These binoculars are equipped with an auto focus feature and an excellent balance of magnification and aperture. Designed for marine use, its classic 7×50 model provides an optimal balance of magnification and aperture.
Binoculars with increased magnification are harder to hold steady which may cause the image to appear blurry, whereas a smaller lens would decrease aperture, causing the image to appear darker.
This model features BK 7 prisms and extended eyecups that are useful for users with glasses.
