## Description

Product Description Sigma 17-50 mm F2.8 EX DC OS HSM. Fig. 17-50 mm F2.8 EX DC OS HSM. Example image of 17-50 mm F2.8 EX DC OS HSM. Our bright EX standard zoom lens meets all expectations of such a representative of this class. The lens is ideal for taking snapshots, landscapes, group photos, architectural shots or travel photography. The consistently high light intensity guarantees optimal light output and thus allows short shutter speeds that minimise the risk of blurring. The HSM (Hyper Sonic Motor) ensures fast and quiet autofocus and lets you react quickly. The SML (Super Multi Layer) coating prevents ghosting caused by reflections on the sensor surface and delivers images with balanced colour balance. Thanks to the internal focusing, the front lens does not rotate when focusing, so nothing stands in the way of the use of a tulip-shaped lens hood and a circular polarising filter. This bright lens has been developed for digital cameras with APS-C sensor and features Sigma OS (Optical Stabilizer) technology, which allows up to approx. 4 time levels longer from your free hand without shaking your pictures. If the camera system is already equipped with image stabilization, the Hybrid Optical Stabilizer of the lens can be used in place, which also stabilizes the viewfinder image, allowing better control of sharpness and image build-up. Two FLD (F low dispersion) glass elements, whose imaging performance is equivalent to that of fluoride glass, as well as two blank-pressed glass lenses and a hybrid asphere effectively eliminate all colour defects. The lens has an excellent light output and delivers sharp, high-contrast images at all focal lengths even in the open aperture. Thanks to the 7 slats, which allow an almost round aperture, a very pleasant bokeh is created outside the sharpness level. Due to the internal focusing, the front lens does not rotate, which allows the use of a tulip-shaped lens hood and the convenient use of a polarising filter. - Unique design. Exclusive quality, non-slip design, elegant finish - these are the features of our professional rail. The EX symbol characterizes our sophisticated lens series. In addition to the high quality standard, these products are characterised by exclusive focal length ranges and high light intensities. The excellent performance features of Sigma EX lenses, uncompromising design, perfect handling and excellent durability meet the demands of photographers at the highest level. EX lenses - the better choice. - APS-C sensor suitable. First of all, the coating technology and the construction of the DC lenses, whose calculations are based on digital demands, largely prevent light reflections from the sensor on the backward objective lens. In addition, the DC lenses offer impressive image quality despite their low weight and compact size, which meets the demands of digital SLR cameras. These lenses are limited to the angle of view that is only used by most DSLR cameras anyway – to the angle of view of the cameras with a sensor size in the so-called APS-C format. The sensors of most digital SLR cameras are smaller than the 35mm film with its 24x36mm format and have the dimensions of the APS-C film format. Therefore, you cannot use the DC lenses on a full-frame digital camera or an analogue film camera. They inevitably received shadows in the corners of the picture. By limiting the image angle to this APS-C format, it is possible to achieve a considerable image performance with reasonable design effort. The less complex design affects the size and weight of the DC lenses. The lower effort ensures significant cost savings, which we pass on to our customers. With our DCs you get powerful lenses at extremely attractive prices. Left with OS, right without OS When DC series lenses are used on 35mm SLR cameras or digital cameras whose image sensors are larger than APS-C format, vignetting occurs in the image. - Optical stabiliser. Sensors in the lens detect camera movements that can cause blurring in the image, and when combined with a movable suspended lens element, these movements are compensated. As a result, your photographic possibilities are greatly increased when shooting hands free. Stabilized lenses allow you to shoot from your hand 3-4 exposure levels longer than usual. On camera models that are already equipped with a stabilizer, you can choose whether to use the stabiliser of the camera or the lens. Stabilizers in the lens always have the advantage that they also provide you with a stabilised viewfinder image. So nothing stands in the way of an accurate assessment of the image and an exact use of focus. MTF Chart A motor with speed. HSM lenses use a motor driven by ultrasonic waves. This technology gives you a very fast, accurate and almost silent mode of automatic focus. Two different types of HSM ultrasonic drive are used in our lenses. On the one hand, the HSM ring motor, which is mainly installed in the high-quality EX lenses. This HSM drive allows you to manually intervene in the AF operation at any time. On the other hand, an HSM micromotor is mainly used in compact lenses, the so-called all-round zoom lenses. Manual intervention in AF operation is not possible. MTF modulation transfer function. The MTF (modulation transfer function) is one of the measuring methods with which the performance of a lens and its contrast behavior can be determined at different spatial frequencies. The horizontal axis expresses in millimetres the distance of the centre of the image to the edge of the picture, the vertical axis expresses the contrast value (highest value is 1). The information for 10 lines/mm reflects the contrast behavior of the lens (red lines), the values for 30 lines/mm express the resolution (green lines), each with the aperture open. Lines that run parallel to the image circle diameter are called sagittal lines (solid line), transverse lines are called tangential lines (dashed line).

