My current dilemma is I want to get an RF wide lens to accompany my more used 70-200mm and 100-400mm. I had the EFS 10-18mm which was the only choice for crop that made sense but I've recently gone foolframe.
I'm down to three optons and I've read all the reviews and charts I need, but I still can't make my mind up. Any anons please weigh in. I do landscape, and sometimes do musuems and exhibitions that a UWA/Wide come in real handy for.

>RF 28mm f/2.8 STM
Cheap new, tiny, light, relatively wide aperture. No IS, no clicked control ring. No zoom, which I'm a little worried about.
Optically excellent except for the relatively strong barrel distortion.
Tempting, especially considering it's native.

>EF 16-35 F/4 IS USM
20% more expensive, used. Much heavier and longer + adapter. Decent IS, decent aperture brightness, seperate clicked control ring (via adapter). Nice zoom range from UWA to 35mm which is wholly useful.
Optically great but still falls behind the RF 28mm.
Also tempting, mostly because I much prefer zooms for their versatility.

>RF 15-30 f/4.5-6.3 IS STM
About the same price as the EF 16-35mm, new. Half the weight of the EF 16-35mm, 3x the weight of the RF 28mm. Size in between both. Great IS, but real shitty aperture brightness. No clicked ring. Nice zoom range but shifted more towards wide.
Optically meh, but a zoom that's still small and native. I feel like this is the weakest choice that simply fits the middleground.

2600Eu for a 700mm f/5.6 isn't bad. I don't know how often you'll need it but value-wise it's a good deal. Probably great for air shows and birding but fuck that's going to be a lot to haul around especially on top of a 1kg DSLR
