If you want funky bokeh in an easily usable lens at a great price then this is the one to get. It has beautiful swirly bokeh, a useful focal length and high quality construction. This lens also comes with a follow focus gear mod, a ring with gear teeth that interfaces with follow focus systems for video.
This one is in good condition with moderate wear. There are some fine circular marks on the front element that may soften your image slightly, but the effect will look nice in the right conditions with the swirly bokeh. Otherwise the glass is clean and scratch free and everything works perfectly. There is a small amount of oil on the aperture blades, but it does not affect their function.
