Sigma 150-600mm | C Pairs Performance with Portability
As you probably know by now, there are two 150-600mm F5-6.3 zoom lenses in the Sigma lens lineup, the Sports, and Contemporary. The Contemporary is the lighter of the two lenses at just over four pounds, compared to 6.3 pounds for the Sports version. The lighter weight of this lens, both in the bag, and in the hands, makes the Contemporary version perfect for on the go nature and outdoor photography. True, you do trade some of the weatherproofing and the totally ruggedized build of the Sports version; but for me, in all but squall-like conditions, it is a tradeoff I am usually willing to make.
I have used both the Sports and Contemporary 150-600mm zoom lens over the past year, and with both lenses, I am very pleased with the focal plane sharpness at all focal lengths—even wide open. The shared DNA and exclusive Sigma features of these lenses—much of which is exclusive to the two Sigma lenses in this category—including the zoom lock switch at all marked focal lengths, the Autofocus speed tuning with the USB dock, custom focus limiters with the USB Dock, 16 zone microfocus tuning with the (wait for it…) USB dock, and the orientation detection panning mode with the Optical Stabilizer place both of these lenses at the head of the pack among long-reach telephoto zoom lenses.
The compact design of the Contemporary version makes it my new go-to lens for outdoor photography. For me and my ways of photographing, the total performance, portability and versatility almost always outweigh the advantages of the more ruggedized build of its Sports sibling.
I am not the sort of photographer that prefers to squat in one spot on the sidelines with a monopod; and I am not the sort of photographer who prefers to sit on a fold-up chair inside a bird blind for hours on end with a gargantuan lens on a gimbal-head tripod.
For me, wildlife and outdoor photography has always been an active pursuit. I hike with my lenses. My favorite outdoor photography days are days when I can cover a lot of ground with a lens slung over my shoulder—at the ready when an opportunity presents itself. (In fact, my single-biggest issue with time lapse photography is the sendentary nature of it, once the cameras are set up!)
The long reach, sharpness, light weight, and lens feature set on the 150-600mm | C make it perfect for me, without ever having a feeling that I am making too great a compromise in terms of reach, range, image quality, and total performance.
The fact that this lens is so portable and easy to hand-hold for hours at a time, and offers such high-quality sharpness, even wide open at 600mm has allowed me to make so many shots that I just would not have been able to make with a bigger, bulkier lens–even with a responsive gimbal tripod head.
I’m just not a gimbal guy. I understand them and can appreciate their value in manipulating big, bulky lenses; but I feel like I’m swimming in wet concrete when I’ve got a lens mounted to a gimbal. My camera and I can’t move as fast and as freely as I want when we’re tethered to a gimbal. I can’t drop down to the ground when a plover skitters right in front of me then pivot to tracking a gull across the morning sun and up and over my head when I’m anchored to a gimbal.
I was a big fan of the 150-500mm lens, but there were a few things on my wish list for an upgrade; and the 150-600mm | C isn’t just an iterative update, it is a sea change. For example the 150-600mm Contemporary lens has a focus limiter (which the 150-500mm lacked); which is so helpful in speeding autofocus response times depending on known subject distances. And the shared DNA and exclusive feature sets of the two Sigma 150-600mm F5-6.3 zoom lenses activated through the USB Dock, such as AF speed enhancements, custom focus limiters, manual focus override, OS preview, and sixteen zone focus tuning, and the unique zoom lock at all marked focal lengths make both 150-600mm lenses incredible updates from the last generation.
And in both out-of-the-box autofocus speed, and with AF-speed priority selected as the custom setting via the USB Dock and Sigma Optimization Pro; the AF response time of the Sports and Contemporary versions is comparable in all my field and controlled situation observations.
I used a high-contrast black and white target at a distance of fifteen feet illuminated with bright, broad, direct light (which was reading around 1/30 F6.3 at ISO 100), and set a Canon 6D to single shot AF, and threw the lens to closest focus distance before engaging AF and again from infinity and repeated both steps ten times. Both the Sports and Contemporary lenses emitted the focus beep to report target lock from close focus and infinity in very similar times. A hard-wired system tying stopwatch start time to AF activation and stopwatch stop time to the focus beep may show some minor variations in the hundredths or thousands of a seconds columns; but in my casual run-through, any variations between the two was negligible.
When I am out and about with the 150-600mm Contemporary; I never feel like I am making an unhappy compromise in terms of total lens performance and image quality. Instead, I feel like I am hiking a couple of miles with a great, lightweight, long-reach lens always at the ready. And over the course of several hours, and a couple hundred or thousand photos in a session, that lighter weight helps limit fatigue and keeps me with eye through the viewfinder for longer spells.
As much as I do love the rugged build of the Sports lens—and will choose this version in rougher weather—the feel of that extra weight does add up over time. Unless there’s pelting sideways rain in the forecast all day, it’s the 150-600mm Contemporary lens I’ve got slung on my shoulder for my wildlife photography outings these days.
