How to choose a safe and reliable camera lens shop?

Choosing a safe and reliable camera lens shop requires comprehensive consideration of factors such as product channels, user evaluations, and after-sales service. The following are key points:
Clarify requirements and budget
Before purchasing, it is necessary to clarify the shooting scene (such as portraits, scenery, macro) and budget range to avoid blindly pursuing high priced products. For example, wide-angle lenses are suitable for capturing buildings and landscapes, while fixed focus lenses are more suitable for portrait photography.  ‌
Verify product information
Prioritize choosing official flagship stores or brand authorized stores to ensure compatibility between the lens and camera mount. Check lens parameters (such as aperture, focal length, anti shake function) to avoid purchasing products with overlapping functions or low-quality products.  ‌
Refer to user reviews
View professional reviews and real user feedback, with a focus on optical quality (such as sharpness and distortion control), coating process (anti glare ability), and durability (metal materials are more durable).  ‌
Be wary of low price traps
Avoid purchasing "defective products" that are significantly lower than the market price. Some merchants may sell refurbished or repaired lenses at "defective prices". For example, a certain store called "Letao Digital Studio" was once complained about for concealing defects.  ‌
Combining offline and online
Offline second-hand shops can conduct on-site inspections of lens quality, but attention should be paid to the extent of bargaining; Online platforms (such as Xianyu) need to learn to distinguish authenticity, check whether there are any signs of disassembly or repair on the lenses, the service life, and other details.  ‌
