Canon Macro Lens, Ef 100 Mm 1.2.8 Excellent condition Retail 600 Last time used was in 2017 - was working fine then. I sold my cannon 5D so I cannot test it. It maybe has dust in it. But as far as I know it is clean just has not been used in a long time been stored since I quit films But please no low offers I posted the lens with the cap off etc. thank you
