Hi All, I have a Bronica S2A (matches all web-derived-wisdom relating to the differences between the S2 & S2A) with what looks like an earlier helicoid. All the photos I've seen of the S2A show it with a helicoid marked in metres for the 75 & 100mm lenses. The one for my S2A is marked in feet for 75, 80 & 100mm lenses. While I'm pretty sure it works fine, I'm interested to know if the focus distance in feet will be accurate? Also, are the helicoids part of the lens, part of the body or a separate part altogether (ie. if buying a used lens, would you expect the helicoid to be included)? John.
