I've ranted and raved against how narrow some :43: usable aperture is, usually because it's a zoom with f/5.6 (or higher!!) at the long end and diffraction setting in at f/8 (or earlier!!). The Panasonic 12-35/2.8 seems to be as flexible as the Oly 12/2.0, so the zooms are improving, but the prices sure are going up! Maybe it's *just* a zoom thing? Olympus seems to have resoundly beaten this f/8 diffraction ceiling with their 45/1.8 and 75/1.8. If Olympus does produce the rumored 25/1.8 or 17/1.4 those will be very desirable indeed. (I'm a zoom kind of guy, but I catch myself buying primes when I'm not paying attention, so either of those might accidentally make it into my bag.) Another rant slips through my fingers.
