I am still using my 60D today, if you shoot in Raw the picture quality is good even for todays standarts. You will get the body pretty cheap and as a beginner you will be the bottleneck for a long time. Its the photographer not the camera. Good cheap lenses are: Canon 50mm 1.8 STM Canon 70-200 f4 USM Canon 24mm f2.8 Sigma 17-50 f2.8
The Canon 600D provides exterior measurements of 133mm x 100mm x 80mm (5.2" x 3.9" x 3.1") with a weight of 570 grams (1.26 lbs) and the Canon 650D has specifications of 133mm x 100mm x 79mm (5.2" x 3.9" x 3.1") accompanied by a weight of 575 grams (1.27 lbs). See the Canon 600D and Canon 650D in the latest Camera with Lens Size Comparison Tool. Canon EOS 700D review: A great camera, but surpassed by the 750D The old 600D and its predecessors also suffered from various niggling problems. 700D vs 600D live view autofocus test. Best I still use my T3i (600D) bought in 2012. It still works great and can deliver really good pics, specially if paired with a good enough lens. There are a lot of inexpensive options, the first everyone recomend is the 50 1.8 and I agree, your girlfriend will take excellent portraits and close ups in general, but it can be a little too tight for group of people (particularly indoors) or Has phase-detection autofocus for videos. Canon EOS 600D. Nikon D5200. A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear. has continuous autofocus when recording movies. Canon EOS 600D.
