Cosina/Voigtlander make a 10mm rectilinear, and have had various 12mms for 20 years or so. Nikon had a 13mm f/5.6 in the 1970s:

Not all that long a walk to 9mm, especially since specced focal lengths are often "rounded" to the nearest whole number.

Google search leads to original article with embedded yt video. Pre-production unit on review.

According to pictures in this article from this lens, "rectliner" lens is something which gives straight lines, but they are all crooked.

I'm  not so sure, Ko.Fe.; I've just had a look and as far as I can see the ones where there is curvature of straight elements were mainly seen in those images shot on the Fuji GFX 50R and, to a lesser extent, on the Canon. The 'straight-bits' in the shots taken on the Leicas looked pretty straight to me but I didn't download anything to check it in Photoshop.

9mm is not a focal-length I can ever see me using but nice to see someone thinks its manufacture is worthwhile!

I have seen it around the rumor site for a while, looks real enough! I do wonder how sharp it is in real life use

... and I do wonder how useful it is in real life... 🙄

a funny exercise, anyway... and they'll surely sell some, if made... Personally... when I switch from my Elmarit 21 asph to my CV 15... I always tend to think "wow ! exaggerate ! but sometime can be useful.." 😁

I don't know about the Laowa 9 mm (or how sharp it might be) but I've been using the Voigtlander 10/5.6 for a while, Luigi, and it's a really fun lens.  You can get really close to the subject and have lots of environment around it to play with because of the natural depth of field offered by the ultra-wide field of view.  It gives you a completely different perspective, which is quite useful for some subjects.  It's really important to keep it level because 'keystoning' takes over very quickly if you don't.  The lens was about 6 inches away from the bread in this picture.

As lens technology progresses so too does our ability to utilise it. This has been the case ever since photography was invented. The last areas where significant optical refinements are likely are in wide-angle design (focal length and speed) and fast zooms. Everything else is pretty well fit for purpose and only nuances of improvement are likely.

@farnz really cool!  Does 10mm make sense except in rare situations?  Does 12mm make more sense?  CV is also f5.6.  I have the WATE and a CV 21/1.4, and wonder what makes sense closer...

Thanks.  I think it's another way of 'seeing' and encourages you to consider what scenes would lend themselves to ultra-wide where there are strong foreground and background elements that blend in a single shot.  So a different perspective from, say, 50 mm.

I've never used the 12 mm but I've had and used the CV 15/4.5 Super-wide Heliar for many years and the 10 mm just allows you to get a bit closer.  The 15/4.5's close focus distance is 300 mm but with the depth of field available from such a wide angle lens, in reality objects closer than 300 mm will be acceptably in focus with a narrow aperture and the same for the 10 mm (500 MFD) so I imagine it would be similar for the Laowa 9 mm too.

You're maybe right... but if only I think to the hundreds of posts in this forum about those nuances in the trivial "28 to 90" area... 😉   😁
