I did not know that the OP was asking for faster than f/2. But for true mechanical, ergonomical and optical quality the Color Skopar is the best.
61 LD is not f3.5. OP was not asking about ergonomics, but for faster than f2 lens with modern character.
It is hard not to get OK pictures as Skopar does with maximum f2.5.
I highly recommend always read and understand OP before posting. But nobody is perfect.
