I'm selling my Sigma 18-35mm F1,8 ART with Nikon F mount in like new condition. I bought in in december 2014 and only used it about 10 times since then. It'll ship with the original box and accessories. The glass is in perfect condition without scratches or anything else. As you can see in the pictures I installed two 360° lens gears 0.8mod from https://followfocusgears.com. The lens gears are custom made for the Sigma 18-35mm and fit absolutely perfect. They mount and unmount very easy and don't leave any traces as they just bind to the rubber of the original focus and zoom ring without any adhesive or screws.

Item is located in Germany but I'm willing to ship worldwide at buyers cost.

Asking price is 630€ OBO.
