Review on Pentax Binoculars UP 8-16x21 Black by Wiktor ᠌

Because of this, it is still possible to master the return, which is the main cause of the interpupillary distance, but it is no longer comfortable to use. These are some advantages: Because to aspherical lenses, bak4, tiny, reasonably light, retractable eyecups, and a near minimum focal length of around 3m, even at maximum zoom, all you get is a clean and sharp image throughout the whole perimeter of the lenses. Cons are: 1) The interpupillary distance is the biggest drawback; the maximum is 73.5 mm, but I fall short by around 1.5 mm, giving the appearance of a little double vision; nonetheless, this is normal for people who already have eyes. 2) Although not essential, I would want a slightly tighter focus wheel. 3) The image is slightly darker at the greatest zoom, which is noticeable given the changing magnification, but the sharpness remains the same and the image is just as clear as at the smallest zoom.
