In the review, the Sigma DC 18-50mm 1: 2.8 EX MACRO HSM lens I will abbreviate - Sigma 18-50 / 2.8 Macro. This review shows the version for Nikon DX series cameras.

Sigma DC 18-50mm 1: 2.8 EX MACRO HSM

In short

The Sigma 18-50 / 2.8 Macro is a professional high-aperture zoom lens of universal directivity with a very convenient range of focal lengths. Sigma 18-50 / 2.8 Macro - Alternative for Original Super Lens Nikon 17-55 / 2.8G.

Sigma 18-50 / 2.8 Macro (especially the HSM version) is a very attractive solution for little money. Probably the most balanced high-aperture station wagon without a stabilizer for cropped SLR cameras of different brands.

Choosing a versatile fast zoom lens is a very important step in the lives of countless photographers, especially those who have to shoot a variety of subjects. The Sigma 18-50 / 2.8 Macro can be a reliable assistant for such tasks.

Sigma DC 18-50mm 1: 2.8 EX MACRO HSM

Version + - 'HSM'

The Sigma 18-50 / 2.8 Macro lens, introduced on September 30, 2006, was updated in 2007 to the Sigma 18-50 / 2.8 Macro HSM version (with the 'HSM' prefix). The update has been implemented Only for Nikon cameras.

Differences between the old and new versions:

• different names. The newer version for Nikon cameras in its name on the lens body has an additional prefix 'HSM'.
• The new version has a built-in ultrasonic focusing motor. The first version for Nikon cameras did not have a focus motor at all
• the new version has two additional marks 1: 4.7 and 1: 4.2 on the scale of magnification
• the new version has an AF / M focus mode switch
• the new version has 10 microprocessor pins, and 5 the old
• new version available only for Nikon cameras, while the old version was produced for Sigma, Canon, Pentax and Sony
• the retractable frame of the body (trunk) in the new version consists of 2 parts, in the older version the trunk of the lens was made in one single section. Perhaps it makes sense to highlight the Sigma 18-50 / 2.8 Macro HSM not just as a modification of the Sigma 18-50 / 2.8 Macro, but as a standalone version?
• maybe there are other differences

Sigma has released updates many times for some lenses for Nikon cameras that incorporate an HSM motor. Sometimes updates were issued only for some other brand, for example, Canon. Because of this, sometimes very difficult to identify the lens model, especially, given the fact that the lenses were produced for different systems for different mounts and had some cosmetic improvements.

Trillions of versions and subversions of Sigma lenses drive me crazy.

Main technical characteristics of Sigma DC 18-50mm 1: 2.8 EX MACRO HSM:

Typically, aperture wagons try to stand out from the gray mass of regular whale lenses of class 18-55 / 3.5-5.6 with a wider viewing angle, using focal lengths of 16 mm (Tokina 16-50 / 2.8, Sony 16-50 / 2.8, Pentax 16-50 / 2.8) or 17 mm (Nikon 17-55 / 2.8, Canon 17-55 / 2.8, Tamron 17-50 / 2.8) In this case, only Sigma makes fast aperture zooms with the widest possible angle of 18 mm (Sigma 18-50 / 2.8 EX, Sigma 18-35 / 1.8, Sigma 18-50 / 2.8-4.5) But a special difference between 16, 17, 18 mm can not be noticed.

Assembly

Sigma 18-50 / 2.8 Macro was made in Japan. To the touch the lens is pleasant, strong, weighty. The retractable frame of the body ('trunk') consists of 2 sections, which are quite durable, without any backlash.

All parts of the body, except the one on which the focus switch is located, are covered with characteristic Sigma velvet.

The plastic part of the case on which the focus focus switch is located is identical to the model Sigma DC 17-70mm 1: 2.8-4.5 MACRO HSM. At the same time, to the left of the focus mode switch there is an additional place on the panel, which is screwed with two screws. This place is in similar models. Sigma DC 17-50mm 1: 2.8 Zoom EX OS HSM и Sigma DC 17-50mm 1: 2.8 Zoom EX OS HSM (possibly others) is used to set the stabilizer control switch. It turns out such a unified production. Also, the design and body size of all similar Sigma lenses is the same or very similar. It also makes it easier for Sigma to control production and reduce the cost of components.

The lens has metal bayonet mount. The zoom and focus rings are rubberized. Changing the focal length runs smoothly.

