Distortion guide. Vignetting guide. Water-repellent, Antistatic type. Protector is developed to protect the lens surface from dirt and dust as well as scratches. It is an ideal filter for regular use as it is completely colorless so does not affect color reproduction. Normal type. UV Water-repellent, Antistatic type. UV filter prevents the bluish tone that generates when the weather is fine, by absorbing ultraviolet rays. It is effective in most situations, such as landscape, portrait and general photography on a sunny day.

It is also an ideal filter for regular use as it is completely colorless so does not affect color reproduction. PL Water-repellent, Antistatic type. Circular PL filter removes the reflection of water surface and glass windows, and increases the contrast in landscape photography. Large aperture standard zoom lens with a minimum focal length of 17mm, designed exclusively for digital SLR cameras and incorporating Sigma's original OS Optical Stabilizer.

Super Multi-Layer Coating. Sigma's own unique OS Optical Stabilizer technology. With Optical Stabilizer. No Optical Stabilizer. Superior peripheral brightness. Fast and quiet AF. Minimum focusing distance of 28cm, Maximum magnification ratio Covering a wide range of focal lengths from 17mm.

Rounded diaphragm. Compact construction. Inner focusing system. Lens Construction. Angle of View. Number of Diaphragm Blades. The mm focal length range falls squarely in the recommended general purpose lens focal length range for the APS-C sensor format DSLRs it is compatible with. This focal length range delivers that same angle of view that a Here is an example of what this focal length range looks like.

After a long, cold winter, the bright new growth on the trees was looking gorgeous to me. The mm focal length range is nice. It works great for around-the-house shots inside and out , for landscapes, for full body and head-and-shoulders portraits, for close sports and for a huge range of other uses.

For many, their first general purpose lens is the one available in-the-box with their first DSLR. While the kit lens is very economical, it is also the source of many emails I receive - especially when being used indoors without a flash. If there is any subject movement, the max aperture available on these lenses is not wide enough to allow the action to be stopped - resulting in motion-blurred images.

This aperture difference can translate into a big difference in your image quality. There are many lenses with longer focal length ranges available. As I indicated already, a wide aperture is a great advantage for a lens to have. If your subject is not moving, the Sigma 's 4-stop-rated OS optical stabilization will be a great help in achieving sharp handheld shots in low light, in the wind, on unstable footing, on a boat I have some sharp shots taken at.

This is, again, a net 3-stops of assistance from OS. Stopping down does not significantly affect the center of the frame image quality - nor does it need to. The Sigma OS controls vignetting quite well. With a wide open aperture, expect to see about 1. Some chromatic aberration is noticeable in the corners in the wider half of the focal length range. As a generalization, CA is worst at 17mm and slowly improves through the balance of the focal length range.

The amount of CA exhibited is not unusual for a lens in this class. The Sigma OS shows varying amounts of flare over the focal length and aperture ranges, but overall, it is a decent performer in this regard. Bokeh background blur quality generated by the 7-blade aperture appears to be mid-grade. The odd number aperture blade count will create 2x the number of light rays as aperture blades 14 from points of light when a narrow aperture is used even blade counts deliver 1x light rays.

At 17mm, the Sigma exhibits a noticeable bulge-in-the-middle barrel distortion. This distortion smoothly transitions to mild pincushion distortion at 50mm with approximately 25mm being the near-distortion-free transition focal length. Though reasonably quietly, the generates some gear noise during AF. Focus accuracy has been the biggest issue I've encountered with this lens. I've had many shots misautofocused for no apparent reason - especially in AI Servo mode.

Focusing is internal - the front element does not extend or rotate. The focus ring is nicely sized and in the position I prefer - as the front-most ring. The table below reviews a large number of general purpose lenses' minimum focus distances and maximum magnifications. With an 11" mm MFD and a. And, these figures are good enough for many close subject needs. However, that is not the end of the close-up story. The tested MFD for this lens is 9. MFD testing uses manual focusing - and this lens indeed manually focuses closer than it will autofocus.

I have not been a big fan of Sigma's matte finish - especially because it readily shows fingerprints and dust. The good news is that only the edges of the zoom and focus rings retain the conventional Sigma finish. The hood and mount areas, the main lens areas not covered by rubber zoom or focus ring, are a much nicer my opinion of course smooth finish.

The focus and zoom rings are very smooth with no play. The zoom ring has an ideal amount of resistance while, as I indicated earlier in the review, the focus ring is slightly too easy to rotate. Like all other zoom lenses in its class, the Sigma OS extends when zoomed to its longest focal length. There is very little play in the extending portion of the barrel. My purchased-retail copy of this lens does not exhibit gravity-zooming behavior, but a lock switch is provided to assure the lens stays retracted at 17mm.

These switches are located close enough to the lens mount that they are not uncomfortable during use, but they are easy to find with your left thumb.

The relatively small lens hood is large enough to help keep fingers and other objects from touching the front element. The Sigma center-and-side-pinch lens cap is very nice and is easy to install or remove with the hood in place. The Sigma OS is in the middle of its class in the size and weight categories. I find a lens with this size and weight to be easy to take with you, comfortable to use and to have enough mass to be stable.

The 77mm filter size is not small, but it is very common - making the sharing of certain filters easy no step-up rings required. Let's review some outdoor results from a selection of similar lenses.

Most of us need at least one general purpose lens - and the focal length range is usually my primary qualification for such a lens.

I was waiting for this lens to become available as I was looking for this type of xerox 108r01490 for shooting weddings. The preceding is actually a good descriptor for performance in the other focal lengths, with a single noteworthy observation. Zoom turns the wrong way, that's quite poor on their part. And does it merit xerox 108r01490 closer look at full price if you already own a kit lens of a similar focal range? Working round lack of full-time manual focus is a little annoying, but I got used to it fairly quickly. Our staff members must strive for honesty and accuracy in everything they do.
