    I had two pairs of bins that grew legs (grrr) so I needed to replace them. Based on specs I had a hard time deciding what to get — I wear glasses and use mine for sporting events, light bird watching, hikes, and keeping an eye on my livestock. I ordered this and the Bushnell Legend L 8×42. Although they are really so comparable the decision was tough, I will be keeping the Bushnells.These bins supposedly had better glass (dielectric high-reflective Multilayer Prism coating which is only available on the Bushnell M version) but the images were nearly identical. Quite often I felt the bushnells were sharper. Both did well in high direct sun, indirect light, dusk and at night for moon looking. Both have weather and fog protection. This has better eye relief but the Bushnells were adequate. In the end the decision came down to the little details. These are heavier and take up more space. The Bushnells have a locking dioptic adjuster (it is a bit hard to operate but it’s there). They also were easier/faster to bring into focus. Lastly the protective caps on the Bushnells are just better — the wide ends are attached to the bins and the narrow ones are loose but easy to remove yet stay while in your case. The Nikons were all loose, popped off when I pulled my bins from the case or refused to come off based on humidity, and the eye piece covers were very hard to get on and off.It was a decision that literally took me weeks but in the end it was the little details that made the difference. To be honest, if I had the funds I would have kept them both.

    Nikon is known for making exceptional quality lenses, and these binoculars are no exception. The image is crystal clear and you can see far enough away for bird watching or whatever else you are doing. I used these in eastern Africa while embedded with an anti-poaching unit and they worked well for surveillance purposes, allowing me to spot threats from a distance on several occasions. I could see well enough to ascertain whether the individuals were armed, which was pretty important in the context.Pros:- Rugged! Survived a year of being hauled around Africa and banged around in the mud, rain, high-humidity, and fine red dust that can work its way into almost anything but never compromised the lenses. Hard to destroy these binoculars, short of a drop directly lens-first onto a rock.- Great clarity, good distance, wide field of vision. These are a good compromise between distance and visual field, allowing you to clearly see things that are quite a distance away without getting the tunnel vision that higher levels of zoom bring on.- Price. Don’t know if you could find a better all-around pair of binoculars for the priceCons:- Heavy and bulky. If you are an ultralight traveler then these are not the binos for you. When in their soft case, they take about roughly the same amount of space as a metal lunchbox.If you are okay carrying the extra weight around, and have enough room in your pack to fit them, then these are a really excellent choice.

    I currently have over 10 pairs of binoculars going back to the 80’s(including my original pair of Nikon Travelite 9×25 compact binos). The two pair of Nikon Monarchs that I own are great roof prisms with the Monarch3 8×36 being my favorite compact roof prism vs the slightly bulkier/heavier Monarch5 10×42(which is still a great bino!) The Nikon Trailblazer 10×50 roof prism is a good tough bino but not quite the same caliber as the Monarchs so I rarely use them now. I originally bought the Nikon Action porro prism zoom 10-22×50 which impressed me so much as to the lens and build quality for the money spent that I decided to buy the these Action Extreme 8×40 binos that I am now reviewing. First off these Action Extreme binos are as apparently indestructible as you can get; fogproof, waterproof, rubber armored, super easy fast focus, clear crisp image,wide field of view and very comfortable and natural in the hands. They are of much better build quality than the plain Action 8×30 binos and are worth the extra few $$ spent in my opinion. Being as how the Action Extreme binos are built like an armored battle tank their only drawback is the slightly heavier weight(which also helps stabilize the image)and they have a very very slightly fuzzy view at the outside picture edge that you don’t really notice(unless you are looking for it)but given the fact that the really wide field of view offsets this…and for the low price and high build quality these are truly great “all around” binocular bargains. If you want another great bargain check out the Leupold Yosemite 6×30 or 8×30 binos, I own both of these two Yosemite binos and the glass and image quality are amazing and at half the weight of the Nikon Action Extreme and at a great price point. However the build quality of the Yosemite binos is not as impressive as the “tanklike” easy handling, very smooth easy focusing Nikon Action Extreme 8×40 binoculars. One last thing after having used both roof prism and porro prism binos is that I find that the porro prism provides a crisper, cleaner wider image and are easier on the eyes for more extended periods of time versus the roof prisms(if you get a roof prism Do Not buy a cheap pair,you will regret it). And if you stick with quality binos from the likes of Nikon or Leupold you can’t go wrong. Also the porro prism binos cost considerably less than roof prisms(the only real advantage of roofs are their more compact size). This is a kinda long review but I hope my extended side by side matchups of these best selling binos help you in your buying decision….Happy Glassing!!!

