The Victory HT / Conquest HD had what I perceived to be a more "natural" view. My thoughts thus far are that, while I definitely prefer the Victory HT over the Conquest HD, they are priced far enough apart and their performance is close enough that I'd consider the Conquest, due to value.
Before I purchase, though, I'd like to seriously consider the Swarovski SLC, but trying them out is not a possibility.
That's an interesting comment.
Not to be argumentative, but I see the exact opposite in my EL SV 10X42. I am constantly amazed by the fact that the view is exactly as if my eyeballs were moved to 10% of the distance to the object.
I see nothing "synthetic" whatsoever.
I GOL (gaffawed out loud) when I read this debate over which roofs have a more natural view, because regardless of edge sharpness I find that no roof has as natural a view as a porro. Diminish the 3-D effect and you diminish the naturalness of the view, because humans see in 3-D. If you're going to mimic a cyclops, you might as well use a spotting scope.
The other thing I GOL about was reading how some birders have not only come around to accepting a flat field view in a birding bin but they actually prefer it and think it's more "natural." When I first came on BF back in 1893 ("After the Gold Rush"), I expressed my preference for flat field views, having come to birding after using bins for stargazing (no one is more obsessed with edge sharpness than a binocular wielding amateur astronomer).
At that time, a lot of people thought field flatteners were unnecessary if not downright unnatural. Human eyesight is such that we don't see images sharp to the edge. If you look straight ahead, you will see a "zone of sharpness" (to borrow Stephen Ingraham's term) and an out of focus image in the periphery.
One BF member said something to the effect: You simply center the bird, my dear boy. (an oft quoted if somewhat embellished line)
The field of view of a human eye is 95° away from the nose, 60° toward the nose, 75° downward, and 60° upward, which gives humans an almost 180-degree forward-facing horizontal field of view, but of course, not all of that view in focus.
The FOV of binoculars is a lot less so I want as much of the image in focus as possible. I don't need a view that is totally sharp to the edge, particularly when smooth panning is sacrificed to achieve that, resulting in "rolling ball," an Absam ring and other Weird Science Funhouse Effects, which also happens when designers go to the opposite extreme and put in too much pincushion.
For me, a bin that balances pincushion with AMD and sharp edges with some field curvature (> 70% out) with gradual fall off toward the edges is more natural than one that goes to either extreme.
I found that the Swaro 10x42 SLC-HD to have the best balance of those qualities than any bin I've tried (except, of course, it lacked the more natural 3-D effect of a porro). I don't mean to set the SLC-HD as an absolute standard for everyone, because what's good for the goose may not be good for the gander, but for this "goose," it is the standard. YMMV (and will probably be less than EPA estimates, and way less than Kia's). :smoke:
