Sigma 24-60mm f/2.8 EX DG IF Aspherical Lens

Description:

The effective arrangement of Special Low Dispersion (SLD) and aspherical glass elements has created a lens of compact dimensions. With an overall length of 84.7mm (3.3in.) , it is the smallest lens of this focal range. (* As of April 16th 2004. In the category of wide-angle zoom lens with focal length starting at 24mm and with a maximum aperture of F2.8.) This lens offers a large aperture of F 2.8 over its entire range of focal lengths, which is ideal for low light situations both indoors and out. It has a large depth of field that offers the photographer greater freedom of expression.

Sigma 24-60mm f/2.8 EX DG Lens Zoom View

From super-wide-angle of 24mm this lens has a very compact design as well as a large-aperture. By effective arrangement of Special Low Dispersion (SLD) and aspherical glass elements, this lens has compact dimensions of 83.6mm (3.29") maximum diameter, and 84.5mm (3.32") length. It is capable of taking pictures from a close distance, minimum focusing distance is 38cm at all focal lengths, and has a maximum magnification ratio of 1:5.8. Two Special Low Dispersion (SLD) glass elements are provided for effective compensation of color aberration, which is a common problem with super-wide angle lenses.

One piece of Glass Mold Aspherical and three pieces of Hybrid Aspherical, total four pieces of aspherical lenses offer excellent correction for distortion as well as all types of aberration. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance. The design concept of this lens is especially suitable for the characteristics of Digital SLR Cameras. The high performance inner focus system is particularly suitable for using circular polarizing filters and a petal-type hood as the front of the lens does not rotate. This lens is also equipped with Zoom Lock Switch that eliminates "Zoom Creep". This remarkably compact high performance zoom lens is ideally suited for traveling.

Note: this lens has no built-in motor and will not autofocus on the Nikon D40/D40x, Nikon D60, Nikon D3000, Nikon D3100 or the Nikon D5000 Cameras.

By using a new technology and optical design this lens satisfies the needs of digital photography. Two Special Low Dispersion (SLD) glass elements are provided for effective compensation of color aberration. Four aspherical lenses, one moulded glass type and three hybrid aspherical types, offer excellent correction for distortion as well as all types of aberration.

Great Lens for the price!, March 28, 2008

This lens is Sigma's hidden little secret. My version is extremely sharp, even at F/2.8 and has no focusing issues. It is extremely well made and comes with a lens hood and a case - both of which more expensive Canon lenses don't come with in the box.

Focusing speed is very reasonable and accurate, it has no trouble in low light like some less-expensive lenses. Build quality is amazing. Metal construction, smooth rotation on both the focus and zoom rings, even a zoom-creep lock to help with storage. I have used this on both a Full Frame 35mm camera and a Canon 1.6x Digital SLR and it has worked perfectly

The negatives - inconsistent quality control - some get great lenses, others aren't, although Sigma will happily fix and return the lens within a week or so. 77mm filters are also a pain, especially since they could have used 72mm filters which are less expensive.

Overall, I'd recommend the lens, and is a GREAT step up from the standard lens that comes with the camera.

I have owned this lens for several years and have shot 1000s of photos with it. I really wanted the Canon 24-70mm L lens, but the price was out of the question for me. I ultimately selected this lens because I had read good reviews and I was willing to trade 10mm of focal length for a more compact size, as this was to be my walk around lens. It does weigh more than my Rebel XT, but that doesn't bother me, as it is smaller than the other lenses in its class (Canon & Sigma 24-70mm 2.8, Tamron 28-70 2.8). I have worked with the Canon 24-70mm L, and the Sigma 24-60mm's image quality is remarkably close, if not equal, for a third party lens that costs much less. The autofocus speed is where the real difference occurs, but if you don't work in low light or need a lot of speed, it shouldn't be a problem. You can shoot almost anything with this versatile lens and it will look good (I've shot mostly still life and outdoors), but I think it's really well suited to portraits. If I'm taking pictures at a gathering with this lens, my people pictures always blow everyone else's away. I would reccomend this lens to anyone who wants L quality on a budget and isn't concerned with the slower AF. You won't be disappointed.

Sigma 24-60 mm F2.8 EX DG lens

The large-aperture, wide-angle zoom lens that is an excellent compact companion for digital SLR cameras

Fast f/2.8 constant aperture
Compact Design of just 87mm in length
Minimum focusing distance of 38cm with a maximum magnification ratio of 1:5.8
Two Special Low Dispersion (SLD) glass elements and four aspherical glass elements for maximum image quality
Internal focusing to allow use with circular polarizing filters and a petal shaped hood
Zoom Lock eliminates 'zoom creep'

This is a compact zoom lens with a large aperture. With an overall length of 84.7mm, it is the smallest zoom lens in its class?. It is capable of taking pictures at close quarters, with a minimum focusing distance of 38cm at all focal lengths and a maximum magnification ratio of 1:5.8. It is a very effective lens for close-up photography.

Two Special Low Dispersion (SLD) glass elements are provided for effective compensation of color aberration, which is a common problem with wide-angle lenses. Four aspherical lenses, one moulded glass type and three hybrid aspherical types, offer excellent correction for distortion as well as all types of aberration. The design concept of this lens is especially suitable for the characteristics of Digital SLR Cameras.

New coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance.

This lens has excellent correction for "vignetting", which is a common problem of large aperture lenses. The design ensures sufficient illumination of the corners of the image.