    Fantastically clear. They seem to be durable, having survived a 4-5 foot fall.One aspect that I noticed as being clearly superior to other designs, is that the diopter adjustment is not affected by contact with your eye socket. Thus, frequent readjustments are not needed.I would love to see the eye rests be more resistant to being pushed in, so that I might push them against my eye sockets more firmly for increased stability. Having them be softer would help with comfort while doing this, although I wouldn’t want to sacrifice my ability to gain stability.Picture for scaleAnyway, these are great, and nearly everyone that tries them remarks at how clear they are. Highly recommended.

    We have two pairs of these binoculars, I use them for work and wildlife watching. Easy to use, excellent optics and have taken some rough treatment. I compared them with a friends Swarowski`s and I cant tell the difference. In fact I preferred these to handle and use. Easy to use single handed too.

    Buscaba unos prismáticos para observación astronómica y diurna pero que se pudiesen llevar en mano y he ido probando unos APM ED Magnesium 10×50, Nikon Action EX 7×50, unos Nikon Action EX 8×40 y unos Nikon Aculon Zoom 10-22×50.Los APM 10×50 los encontré muy pesados (pesan 1.3 kg los APM) pero sobretodo esos 10 aumentos a pulso son muy difíciles de mantener para la observación astronómica (aunque de día se llevan bien), y no os engañéis si queréis ver algo con detalle necesitareis estabilidad (osea un trípode) así que los descarte para llevarlos a pulso. Como curiosidad añadiré que en el APM ED Magnesium 10×50 todas las correcciones de color y aberraciones virtualmente no existen, el campo es plano, la transmisión de color es perfecta y el efecto túnel es mínimo. Juega claramente en una liga superior a la de la linea Nikon Action ex. Una pena que no tengan binoculares 7×35 u 8×40.Como no estaba cómodo con los 10 aumentos para llevar a pulso, llegue a la conclusion de que era mejor usar menos aumentos. Así que compré los Nikon Action ex 7×50. Esos siete aumentos lo hacen extremadamente estable, a nada que tengas pulso lo aguantas sin problema, ese kilo igual te cansa pero solo si lo llevas mucho rato.El “problema” de este binocular es que pide muchísima pupila (7mm para una apertura de 50mm y 7 aumentos, algo solo para gente joven y con buenos cielos de noche). Y es que es mas aprovechable una apertura en combinaciones que piden 5mm de pupila ademas de añadir mas contraste (10×50, 8×40, 7×35). Otra cosa que no me convencía mucho es que solo 7 aumentos me parecían pocos, quería usarlos también de día para ver alguna cosa lejana (me han gustado mucho para eso), y como había leído mucho y bueno sobre los 8×40 me decidí a hacer el cambio.Los Nikon Action Ex 8×40 al probarlos de noche me sorprendieron muy a bien, creo que he visto más estrellas entorno al cinturón de Orion que con los 7×50 por ejemplo, o al menos deben ir muy peleados.En cambio de noche con unos Nikon Zoom Aculon 10-22×50 esa apertura y pupila hacen que se vean mayores detalles por ejemplo en Orion y los cúmulos abiertos grandes como las Pléyades, Hyades o el Joyero. Aunque es difícil mantenerlos a pulso.Los 8×40 Ex, son más ligeros (no mucho, lo que pesa de verdad es el cuerpo del binocular y eso no cambia), y compactos que los 7×50. Los 8x aumentos sobre los 7x puede parecer una insignificancia pero no lo es en absoluto, cuesta mas estabilizarlos, y de día disfruto bastante más que con los 7, vamos que se nota que te acercas mas.De noche con los 8×40 y en la ciudad he visto muchas estrellas en Orion, notado la nebulosidad, el doble cúmulo de perseo, un montonazo de estrellas en las pleyades, y hasta el núcleo de andrómeda con el disco algo débil. Unos 10×50 serían mejor en astronomía pero requieren un pulso que no tengo y pesan ya 1kg.Como “peros” señalaría que la definición en los bordes de este binocular es peor que en el 7×50 (creo que lleva lente asferica ese modelo), pero es solo relevante y molesta de verdad al 80-90% final. Esto puede solucionarse fácilmente al llevarse en mano ya que puedes cambiar a una posición mas central el campo de observación rápidamente. Otros problemas son: algo de mínimo cromatismo de día y otro poco de aberración esférica. Nada de esto es molesto de verdad pero lo señalo como algo que esta ahí y que no los hace perfectos. La perfección se paga (sobre unos 400 pavos pa arriba )En definitiva os aconsejo prismáticos que os den 5mm de pupila y que no os haga duelo bajar de apertura si vais a llevarlos a pulso. Si te da tembleque con un 8×40, no te cortes y busca unos 7×35: con esos aumentos y peso hasta un vejete los aguanta y esta cómodo.Si tenéis un pulso firme o pupila suficientes, entonces o unos típicos 10×50 o unos 7×50. Sin duda de noche vais a ver mas detalles al menos en astronomía.Ademas, oye, ahora tengo otra afición los domingos de irme por la ribera del río a mirar cisnes, patos y otras aves que pululan por ahí o ponerme en un sitio alto a observar algún objeto en la lejanía.Son muy buenos para seguir pájaros, tienen muy buen relieve ocular, para usarlos con gafas, buen contraste, y un gran campo de 8º aunque en los bordes sufre.Aconsejo comprarse un “cinturón táctico” para llevar la bolsa con los prismáticos que están a partir de 10 euros. (No, no lleva siquiera una correa cutre).

