I am very pleased with all the Sigma photo lenses. I own a Sigma 105mm f / 2.8 EX DG OS HSM Macro, Sigma 17-50mm F2.8 EX DC OS HSM and Sigma 10-20mm f / 3.5 EX DC HSM and with all we have achieved good results. All work well with my Nikon D5300. What may be the Sigma 105mm f/2.8 EX DG Macro Lens' biggest strength is image sharpness.The macro lens has a single drawback. It has a big weight for my hands that are not so strong! 😀