Review: Expensive but I cannot fault it - I wanted a zoom lens to replace the 18-55 kit lens on my Nikon D5100. I also have the Nikon 35mm 1.8g, but in practice I tended to use the zoom lens more despite the lower image quality. I was looking for great image quality and sharpness with effective stabilisation. The wide constant aperture was a bonus rather than a necessity. This lens was recommended to me by a wedding photographer who chose it instead of a mega-expensive Nikon. I chewed over this for ages - I considered Tamron equivalent both without VC (cheap) and with (not as cheap but not as good?), also the bargain Nikon 50mm 1.8 for image quality. The Sigma is very expensive in absolute terms for an enthusiast like me, but in the end the reviews swayed me. I had some reservations about what I had heard regarding variations between samples, but I decided that I would test the lens extensively on arrival. If there were any shortcomings I would simply use desertcart's excellent return system until I found a good one. After the 30 day mark there would be Sigma's 3 year guarantee to fall back on. I am pleased to report that this has not been necessary - it's a good 'un. The lens arrived in great condition - it is solid and heavy and feels like a professional item should. In use the weight helps dampen vibrations and is a positive thing. It resembles my Sigma 10-20 EX in looks and feel. It takes good images! I have compared it in "blind" tests with my other 2 lenses at 35mm on a tripod. As expected the Sigma wins with the 35mm close behind. In particular the Sigma is much better than the 35mm at controlling CA. Although worthy, the kit lens is beaten hands down, especially towards the edges of the frame. The AF works very well, I tested this and found it was bang on - more accurate than my manual focussing skills. I would give this lens 5 stars if it was less expensive, but I guess you get what you pay for. This lens ticks all the boxes - great build and image quality so far, with stabilisation and useful zoom. I think however that if you can adapt to framing without zoom and have steady hands that a couple of Nikon prime lenses could do some of the job, possibly for less money. The Sigma gives good results at the 17mm end, which I find useful. I am very happy with this lens and would buy it again.
Review: An awesome entry level lens for APC-S cameras - I have been using this lens non-stop for the past 3 years for both photography and film making and I have to say for the price and performance it’s one of the best lenses to use for an APC-S camera body. I was so confident in my initial choice of the lens I bought two, which I use for different functions and it satisfied my needs during those times. Just so you are aware I use a D5500 body along with it, which is known for having 1.5 x crop factor. With that in mind here are the pros and cons. PROs: - It’s versatile as an all-round photography lens. The 17-50mm on APC-S is the focal equivalent to a 24-70 on a full frame camera. At 17mm It is awesome for landscapes/wide angle shots, whilst the 50 mm will behave quite like a 70mm prime for portraits. - Uses a 77mm thread for filter which is common for most fixed aperture lenses - Between the 35-50mm range the lens offers great bokeh for portraits. - Having a fixed f/2.8 aperture is brilliant for low light photography and filmmaking and it feels like you have multiple prime lens. It allows plenty of light onto the camera sensor to keep the ISO & shutter speed at low values. - The auto focus is fast and silent on the D5500 at all focal lengths, and the optical stabilisation is great for capturing sharp images that are stationary or moving. 6. Focusing is pretty accurate on wide to medium shots and is useful for manually focussing at infinity if landscape photos are your niche. 7. The addition of a lock mode is great to eliminate any breathing when in use or aiming down. 8. At f/4-5.6 the images and video produced is super sharp, which is where you should be working from most of the time. CONs: 1. The lens is a lot heavier and bulkier than other kit lens to compensate for the fixed aperture. 2. The build quality takes a hit due to price reducing. Some people might like the finish others won’t. 3. You can feel and hear the internal components move around if you shake the lens and the supplied lens hood can easily fall off. 4. The zoom and focus rings are arranged opposite to normal NIKON lens, which can be jarring to new users. 5. The manual focus range is extremely limited especially in close up shots, so be aware of the minimum distance you can rack focus to whether in manual or auto. 6. At f/2.8 on all focal lengths you can notice the image sharpness gets a bit soft and there is a subtle vignette at the lower focal length range. 7. The focal length zoom is an external rather than internally function which isn’t great for filming unless the camera is station at all times. Considering most people who are looking at this len probably are starting out with either/both the 18-55 Nikon kit lens and Tamron 70-300 VC, this of course is the natural progression to advancing your photography. Along with the NIKON 35 mm and 50mm prime lens this would be among my go to lens if I started again from scratch. As a film maker or vlogger, I will admit it might not tick all the boxes and that’s in part due to the negatives addressed. If you really are on a tight budget by all means go for it, but if you’re going to do it professionally I’d often recommend saving the money and getting the sigma art 18-35mm f1.8 and future proof the investment. Regardless of the negatives I still love this lens as it is overall a good purchase, it’s ideal for travel being an all-around lens and can produce truly stunning images with minor issue being fixable in post. I absolutely would recommend this.

### ⭐⭐⭐⭐ Snags compared to Nikon original lenses
*by S***T on 10 April 2019*

Great lens BUT I found some snags I was not expecting. I use this lens on a Nikon D7200 I love... Sharper than anything comparable I could find (see DXO Labs tests for info). Needle sharp at f3.3 wide angle and f2.8 zoom. Good light transmission makes it great for low light photos. Great value compared to Nikon. Sharpish at f11 so okay for landscapes. Not so keen... Can't switch from auto to manual focus durunh a shot without first switching on manual. If hand accidentally touches focus ring then it hinders auto focusing. Zoom ring works opposite way to Nikon lenses which feels odd. Flare can be a slight problem, more so than with Nikon originals where I find a lens hood unnecessary. Focus tracking of a person walking or running towards the camera works amazingly accurately with Nikon lenses but not with this lens. Perhaps the focus motor is too slow. In bright sunlit high contrast scenes with this lens the camera over exposes by about half to one stop which burns out highlights. That does not happen with original lenses. Overall, I am a tad disappointed but still rate it a great lens for the money. One last thought, the lense I received was a grey import with a 1 year warranty instead of the 3 years Sigma UK offer.
