@Sarcophilus Harrisii: thanks for your extensive repsonse!
It has been a while since my last visit here, and I would like to thank you for all your responses!
Meanwhile I got my 2 rolls of 36 shots of slides developed. The shop did a good job: I got a slide projector from my dad and last weekend I displayed them. I was amazed by the quality; they are Agfa precisa 100 rolls, and although all shots are under-exposed, in most shots this is not hindering. Next time, I will add 1 or 2 stops. Shots look 3d, and sharp, and very nice for the eyes. Not sure if this is something subjective or objective, but to me, the slides are incomparable to high resolution printed digital photos. Maybe it is because I like the medium?
There are some drawbacks like putting the slides in the frames which I did myself, I damaged 1 because I used the Hamafix system which I had some difficulties with, so I used gloves and put the slides in the plastic frames by hand rather than the hama tool. Doing it by worked much better for me. I also unintentionally shuffled some slides, so I have to take more care when putting them into frames.
The only drawback of my Minolta camera is it's size: it is fairly big. And it feels cheap and plastic, but it is lightweight which is a plus. I do a lot of bicycle trips and holidays, so a small and compact camera makes sense. So that's why I am wondering if a rangefinder camera is something to consider. Also the idea of having one fast prime lens sounds interesting to me. I like the simplicity of having one focal length although I'm not sure if I will like it, as I always use my zoom lenses.
I'm wondering about your opinions about the idea of buying an analog rangefinder. I feel attracted to a secondhand leica, but maybe I'm just to much into looks and reputation. But I like the idea of a camera which is hand built (?), not far from where I live.
