I get along quite well with my Leupold BX-3 Mojave's. I'm sure they aren't really comparable to swaro's, but I personally decided to put more money into a better scope because it is what will make or break you when it comes down to it(I wish I could have justified both
). As far as your eyecup problem I won't be much help as I wear glasses. I actually came across the receipt from my bino's today and seen I got them on sale for $329 (10x50).
That's backwards. Can't shoot animals if you can't find them. Only time you look through your scope is to shoot. Any decent $300-$500 scope will hold zero, give a clear sight picture, and make true adjustments. What else do you need???
But binoculars in that same price range will never even come close to helping you see animals like you will with high end alpha glass. I also guarantee if you sat with your eyes in those Leupold's for an hour straight, you will have a pounding headache later on from eye strain.
Alpha glass allows you to clearly view longer distances in all lighting conditions for much longer periods of time with no eye strain.
I have a perfect example of the difference in glass quality from the last time I went hunting with my father. We were hunting antelope on the plains when I spotted some animals moving about 1500-2000 yards out. He had a set of 12x42 Nikon Monarchs, and I had a set of 10x42 Vortex Razor HD's so he already had me beat on the magnification end, but not even close to the clarity I had. The conversation while viewing the animals went exactly like this;
Me: "Look, there's something moving out there"
Dad (gets his binos up first): "Oh yeah, looks like antelope"
Me (looking through my binos now): "No Dad, those are deer, just hard to tell with the sun behind them"
Dad: "Are you sure?....Oh I suppose they are deer because they are pretty big, must be mule deer"
Me: "Maybe...No those are Whitetail deer, do you see the one facing away from us with the big white outline on it's tail?
Dad: "No"
Me: "Well it's a whitetail for sure...Oh look, they are starting to run, something must have spooked them, now we should be able to see if there are any bucks in the group"
Dad (after all deer came into view again): "Looks like a bunch of does"
Me (scanning from front deer to back as they were running): "No, that third one is a little buck...3X3 Dad. Oh and there's a nicer one, really short tines, but looks like at least a 4X4."
Dad: "I don't see the antlers, are you sure?"
Me: "Dead positive Dad. Watch them as they come closer and you'll see what I'm talking about"
Dad (As deer continued to run angling towards us and to the left): "Still don't see it.........Oh wait...Now I do. Man, you could see all those antlers way out there into the sun? Tell me again what kind of binoculars you are using?"
The deer had covered about 500 yards distance closer to us before he could make out with 12X what I could clearly see much further with 10X. HUGE difference and it was all solely due to glass quality.
If my Dad would have wanted to shoot one, he would not have had time to get set up by the time he figured out there were bucks in the group because they were gone soon after he finally saw them. With my glass, I identified the bucks and species right away and would have had plenty of time to get into position if they had been something I wanted to shoot.
But most folks never know there is that much difference until they use alpha glass in the field. But I do know that you will NEVER find a hunter that has owned alpha glass going back to using the cheaper glass. And to think, my Vortex Razor HD's are not even close to as good as the new Swaro EL Swarovision glass, yet I still had that much of an advantage over my father's mid-priced glass.
Buy once, cry once. You'll never regret it. I used cheap glass for a long time before I bought a good set of binos and I wholeheartedly regret every single hard earned penny I wasted on the cheap stuff.
