>>2903647>considering buildings don't lean backwards, it's easily 20mm or widerHAHAHAHA. Oh god. Glad to see you're still around.
You did manage to stumble on getting close to the correct answer (17mm, as anyone with either enough visual literacy or enough ability with Google could image search and find out, I suspect you're the latter because...) while citing something that makes you even more retarded as the reason for it.
You truly are the gift that keeps on giving.
See pic related? That building is straight. You're just used to seeing uncorrected perspectives. The lens used was the Canon T/S E 17mm. That has literally nothing at all to do with focal length. You can have movements on a 300mm lens (it'd be ridiculously large to still project a large enough image circle, but that's beside the point) and make a building look like that.
>>2903676heh, I approve.
