Portraits: 50mm fixed focus, cheap f 1.8, as well as f 1.4 and f 1.2L pan/tilt, the image quality is limited, but the price is much more expensive;

Scenery: The original APS-C scenic spot is really not cost-effective. You can look at the wide-angle heads of Sigma and Tully.

Another way is to buy a Canon 15-85 PTZ. Although the aperture is a little small, the basic portrait and scenery can be taken into account, which is a good hanging head.

Besides, 70D has already been bought? Isn't it still on sale?
