Purchased new on Amazon. ■ Warranty: Yes (with serial code sticker) ■ Storage condition: Stored in a dehumidified cabinet ■ Number of times used: Less than 20 times ■ Condition: Beautiful, as shown in the photos I am selling this lens because I rarely used the 17-28mm wide-angle range! Many of you are probably already familiar with its descriptive power, as there are various sample images available online, but it's quite beautiful. It's especially recommended for those who enjoy taking landscape and astrophotography! Of course, you can also capture beautiful portraits with a sense of depth in the background to preserve your memories. The 17mm wide-angle range, in particular, allows you to capture a wide field of view, and it's very light, making it great for taking on trips!
