If anything, RFF has had the opposite effect on me: seeing people get excited over lenses I've no desire to try, and cameras I tried years ago and found indifferent.
There's less and less that I want. In my 20s I was always trying new (old) stuff, but it's slowed down a lot over the decades. Nowadays there has to be a REALLY CONVINCING reason to want to try anything new, and I've very little desire to try old stuff because mostly, I've already tried it and been more or less unimpressed. Even the good old stuff like the Konica SIII is not as much use, to me, for taking pictures, as my M-mount cameras and lenses.
In other words, I prefer taking pictures, rather than getting used to new (or old) cameras. And I prefer taking pictures with equipment I don't have to think too hard about using, be it an M2, an M9 or a 13x18cm Technika.
Probably just old age. Been there; done that; not interested any more. But I'll add that not spending money on stuff I 'can afford' means that when the time comes, I've more money for the stuff I really do want.
Cheers,
R.
