Firefield LM 10x42 Binoculars
Professional Optical Performance for Every Observer
The Firefield LM 10x42 binoculars represent an ideal combination of power and practicality for everyday observation. With 10x magnification and 42mm diameter objectives, these binoculars deliver clear, sharp images with excellent brightness. The compact dimensions of 142 x 96 x 56 mm and lightweight construction of only 425 grams make them perfect for extended observation sessions without fatigue. The ergonomic design ensures comfortable grip and easy handling during prolonged use.
Advanced Optical Technology
The optical quality of these binoculars is ensured through the use of BK7 prisms and fully multi-coated CL/FC/B,C/FBMC coatings on all glass surfaces. These advanced coatings minimize light loss and reflections, significantly improving contrast and sharpness of the observed image. The central focusing system with internal focusing mechanism allows for quick and precise sharpness adjustment, while diopter correction ranging from -4 to +8 on the eyepieces compensates for vision differences between eyes.
Superior Light Gathering Capability
The binoculars offer outstanding optical performance with a relative brightness of 17.64 and twilight index of 20.5, ensuring good visibility even in reduced light conditions. The 4.2mm exit pupil diameter is ideal for observation in daylight and twilight conditions. The field of view of 91 meters at 1000 meters distance allows comfortable tracking of moving objects and provides sufficiently wide coverage for terrain orientation.
User-Friendly Design Features
The Firefield LM binoculars are equipped with practical fold-down rubber eyecups that ensure comfortable observation for eyeglass wearers as well. The interpupillary distance is adjustable within the range of 48-75 mm, accommodating most users. IPX4 weather protection provides basic protection against weather conditions, making the binoculars suitable for outdoor use in various environments. The minimum focusing distance of just 2.1 meters enables observation of close objects.
