Sigma 120 300 sports review betting what does round robin mean in betting sigma 120 300 sports review betting


This eliminated any harsh shadows to contend with, but made the handheld exposure more challenging. I kept the shutter speed just fast enough to stop the excited subjects' motion. Again, that story was from the arrival of this lens' predecessor, but the new model is at least as capable handling that situation.

And switching cameras is still not as fast as zooming out with the As I have said several times before, taking full advantage of this added zoom range benefit requires another level of skill when shooting fast action. This is no different with this Sigma zoom than from any other zoom lens, but many of us are using long primes for sports action. The limitations of a prime lens make them easier to use.

But, all else equal, a zoom lens will deliver significantly more and better-framed images. The daisy examples shown in the comparison were taken at a near-minimum focus distance. Add the telephoto focal lengths mean that sports are a primary target for the OS.

Another popular subject for this lens, especially with APS-C 1. The mm focal length range also makes this lens a very capable indoor event and portrait lens, but the weight of this lens will challenge significant handholding durations. Most are going to be happier using this lens mounted to a monopod or tripod when shooting events - and these supports can limit event and portrait shooting flexibility.

If choosing to handhold this lens, OS Optical Stabilization comes to the rescue. Thus, I did not retest this OS implementation's full capabilities, but of course used it during evaluation of this lens. And OS remains a valuable lens feature to me. The 's OS is well behaved viewfinder image remains steady during OS startup and features mode 1 normal and mode 2 panning options. With Sigma Dock compatibility, this lens' OS can be further configured to one of three settings described by Sigma as: Dynamic View Mode — This mode offers a recognizable OS effect to the image in the viewfinder.

This helps to ensure the composition of images quickly. Standard — This is the default setting. The OS effect is well-balanced and suitable for various scenes. Moderate View Mode — This mode offers an excellent compensation of camera shake, and achieves very smooth transition of the image in the viewfinder. The composition of the image remains natural even when the angle of view keeps changing. Sigma claims 4 stops of handholdability from this implementation of OS. The narrower angle of view means that subject details will cross more sensor pixels with the same amount of movement as when using a wider angle lens.

This is about a 3. IS On IS Off There is no question that this lens can be handheld and that OS aids in doing so — but such use will be avoided most of the time by all but the strongest photographers. The big question is usually "How big is the difference? With the OS "S", that difference has been very significantly reduced.

Roger, after tearing down both OS versions of the , said it appeared that elements in these lenses could be interchanged. The optical design seems unchanged. Regardless of the reason, test results show that the OS "S" lens is a significant upgrade optically. Many are not going to find the difference in image quality reflected in the difference in price. The Sigma costs more in this case, but the needs an extender to get out close to mm. You also may think "mm is not mm".

This would be a good time to mention that specified focal lengths are not always exact - especially on zoom lenses. Basically, the difference between the focal length of these lenses is not very significant. Use the Image Quality tool link at the top of this review to see the differences between this lens and any other tested lenses at your choice of focal length and aperture. But even this change is mild. Wide open full frame corner shading ranges from a very mild 1.

Overall this lens shows very little vignetting. As usual, APS-C format sensors will not see much of a full frame lens' shading. CA Chromatic Aberration is another image quality defect mm S lens owners will not need to worry about. Very little CA can be found in images from this lens.

Zoom lenses usually have barrel distortion at the wide end and pincushion distortion at the long end. This zoom lens, while not completely distortion free, definitely performs well in this regards. At mm, this lens is nearly distortion-free. A slight amount of pincushion distortion becomes apparent in the midrange and becomes mild at mm. Overall; this is a very good showing from a zoom lens. However, it shows a marked improvement over the prior version of this lens by showing surprising little flaring even with the sun in the corner of the frame.

As shown in the sample photos shared above, the OS can deliver a strong background blur and the quality of that blur termed "bokeh" appears to be very nice. With 9 aperture blades, this lens will create 18 point stars from OOF Out of Focus specular highlights when stopped down. With the large lens hood and hefty tripod ring attached, the whole assemblage tips the scale at just over 8 pounds!

