An extremely nice device, it is made of good materials: glass and metal. Everyhing work properly. Thank you very much.
optically is quitr good. and I'm comparing with my Leica. it's quite heavy. focus knot is a bit tight. like the eye cap design of rotating to extend or retract. At a fraction of Leica price, i don't really have much to say. hope it can last 5 to 10 years in the field
