Gary Wolstenholme reviews the bright telephoto zoom from Sigma, the Sigma 50-150mm f/ EX DC APO OS HSM lens. 9 Jan 2014 1041AM by Gary Wolstenholme Sigma 50-150mm f/ EX DC APO OS HSM in Interchangeable Lenses Handling and Features Performance Verdict Specification This telephoto zoom lens for use with APS-C format cameras offers a 3x zoom range equivalent to a 75-225mm lens used on a 35mm camera, a fast constant f/ maximum aperture, silent autofocus and optical stabilisation. It can be picked up for around £720 and is available to fit, Sigma, Canon and Nikon SLR cameras. Sigma 50-150mm f/ EX DC APO OS HSM Handling and Features Weighing around this lens is quite hefty, even though it is more compact than similar lenses designed to cover full-frame sensors. High quality plastics with a matt finish have been used for much of the lens barrel, which provides a good feel to the lens and a metal lens mount adds to the overall robustness of the lens. However, Sigma make no claims about this lens being resistant to dust and moisture. The lens balances well on the Nikon D300 body used for testing, and handling is aided further by the addition of a vertical battery grip. Care may need to be taken if pairing this lens with a more compact camera body as that may result in quite a lens-heavy combination. A HSM motor powers autofocus, resulting in quick silent focus and the ability to apply manual focus adjustments at any time. The manual focus ring is well damped, which makes applying manual adjustments a pleasure. Focusing is performed internally, so the 77mm filter thread does not rotate, making this lens ideal for use with polarising and graduated filters. The close focusing distance of 80cm is fairly typical of this kind of lens. The optical stabilisation system fitted to this lens promises to allow sharp images to be taken at shutter speeds slower than would be possible without the system enabled. With care, sharp images can be produced around half the time with shutters speeds as low as 1/30sec at 150mm, which is roughly three stops slower than the usual rule of thumb would dictate necessary, so long as a couple of seconds are allowed for the optical stabiliser to settle before taking an image. Sigma 50-150mm f/ EX DC APO OS HSM Performance At 50mm, sharpness is already outstanding in the centre of the frame at maximum aperture although towards the edges performance just exceeds good levels. Peak sharpness across the frame is achieved with the aperture stopped down to f/ for this focal length. Here sharpness is excellent across the frame. Similar performance is maintained at 100mm, with excellent sharpness in the centre although clarity falls just below good levels at maximum aperture. Stopping down to between f/ and f/8 results in peak performance as sharpness is excellent across the frame. Finally, at 150mm, there is a slight drop in performance in the centre of the frame at maximum aperture, with performance in the centre approaching excellent levels. Clarity towards the edges of the frame is improved over other focal lengths at maximum aperture, with performance approaching very good levels. Peak performance for this focal length is realised between f/ and f/8, where sharpness improves to excellent levels across the frame. [email protected] [email protected] [email protected] How to read our charts The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges. Averaging them out gives the red weighted column. The scale on the left side is an indication of actual image resolution. The taller the column, the better the lens performance. Simple. For this review, the lens was tested on a Nikon D300 using Imatest. Chromatic aberrations are reasonably controlled, just exceeding pixel widths at 50mm and f/ as well as f/22. This low level of CA should pose few issues, even in large prints, or harsh crops from the edges of the frame. [email protected] [email protected] [email protected] How to read our charts Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software. Apochromatic lenses have special lens elements aspheric, extra-low dispersion etc to minimize the problem, hence they usually cost more. For this review, the lens was tested on a Nikon D300 using Imatest. Falloff of illumination towards the corners of the frame is fairly well controlled. At 50mm the corners are stops darker than the image centre and at 150mm the corners are stops darker than the centre. Visually uniform illumination isn't achieved until the lens is stopped down to f/ or beyond throughout the zoom range. Mild barrel distortion is present throughout the zoom range, with barrelling being present at 50mm and at 150mm. This low level of distortion should be difficult to spot, but if straight lines are paramount, then you'll be glad to hear that the distortion pattern is uniform across the frame at both ends of the zoom range, which should make applying corrections in