Choosing the right magnification for your desired uses is also extremely important as it affects the way a binocular performs in a whole host of different ways. Whilst there is a small amount of softening of the image on the periphery of the view, it is very minimal and was about the same as my controls and actually a little better than the Kowa 8x25 BD binoculars which is impressive. The theme of extreme high quality continues with the use of the same dielectric coated Schmidt-Pechan prism system that Maven use in their very high end, full sized B.1 and B.3 binoculars.Funny you should find the view through the 8x30 more 3D, I usually find the view through 7x binoculars has more depth, an enhanced sense of space that usually makes for an improved feeling of 3D (well, definitely not like a big Porro, obviously). It is not that often that I get a fairly uniquely designed binocular to review, so when the guys at MINOX asked me if I wanted to review their compact fixed focus BD 7x28 IF binoculars, with its open bridge design I was immediately interested. a b c Miller, David (2001).

Their maximum eye-relief of 15mm is pretty good and should be enough for most people who wear glasses.If you are going to be using your binoculars in less than ideal light conditions, at closer or extremely close ranges or need a very steady view.

The advantage of this is that it saves time by not having to focus on every object that you look at. The other main advantage is that because there are less moving parts, fixed focus binoculars tend to be more robust than traditional centrally focused binoculars. On the down side, their minimum focussing distance is very poor in comparison to most binoculars where you can make focussing adjustments. If you will be using your binoculars from an unsteady platform like a vehicle, boat or canoe – this is one of the main reasons why marine binoculars tend to have lower 7x magnifications. rifles, Excel Arms, Manufacturer of innovative weapon systems Ontario, CA X-SERIES PISTOL". 2023-06-14.

Retrieved 2023-06-14.The field of view for these 7x28 binoculars is 128m at 100m / 384ft at 1000 yards (7.3°) - which even considering that it has a smaller 7x magnification, is excellent. For example the Kowa 8x25 BD has a FOV of 331ft at 1000 yards, the Steiner 10.5x28 Wildlife Pro has is 264ft at 1000 yards, the Leica 10x25 Trinovid has a FOV of 273ft at 1000 yards and the Minox 10x25 BV BRW has a FOV of 290ft at 1000 yards. As you would expect with a fixed focus binocular the image sharpness varies. The closer you are to the binoculars hyperfocal distance, the better the image sharpness. Fuzziness was more noticeable when looking at closer images than looking at images in the distance.
