nikon 50 to 300mm lens

The 55-300 has the focussing ring at the front, but it's a very cheapo plastic lens that I can easily imagine breaking in the bush. The 50-300 ED looks rugged, and has the perfect focal range for a two-body setup (I work in very dusty environments). The 50-300mm is built very sturdily, although the AI-s version is a bit lighter than the AI. harga obat kaditic 50 mg
