I don't use it often, and I usually store it in a dehumidified cabinet. It has some minor scratches, but the exterior is quite clean. I think there's little dust inside the lens. I've been using it with a mount adapter LA-EA5 and an α7R5, and it works without any problems. It's an AF macro lens, but when shooting near 1:1 magnification, I preferred manual focus over AF. However, since it has an ultrasonic motor, the AF operation is quiet. The image quality of the Tamron lens is excellent. How about it? I'll also include the photo filter. To prevent swapping and because it's a used item, I'm offering it as-is, no claims, no returns. Please understand this before purchasing.
