Thanks for the tip. You remind me I also have that Leica Elpro. I will give it a try and report back after that. With Elpro, this can be a truly macro lens (1:1?)

Just like the CV 40/1.2 Nokton, the Sigma 45 is not optimized for close distance and lacks a focus floating system.
So, at distances shorter than ~1m, IQ deteriorates compared to infinity mid and infinity distances.
One solution is to stop down the lens to f/4 or f/4.5 but there is also a trick many of us have been using with the Voigtlander 40/1.2. It's called achromat close-up lens. Basically it will force the lens to focus at "infinity" when shooting at close distances and therefore increase IQ substantially.
I just tested the Sigma 45 with the Leica Elpro 3 (55mm) achromat and it's a powerful combination. I can use AF and get much higher performance at the shorter range up to 1.2m where the lens will think it's infinity. It also matches the lens filter thread.
