I enjoying using the Zeiss Ikon SW for discrete shoots with wide angles. The 3 bulb LED meter display is great when paired with the AE mode (if you remember not to point towards the sky). As I'm using it with mainly the 15mm, I only need to ensure that I don't see the red light on it's own. All other combination will ensure I have a shutter speed higher than 1/15 seconds. So after metering, I just lift up and snap. Very quick.
As for built quality, it's great. There's no rangefinder to knock out of alignment. It's a shame that this camera is so under rated.
Cheers,
