I have had and used a Fujica ST 901 since 1975. It came with a 50mm f/1.4. I soon added a 28mm f/3.5 and 135mm f/3.5, then a 50mm macro. All great lenses. I still use the Fuji 901 even though I have purchased two more as backups. But I haven't needed them and just exercise them once in a while. One of them came with the 43-75mm zoom. Nice lens, but not really my focal length. I once saw a person with the 75-150mm lens. Very compact and he said it produced great photos.
The lenses as far as I am concerned, take a back seat to nobody. Of course I say that not being an owner/user of Nikons, of Canons, and only a brief journey with a Minolta XG-1 because one became available. Still prefer my Fuji. I have also picked up a couple of Fujica ST 801 cameras. They are also great. I lent one to my daughter and she hasn't given it back yet. Nor do I want it. I am thrilled she likes it.
I have noted a lot of the older Fujica cameras on ebay. I have never used them, and don't think I would care to having used the 901 for so long. It is a bit heavy, but small. Just makes me think it is more robust. I really got it for two reasons; it uses all M42 lenses that I know of except for some of the Mamiya which can jam on the camera if you aren't careful of a tab on their lenses. I do have a contax 167mt with the Contax 50mm f/1.4 lens. It is really great as well, and I have never tested them against each other. Maybe afraid to?
I had also read a lot about the SBC exposure system. I love it! I used to really like available/low light photography. The 901 can't be beat. The SBC cells are more accurate in low light, and don't have the memory of other silicon cells. The 901 exposes automatically from EV -3 to EV 18. That is about 20 seconds to 1/1000. It sure worked well for me.
I also have a 35mm lens, but never use it. It came with something else. It just isn't a focal length that works for me. I like wider. I would love to have a 24mm and 19mm, but I have other lenses that are good enough, so I doubt I will ever spend the money for those lengths in a Fujinon SBC lens.
I would not get a Fujikor lens. You don't see them often anyway, and that seems to have been a lesser quality line, like Yashikor lenses. Useful if you get them cheap, but not in a class with the Fujinons.
I also have never been a fan of the later bayonet mount cameras and lenses. I don't think they had the quality of the earlier 801 or 901. YMMV.
