All about optics
The large field of view and optics providing edge-to-edge sharpness make the EL 8.5x42 binoculars versatile to use. The 4.9-mm exit pupils also produce bright images in poor light conditions.
Objective lens diameterThe objective lens diameter specifies how much light can enter the optics. This makes it a key factor in an instrument’s performance, for example, in twilight. The bigger the objective lens diameter, the more light the objective lens can capture. The darker the surroundings, the larger the objective lens diameter needs to be. Check the precise product name as the number after the ‘x’ specifies the objective lens diameter in millimeters. For example, a device with the suffix 10x42 has an objective lens with a diameter of 42 mm.
MagnificationThe magnification specifies the factor by which an object appears to be closer in comparison with the actual distance. The higher the magnification, the closer the object seems to be. However, a higher magnification also means a smaller field of view. Check the precise product name as the number in front of the ‘x’ specifies the magnification. For example, 10x42 is a device with 10x magnification.
Field of viewThe field of view describes the size of the image section that can be seen through the optics. This is specified either in meters (width) at a distance of 1000 meters (m/1000m), or feet (width) at a distance of 1000 yards (ft/1000 yds), or as an angle (degrees). The higher the magnification, the smaller the field of view.
Binoculars have a large field of view, which means you can see a wide area. Spotting scopes have a higher magnification, which makes the field of view much smaller, but you can see more detail.
Objective lens diameterThe objective lens diameter specifies how much light can enter the optics. This makes it a key factor in an instrument’s performance, for example, in twilight. The bigger the objective lens diameter, the more light the objective lens can capture. The darker the surroundings, the larger the objective lens diameter needs to be. Check the precise product name as the number after the ‘x’ specifies the objective lens diameter in millimeters. For example, a device with the suffix 10x42 has an objective lens with a diameter of 42 mm.
Shortest focusing distanceThe shortest focusing distance specifies how close an object needs to be to see it clearly with the optics. Between this value and infinity, it is possible to focus the image.
THE LEGEND
The large field of view and optics providing edge-to-edge sharpness make the EL 8.5x42 binoculars versatile to use. The 4.9-mm exit pupils also produce bright images in poor light conditions.
EL 8.5x42This is a first class product in my experience, backed by first class service. We bought these for our son after our own identical set from 2006 were repaired by Swarovski factory. Ours had been abused and had damage to an eyepiece and the focusing mechanism. Swarovski replaced parts and undertook a full refurbishment, only charging us for 1.5 hours labour (no charge for the parts). Not bad after nearly 30 years as we are not original owners having bought second hand from a camera shop in Cape Town, South Africa. Very grateful to all concerned.
By far the best compromise for lowland terrain. Incredible field of vision. And clarity, especially at dusk.
Great product. Nice and bright sharp images. These binoculars are well engineered for bird watching.
I have been using binoculars from various suppliers and Swarovski for some time now and have decided to buy an EL 8.5x42 WB as a leisure observer. The binoculars are very handy and I am more than satisfied with the sharpness of the optics and the quality. I can recommend this product to anyone. SG - Elmar.
