Excuse me, why does a 14-70 lens of Canon 5d2 feel a little distorted? Excuse me, which lens is the best for 5d2? thank you

If you take a portrait with a wide-angle end, it will definitely deform, and the focal length can be more than 35mm. It will not exceed 50mm, and the serious deformation may be caused by the unsatisfactory wide-angle portrait shooting.

The most commonly used zoom lenses for portrait shooting are 24-70 and 70-200. The most fixed focuses are 501.41.2 and 85 1.8/ 1.2. These are classic portraits. Whether to buy zoom or fixed focus depends on your needs.

Answer: 17-40 itself is a wide-angle zoom focusing wide-angle. Of course, it was obviously modified for taking portraits. This 35mm head can be used to take small wide-angle portraits, but if it is wider, it is not recommended. The best portrait lens has been said above, so I won't repeat it.
