How many kinds of Sima APO 70-200mm are there?

Sigma Black has been produced for five generations from the beginning to now. The difference between Sigma Black and Sigma Black is that the fourth generation has marco, that is, macro photography, but there is no OS optical image stabilization. The fifth generation has OS image stabilization, and the outer coating is changed, but there is no macro function. If the landlord is rich and can ignore the cost performance, then choose the original factory. ~SIGMA is a good choice if funds are limited. The answer upstairs is copying, right? Please don't spit if you don't understand.

Satisfied, please adopt.
