I will see what I can do for pictures "from", will have to go through my scans first. For now some specs for
@Räuber and
@Sonnar Brian.
The lens weighs 406grams. With the majority of the weight being made up by the glass and aperture. It's a little bit taller than the a war-time LTM Sonnar 50/1.5 next to it.
Exactly 42.00mm according to my digital calipers. From the mount base (excluding the part that goes into the camera) to the tip.
The rear lens diameter is 29.40mm and there is no empty space between the retaining ring, the RF cam and the focus mount. The front glass clocks in at a girthy 53.64mm.
Due to the girth of the lens the infinity lock arrangement is unusual in that you push towards the center of the lens instead of downwards, the focus throw is the usual 170 degrees from infinity to 3 feet. The lens stops down from f/1.2 to f/16 with click stops for 1.2, 1.4, 1.6, 2.0, 2.8, 4.0, 5.6, 8.0, 11 and 16 positions. There is a marked but clickless stop at approximately f/1.8 or 1.9. The spacing of the stops gets narrower as it progresses but not as extreme as on pre-war Sonnars for example.
Last pictures show it mounted with an L/M ring on a early button-rewind Leica M2. Due to the smartphone wide angle the front of the lens looks larger than it is. One can however put the camera down on a table without the lens touching the table. So there is still 5-7mm clearance to the bottom of the camera, it just does not look like it in these smartphone pictures. There is some and quite a bit more finder obstruction at infinity and 3 feet respectively.
