The images shown in this section have not had any sharpening done in Photoshop. But other than that the Sigma 24-70 delivered on the most important piece, image quality. There was slight signs of purple fringing when I examined some tree leaves in the corner of some images. Even in the corners of the image I lines were still sharp. In Aperture I took out the Loupe (100% magnification) and I was surprised to see how sharp the images came out. The images produced were sharp and the contrast was great. I was really surprised when I got back home and opened Aperture to look at the photos shot with the Sigma 24-70. The addition of the HSM motor is what helps this lens focus fast and accurate while still being silent. But for being about $900 cheaper than the Nikon it performed exceptionally well.

The Sigma would sometimes have to go through the full focus range before catching focus. I found that the Nikon focused just a bit quicker, and was more reliable. I walked around and shot with the Sigma 24-70mm, and would then switch the Nikon 24-70mm in order to compare focusing speeds. It just seems like the switch was an afterthought rather than being designed into the lens.

It would occasionally switch from Autofocus to Manual focus from rubbing against my body while being carried on a BlackRapid strap. The switch does not match the finish of the lens, and protrudes from the barrel of the lens. The only issue I had with the build quality of the lens was the auto/manual focus switch on the side of the lens. That helps to ensure that water doesn’t get into the camera.

The only thing that the mount is missing is the rubber gasket present on Nikon pro lenses. The lens held its own even in the extreme heat.Īs you can see in the image below the lens mount is metal. When I shot some of the sample images, I was walking around in 105 degree weather for an hour and a half with no issues. I was really impressed overall with the build quality. The hood slides on nicely and clicks when it is on correctly. The lens hood is plastic and is smaller than the Nikon version. The focus and zoom rings are made of plastic, but it does feel better than other lenses I’ve used like Canon’s 50mm f1.4. I personally preferred the Sigma’s build quality over that of Nikon’s 18-105mm or 28-300mm lenses. The lens itself feels heavy and well built. I have shot with Canon lenses before so that might be why I’m used to zooming both ways.
This didn’t really bother me while I walked around taking sample shots. The only other thing to mention is that the lens zooms clockwise, opposite to what you are used to on Nikon lenses. We’ll have to see if Sigma’s next iteration of the 24-70mm shares the satin finish. I did notice that on a friend’s Sigma 70-200mm OSM that the lens doesn’t have the same finish. I’m not sure what the lens is coated/covered with but it feels nice. Normally I’m used to feeling either hard plastic or metal when touching lenses. Something else to note is that the Sigma lens has a satin/silky finish to it as well as the lens hood. So not only did I have a lens that had a fast aperture, but it was also small enough that it was comfortable to carry. It’s really bright here so I always like leaving the lens hoods attached. I really don’t like walking around Austin with the big 24-70mm, and its huge lens hood. I liked the fact that it was shorter because it would be easier to take around with me. By smaller I mean it is shorter, but when you look at the lens you notice that it is wider than the Nikon. When I first received the Sigma 24-70 I was surprised at how small the lens was compared to the Nikon version. G – G type Nikon mount lens Overall Impression Here is what all the letters on the lens mean: If you don’t like reading tech specs scroll further down for my review and sample images. The new Sigma 24-70mm f2.8 DG HSM adds a focusing motor and a smaller size.įor those of you who like to read the tech specs, look below. Sigma had previously released a 24-70mm lens, but it lacked a focusing motor. That is where third party companies like Sigma and Tamron come in to make lenses more affordable to photographers. That price tag makes it hard for hobbyist photographers to justify purchasing a lens that costs more than most camera bodies. The only issues that some people find with the lens is that it is heavy, large, and expensive at around $1,700. The Nikon 24-70mm lens is one that has been praised by every photographer who picks it up.
