According to my research, both are technically identical. There is an EU model and a CH model, as the manufacturer usually gives a longer warranty period for the CH model in Switzerland if you register the product with the manufacturer. In addition, a CH product can participate in cash-back campaigns from the manufacturer in Switzerland, whereas an EU model cannot. Technically, however, they are identical as mentioned above. The release date on our website indicates the date of the sales launch in Switzerland and not that of the manufacturer itself. Unfortunately, I am not aware of a 2024 model; Sony launched the lenses on the market in 2015.
