Product Information

Objective lens diameter – the measurement of the lenses at the end of the binoculars where light enters them (measured in millimetres). The larger the measurement, the more light the binoculars can take in, making the image appear brighter (all other factors being equal). Best binoculars for horse racing and other sports: Sports tend to happen during the day, so a bright objective lens is less of a concern. Something like an 8x30 will hit the spot, as the 8x magnification should be plenty to see what's going on from the stand. There's no point getting something big and heavy if you don't need it! All of Canon’s current range of binos have the ‘IS’ suffix in their model name to denote the fact they’re image-stabilized binoculars. This battery-operated option enables you to get a wobble-free image by just pressing a button on the binoculars – and the stabilizing effect is both instant and jaw-dropping. For the money and quality, most non-profits or struggling graduate students with an observational element to their project go with Eagle Optics, the company I feel has set the bar. The other common player we see at this table is Nikon, specifically their "Monarch" model. Perfect binoculars for every adventure: a great match for everyone from beginners to mid-range outdoors and birding enthusiasts. the perfect combination of premium build, portability, and price

Relative Brightness is the exit pupil squared. The relative brightness has no relation to how bright a pair of binoculars will be. The quality of the optics has more to do with the brightness of the binoculars than exit pupil size. Diopter is the adjustment that allows you to match your individual eye strength. This allows a sharp image in both barrels of the binoculars if you have eyes with differing clarity of vision. Note, only one side (or barrel) of the binocular has a diopter adjustment. To adjust your diopter, use the following instructions: Most have a central focusing wheel and a dioptre adjustment for focusing images. The dioptre adjustment is an important feature, as it only adjusts one lens and so compensates for when your eyes have slightly different prescriptions. The central focusing wheel adjusts both lenses simultaneously.
