Undoubtably some dust particles will be present in the lens.
The iris diaphragm works as it should and is nice and snappy. Both the stop down button and the lens release button work as they should. The aperture ring clicks nicely into place.
Focusing is smooth.
The lens comes with new generic front and rear lens caps, a dedicated Olympus rubber lens hood, in excellent condition, and I have added a used but perfectly usable Hoya Skylight (1B) filter should you wish to use it.
Will also come with a new non-branded soft pouch.
I have taken the marks on the elements into consideration when pricing this great little package of the lens and its accessories.
Any questions please ask.
Thank you for looking.
