I use Canon 550D, and I want to buy a lens to take pictures of the following products. Ask the master to guide others' works [the environment is 3 lights in the indoor studio]

Look at the picture comparison, the leather of the two shoes is different, one is partially shiny and the other is matt, which looks not sharp enough.

I didn't see your original picture. Theoretically, commodity posing needs enough illumination from multiple angles, tripod MF focusing ensures sharpness and the lens is sharp enough. I recommend you to use the new Budweiser100/2.8L. Canon's original factory ranks in the top three, and the price is not too expensive. You can also take close-ups of details.
