I assume the Timber Rattlesnake was less than 4 feet long!I actually don't know the close focus distance of most of my binos. I know the SV's, the FL and the Zen Prime go real close. Just for yucks I once closed in on a Timber Rattlesnake with the Prime and it must have been about 4 feet. A truly cool view, but the snake was getting a little pissed off by that time. :t:
Last week I was watching Black-winged Damselflies at about 6 feet. Metallic green abdomens, black wings. Nice!
In general, I think 6 feet would suffice, but the new SV's at around 11 feet is a mistake.
I assume the Timber Rattlesnake was less than 4 feet long!I think in a case like that I would PREFER a longer focus.

Well, you know how they are: they coil up. Six feet is not uncommon.You have the Western Diamondback I guess. In my limited experience they take no prisoners, they will eat your binoculars. B![]()
That snake would have gagged on my Canon 10x42ISL's.
Plus I studiously avoided giving it a chance. o
It was really very pretty, coiled at the edge of a narrow dirt road.
We all were concerned for its well being and were happy to see it uncoil and glide off.
Proof perhaps that 3' focus is not always essential for nature observation, but I still think Swaro was wrong to cripple the EL close focus.
You don't need or want a binocular to view a rattle snake.
Back off........take care. Common sense prevails.

As beginning birders spend more time in the field, they begin to notice the other spectacles of nature. Try to study a Pygmy Blue butterfly, Blue Damsel damselfly, or small wildflower from 10'. I've had a MacGillivray's Warbler and a Sedge Wren hop across my feet and a Townsend's Warbler on my knee. You can get very close to birds if you do it right. Cutting that distance in half is a huge advantage. Most of the experienced birders I know study all of these critters. Beginning birding teachers know this and want to get their students into the best optics they can afford. Why would anyone buy an optic that is limiting when less limited optics with similar price and quality are available?Wow, interesting post. I really appreciate you sharing these perspectives. Many interesting points.
If I might ask for an explicit explanation, why doesn't 10' cut it for birding these days? Is it obsession over specs for their own sake, or are these beginning birding instructors concerned that their students get bins that will also serve well for other types of nature appreciation? If the former, we might lament that bino makers are feeling the pressure to spec close focus. If the latter, we might celebrate the increased awareness of how bins can bring us closer to nature in ways that are just as exciting and legitimate as traditional long-range uses (derived from hunting and military purposes). Magnified viewing of very small things at close range is a whole universe (between long-distance surveillance and hand-lens or pocket microscope viewing) that was sadly neglected in the history of optics. I'm glad that the category has finally been "invented". I wish the Papilio had some premium quality competition.
As a birder+butterflyer, I understand the value of close focus. I'm glad more bins are close focus capable, but I wonder why variable-ratio focus hasn't gone hand-in-hand with the close focus revolution. I think it would be revolutionary (in a revolution-reducing way!)!

it is the close focus to me that is separating the wheat from the chaff, not the FOV....
My thinking exactly.....Bins of quality or mid quality today have excellent optics, but it is the close focus to me that is separating the wheat from the chaff, not the FOV....
The people who always call for a short distance from binoculars should always keep in mind that ...
A: The optical performance of the binoculars is reduced, not just at the near point!
B: The focuser becomes more susceptible to defects and is therefore not as robust!
I have had three binoculars recently that have not been able to focus properly at close range.
The "W B" nomenclature (for wide field, eyeglass-friendly) has been around for a long time, often even labeled so, on SLC models as well. When it gets mentioned in the name seems purely arbitrary. The new EL42s are now called "Legend".The x32 models are just called EL 8x32 and EL 10x32, the x42 models appear to now be named EL 8.5x42 W B and EL 10x42 W B. The x50 models are similarly labeled W B. I do not recall details - did they use this naming scheme for the three sizes prior to this product line shakeup?
This point is of potential interest but there's no indication (and I did ask the Swaro rep here!) that the "Legend" optics have been re-optimized for better performance without the 1.5m close focus. So you still have the same "compromise", now without the close focus. What a deal. A real mistake IMO. (If they had just dropped the FieldPro kit that would have been great.)You ignored the optical compromises due to these extreme close-up ranges!
