The new SFL 40s from Zeiss have arrived.

In late March of this year, Rich Moncrief from Zeiss provided us with an opportunity to try out examples of the new SFL (SmartFocus Lightweight) binoculars then in production. We were able to compare these new 40s with the Victory SF 42s and SF 32s. While both lighter and smaller, the optics of the SFL 40s compared very favorably with the top-end Victory SFs. Both the 8x40s and 10x 40s, at a list price of $1,799.99, cost about 35% less than the SFs. From now until Labor Day ( September 5, 2022) Buteo Books is pleased to offer a 15% discount on these superb new binoculars from Zeiss.
