Ok, I think I'm getting close to picking here.  I'm looking for a hunting binocular which I can also use for general wildlife viewing.


Is a 7x50 or an 8x42 going to give better low light performance?


Both are:


porro prism

fully muti coated


1.  Steiner 7x50 Police

2.  Swift 8x42 Ultra Light Porro or 8.5x44 Audubon


Also, if I were to throw in a 7x50 Steiner Military R, how much better would they be?

According to Steiner's specification sheet the 7x50 Military & Police models are identical.
The 7x50 will give you the best low light performance. Are you aware that the M & P are both IF (individual focusing)?
The Steiner's are better for hunting.

The Audubon has a wider FOV 430' vs. 354' for the M & P.
The Audubon is lighter 24.6 vs. 37 ozs.
The Audubon ED 8.5x44 would be better still, but cost about $150 more than the non-ED.

I can't really comment about the Steiners in question because I have not looked through those models. In therory with a 50mm binocular objective you should get better low light performance (glass being equal) I will say that my Swifts Audubon 8.5x44 pull in a good deal amout of light.


I'm no optics expert so I'll give you my backyard joe experiment.  If I go outside in the evening well after the sun has set 830 pm and with minimal street lights in the area (not near the house) I am able to look over at a neighbors chimney about 60 yards away which is completely blacked out to the naked eye and with the Swifts I am able to see individual bricks as well as the mortor between the bricks.


The only complaint I personally have is I wished they were 10x for the type of hunting I do.  Also while it does not effect me since I dont wear eye glasses (Yet) people that do will notice that the Swift Audubon have a pretty short amount of eye relief..other than that great glass.


I have both the ED pair for myself and the non=ED bought for my dad. During normal daylight hunting hours the non-ed's appear a bit brighter (atleast to me and dad and hunting friend) then my ED pair.  In the evening or in low light there really is not any difference.  The ED glass really does eliminate the chromatic purple haze you may see while looking at say a bright object .  Some people are not sensative to this my dad for instance it does not bother him, me it drives me nuts so I really like the ED glass.


  I have a pair of Weaver Grand Slam 10x45 fantastic glass unless your looking at high contrast bright objects or if your hunting around snow when the sun breaks then the Chromatic  aberration is quite visible. I noticed it quite a bit with a pair of Pentax SP's as well, but like I said I am sensitive to it. If you are then the ED Swifts are the way to fly, if not the regular model is very good, clear and bright and $150 cheaper.


Good luck
