Recommended photographic equipment for children.

If you want to study photography seriously, buy a SLR-the quality and function of SLR are incomparable to that of guest films. However, the control of SLR is more complicated. If you can't control it correctly, the film may not be good, or even very bad-it's not as good as a mobile phone.

According to your situation, you can't upgrade to 35 Quan Huafu, and an APS-C entry SLR is enough for you. So I suggest you give priority to Pentax K-r, the entry-level digital SLR with the highest cost performance, with complete functions, good workmanship and low price. Followed by Pentax K-30, the most versatile entry-level SLR (biD7000 and 7D are very strong), with the best workmanship and excellent performance.

If you only consider Canon, I suggest you use D550. Although it is not as complete as K-r, it is still sufficient and cost-effective (Canon is not complete, even 5DII doesn't have the repeated exposure function of K-r, and the repeated exposure function only exists on 5DII, but it still doesn't have the automatic continuous shooting function of K-30).

Nikon, you can consider D5 100, which is cost-effective. But don't buy D3200, because D3200 has nothing but pixel height, and its virtual high pixels can't effectively improve the image quality. When you try to shoot with a small aperture, the picture quality will be seriously degraded.
