Before being relisted, all of these products undergo thorough inspection and functional testing by professional technicians to ensure that image quality, focusing, and aperture operation all meet our usability standards. They may differ from brand‑new items only in terms of cosmetic appearance or lens glass, where minor flaws may be present. After evaluation and grading, we offer different levels of discounts based on the actual condition of each product, allowing you to purchase a fully functional SLR Magic lens at a more affordable price, with a clear understanding of its grade and condition.
