Opticron Discovery WP PC 8x50 Binoculars, Black

Product Information

Why is it vital to evaluate certain qualities while selecting the best product for your requirements and circumstances?

The Ultravid HD-Plus 50 binoculars are specifically designed to give you a clear view of your target even in dim light - from dusk and into the night. They deliver excellent contrast and an image brightness that, when combined with their large lenses, make the Ultravid HD-Plus 50 the per fect binoculars for hunting in the darkest conditions.The relatively narrow field of the 8x50 is simply a geometrical consequence of its large size and low power. As a result of the narrowness, however, the edge of field will be seen as much more sharply focused than in a binocular with a wider field of view. Another benefit is the long eye relief, which will be an advantage if you need to wear glasses or sunglasses while viewing. Not many of us have used or even seen them but two that have are Hermann (post #4 above) and Altavista, who commented on it here: https://www.birdforum.net/showpost.php?p=4032574&postcount=54 You might be interested in this test report from a German hunting magazine which includes the Zeiss 8x56 FL, Swarovski 8x56 SLC and the Leica 8x50 Ultravid. I would not hesitate to go for the 8x50 BA. Although a bit dimmer (about 6%) than Ultravid due to its silver rather than dielectric prism coatings, in low light the large exit pupil will supercede the few percent transmission difference. If it's dark enough that your pupils open even as far as 5.5mm, it should surpass in brightness any 8x42 made. Also, something that is increasingly important to me, in bright daylight the reduced pupil of the eye will effectively stop the 8x50 down from its native focal ratio of about f/4 to about f/12, which reduces all aberrations by more than the same effect does in smaller exit-pupil binoculars. This effect has been remarked on by Henry Link regarding his 8x56 Zeiss FL, and I believe it is responsible for much of the high performance of my 7x50 Fujinon FMT-SX porro. I have been against ten power binoculars since I first started birding, but the 32mm Ultravids are very easy to hold steady, even though, when I first tested them, they seemed too small for my hands. But birding in Arizona especially convinced me that I needed more power; there were too many times when I wished I could see just a little more detail to positively ID a bird (and the wide open spaces in the desert allow for much more long distance birding than here in Michigan). My 8x42 Trinovids were my main binoculars for many years, but on some days they are actually too bright - watching hawk migrations on clear days would give me a headache.

I’ll be quite interested to see if the new 8x50 Ultravid HD has less lateral color. I wouldn’t expect much improvement from a change in objective glass. Right now I consider the prime suspect to be the simple 4 element eyepiece used in the 8x50.

The most effective ones have indeed been proven to work. Prior to purchasing things, do some research on best 8x50 binoculars. Here are some questions to consider. Perhaps Leica should take an example from Zeiss and make a line of hunting binoculars with greaseless focusers for hunters (and owlers), and another line with grease for birders. The cheap ones have faster objectives and smaller eyepieces and prisms. It is ok for them to have more astigmatism in the outer field because they are used hand held. People pan around and bring the area of interest to the center.
