I'm curious how it will stack up against the Laowa 15mm F2. Both are manual focus 15mm with filter threads, but one is bigger and heavier for 2 extra stops, now we need to see about IQ.

Certainly interesting. I am a little surprised at the weight though, when you compare to lenses such as the Samyang 18mm f/2.8. Still, this is 15mm (albeit f/4) rather than 18mm, and we will have to see about IQ.

Interesting how the market is shrinking, but new players join the game, e.g. NiSi, Yongnuo, and Laowa.

Yes, I know NiSi aren't new to making lens filters.

Too slow for Astro, one of the use cases for this focal length. Could be useful for landscape, but frequently that is covered with a wide zoom. So, not seeing a big demand for this lens. I’m sure some forum members will enlighten me.

Maybe architecture but I agree that it is too slow for astro and hard to beat the Samyang 14mm/2.8 in the cheaper end of the market. 15mm is covered by the Tamron 15-30mm or Irix so hard to see where it would compete.

WOW! That size is amazing! With an native RF mount, its a super compact package that we get here on an R5/6 camera! Thats nice for travel (aaah, damn corona).
I think F4 on ultra wide lenses is totaly fine, and the sice is great. For landscape and architecture but especialy travel this looks promising. Though I wonder how well the image quality can be.
