Who the CL Curio 7x21 suits
The maker names birding and theater among its uses. The 16 mm eye relief suits eyeglass wearers, and the 8.9 oz weight suits a long day on foot.
The 21 mm lens gives a calculated 3 mm exit pupil and a twilight factor of 12.1, so it gathers little light at dusk.
CL Curio 7x21 can be set against the most popular models of every size in the best binoculars list. Swarovski lists it in the $500 to $1,000 price band, alongside the models in best binoculars under $1,000.
