You can of course choose shorter exposure times because of the open aperture, which may be an advantage in the shade, in the evening or in dark corners, especially if you are taking photos without a tripod. Where desired, the bokeh is also a dream. The depth of field can really play off best in strong foreground-background contrasts, such as in portraits. It's possible that the crop factor, e.g. with small format cameras like my 550 D, ensures that you get a slight telephoto effect, i.e. you might not get a complete sky on it at all.

In general, for me this lens is mainly a portrait - personal photo equipment - for indoor sports I would recommend a fast telephoto lens

1. Much quieter and faster when focusing because USM autofocus. 2. Slightly faster 3. Bayonet made of metal and not plastic, which means less wear and tear and a more accurate back focus 4. More valuable feeling 5. Both have the disadvantage that the lens changes its length when focusing. 6. With both, there should be no pressure on the lens barrel, so always leave the lens hood in the working position. 7. Both offer good value for money. 8. Haven't regretted the change.

Yes, absolutely recommended. The L with 1.2 is of course much sharper and better corrected in the corners, but the 1.4 brings very good results on my 5D Mark III

Hello, when focusing, the front lens moves back and forth, but it doesn't rotate. The use of a polarizing filter is therefore unproblematic.
