1 binoculars is about 800g, moderate weight.
2 on optics there are no questions, the picture is clear, light and even, without any lights and rainbow edges.
3 in the short-distance travel, it is good to carry it, in the long-distance travel it is better to take something smaller, for example, 8x42(500g).
4.it can be used in low light at night. When the light is too dark or completely dark, the low-light night vision telescope cannot see anything, you need Infrared night vision at that time.
1.HD zoom imaging. Continuous zooming can bring the magnified scene closer to a distance, Make the scene appear closer. The advantage of zooming is that it is convenient to zoom in, and the disadvantage is that the optical effect is weakened.
This zoom telescope has strict lens selection, more precise assembly and proofreading, improved focusing effect after zooming, and sharper imaging
2. The larger the objective lens, the clearer and brighter the image. 50MM(800g) is clearer than 42MM, lighter than 60MM(1000g). 50MM is a good balance, under the premise of ensuring clear imaging, reduce weight.
3 With the FMC green film, the image is clear and bright, and the color reproduction is more vivid
