The 40-150R is very good for being like 100$. Got one to mess around with tilt shift photos of suburbs that my family enjoys. The PanaLeica 15mm f1.7 is pretty good street/EDC lens. The OM 20mm f1.4 is pretty good as well. It has chromatic abberation and isn't overly corrected so it has great contrast and really pops. The OM 12-100 F4 is a very cool feat of engineering and has pretty good optics for how crazy it's range is. I personally don't really like spending that much on a M43 lens though. I buy M43 to get cheap gear I can trash that's like 95% of the quality of my nikon full frame.
