I have the older model 65 mm Razor HD and i like it very much. It is a very high quality scope. The only thing that i would make better would be a wider angle zoom eyepiece.
I took the eyepiece off my Swaro scope and i tried it on the Vortex scope. My zoom is the wide angle 20-50 WA lens. I fit it on the Vorext Razor 65 mm scope and it worked well.
I had 3 observations.
1. My Vortex Razor 65 mm scope is pretty darn good and the view through it's eyepiece is not all that narrow. Using the Swaro eyepiece did not make a visible difference in image quality or pleasantness. I switched back and forth between the Vortex and the Swaro eyepiece and i did not find any particular difference. This saved me a pretty penny, because i was considering purchasing the new zoom eyepiece from the new generation Vortex scopes, or even a new Swaro eyepiece for this scope. Because i do use the scope, i like it, it's angled, light, smooth, and i can use a smaller lighter tripod with it.
Instead of a new zoom, i found a relatively inexpensive Vortex 20x wide angle eyepiece for it and i like it. I got excellent wide angle views when i expect that i would need that (like scanning prairies or watching hawks)
2. The Swarovski eyepiece did fit and work on my Vortex scope, but it had a 2 mm play. The lens did not click tight and lock perfectly in the scope body. That worried me because it may no longer be a dust and waterproof fit. The bottom of the lenses have an O ring, i think, and when they are twisted and locked the seal closes the space between the scope and the lens. My fit was good, the lens was locked, but not tight.
3. Between the Vortex 65 mm with two lenses and two excellent tripods, and a wonderful small and light Nikon 50 mm ED with it's own small and steady tripod and two lenses, i have portability and comfort and optical performance and i get all i want from a scope 99.9% of the time. I find myself using the large Swaro less and less, like a couple of days per year maybe. I keep asking myself why i don't sell this scope?
