The first number you see on the binoculars is the magnification, while the second represents the effective objective lens diameter. So 4, in the case of 4×30, represents the magnification which is the number of times the optical gadget enlarges your desired sight of view, which means that while using 4×30 binoculars, you will be able to see the view four times magnified as compared to the one seen by the unaided eye. Effective lens diameter or objective lens diameter is the second number written on the binoculars, like 30 in this case, which shows the size of the aperture, which controls the amount of light transmitted.

Eye relief is the optimum distance between your eyes and the eyepiece of the binoculars, and it is a crucial consideration for eyeglass wearers. More precisely, it is the distance from the eyepiece lens’s outer surface to the point where the exit pupil is formed. The viewer can only grasp the whole essence of the picture if his eye is within this distance, therefore it is better to go for good eye relief binoculars.

Age Verification

Wide field of view (Vary from binoculars to binoculars depending upon the particular brand manufacturing the binoculars) The binocular lens coatings mostly add to the light transmitted through the lens. Hence increases the brightness, saturation, and contrast of images with better color reproduction and color fidelity, where contrast means the difference in luminance between adjacent bright and murky areas. The higher the contrast is, the sharper and more brilliant the imaging is perceived to be. It will help if you look for fully multi-coated lenses, as they have several coatings on all air-to-glass surfaces with different refractive indices. The fully multi-coated optics being on the high-end ensures the amount of reflected light to its lowest. At the same time, it considerably increases the optical performance and ensures impressive low-light performance. Last but not least, the fully multi-coated lens also guarantees the absence of any chromatic aberration. Eye Relief These are a fairly unique pair of binos in today s market. The low magnification - in reality about 3.5x combined with a wide field and acceptable levels of field curvature are not obtainable elsewhere. I have used them a couple of times for operas where the stage is too far away to see any features on singers faces - they bring it close enough to really get involved you see the emotions and feel close up but you still see enough of the stage to get the overall production. Normal opera glasses and small magnification binos may be sharper at the edges but either they don t magnify enough or you can lose the sense of what is going on as things are happening outside of your field of view. It s a shame they don t have individual focusing eyepieces or diopter adjustment but for the price that s OK. Until pentax or someone steps in with a premium product these are worth every penny.
