That chart is a bit deceiving, that Ti is a small rangefinder. Here is a real time comparison. These are only quick snap shots. Sorry I just didn't have time to set-up properly and I wanted to post a few pics that I promised.
If you ever held an EM then you pretty much get the idea of the FG size.
I tried to go small, bigger, biggest. The ME clearly is the smallest but not as versatile and the Nikon isn't much bigger at all. Next to my F4 all these cameras are midgets.
This is the Nikon N70 in comparison.
