I'm freaking out because I promised my sister I'd do her graduation photos next month but all I have is the kit lens that came with my T7 and the shots look so flat. Everyone says get the 50mm f1.8 because it's cheap but then I read it might be too zoomed in on a crop sensor? I dont want to be standing a mile away just to get her in the frame but I need that blurry background look.

• budget: under $150 (used is okay)
• use case: outdoor senior portraits
• goal: professional looking bokeh

Is the 50mm actually okay or should I look at something else? I really dont want to mess this up...
