Hello Folks,

First post here so I'm definitely a NEWBIE!

I've exhausted the search button and yet find myself compelled to bother you with what you will probably consider a "simple" question (read, I'm too stupid to understand much of the information postedLoco).

I have an appreciation for quality optics but unfortunately not the budget...through sheer luck and a little preparation I've been fortunate to collect a few quality pieces in addition to the more common stuff.  My deer rifle wears an 3 X 12 X 56 Swarovski, my AR a Zeiss Conquest 3.5 X 10 and the rest of my rifles are outfitted with various Leupolds...so I think for the most part I'm in OK shape there.

My question relates more to binoculars.  I have an older pair of 10 X 50 Burris Signature Series binos that I leave in my truck and have a pair of 8 X 32 Kahles (from the Sample List) for turkey hunting and sitting in a tree stand.

Here's the rub...I ran across a SMOKING deal on a like new pair of Swarovski 8 X 30 SLCs yesterday so I had to pick them up.  I "can" steal enough $$ from my slush fund to cover the expense but I'd prefer to sell something in order to not have to (make sense?).

I can probably get almost enough out of either the Burris or Kahles to cover my recent find...but I'm having trouble doing so...but if pressed I'd probably let go of the 10 X 50's...

Here's the crux of my question...will the smaller objective of the Swaros but with the added advantage of the "brighter" coatings gather as much light as the Burris?   If so, I'll probably send the larger, older ones down the road...my intended us of my truck binos is scouting deer in the evenings/dusk.

OR, should I just keep them all and have a "good problem" on my hands?

Thanks much for any input you can provide.

Jeff

Here is my hunting partner. This baby will be better than your Burris and Kahles combined.
 
In fact, the SLC series seems to have coatings optimized for low light. They offer excellent contrast at dusk and dawn or in clody and misty weather. They also cut glare from snow and sunshine extremely well, and work like a dream on backlit objects. This is a binocular that will serve you forever, for whatever you want. I have never whished that it had better coatings, brighter optics, or anything of that sort. I did sometimes whish for the focuser to be at the ocular end of the bridge, for faster focusing on small birds, but that is of no consequence for hunting. I have an EL 8x32 for that. No, they are not optically identical.

Glass type, grinding, coating, design, manufacturing tollerance and quality control has a lot to do with the answer you want to hear.

I have owned Burris Products and they are good. But in my experience and IMO I would not put Burris anywhere near par with the Swaro in glass or coating.  Though I do believe the Burris will be brighter due to a larger lens. I would expect like a larger camera lens with big glass but a poor coating the Burris brightness response to be bright but not nearly as linear the closer it came to resolving whites / highlights.
 
IMO if you find the Burris lacking and can answer a need get the Swaro and if you just have an itch for a new bino I would wait for a used Ziess FL or Leica Ultravid HD to pop up.

Burris Signature 10x50 has an exit pupil of 5mm
Swarovski SLC 8x30 has an exit pupil of 3.75mm
 
There is no substitute for exit pupil, coating can close the gap but not a 1.25mm one.  If your 10x50's were low end tasco, then the Swaro would be brighter but we're talking about a Signature here and they are above average binos.
 
The 8x30 will have a wider field of view.  Typically I would recommend an 8x30 if you would be using the binos to find something but not really evaluate it.  IE:  An 8x30 is great for scanning tons of real-estate like on an elk or mule deer hunt, then once you find one you would put the spotting scope on them for evaluation.
 
The 10x50 is a great binocular for stand hunting and counting points.  Not the best low light numbers but still acceptable.  The extra magnification is sometimes more beneficial than the extra light transmission you would have if using an 8x56.

Jeff,

No. Do yourself a favor and compare the two binocs, side by side, at dawn and dusk. SEE for yourself.

Thanks, all for the replies and insight...

So, in layman's terms...the Burris will likely be "brighter" but the Swarovski will probably have better "quality" of image...

I think that I can swallow that...

I picked them up...just too good of a deal to pass-or so I thought...so for now I have 3 pair...I'm sure that I can find a use for all of them.Big%20Grin

Tonight, at sunset and every 5 minutes thereafter, look into the shadow of a backlit object. Say, a patch of woods with the sun behind them, or a barn with the sun behind it, of just the shadow of a bush with the sun behind it.