    Los prismáticos son en la línea de Nikon, buena calidad general y precio bastante ajustado para lo que ofrecen. La calidad de imagen muy buena en el centro, son muy, muy nítidos en el centro. Los bordes pierden bastante, a partir del 60 por ciento ya empieza a notarse, pero no es verdaderamente fuerte hasta las esquinas (donde nadie va a mirar en un uso normal). En un campo de visión de 8° y con este precio lo considero muy decente. La aberración cromática es bajísima, es de lo mejor que tienen, solo se ve bien en el borde extremo. El enfoque es bueno pero en los míos bastante duro, lo normal es que con el uso vaya cediendo. Son muy sólidos y pesan bastante, no son unos prismáticos ligeros de viaje, pero la calidad de imagen lo compensa. Para mí es mejor llevar estos que unos con prisma de techo mucho menos nítidos y brillantes… En general cumplen muy bien.

    Auf der Suche nach einem lichtstarken, griffigen, wasserdichten, kompakten, aber nicht zu leichtem Glas fiel meine Wahl auf das Nikon Action EX 8×40 CF. Das vielleicht vergleichbare Olympus EXWPI kostet mehr als das doppelte, hat aber auf Grund der Dachkantprisma-Konstruktion für mich klare Haptik-Nachteile (man muß mal beide Typen direkt vergleichen! Was nützt die kompaktere Bauart, wenn man das eine Glas nicht annähernd so ruhig halten kann!).Pro:-Lichtstärke-Sehfeld-Griffigkeit des Gehäuses-Fokussierring-Verstellung des Okularabstandes für Brillenträger-WASSERDICHT!Contra: (führte bei mir zur Rücksendung)-die Scharfstellung (Fokussierung) fällt ziemlich schwer (sehr schmaler Tiefenschärfebereich)-der “Okularring” ist derart groß, daß es mir sehr schwer fiel, den Augenabstand richtig einzustellen (da war immer die Nase im Weg!)Ich hatte mir zum Vergleich das (nicht wasserdichte) Olympus 8×42 EXPS I bestellt, welches diesbezüglich wesentlich angenehmer ist! (siehe meine Rezession zum Olympus)Auf Grund dieser Tatsache hab ich zu Gunsten der Haptik auf die Wasserdichtigkeit verzichtet.

    Se nota que no son unos prismáticos del montón. Extraordinaria definición. Lentes de muchísima calidad. Acabados impresionantes. Superficie gomosa, teóricamente impermeables y resistentes.
