Whoops, we did blow right by that focusing direction one didn't we lol. I just automatically go to super takumars when I think of awesome character, slower, and readily available primes for cheap, they're the kings.
To be fair, it's in the list of preferred characteristics, so maybe theres some wiggle room for the right set.
If it's a requirement, I'll double down on my Olympus OM recommendation and also throw out SSC Canon FD lenses, there's a 17mm 4, 28mm 3.5, 35mm 3.5, and a 50mm 3.5 macro and 100mm f/4 macro.
Bonus/wide lens could be the 24-35mm 3.5 L which might be just over budget.
