I recently received a copy of the new Rodenstock 23mmHR lens for my Alpa cameras. I have been using the Schneider 24mmXL Digitar with great success but the added coverage of the 23HR was very tempting so I got one. Here are some quick and somewhat rough comparisons of image circle coverage and shift capabilities and I choose a subject that would help discern distortion characteristics. For the image circle comparisons I used the Alpa Max camera and keeping the lens still made four quadrant exposures and put them together in CS4. I didn't spend much time on LCC corrections so you will see some color shifts.
You will also see 0mm shifts of both lenses and I then posted 5mm upward shifts of both the 23 and 24, and then 10 and 15mm shifts of the 23. The 24 is out of coverage at 5mm so I didn't do those and the camera will not allow such large shifts of the 24.
Small, lightweight, very little distortion, $5k, vs $8k for the 23HR
Much better coverage, no center filter required, lighter wallet to carry around
