The 70D has almost identical strengths to the Canon 7D, though the frames per second is a bit slower (7 fps instead of 8 fps) and the buffer fills up a bit sooner than does the 7D. Because the 70D is technically considered a lower-end camera than the 7D (despite being overall more powerful and expensive), the 70D is smaller and lighter than the 7D, which most people consider to be an advantage. https://www.youtube.com/watch?v=Jqc5jwR0uuw Here are the reasons to choose the 70D:
- Autofocus while recording video. This is the only Canon camera that can track moving subjects in video. If you want a video camera for general use, the 70D is the right choice for you.
- Compared to the lower-end cameras (excluding the 7D), it offers amazing autofocus and high frames per second.
- Compared to the 7D, it offers an articulating touch screen and Wi-Fi, making it a better camera for general use.

For just a few hundred dollars more, those bodies offer significantly better image quality and background blur. However, they are bigger and heavier, have weaker autofocus systems, and lack the articulating touchscreen. https://www.youtube.com/watch?v=NjR2OztuXtA Before buying a 70D, consider a Nikon D7000, which can be bought used for about $600. The D7000 offers about 15% better overall image quality, which is a substantial gain. However, the D7000 isn’t as good for action shots, because the buffer fills quickly, and it lacks the 70D’s Wi-Fi and video focusing capabilities. https://www.youtube.com/watch?v=lvY4q91a4a4
