Lens2scope 10mm 1:4 Eyepiece for Canon EF/EF-S Lens, Straight View, White Color

Useful accessory to have in kit bag, to convert lens into spotting scope, saving weight and bulk of carrying both scope and camera. Optical quality good but no substitute for dedicated spotting scope. Note I would recommend removing the tripod mount, as it is very flimsy. Overall very good for price and intended function.l
