I just spent an enjoyable month in Japan visiting one son who has been (and still) working/living in Tokyo for the past 3 or 4 years. My other son (grad student at UBC in Vancouver) joined us. I took my Rolleicord III with me and enjoyed using it. At 830 grams (30 ounces), along with a otherwise too short carbon fiber tripod (great for waist-lever finder) at about a kilo made for a nice light-weight quality set-up. Often carried on the tripod if actively looking for images, but put the camera in the over-the-shoulder bag (with light meter, film, etc) if just trying to keep up with the two boys (who, in general, were very patient with the old man).
Lost my beat-up, taped-up, Rollei lens shade somewhere along the way, but towards the end of the trip. Exposed 16 rolls -- have the first 4 loaded on reels and in tanks, ready to develop. I took the camera for a month in Scotland last Spring -- judging by the negs, I tended to over-expose a stop (have not tested the shutter speeds). So I kept the yellow filter on the camera most of the time this trip and did not adjust exposure for it...although I took the filter off a few times in low light or if I thought the filter would alter the light in a manner I did not want.
