It's been quite a while since the new version of the Diascopes and the new wide-range zoom eyepiece were introduced, and I reckon some folks have got a new Diascope and/or the new zoom by now. However, there are hardly any reports here, and I wonder why. Is there really nothing much to say about the Diascope and/or the new zoom?
I only had a chance to fool around with the new 85 with the zoom for an hour or so, not nearly enough time to come to any conclusion about their optical quality. My first impression was that the zoom is slightly better than the old 20-60x between 50x and 60x, with better contrast and slightly better resolution. This difference seemed me to be there even with the new zoom on an old silver Diascope. At magnifications above 60x the image wasn't quite as good; however, it was still quite useable. I also liked the new Diascope body, especially the armouring. Not sure about the focussing, however, that probably takes some getting used to.
