Re: vortex binos
Below is the message I mentioned in my post above comparing the Zen Ray to the SLCneu. I have been reluctant to post this info anywhere since people might take it as Swaro bashing. I love my Swaro LRF and have nothing against them. I think the EL is the best bino for my eyes, but not my wallet. Anyway, someone might find this info useful.
I should point out that the first pair of ED2 got returned for a barrel out of focus. The replacement has been perfect. Charles is the owner of Zen Ray, and went out of his way to make sure I was happy with my purchase. Very honest and a great guy.

...I also wanted to let you know that I spent a few hours this afternoon and evening comparing the 7x36 ED2 vs the 8x30 SLC. I know its not fair to compare different magnifictions, or different objective sizes but still the differences were remarkable, at least with the samples I have. I thought you might be interested in my findings. I apologize if I don't use the proper optical terms, but here are my impressions.
In the late afternoon with bright sun I compared the two binos by looking at a tree that was backlit with bright sunshine. Glare, flare, stray light, whatever its called is one of my major concerns with any optic... bino, spotter, or riflescope. The Swaro produced very noticeable crescent shaped glare/flare in the lower 1/8-1/4 of the FOV. I tried to re-position my eyes with respect to the exit pupils, but this only made the glare shift to another area. I was not able to get a 100% glare/flare free view.
At first glance, the ED2 seemed to also have this glare, but I was able to reposition and eliminate the problem completely. While test driving the ED2 at your office, the first thing I looked towards was the sun and I did notice the glare. But, when I raised the SLC, it also had the same problem. For some reason it appears more noticeble with the SLC. Not necessarily bigger, but it stands out more. It was not until I got home that I noticed that the issue can be completely resolved with very minor repositioning on the ED2. Its actually quite easy. The same cannot be said for the SLC, at least for my eyeballs and the SLC sample I had.
I did notice that the ED2 seemed hazy with the intense light coming from behind and above the tree. I will need to re-test after cleaning the lenses in case there were some smears or smudges. Perhaps it has something to do with the large FOV which makes it appear as though its hazy, I don't know. Even so, the absence of the glare is a huge advantage for the ED2 in my opinion and there were no haziness issues noticed at any other time.
I was not able to test the binos with sunlight reflected off of water or snow and into the objective. This is something I would definitely like to compare.
I did position myself so that the sun cast bright sunshine over my right shoulder from behind me. The SLC had a very bright red star in the image. This was simply a reflection of the sun in the ocular, but the red star was fairly intense. Of course, one could reposition their body to block the sun or use their hand to provide shade but this still gave me an idea of how the ocular glass would handle reflections off of snow or water. The ED2 also had a star, but it was blue and not nearly as intense as the red star seen in the SLC. I could easily continue to use the ED2 with this reflection from the sun, but there was absolutely no way I could continue to use the SLC. I had to shade the ocular or rotate my body.
Depth of field seemed very similar between the SLC and ED2. There might be a difference, but since both seemed very good to me I didn't bother to compare them in great detail. In the mid to upper price range the DOF is generally very good. If they were lower priced binos, I would have compared DOF more.
The FOV is definitely larger with the ED2 but that is no surprise and one of the reasons I chose to buy one. Even at close distances, the huge FOV is impressive with the ED2.
In the evening the differences in light transmission were apparent in the very last minutes of light. For this test I used the shingles on the roof of a nearby house as a test grid pattern. The roof had several shades of grey shingles in fairly large block patterns. The edges of the blocks and different shades of grey could be easily seen with the ED2, but they appeared as grey blobs with little distinction between the shades with the SLC. The image was clearly brighter with the ED2, but it does have 36mm objectives (but is also much less expensive than the SLC).
I also looked at a pair of street lamps and found that the SLC produced more pronounced halos compared to the ED2.
Overall I would say that the 7x36 ED2 is simply a better bino vs the 8x30 SLC, at least in terms of what matters to me most... flare/glare control and low light capability. I also value DOF and FOV, but both seem very good at these. I was also impressed with the edge-to-edge sharpness, and sweet-spots for both models but tend to not focus on analyzing these things too much so long as they look good while I use the binos. I don't have a critical eye for CA or fringing and didn't set out to specifically look for it but I didn't notice it either. Someone else could probably do a better job of comparing color rendition. I thought the ED2 and SLC were equal and quite nice.
One thing that was consistent throughout my test was the fact that the ED2 was easier to focus. While the SLC seemed to take some fiddling to get the focus just right, the ED2 was a snap to focus. I think this may translate into less user fatigue with the ED2. Maybe the lower magnification helps the ED2 with focusing since its easier to maintain a steady image. I did not use a tripod, but did brace my arms and body for much of the test.
For me the ED2 is simply a more useful binocular especially under those tough light conditions. Of course this is a small test sample size, but still the differences are meaningful to me since I only want one pair of 7x or 8x right now. I would be very interested in seeing how the 7x36 ED2 compares to the 8x32 EL or a 7x Swaro/Leica/Zeiss.
So the bino harness came off of the SLC and is going on the ED2. I think the SLC will be returned to the dealer. I'm not keeping the ED2 because its just as good as the SLC for less money. That's not the case. The ED2 is simply a better binocular, at least to my eyes. I tried for several hours to find something that pointed in favor of the SLC. I couldn't find a single thing that the SLC did better. When you factor in the cost, it became a very easy decision. I was ready to keep the SLC, but not anymore. And I have money left over for something else.
Thanks again Charles. I wish you continued success with your company. You have good intentions and sincerely care for your customers. This is something that is lacking with many manufacturers.
