Purchased around 2017. This is a telephoto lens with a focal length of 150-600mm and an aperture of 5.6-6.3, for Nikon F mount. I was using it until last year. The frequency of use was at most about 7 times a year. For the last 3 years, I've used it once or twice a year. It has been updated with TAPinConsole. . It has been stored in a dehumidified storage cabinet, and I've used it with a protective filter (Marumi) attached since purchase. There are small scratches on the tripod collar and zoom ring due to years of use. Included accessories: protective filter, dedicated case, lens hood, front and rear caps. The box is stored separately, so please comment at the time of purchase if you would like it. #TAMRON #Tamron #TelephotoLens