The new TSC is similar in texture and strength to metal, but is more suited for tough weather conditions and temperature changes than polycarbonate plastics it features similar thermal characteristics to aluminum. Sigma says it's designed to allow for high-precision construction and combines well with other metal components.

We're not sure if the entire barrel and hood are constructed with the new TSC material or if there is a mixture of metal and TSC components, as it all feels a lot like metal to the touch. Regardless, the lens feels extremely solid, and the build quality is excellent. When it comes to hand holding this lens, it's definitely not your average walk-around lens! The large glass elements in the front shift the balance of toward the front, and thankfully the tripod foot includes 3 mounting holes, allowing users to properly balance the lens on a tripod or monopod depending on the size and weight of their camera body, and whether they're using any other attachments like teleconverters.

While hand holding this lens is not impossible, it's large and heavy, and using a monopod at least is highly recommended if you plan on shooting for any length of time. You'll also find attachment points on the tripod ring itself for its own neck strap. Like most lenses that feature a tripod foot or ring, the tightening knob allows you to rotate the camera and lens into a vertical orientation quickly without having to fiddle with your tripod head, avoiding potentially unstable tripod arrangements given the lens' size and weight.

The Sigma mm lens' metal-like construction has a smooth, matte black finish. Gone are the days of Sigma's old rubberized black coating. It looks and feels great, although it's very bulky and can be a bit unwieldy if you're not used to lenses of this size. Compared to the previous version, Sigma states that this model is dust and splash-proof, but not fully waterproof — more like "weather-sealed. Inside the big black barrel sit 23 lens elements in 18 groups, two of which are FLD glass elements, which Sigma claims are optically identical to fluorite glass.

The lens also features a 9-bladed aperture. The separate focusing and zooming rings are wide with large rubber ribs for an easy grip. The zoom ring is larger at about 2. The focus ring, on the other hand, is smaller at about 1. The zoom ring is farther away and the focus ring is closer to the camera.

Both rings rotate very smoothly, although the zoom ring takes a bit of effort to turn almost requiring your whole hand. I found the zoom ring a bit awkward to rotate if you are hand holding the lens, particularly with the tripod foot attached, as you tend to rest your hand under the tripod foot, and it takes some oomph to rotate the zoom ring.

The focus ring, however, is buttery smooth and easy to turn. The focus ring will rotate all the way around the lens and has soft stops at close and infinity distances. The zoom ring turns less than 90 degrees. As with focusing, the front element of the lens neither rotates nor extends when zooming, which allows for easy use of screw-on filters like circular polarizers the Sigma mm takes mm filters; no option for a drop-in filter.

Other exterior features include a focusing distance window and marked focal lengths of mm, mm, mm, mm, mm and mm. This updated model also sports a redesigned lens hood, which feels similar in construction to the barrel either TSC or metal.

The lens hood locks on to the front, bayonet style, with a locking screw and adds about 4. Sigma indicates that the new mm lens features new mechanics and improved performance compared to the old model, and the new version does feature cosmetic changes in the barrel construction, and adds features like weather sealing and a new AF algorithm for smoother autofocusing. They both also have 9-bladed apertures, HSM focusing and image stabilization.

The big difference is price. For the weigh-conscious, the older model is also lighter at 6. While we haven't tested the older models, reports are saying the new version is optically superior. The two major downsides are a you are limited to the single focal length and b the price. The new Sigma mm lens is the first "Sports" model in Sigma's new Global Vision line of lenses.

The addition of image stabilization makes it a no-brainer for sports and action photographers that shoot in all sorts of environments and weather conditions. It's well-suited outdoors, for football or baseball season or indoors, courtside at a basketball game. Nature and wildlife photographers should take a look as well.

The zoom really makes this a very versatile lens.
