Ive been staring at my 90D for two hours and Im honestly so annoyed right now. I have this big trip to Chicago next Friday and I still havent picked a prime lens because every forum says something different. I looked at the EF 50mm f/1.8 because its cheap but then people are saying on a crop sensor like mine it acts like an 80mm which is way too zoomed in for street stuff? Then I saw the 35mm f/2 IS USM but thats pushing my $400 budget and some say its not even worth it over the cheap one. I just want one lens that stays on the camera for the whole weekend. Does the 35mm actually feel natural for walking around or am I gonna be constantly backing up into traffic trying to fit a building in the frame?
