Kind of a rookie with pano and large format lenses. Just bought a older Gaoersi body, installed my Fuji 90/8, and then discovered it won't focus at infinity. The focus mechanism is all the way in and it is beyond me how anything could be adjusted to get it closer. Hence, am I correct in that it has something to do with flange distance? The camera measures up at 102mm and I'm afraid my Fuji needs shorter than that. Any advice, including which lenses might work, would be greatly appreciated. (Seller wasn't sure what lens used to be on the camera, thought maybe a Super Angulon) Roger in Michigan
