Whether birdwatching or observing natural beauty, the highly developed apochromatic system with ED glass (particularly low dispersion) minimises colour fringing and ensures an exceptionally clear field of view. The field flattening lens system enables uniform sharpness right to the edge of the image. An optimised focusing system with adapted focusing speed - fine adjustment for distant subjects, coarser adjustment for close objects - enables precise control and natural handling. The Monarch Fieldscope is ideal for outdoor activities. It is waterproof and fogproof, robust and weatherproof. Supplied without eyepiece.
