What make/model are you working with?@Pileatus, Thanks!
This is my first scope, and it is precisely the problem of gauging its performance in the field that I resorted to doing these measurements.
Clearly, the image quality (e.g., contrast, the sharpness feeling) at higher X is lower than what I can achieve at the basic zoom of 20X. The focus is snappier at 20X than it is at 60X. BUT these are things I have noticed with all scopes in store/outdoors, with the caveat that I haven't used them in the field as long as I have with mine. Not to mention those frequent hazy days, which makes concluding anything very hard.
Moving on to the Kowa 883, this time from the ATS65, I felt the relaxed feeling doubled/tripled! At this point, it became very clear that if comfortable viewing / easy eye positioning / FoV / brightness are of primary concern, it is hard to settle with 60/65mm scopes - whoever the manufacturer is! However, this drama in the view from the 883 comes with ~1.1lb weight increase, and >=$600 price increase over the ATS. It is thus very clear the 883 is too much for us to be traveling/hiking around with.
Or, now that you know what to look for, keep searching for that used cherry and get that...
