Condition

Used – Working with user marks
This lens is fully operational with smooth focus and aperture movement. The glass has light cleaning marks and minor internal dust — typical for a lens of this age — but no haze or fungus. The front element may show some coating wear, which is common with Summitars. Cosmetically, the barrel shows signs of age and use, but the collapsible mechanism works as it should.
