The Lens2scope 10mm 1:4 eyepiece is a small eyepiece/viewfinder unit that converts your telephoto lens to a spotting scope. Nikon made similar units back in the day that cost a fortune and never sold well, so I was slightly skeptical about the quality of the Lens2scope 10mm 1:4 eyepiece as it’ll only set me back $179.00. Was the eyepiece worth the modest price tag?
