Reviews & Ratings for Nikon Action Extreme 7x50mm Waterproof Porro Prism Binocular — 7 reviews — Page 1

Second time I've owned these. First pair didn't come back when I loaned them out. Built like a tank. Bright. I meean BRIGHT. I use them with a tripod for bird watching.Evening twilight seems like mid day. Too heavy to walk around with all day, but not the fault of the manufacturer. This much light gathering takes a lot of size and glass, and weight. You can find better binoculars than these but they will cost three or four times as much.

The Nikon Action extremes, especially in the bright, 7x50 configuration make for some of the nicest, clearest seeing optics you can ever buy anywhere near this pricepoint. Images are bright enough that even in very low light, if there is some residual star or moonlight you might be able to see large animals like deer in a field at a hundred yard distance or more. The low magnification keeps things very sharp and easy to manage for nautical purposes. I have even used them for astronomy to see Saturn's "ears", the Galilean satellites or wisps of the ring nebula as well as other double stars or just glassing the milky way but they are not great for it, just adequate. I also like the rugged construction in that the lenses are recessed very far back from the outer lips of the binos so that it's hard for things to get in and dirty or scratch them.

What is going on is that these binos use the bulkier Porro type prisms which are less expensive to manufacture than the straight through appearing roof prism binoculars. What this means is that usually, if two pairs of binoculars at the same pricepoint are compared, the porro prism binoculars that do not look straight like these will always be better. This means however that these binos are a bit on the bulky and heavy side. You can bring them on a hunt or long hike but the extra mass will weigh you down a bit. The main draback is the portability, if you need something more portable there are other options in roof prism types around this...

The exit pupil on these is around 7mm, which makes them great for night viewing. Kind of like 'poor man's night vision.'

Typical Nikon quality, great product, highly recommended.
Pros: Well made, great at night, clear image
Cons: A bit heavy, but that's to be expected

This is an excellent affordable outdoor binocular. Great light gathering makes it suitable in low light conditions. Adjustable eye cups allow use with or without glasses - a real plus for eyeglass wearers. Waterproof too. I highly recommend this item.
Pros: Reasonable price, waterproof, excellent light gathering
Cons: none

This is a great pair of binos! Very sharp & clear edge to edge. Great light gathering ability for low light viewing. These are FULL size binos so they are hand filling. Can't speak to waterproofness yet. Very satisfied so far. Lens caps should be tethered, case is low quality with no shoulder strap. These are my only gripes with the product.
Pros: Sharp & clear, Great light gathering ability for low light viewing.
Cons: Poor objective lens caps (should be tethered), low quality case with no shoulder strap.

It is a very good product for
construction and reliable optical performance under even extreme conditions.
It have an high Exit Pupil of 7.1 andperform extremely well in low-light conditions and are rugged enough for outdoor use in all climate conditions.
The price is very attractive .
