Camera Lense Sony FE 70-200mm f2.8 GM OSS 70-200mm f/2.8

I ordered a Sony 70-200mm f/2.8 GM II from Back Market. The advert, photos and description matched the GM2 model, which justified my choice and the price I paid. However, on receipt, I discovered that it was actually a GM1 model. I find this very limiting, especially for a product in this range costing several thousand euros. This kind of mix-up shouldn't happen on a platform renowned for its reliability and control of sellers. It was a disappointing experience, especially as I had confidence in Back Market for purchases of this level.
