The Canon Rebel line is great – I had a Rebel (t2i) for several years and it took me from beginner through my first year in business. You’ll learn that while the camera is an important tool, it’s your skill and knowledge that will really take your photos to the next levelAs far as which Rebel, I haven’t stayed up to date on what they’re coming out with, but I would suggest anything above a t2i (the larger numbers – t3i, t4i, t5i, etc – are newer models, so depending on how much money you want to spend you might look into more details on those models, but I think the main differences are things like rotating screens, touchscreens, etc which are nice but ultimately aren’t that important to the end product of the photographs). I would not get a rebel without the “i” at the end of the model because they are the lower end and won’t be as good in lowlight, won’t focus as well, etc.
Good quality lenses are really expensive. Most DSLRs offer the options to come with what is called a “kit lens,” like the 18-55mm or 18-135mm lens. These lenses are not great, but if it’s all you can afford it’s better than your phone for sure. Better quality lenses will result in sharper, clearer pictures, and the ability to open up the aperture wider which allows you to take photos in lower light (especially indoors) and to have those blurry background that everyone is after.
I would recommend getting the Kit Lens to start with unless you have a larger budget. If you have more money to spend, then getting the camera body only along with something like the Tamron 28-75mm/2.8 lens would be a great option.
If you plan on learning Manual Mode right away (which you absolutely should!) I would highly suggest also getting a Prime Lens to work with as these are the easiest to learn with and will result in sharper, higher quality images with those wonderful blurry backgrounds! I would start out with a "Nifty Fifty" which runs about $125 new or a Sigma 30mm 1.4 if you can. The Sigma lens is better quality and a wider, more natural point of view in my opinion and it's what I used on my Rebel when I was learning.
Buying used equipment is a great option to save money as well. Adorama is a very reputable camera store that sells used equipment if you prefer to buy from a store, or I have purchased used equipment on forums, ebay, or facebook groups - just be careful buying from individual sellers and make sure that everything is working right before you do anything!
