Part of the problem is created by our online-selves, by promoting a wrong stereotype, namely that RFs and Teles don't go together.
Well, that's in fact one of those stereotypes which I find absolutely justified. I've been using 85, 90 and 135 lenses on a Leica with a 0.72x viewfinder for a while. I simply hated it. For some time I tried to force myself to like it, and eventually I gave up because it's such a squinty affair, with wildly inaccurate framing. I guess it's an acquired taste, like Marmite, fermented mare's milk or Visoflexes.
Eventually I went back to the SLR for everything longer than 50. Through-the-lens viewing hath its advantages and teles are one of them. A large image, faster portrait lenses, close focusing, and visually being able to put focus exactly where I want it made all the difference.
