Remarks:

Like all of Nikon’s Action EX models – porro binoculars currently in the configurations 7×35, 7×50, 8×40, 10×50, 12×50 and 16×50 – this 8×40 offers good value for its price: nice field of view, quite good central sharpness, acceptable edge sharpness, waterproof design. The Action EX models are among the best lower middle class binoculars on the market.
