I started out with T3i as a beginner, and I shoot tons of photos without an issue l until someone jacked it up. That is another story from another thread. If you want to save money, and you are a beginner then go for T3i. That is the reason I bought it in the first place, because I didn't know anything about dslr and cost less then highend dslr. It has quick buttons to change WB, AF, picture styles, and drive mode setting. These are easy to use and less hassle to look for in the menu. It also has quick dial mode if you want to switch scene instantly. If you have some experiences then you might want to go for something higher, but it is up to you. As for small frame sensor, you can still take good quality photos. In low light condition, I alway use flash and tripod to shoot good quality photos. Of course 5D Mark iii is best for low light shooting or shooting high quality photos in any situation. I'm not a wedding or sport photographer, so I don't care if anyone has 5D Mark 3. I recently upgraded to 70D, and it is a whole new experience for me. A lot of new settings and 19 AF points. It takes me a while to get use to. As someone said before, it has a LCD panel for a quick glance for the aperture, iso, shutter setting, etc.. You probably don't need it for a beginner. If you have the money and you want one with the LCD panel, then I'm not arguing you. It is a good idea to go to local camera specialty shop, and try these cameras yourself. Ask a lot of questions. You need to get a feel and find one is right for you.
