I am having fun with my Rodenstock XR Heligon 100mm f/1.5 (or to be precise in this case a Qioptiq branded one, as it was made after 2009). Compared to the Heligon 100mm f/1.6 I also own the flange distance is much shorter, on my Sony A7 the lens can't made to go close enough to the sensor to reach infinity, so I am limited to closer focussing distances. Luckily I like macrophotography so that isn't much of a drawback to me.
