Im getting so annoyed trying to pick out a lens for my Canon Rebel T7. Basically my sister is getting married in three months and she begged me to take some portraits of her and her fiance before the actual day since I have the camera, but honestly the kit lens that came with the body is just not cutting it anymore. It looks super flat and I cant get that nice blurry background effect I see everywhere.

Ive spent like ten hours reading forums and watching youtube videos. Everyone keeps screaming about the Canon EF 50mm f/1.8 STM because its cheap and sharp, which sounds perfect for my budget since Im trying to stay under 200 bucks, but then I see people saying that on a crop sensor body like the T7, it ends up being way too zoomed in for indoor photos. Like, I dont want to have to stand in the neighbors yard just to get a headshot, you know? Then I looked into the 85mm lenses but they seem even more cramped indoors and way more expensive. I also saw some weird stuff about Sigma lenses but I have no idea if they actually work well with the T7 autofocus or if I need some special adapter which just sounds like a huge headache.

Im in Chicago so its pretty grey and gloomy right now, and most of these shots are gonna be inside our small apartment or maybe a dim hallway, so I need something that actually works in low light without me having to crank the ISO until the photo looks like a grain sandwich. My head is spinning from all the technical specs and conflicting advice about focal lengths and crop factors. Why is this so complicated? Does anyone actually use the nifty fifty for indoor portraits on a T7 without wanting to throw the camera out the window, or am I better off saving up for something else entirely? Seriously just tell me what to buy before I lose my mind...
