Some years ago an acquaintence was looking to test the tlr waters and bought one. He could not figure it out as the manual was either Cantonese. Mandarin or Japanese. He brought it over and asked me to figure it out; not hard as I was used to Rolleiflex and Yashicas. I ran a roll of Tech Pan through it and developed as continious tone transparancies and the results were very good indeed. No jamming, the lenses was a smidge soft, geat for femail portraiture, and the speeds seemed tact on. He used it for some years before deciding to roll the dice for a Rolleiflex. I'm not sure how many Rolleis he has but probably more than most stores carried in inventory. He started with a 3.5 and has collected a huge selection of Bay I filters, acc'ys. He was still carrying the Sea Gull as a back up and as a daily carrier after more than a decade and has put an untold number of rolls through it as he is an avid shooter. So, if you get a good one, it can be a workhorse.
