My thinking is that if you're just starting out, learn on that camera. The thing about camera bodies is they depreciate on the first shot. By next year my 80D will be old news. Now lenses on the other hand stay relevant for a LONG time and they are mostly what provides the image quality. A lower aperture lens will allow you to blur the background more and allow in more light negating lower ISO and maybe a higher shutter speed. Learn the basics on that body and then figure out what features you may want. You're also in a good stance to go canon, nikon, sony, etc. Before you buy anything, think about this. If you were to keep the camera body you have now and buy some high quality glass with the money you saved, when you learned what you liked or needed in a camera or outgrew that one, you'll have the glass to bring to your next body. If you buy a good body and keep the glass you have, you've still got to get the good glass later on down the line. Also, if you decide to resell, glass sells for closer to what you bought it for than a body will, unless you sell the body fast enough after buying it. I used my rebel xti for 10 years and never had issues with the image quality because i had decent glass. Yes, the low light was poor but i learned how to get around that and i think that's whats made me a better photographer than where i started as well as being able to make changes on the fly. Now that i have an 80D i almost feel like i can slack a little, but then i bring myself back to reality. It's like going from a smart car to a truck. You could still fit lumber in the smart car you just had to do it systematically. Now with your truck you can just throw it in and not care. But if you were to still care you'd stack it neatly and fit more in. See what i'm saying? Maybe that was a bad analogy but i know what i was getting at! What i was trying to say is, with my xti, i had to be caution with the ISO and think about the shot, shutter, aperture, lens, etc. but with the 80d I use auto ISO so that's one variable i can forget when i'm shooting most things because i know it'll go to the limit i set. With my XTi i had to set it everytime and be more cautious. I don't know much about the 30D but i still say invest in glass and "struggle" through learning the basics before you upgrade.
