SIGMA 17-50mm f2.8 EX HSM This is a standard zoom lens for APS-C cameras. While it doesn't produce extremely sharp images, it offers a refined look. The lens functions without issue, but as it's an older third-party lens, it may be unstable depending on the camera body. In my setup, the image stabilization sometimes malfunctions. There are no scratches or dirt that affect image quality. Being a used item, there are minor wiping marks and dust. #sigmaex #apsc
