I’m not coming from having used Canon so I don’t have a war chest of EF mount lenses. I have a t4i that has been my wife’s primary camera for the mast decade. I don’t think that it would be worth adapting either of the EFs lenses (18-135 or 55-250). The 85/1,8 might be a candidate but it doesn’t bear on this discussion.

Right now, then, the 24mm end of the 24-105L will be the widest I have. So I am looking at something wider than 24 to do nature and I want to try Astro landscape stuff. Can someone point to/discuss a good comparison of the 16 STM VS the two uwa zooms?

I haven’t tried either of the L UWA zooms, but, if it’s good for anything, the RF 16mm performs better than the 10-18mm IS STM at the same f-stops, and the venerable, manual Tokina 17mm f/3.5 RMC (known for being the cheapest decent ultra wide available). It’s not better than the EF 17-40mm f/4 L, at least not in overall resolution (the RF prime is sharper in the broad center region, though the zoom sucks less in the corners), but I hate how the 17-40mm renders, so I still prefer the 16mm.

I find that, already by f/5.6, the results from the prime are good enough for what I do. No, it probably won’t work for astro. But on the R6, it’s good for landscapes and some architecture shots.
