Built with an apochromatic (APO) optical design utilizing low-dispersion glass elements to minimize chromatic aberrations and maintain sharpness. The DG coating optimization reduces flare and ghosting when used on both full-frame FX and APS-C DX digital SLRs, as well as 35mm film bodies. Features full electronic communication contacts and mechanical drive pass-through to retain autofocus and exposure metering functions on supported telephoto combinations. Housed in Sigma's durable EX matte finish barrel with a side lens release catch. Complete with front cap, rear mount cap, and original Sigma EX padded nylon zippered storage case.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCondition\u003c\/h2\u003e\n\u003cp\u003eOverall Condition: Excellent\u003c\/p\u003e\n\u003cp\u003eCosmetically in exceptionally clean condition with minimal signs of handling on the EX matte outer coating.
