Im so stoked because I finally upgraded to the Canon 90D after using my old Rebel for years and now I really need a dedicated portrait lens because I'm shooting my sisters wedding portraits in a park here in Oregon this October so I want that blurry background look everyone loves. Ive been looking online and everyone says the 50mm f1.8 is the go to starter but then I also saw people raving about the 85mm f1.8 for that extra compression and creamy bokeh.

My logic was that since the 90D is a crop sensor the 50mm is basically an 80mm anyway which is classic for portraits right? But then I started worrying that if I go with the 85mm it might be way too tight since it turns into like 136mm or something crazy on my camera and I dont want to be standing a mile away from my sister just to get her in the frame especially if the park is crowded. I have about 500 bucks to spend so maybe there is a Sigma or Tamron option I missed? I saw some people mentioning the 30mm Sigma Art but that seems too wide for what I want maybe? I just want her to pop from the background without it looking distorted or me being too far away to give her directions lol... what do you guys think works best for the 90D sensor specifically?
