Tough question. My favorite lens is my FA*300/4.5, which would not be a good choice for an only one lens don't know what I'll be shooting. I would probably go with my K35/3.5 although I'd be tempted with the M50/1.4. With the 35/3.5 I get legendary flare resistance, and it would work well with the built in flash and zone focusing. I have been known to go to the local baseball game with only the 300 and the 35 on my Z-1p.
