I am selling my Nikon 12-24 f/4 Lens with SEACAM zoom gear. The lens and Zoom gear are in excellent condition. This lens works great on Nikon DX or crop sensors and is not recommended for FX full frame cameras. Yes you can shoot it on a on a FX camera but there are better options for this requirement. The lens and zoom gear are available for $600 USD. Retail separately: Lens ($1100) SEACAM zoom gear ($260). Email me if you have any questions.
