It depends what you are comparing. If you want the best image at under $500 the Chinese EDs are it. Really.
It does matter what you are comparing. I believe what you and others say of their image quality.
Well for what you pay for the top end glass there should be something in that league that separates the ZEN and others from the Swaro and others. I'm fully prepared to accept that there is. I am also fully prepared not to pay for whatever that difference is, because the difference is not worth the cost. I will grant that any of the alphas are likely more solid, better engineered and have better workmanship. I think they are for more likely to survive Peter Dunne bouncing them off of walls and such.
So it gets down to the simple fact that if you can afford an alpha glass, there is no reason not to. If you simply want to have the best instrument you can buy, there is no reason not to buy an alpha glass.
However the images of the "Chin Bins" is so good there is every reason to think the comparison will be made. The point is that for far less money you get a binocular that will likely give the average user plenty of service along with quality they can afford.
Good points made Steve and I'll not argue against any of them.
Let me try an analogy. A Chevy Malibu may accelerate faster than a Toyota Camry. It may even stop faster. These don't make it a better car.
Another car one... A Kia may be a great car if you keep it in a garage, maintain it well, and drive 5000 miles a year. If the car lives outside and gets driven 50,000 miles a year then the Camry might be the better choice.
For backyard birding and fair weather birding in the park, the Chin Bins might be great. Would you choose them for a once in a lifetime safari?
Swarovski takes the details seriously and builds them with an appreciation for the fine instruments they are, at a price granted. I was told recently by one of the owners of Scope City who is also an optical engineer that Swaro's process for annealing lenses take two years. TWO YEARS! Do the Chinese even anneal their lenses?
I'm pretty confident that the materials that Swaro uses won't decompose and turn to goo sometime in the future, or that a gear tooth won't break because it's made of good stuff and not pot metal or plastic, or that out gassing won't fog internal elements at some point, or that lubricants won't migrate into places they don't belong, or that lenses won't change shape after many heating and cooling cycles because they weren't properly annealed, or that they will maintain their waterproofness when it counts, and that someone could inherit them when I die and they won't be a piece of *&#@.
My comments were triggered by Matt Green's question:
I've been wondering if the Hawke frontier ED was good enough to beat the latest Swarovski SLC 8x30!
Of course, they are not.
