with the addition of Olympus' 15mm/8 body cap lens, I'm wondering what the design or physics limitations of releasing variants in other fixed focus/aperture focal lengths. Back in my film days, one of the best pocket cameras you could buy was an Olympus Stylus Epic with a fixed 35mmf/2.8 lens. It took very sharp pictures and I always had a roll of Provia 100F loaded. The camera was full frame (obviously) and it was tiny. With the smaller m43 sensor, this makes me wonder how small they could make a 17mm/2.8 fixed focus/aperture lens. It would be great for just grabbing one lens and going.
