I've considered the premise of this thread for a while, about cameras which make you feel that the image they're making is somehow more permanent or meaningful. I think my experience has been that it's mostly either larger/heavier/more "pro" level cameras, and/or ones which have more process involved in shooting. In both cases, it feels like there's more "going into" the picture than there is with lighter, smaller, more consumer-oriented cameras.
But I also think it's my relation to the camera, the way I think about it, which mostly causes this. I definitely had that feel with my Pentax K-1 II. It's heavy, it's pretty much pro-grade, the flagship (and only) Pentax FF DSLR. The sensor makes beautiful images. Pair it with a good lens and you almost have to try to take a bad photo... but here's the thing: I've owned it for a long while and I've shot loosey-goosey with it, I've shot all sorts of things, I've tried things that definitely haven't worked. The feeling has therefore dissipated, a little.
I guess the spark is still there, though. More in the sense like I'd rather pick this camera up and take a meaningful, permanent shot with it. So, in that way, it's still conducive to that feeling. Just a little less keen than when it was newer to me.
