Hello all. Over the weekend I received a K2 Rolleiflex Model 621 that I had purchased from a seller on eBay. It's fairly rough, cosmetically, but seems pretty good mechanically. I'm having a bit of an issue with the focusing mechanism, though. When I try to focus to infinity, The knob stops turning at about the 5m mark, and it doesn't really feel like a very positive stop. I'm trying to determine if this is a problem with the knob itself just being out of position, or if its a more serious problem with the focusing mechanism. The focusing knob does turn smoothly and quietly. No rough spots in the action that I can feel. My first question is a simple one. I'm assuming that the distances on the knob are in meters. Is that right? Secondly, if anyone has a K2 Rolleiflex, can you tell me if, when you set the lens to infinity, does the lens board (not sure if that's what you call it) meet flush with the front of the camera? Mine leaves about a 1-2 mm gap. I've attempted to verify the focus myself, using Scotch tape stretched across the film gate and a 50mm lens as a magnifier. With the focus set as close as I could get it to infinity (5m on the knob), distant trees did seem to be reasonably in focus with the lens set wide open (as well as I could tell with this set up anyway.) I also focused on an object measured to be 6 ft (1.8m) away. Here's the position of the knob at that setting. What I find interesting is that the 1.8 mark on the knob is pretty close to the position of the infinity mark when focused to "infinity." (see below) Lastly, with the lens fully extended to the close focus distance (and there's definitely a hard stop at this setting) the knob shows just less than 2.2 meters. Does this match up with anyone else's sample? I realize that the knob is not marked for the correct distance at close focus, I'm just trying to verify the position of the knob. Thanks in advance. P.S. I don't have the funds at the moment for a CLA but I might like to have this done at some point in the near future. Any recommendations for some one to do so, preferably in the US?
