Nikon Aculon T11 8-24x25 Zoom Binoculars 8 to 24x 25 mm Front Lens Diameter

Product Information

At 8x Magnification: All binoculars with an 8x magnification and 25mm objective lenses have an Exit Pupil of 3.13 (25/8) and a Twilight Factor of 14.1, which if you compare them to a full size 8x42 binocular, which has an exit pupil of 5.25 and a twilight factor of 18.3, it shows that the increased objective lens diameter of the 8x42 binoculars will gather more light and make it possible for the binoculars to transmit more light to your eyes. This is the main compromise to using a compact over a larger pair of optics, but having said that in reasonably good lighting conditions like during the day, where your eye pupil size is only about 2 to 3mm, this will not be much of a factor, it is just at twilight and under poor light where you can really notice the difference. You must also remember that having a good pair of compacts even in poor light is still much better than having no binoculars at all! centimeters = inches / 0.393701 Using our inches to centimeters converter you can get answers to questions like: Just before we get into the detail of analysing the price of this product, we want to briefly highlight the importance of setting yourself a budget before you spend too much time shopping around for a suitable product. It’s all too often that we get carried away when shopping and find ourselves buying a fantastic product, but probably actually overdelivers on what we need and therefore costs a lot more than we should have spent. So spend a bit of time looking around at the sort of price you can expect to pay for products in the Binoculars category and use that alongside your own financial situation to set yourself a budget.

As you would expect, keeping the image nice and still becomes harder and harder as you increase the magnification settings. At 24x I was able to the image still enough to take in all the details of what I was looking, but I had to concentrate on staying very still as even the smallest movement has a big impact on the amount of image shake. This is fine for short bursts, when you just want to take in a bit of detail, but is definitely not something that you would want to do over longer periods. Weak points? Their very narrow field of view, even at 8x magnification is really noticeable and their rather distant minimum focusing distance are definite weak points. The amount of eye-relief will also be disappointing to those of you who want to use them with glasses on. The fact that they are neither water or fogproof is also a shame, especially for those that like to use their optics in all weather conditions. At 16x Magnification:When you increase their magnification to 16x their Exit Pupil reduces to 1.56 (25/16) which means that even less light will be getting to your eyes. Of the 54 products, 17 were more expensive and 33 were cheaper than NIKON Aculon T11 8-24 x 25 mm Binoculars. Prices from NikonAt 24x Magnification:When you increased to their maximum level of 24x the Exit Pupil reduces to just over 1 (25/24) which means that not a lot of light that enters the binocular will reach your eyes. Whenever we shop for Binoculars it’s important to consider the quality of the product. Typically we’d break down quality into a few factors, use these when deciding if NIKON Aculon T11 8-24 x 25 mm Binoculars is right for you. These are quite hard parameters to judge and very subjective, but I thought that the contrast of the image produced was good and once you have correctly focussed on an object the image is pin sharp. Weight and especially size really matter in a good pair of compacts and obviously we are looking for a pair that is as small and lightweight as possible. This is because if the "compact" pair is too large to suit your specific requirements, you may as well just go and get yourself a similar quality mid or full sized pair of optics that by their very design will usually perform better, especially in low light conditions: I doubt if this very thin rubber armouring would protect the optics very much from damage, but it does make a nice grippy surface to hold onto and is well placed for this.

More information on quality can be found in this old but still very helpful article from Harvard Business Review. Ideal Uses: Like most compact binoculars, these are pretty good if you are looking for a take anywhere pair of binoculars, perfect for camping... although not if you are going to get them wet! I would take them hiking with me, if spotting birds and wildlife was not my main focus as they are let down by their poor field of view. I also see them sitting in the cubbyhole of my car, or in my golf or kit bag to be used at any time. I think where they may be ideal is at a sporting event, where you can use the zoom to take in some details on the field, although once again a wider field of view would have really been appreciated here. At 12x Magnification:When you increase the magnification on these Eagleviews to 12x their Exit Pupil reduces to 2.08 (25/12) which means that less gets to your eyes.Once you’ve completed your list of brands you’d be happy to buy from, use these filters and also filter by a price within your budget and you may find that you’re getting much closer to finding the perfect Binoculars for you.

Brand is again something that you should really put some thought into when buying any product, but especially so for Binoculars. There will of course be some recognised brands that offer better products and brands that you know you can rely on to provide a great product, time after time. Thankfully Nikon is one of those brands.When set to a magnification level of 8x, their field of view is 80m at 100m / 240ft at 1000 yards (4.6°) - which, for a what at this setting effectively an 8x25 binocular is not very good. To put this into context, the Steiner 8.5x26 Wildlife Pro has a FOV of 333ft at 1000 yards and the Kowa 8x25 BD has a FOV of 331ft at 1000 yards and even the Minox 10x25 BV BRW which has a magnification of 10x has a FOV of 290ft at 1000 yards.
