Sigma 105mm f/2.8 overview

  • 1Description

The Sigma 105mm f/2.8 EX DG OS Macro Lens for Sigma Cameras delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to life-size (1:1) macro, as close as 12.2" (31 cm) without accessories. A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent correction for all types of aberration and distortion. Its non-rotating front lens group makes it easier to work with polarizing filters. A focus limiter helps divide the broad focus range into more manageable chunks.

The "focus-free" mechanical design allows the lens to autofocus without any interference from the manual focus ring, making it easy to hold the lens without affecting the speed or normal operation of the autofocus function. Rugged mechanical construction also makes it durable enough for even the heaviest use required by professional photographers. This is an ideal lens for a wide variety of applications from nature photography to portraiture.

The improved DG lens design for this lens corrects for various aberrations. This macro lens is specially coated to get the best color balance while cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras. Sigma's own proprietary OS (Optical Stabilizer) system enables handheld close-up photography.

Close focus capability of 12.3" (31 cm)
Optical Stabilization (OS) enables handheld close-up photography
Super Multi Layer (SML) coating reduces ghosting caused by reflections from the surface of digital image sensors
Dual Focus (DF) makes the lens easier to hand hold during AF

    Sigma 105mm f/2.8 reviews

    105mm f/2.8 EX DG OS Macro Lens for Sigma Cameras is rated 5.0 out of 5 by 4.
    Rated 5 out of 5 by from Terrific Lens! I used this lens yesterday for the first time and took 180 macro shots of butterflies. The lens performed terrifically. Focusing was fast, quiet, and accurate, and images are very sharp.

    Rated 5 out of 5 by from Amazing lens I've used Sigma products before as well as just about every other cameras and lenses from Minox to 8x10 over the years (OK I'm a dinosaur) and they have definitely upped their quality over the years. I tested this on my new 51 MP Bayer equivalent, Foveon sensor Sigma SD Quattro H, against my Hasselblad 110mm f 2 3rd generation lens with a Kipon lens adapter on a heavy tripod using the 10 second delay to reduce any movement from me and at comparable f stops, I almost cried when the Sigma had more resolution, contrast and color saturation. However, I needed to pixel peep to see the resolution differences. I still will use my Hasselblad lenses since they've been sitting unused for awhile and I can adjust contrast and color saturation in Photoshop and I can only print at 16x24 where the resolution difference at 300 dpi is not visible but I will definitely use this lens for studio and tripod macro work outdoors!

    Rated 5 out of 5 by from So Far So Good I bought this to use on a new Sigma SD Quattro H. The effective focal length is 140mm, so I use it the way I would a 135/2.8. I'm not equipped to do serious bench tests, but I did try it at various apertures and found it very good wide open, then even better up to f/5.6 or f/8, and still fine through f/16. I try to use it f/8, generally, sometimes with focus stacking in a studio setting. There are three switches on the lens: 1) image stabilization on, full, vertical only; 2) AF/manual; 3) focus limiter (full, 0.45m to infinity, 0.312 to 0.45m). Also a distance scale. Aperture is set by the camera body. Because the Sigma SD's sensor is smaller than full frame, yet very high-res, I get the benefit of using the best part of the lens's coverage -- in other words, the corners of the frame are well inside the fringes of the circle, where definition inevitably falls off. The bench-test reviews I read before buying say this is an exceptionally sharp lens, and my results bear that out. I'm satisfied. One reason I went for it is that's it's a true macro, capable of 1:1 reproduction, yet suitable for general use. It has a focus range limit switch to speed up AF, which is still slow on the SD. However, I use the camera mainly for studio/tripod work, mostly in manual-focus mode. I can't say how fast the focus would be on a Canon or Nikon body. It's silent, as you'd expect, but if you turn on OS (image stabilization) you get a little noise. Again, not a big problem for me, since I turn that off for tripod use. However, I consider stabilization essential on a lens of this focal length; I will use it handheld from time to time. It's a biggish lens -- made for full frame use, after all -- and extremely solid. Externally, at least, it's very well made. A bit heavy, but hey. It came with two lens hoods, one for full frame and one for APS-C use, a nice touch. (On an APS-C body the effective focal length is 157mm.) The box also contains a nice case for the lens.

    Rated 5 out of 5 by from Terrific Lens & Retailer I am a Hobby photographer and have wanted a Macro lens for a long time. B&H's price and Sigma's great lens allowed me to obtain one. It is proving to be one of my best lens. Very sharp and clear photos. The only minus to it is that it is under rated. Professional photographers may feel the need to buy the more expensive brands but this one is perfect for me.
