>>4021002Passive TTL metering means you don't have to compensare for filters and because the ISO meter goes to 1600, you can manually compensate to 6400 using the meter. Others crap out long before that.
But once again, Canikon and Minolta also have similar offerings across model ranges and feature sets, Olympus was already doing electric shitters on the OM1 and Asahi's response was to miniaturize a k1000 and stick a passive meter in it. Other than a shutter shitting itself above 1/60 on a rough looking camera that was probably never serviced since it was built, they're pretty robust.
