Do not. I repeat do not be enticed by the cheap prices for photographic equipment. This has been the worst online purchase of all time. I purchased an 85mm Sigma Art lens two months ago for my Nikon D810. The lens does not focus on the spot you select. I have been trying for 50 days to return the defective lens, but Abes of Maine's customer service wont give me an RMA number to return the lens. I spoke the person at Abes, Lisa Berry, and provided what she requested. After that, silence. She does not respond. STAY AWAY!
