpness, contrast, and other things did not notice that it was different. But the chromatic aberrations of the Aculon A211 10x50 are almost not noticeable, in comparison with the more expensive Nikon Prostaff 5 10x50. The only thing is that Nikon Prostaff 5 10x50 has a very large eye relief, therefore it is easy (with eyecups not extended) to use with glasses, and for the A211 it is better not to twist the eyecups at all - the field of view narrows and the image starts to "dance" - the same will happen if look with glasses. All in all, a great and inexpensive pair of binoculars. Unless the multiplicity is already too big to watch without focus, but this is already understandable. I have no complaints about the quality of the picture)))
