What kind of lens is suitable for children's photography Canon 50D?

In fact, I would like to recommend that you buy a fixed focus if you only shoot children, preferably 85, and indoor 35 is not bad.

If you like zooming, the effect will definitely be much worse, but these three models still recommend 24- 105. As for the wide-angle problem you mentioned, not to mention how difficult it is to control a good wide-angle photo, can you meet this technical requirement? But when it comes to shooting children, do you think wide angle is important? This 24- 105 is not as good as 24-70, but it is still good. Usually shooting is really enough. You see, many photographers, even masters, shoot all over the world with a small fixed-focus lens of about 35, so don't compete with nature. The most important thing is to buy one and then hone your skills.
