I like my J9 at all apertures, but I'm going blind, so don't trust me there.
Other glass in that neighborhood that I use and like are all manual-focus:
* Nikkor 85/2 that I simply modified to PK mount. Great lens. Always with me.
* Vivitar-Komine 90/2.9 macro (M42). Seen in various brands. Even greater lens.
* Meyer Trioplan 100/2.8 (M42). Demand may have driven prices out of range.
* Super-Takumar 105/2.8 (M42). Some hate it, I don't know why. I love it.
Bargain glass in that range is scarce. 90mm AF macros are well-liked, as is the aforementioned Samyang 85/1.4. Good luck!
