Has the new 105mm macro lens from Sigma for Nikon many improvements over the previous model and also compared to the 85mm macro lens from Nikon. With the high luminous intensity of 2.8 which persists even with short distances / distance to the subject, since the lens is innenfokussierent, you have little problems with difficult lighting situations. The image stabilizer makes a good impression, the focus with the adjustable distances are going well and also the ability FX can be mentioned as an advantage. The lens is naturally heavier than the 85mm Nikon. By Innenfokusieren you can set up and make use of a ring flash easily. The image stabilizer makes sense when you just have no tripod at hand or if you want to use the lens for normal shooting. The image quality is excellent. One point deduction for the heavy weight even when image stabilization and FX capability me were known in advance, it could be a little lighter (D90 / D7100).
