It seems since my post back in 2021 about the 40mm lens https://brown-family.org.uk/50mm-to-long-35mm-to-wide-meet-the-40mm/
Many manufacturers are now releasing one.

If you check out social media and YouTube everyone is shouting about how great the old Minolta 40mm is; the Sony, the Canon, the Nikon.
I think partially what’s driving this is the fact that many of these are character lens. Modern Sigma Art, Sony G Master lens, Canon L glass, Nikon S glass etc are striving to be as optically correct as possible. Many people feel that these lens lack character, are boring, and sterile.

If your after a character lens then Voiglander are a great place to look. Many of there APO lens are very good but some like the 40mm f/1.2 are very interesting. Wide open these have older characteristics which many find pleasing. Stop down beyond f/2.8 and there sharp more normal lens, open up and they offer character and a more interesting look. This will not be for everyone but many appreciate this.
Nikon themselves have jumped on this bandwagon with there none S f/1.4 lens, and the 40mm f/2 being particular notable and has quite a fan base.