image editing software pretty straightforward. A deep petal-shaped hood is supplied as standard with the lens, which does a decent job of shading the lens from extraneous light that may cause unwanted flare and loss of contrast. During testing there were no issues with flare and contrast holds up reasonably well, even when shooting into the light. Sigma 50-150mm f/ EX DC APO OS HSM Sample Photos Value For Money The price of around £720 means that this lens is a more affordable and compact alternative to the traditional 70-200mm telephoto zooms. The closest equivalent for Canon cameras in terms of specification is their 70-200mm f/ IS USM II lens, which apart from the slightly longer focal length range sports virtually identical specifications, but is currently around £1950 to buy new. It is worth noting that the previous version of this lens is also still available from some retailers at a more manageable £1000. Canon users on a budget may also consider the EF 70-200mm f/4L lens, which can be picked up for around £515. However, this lens is a stop slower throughout the zoom range and lacks optical stabilisation. Nikon camera owners looking at their 70-200mm f/4 VR lens, which costs around £950 may also consider this offering from Sigma as it is a stop faster throughout the zoom range. Nikon's 70-200mm f/ lens costs around £1580. Tamron also produce a 70-200mm f/ lens with optical stabilisation, which costs around £1030. Sigma 50-150mm f/ EX DC APO OS HSM Verdict This lens is a solid performer, capable of delivering high quality images with decent sharpness, even if the performance it delivers isn't mind-blowing in any way. The lens is well specified, and the value for money it offers holds up well when the price of competing lenses are taken into account. Those in the market for a serious f/ medium telephoto zoom for their APS-C format Canon or Nikon DSLR would do well to consider this lens.

They somehow managed to adjust the focusing, but after using it for a year I sold it, because the image quality of Sigma 50-150mm was not impressive. The only plus is excellent HSM motor. Tokina 50-135mm f2 is just way better than this problematic, bad focusing, average IQ Sigma... reviewed April 21st, 2009 purchased for $600 9 out of 10 points and recommended by Ulan 3 reviews Good build quality, fast and quiet autofocus, sharp, excellent contrast, light, minimal distance focusing is more than 1 meter I was rather worried to read about frontfocusing, chromatic aberration, softness at f/ Maybe quality differs from one lens to another, but mine is quite OK. Images are crispy, contrast very good, excellent sharpness at almost all the focal range especially at aperture smaller than f/4 and f/ HSM autofocus performs very well. Zoom is light and easy to carry. Build quality very good. Focal range is ideal for APS-C, more convenient than a 70-200 mm. I am very pleased with this lens, a jewel. Just a pity it has no image stabilizer. reviewed June 28th, 2007 purchased for $940 10 out of 10 points and recommended by tdotduffman 10 reviews Zoom range, aperture, build and image quality, weight Focus accuracy unit specific, mine fixed by Sigma Service Extraordinarily sharp and contrasty when the focus is on. My particular unit front focuses by about an inch to two inches when shooting closer than 2-3 meters. However, the HSM allows for a quick touchup. This is fine when one has time to shoot, but not in close action with large apertures where the DOF really necessitates accurate placement of the focal plane, such as wedding receptions. Perhaps Sigma calibration will help, in which case I'll report new findings. A little CA in tricky situations. I should note that though the amount of blur caused by misfocusing still produces better images than certain cheap lenses, it's frustrating because manually tweaking the focus shows what this glass is really capable of, even at 150mm. Used on a Canon 350D and 400D. Setting AF to the back button rather than the shutter release can facilitate the manual tweaking process when taking many pictures at the same subject distance. eta I sent the lens in to Sigma for service. Focus is now spot-on, making f/ a real pleasure to use with this tool. Also works splendidly on a Canon 30D. reviewed May 18th, 2007 purchased for $680 8 out of 10 points and recommended by silverbluemx 16 reviews Light, fast, 50-150 range is more than 70-200 equiv, construction. Front focussing issue on my 300D, a little soft at 150mm wide open. I had the occasion of shooting tens of pictures in a store with this lens and my 300D. On many test shots i found that the lens front-focussed at any focal lenght. On the point where it was actually focussed, it was very sharp at f/ from 50mm to about 135mm and then slightly soft at 150mm. At f/4 and above, sharp everywhere at least in my test conditions. Build quality is very good, and as an equivalent of