Sigma 745101 150 - 600 mm F5 - 6.3 DG OS HSM Contemporary Canon Mount Lens, Black

Product Information

Again, with an APS-C camera body, distortion with this super-telephoto is not seen. Full-frame cameras will likely have a little bit of pin cushion distortion, but I wouldn't expect enough to cause a hit to image quality when adjusted in post-processing. Sigma calls their vibration reduction system Optical Stabilizer. Sensibly, they don’t make any marketing claims with this lens that it will give you an extra such and such number of stops. And in my experience, it simply doesn’t work as well as the systems on other lenses. It wouldn’t surprise me if they used an older, cheaper generation of OS technology on this lens, but I don’t know that for sure. The advantage for warranty goes to Tamron, which offers a 6 year one,compared to 4 years with the Sigma. Still, in my opinion, both lenses are well constructed, and I am not convinced how much of an advantage that is, as most warranty issues show up early on. 1.4x Teleconverter To identify which is best among Sigma art, sports lens, and contemporary, I’ve conducted in-depth research in reviewing all the lenses. The results are pretty surprising.

But I do have to point out that even without weather sealed lenses, I've only once had issues with a lens getting dirty inside. The autofocus is excellent, though you'll need to make sure your camera is set up in the optimal way to take advantage of it. The build quality of the lens is also impressive – while no one is going to pretend this is a lightweight lens, it handles well, with tactile zoom and focus rings and a series of on-body controls for functions like AF speed, stabilization intensity, and in a new addition for the mirrorless version, Zoom Torque control to adjust the resistance of the zoom ring. The tripod foot also works as a handle making it easy to carry this lens and/or your camera together. I’ve conducted experiments with my Sigma 150-600 Contemporary lens during my adventure shoots. Through these, I’ve discovered some crucial tips to enhance the sharpness of my photographs.

Summary

Zooming to 300mm results in excellent sharpness in the centre of the frame with very good sharpness towards the edges at maximum aperture. Peak performance is at f/8, where sharpness is excellent in the centre, and not too far behind towards the edges of the frame.

This lens will work quite well for casual sports or wildlife photography. But if you’re earning income from those types of shooting and your budget extends to it, the other model that Sigma puts out, its 150-600mm f/5-6.3 DG OS HSM Sports Lens, offers faster focusing and better optics, but also comes in a larger, heavier lens with a higher price tag. What’s in the Box? Sigma advertises both version of this lens as being “dustproof and splashproof,” but if you read further into the technical specs of these lenses, some questions arise. When carrying your camera with a large lens such as these 150-600mm lenses, it’s best to hold them by the lens rather than your camera. These lenses weigh much more than your camera and can put a lot of stress on the lens mount if carried by the camera. Likewise, when mounting on a tripod, always use the tripod collar to reduce stress on your camera’s lens mount (it is better balanced using the collar and won’t be front heavy). ConclusionThat lens has good optics, but is so heavy that it's impossible to shoot without a tripod and gimbal head.

Either way, it would appear from Sigma's marketing materials that there is at least some amount of better weather sealing than the contemporary version. NOTE: Beforepurchasing the 1.4x TC, make sure the camera will autofocus at f/8. Many entry model DSLRs will not autofocus above f/5.6, so while this bundle may fit those cameras, manual focus will be necessary. Other models may only autofocus on the center focus point, and still others may have a limited number of focus points with the 1.4x TC. With the lens set to its maximum aperture, there is significant light fall-off in the corners at both ends of the zoom range. Stopping-down to f/11 virtually eliminates this. There's very little distortion to worry about.Sigma divides its Global Vision lenses into three separate categories. Contemporary lenses aim to keep the size and weight down to easily manageable levels, Art lenses go all out for maximizing freedom of creative expression, whereas Sports lenses (as their name suggests) emphasize speedy performance. When it comes to build quality, Contemporary lenses tend to have a more consumer or prosumer feel to them, where as Art and Sports lenses have a more pro-grade construction. But if you stop down to f/7.1 or higher and do the testing, the difference between these lenses is even tighter. I'd use a 105mm B+W single-coated 010 UV filter to protect this lens. You can pay more for a 105mm B+W multi-coated 010M UV filter or a 105mm Tokina dirt-resistant protective filter, but the difference is in fancy coatings that have a big effect on price with very little effect on pictures. Detailed specifications for the lens, along with MTF charts and other useful data can be found in our lens database. Lens Handling and Build Quality C: Sigma’s “Contemporary” series. Basically, it distinguishes it from its “Art” and “Sports” ranges. Overall, the Contemporary series lenses are more designed for general everyday photography, with their own combination of price, optical performance, speed, portability, and versatility. The Art series leans more heavily on optical performance and is less worried about things like focusing speed. While the Sports series aims for, well, sports, but also nature and wildlife photography. The categories are more useful in marketing than in practice, but when there’s overlap in the focal lengths, the Art and Sports options tend to be more expensive, with the Contemporary series aiming more for the enthusiast end of the market.
