The Sigma DC 18-200mm f/3.5-6.3 II HSM OS AF DC Lens for Nikon F offers a versatile zoom range suitable for a wide variety of photography needs. Made by Sigma in Japan, this lens features both wide-angle and telephoto capabilities, making it ideal for capturing different perspectives. With a maximum aperture of f/3.5-6.3, this lens allows for good low-light performance and a smooth bokeh. Additionally, the lens is designed for auto focus and zoom functionality, providing convenience and ease of use for photographers.

Auto focus is not working, likely a broken flex cable as this is a common issue with these lenses, aperture was tested on Nikon body and works just fine.  I used the lens in manual mode using a Nikon to Sony E adapter (with aperture control) to take some test shots.  Lens is quite nice, very sharp and easy to use in manual mode.  Should be a relatively easy fix for someone with the technical knowledge.
