1. As for the picture quality, it is not as good as a full-frame machine, such as 5D II, but compared with other machines in APS-C format, we can't see the difference, so the difference in picture quality is relative.

2. In terms of control, it is much more comfortable than 5D II. It can be said that except for the image quality, the others are not worse than 5D II.

3. Because it is APS-C format, the viewing angle is smaller, and it may not be wide enough for indoor use, especially for the lens of 24-70. The wide-angle end is equivalent to 38mm, and there is no wide angle at all.
