I'd love to see a waterproof SE (how did people manage without waterproof porros in the past?). Or a 820 with real full field ER. Or Pentax porros with ED and a better FOV.But the Swift 820ED have their own problems. Eye relief. It's speced at 17mm but it's perhaps 12mm usable ER. Not enough for the aging eyeglass wearing bino buyers (which are the majority today). I suspect that either the design of roofs have decoupled the focusing from the eyepieces has results in some freedom to make eyepieces with much better ER than porros had. Or perhaps the older porro makers didn't care about ER and the roof makers did. But the consumers cared. So this would be a demographic change in birders driving the shift from porros to roofs. And the less innovative porro makers didn't see this coming?There's no conning involved. People bought on features they liked and the market evolved.This all brings to mind the "The Innovator's Dilemma". This sort of change is not going to be made by someone already in the business because to make that change would destroy very profitable parts of their market.<a href="http://en.wikipedia.org/wiki/Disruptive_technology" target="_blank">http://en.wikipedia.org/wiki/Disruptive_technology</a>Perhaps we'll see a range of (Chinese made) Kansas Bird Ranch porro bins in the near future? You can offer them the features they want (see above) in a porro for a lower price. They should flock to them!</blockquote>
