Is the shop camera lenses cost-effective?

Whether the camera lens is cost-effective needs to be discussed on a case by case basis:
Price advantage
There is a price advantage in physical stores such as Map Camera in Shinjuku, Tokyo. For example, the price of the Sigma 35-150 F2-2.8 lens is about 160000 yen (including tax refund), which is about 50% cheaper than in China. The Sony GM series usually has a discount of 20% -30%, with more significant discounts for third-party lenses such as Tenglong and Sigma.  ‌
Channel cost
The cost of physical stores is higher than that of online stores, but the cost is passed on through added value (such as accessories and services). Although the rent for online stores is low, they need to bear additional expenses such as 24-hour customer service and logistics. After balancing the costs of the two, the prices are similar.  ‌
Purchase suggestions
Overseas purchases: Japanese and other overseas physical stores can enjoy tax refunds and discounts, suitable for budget sensitive users;
Domestic purchase: Third party lenses (such as Tenglong 28-75mm f/2.8) during the 618 promotion period have lower prices, and paying attention to parallel import channels can save 10%;
Second hand channels: Online second-hand stores have strict screening but high prices, while offline second-hand stores can negotiate prices and physical items can be seen, but attention should be paid to quality risks.  ‌
