Well said Joe especially your last line there!
I went from a Swaro 65mm non-hd to a 65mm Swaro HD, then picked up a 85mm Zeiss 20-75X 3 years ago. I prefer it over the smaller swaros cause of the extra light and zoom. But I didn't initially like the extra bulk nor the extra 1.5 pounds over the Swaro. So I picked up a Vortex 50mm. Cute little guy and funny that the objective is the same size as one of my binocular objectives on my 12X50 Razor HDs
That said I rarely felt a time when I was reaching for the little vortex when I went to the field. The extra 3 pounds in the pack always seemed worth it cause I was nervous about giving up that 75X zoom.
If you are just looking for antlers on an animal inside 3 miles in most cases the 50mm Vortex is just what you need. If you are looking at counting tips and tines then likely you'll be disappointed Its a great little scope, just really comes down to your needs/expectations.
I bought a Nikon 50mm ED because my Swaro 80mm is big and heavy, but I do not think the Nikon has ever left my house for the reason Luke stated - it just doesn't do that much more than my binos.
