Feel free to tell me I'm dizzy, but:
I find correctly perspective corrected images to make the buildings look top-heavy. You've got the lines straight and parallel, but what I'd want would be a perceptually realistic (yes, that doesn't mean anything: sue me) rendering. And I don't know how to do that.
I let my Canon 24 TSE II go because with the adaptor it was just too much of a clunker on a mirrorless. Sigh. So I haven't put in anywhere near the amount of effort this deserves.
