Bright binos help

Postby ikillstuff on Thu Sep 30, 2010 6:03 pm

I am currently in the market for some new hunting binos. I own a pair of 12x42 steiner predators and the high zoom just kills the brightness in twilight hours. I am basically looking to upgrade to something that is going to hold brightness as it gets dark. Any suggestions are welcome but I am looking for 42mm objective lens at minimum and 7x zoom at a minimum. The new bushnell elite series is catching my eye. The 99.7% light transmission seems a little over the top but if anyone can verify that this is correct and holds true this will be the most likely choice for me. Thanks for any suggestions and help.

Hi

Do not read too much into light transmission numbers, since this is not a test that is standardized by manufacturers as to equipment used and technique used. At this time, the only published light figures that are in anyway useful are figures on binoculars subjected to the same test by the same tester at the same time and even, then, the figures can only tell you if one model is slightly better than the other. The figures should not be taken, literally. Then, too, the human eye is not capable of detecting differences of less than 3% in light transmission, anyway, so a model that scores 99% vesrus 97% for another is a moot point.

The biggest reason you are not getting the image brightness you want is, just as you have discovered the small exit pupil when using a 12x with a 40mm objective. Dropping down to any quality 7x42 or 8x42 with good lens coatings, like the Elite, will be an improvement and that, of course, assumes that your eyes can take advantage of the larger exit pupil. At my advanced age, for instance, the maximum exit pupil these old eyes can use is about 5 mm and that is only under totally dark conditions.

how do you feel about the brand meopta? They score high on everything and from what I hear they are a steal for the price.