the 70-200/ it is quite small and light, has a nice shape, and focusses silently and fast enough. Focal range is nice 50-150 on a cropped sensor means the same field of view as an 80-240 which is more than the big and heavy 80-200 for full frame. On a price point it is a good alternative to the 70-200/ non IS and also it is wider. I think that on more recent bodies such as the 400D or 30D with more advanced autofocus than my 300D the front-focussing problem will go away, so it's a very good choice for those in my opinion. reviewed January 11th, 2007 10 out of 10 points and recommended by Matthew Saville 21 reviews build quality, image quality, fast apeture vignetting, close-up softness This is my most recent lens purchased, obviously since it just hit the shelves a couple months ago ...and I really love it. I also have the Sigma 150mm f/ macro, which is legendary for it's image quality, and upon testing I've found that the Sigma 50-150 at 150mm is on par by f/8 close up, and sooner near infinity. The lens is definitely not built to shoot close up wide open like the 150mm is, the 50-150 exhibits heavy vignetting and sever image softness at 3 ft. focus distance. The sharpness is drastically improved by f/ though, and the vignetting also goes away a lot by stopping down or backing off from 150mm a little. The way I convinced myself to be happy with this performance is by telling myself that at 150mm on an APS-C DSLR, I'm actually at 225mm field of view, which is 25mm extra compared to a 70-200mm lens on an FF body. 135mm is what, on my D70, would roughly equal 200mm, and at 135mm the Sigma 50-150 does great. So I highly recommend this lens! -Matt- reviewed December 29th, 2006 purchased for $690 7 out of 10 points and recommended by aalto 12 reviews 50-150 range, fast, weight, Lens hood Vignette I havent used this lens extensively yet, so consider this review a first impressions one. The 50-150 range on a APS-C size camera is a incredibly suitable range for those of us who are not dependant on the 150 to 200 range of the photojournalist workhorse zooms. I have been using equivalent zooms that go up to 200mm and as for my personal needs, I noticed that I wasnt actually using the latter 50-60 mm that often, so when sigma announced this lens with fast focusing and half a kilo or more less weight than the competition, I ordered right away. And so far I have virtually nothing to complain about. The weight allows me to use the lens hand held for a couple of hours before my wrists are tired, event though the weight distribution on a D70 is a bit awkward, you get used to it after a while. The lens hood protects the lens really well, and that enables me to just leave the front cap off. Even with the lens hood on, the lens is roughly the sam diameter along the lenght, whivh means that it goes in and out of a camera bag fast without clinging to all the other stuff in the bag. As to the optical quality, the lens does deliver. There is little CA to my opinion, but I havent done any formal tests yet. This is shockingly... not a lens for architecture, but distortion is generally not a problem. There is however some vignetting, though very smooth and easy to remove, when using the lens wide open at 50mm. A good lens if you dont need the 150-200mm range but still want something thats fast, light and got focus speed. reviewed December 21st, 2006 purchased for $750 9 out of 10 points and recommended by studio5photo 1 reviews Well made both optically and mechanically Some concern about front focus issues. I have had this lens for only a week but have done several tests on it. The sharpness is excellent at 50mm and 100mm, and very good at 150mm. The corner sharpness is better than my previous lens which is the Nikon 70-210 F4. Center sharpness is a little worse. This is comparing the Nikon at F4 to the Sigma at I find the colors to be excellent, best I have seen, much better than 18-70 kit lens for D70. I measured the focus speed again the Nikon 70-210 F4 and the 18-70 Kit lens. Ends up closer to the 18-70mm lens, but the difference between the HSM, AFS and older screw drive was much less when actually measured than what I thought just by listening to them. Overall, a well balanced winner. I love the 50-150 length as well, much more natural than the 70-200 given a digital camera's crop factor. Posted some pictures here UPDATE 1/18/07 - I just found out that this lens and my other HSM/AF-S lens do not like cold weather. I left both outside in my car for about 5 hours at 30F freezing. My 50-150 would not focus, nor would my 18-70mm Nikon AF-S lens. My screw drive 50mm would. Consider this before purchasing. I still love the lens by the way.

For me it's superb because the existing 70-200 lenses are much more expensive and the picture quality is not better and you get 50mm instead of 70 and this can be critical for some sports when the hall is not very big.
