Sigma 105mm F2.8 EX DG Reviews
FourThirdUser reviews the Sigma 105mm F2.8 EX DG and writes;
“There is much to like about the Sigma 105mm Macro EX DG for Four Thirds. It feels solidly built and is positive in handling and results. It’s also a very versatile lens, useful for portraits and medium telephoto work, especially in low light, as well as macro work….Sigma’s manual/auto focus mode switching takes some getting used to, but the mechanical manual focus actually works very well.”
M.Olson reviews the Sigma 105mm F2.8 EX DG Macro and writes;
“To sum it up, I did not expect great things from this lens given that some of the Sigma lenses in the Four-Thirds mount have been a disappointment, but I was pleasantly surprised by this lens. It is sharp at maximum aperture from edge to edge, it is moderately priced, it is an excellent macro lens, and it is a fine medium telephoto lens on top of it all. I can highly recommend this lens as a handy addition to any Four-Thirds DSLR camera kit, provided weather & dust proofing is not needed.”