There is a bayonet mount mark and a mark on the case for quick installation of the hood. The lens uses a plastic hood, which is fixed in special grooves located near the front lens of the lens. The hood can be installed in the opposite direction for transportation. In this position, access to the focus ring at 18 mm focal length is lost. When you change the focal length, the lens hood moves with the front of the lens.

When changing the focal length, the rear lens moves in the middle of the lens body like a pump - it draws in and pushes out air. This behavior of the rear lens is called 'vacuum cleaner effect', which can increase the amount of dust that accumulates in the camera.

The number of aperture blades is 7 pieces, 2 additional blades (so that there are 9, as it should be for a top-class lens) they regretted. At the same time, they are slightly rounded and already form a heptagon on strongly covered diaphragms.

For Sigma 18-50 / 2.8 Macro, the direction of rotation of the zoom and focus rings does not match the direction of the original Nikon DX AF-S Nikkor 17-55mm 1: 2.8G ED IF SWM.

Considered to be a premium quality professional lens. Many professional lenses use classic 77 mm filters, 72 and 82 mm - less often. Sigma 18-50 / 2.8 Macro has 72 mm diameter filters. Subsequent update to Sigma DC 17-50mm 1: 2.8 Zoom EX OS HSM the diameter of the filters was made by 77 mm.

I want to note separately that despite the good assembly of the Sigma 18-50 / 2.8 Macro, the overall reliability of the lens is much inferior to the original metal monster Nikon 17-55 / 2.8G.

Sigma DC 18-50mm 1: 2.8 EX MACRO HSM

Lock 'LOCK ′

Frame (trunk) of the Sigma 18-50 / 2.8 Macro spontaneously changes its size under its own weight (perhaps this begins only with time). For example, when the camera is pointing up, the trunk of the lens spontaneously calls in (focal length decreases). On the lens case there is a focal length switch-lock 'LOCK' (the so-called 'lock'), which tightly locks focal length at a value of 18 mm.

To fix the trunk of the lens, you must first set the 18 mm focal length. Near the button there is a drawn arrow that indicates in which direction the switch should be moved to lock the lens.

The switch is located in a convenient place - under the thumb of the left hand, so the lens can be quickly and comfortably 'removed from the lock' before starting shooting.

The effect of spontaneous changes in focal length (trunk creep) in this lens is quite noticeable.

Sigma DC 18-50mm 1: 2.8 EX MACRO HSM

Focusing

To focus, the lens uses a special ultrasonic focusing motor 'HSM' (Hyper Sonic Motor). Most likely this is a compact rather than a ring HSM motor. Sigma 18-50 / 2.8 Macro will automatically focus on all Nikon DX cameras.

The emergence of HSM motors among the Sigma lens was partially facilitated by the output of cameras Nikon D40 in November 2006 and D40x in March 2007. Most often, for full compatibility with the new non-motorized model range, which spawned Nikon D40, in the cropped Sigma lenses with Nikon F mount they began to integrate the HSM motor.

When used on a camera Nikon D90 with unpretentious Multi-CAM 1000 focusing system the lens behaves well. I had no particular problems with focusing accuracy and tenacity. The lens clings well to the subjects being shot, rarely refocuses. The number of focusing misses is minimal.

Auto focus speed average, comfortable for the vast majority of photo tasks. Focus speed is slower than Nikon DX AF-S Nikkor 17-55mm 1: 2.8G ED IF SWM. Let me remind you that Nikon 17-55 / 2.8G so far it is the fastest original lens in the Nikon DX series (it uses a large and powerful ring SWM motor).

Focusing on the Sigma 18-50 / 2.8 Macro internal - when focusing, neither the front nor the rear lens rotates, and the lens itself does not change its size when focusing. Sorry, but during auto focus focus ring rotates and cannot be touched. In such Nikon lenses, the focus ring remains stationary during auto focus.

In manual focus mode, the focus ring rotates 60 degrees. Manual focus is quite inconvenient. When extreme positions are reached, the focus ring abuts and cannot be rotated further.

The minimum focusing distance is only 20 cm (the distance from the camera’s matrix to the subject). With such an MDF, the maximum magnification ratio is 1: 3. it good indicator for a similar lens. Thus, the lens allows you to shoot a good amateur 'close'. On the retractable frame of the case there are labels indicating the maximum magnification factor for certain focal lengths (see plate with TX).

Important: during shooting with a maximum magnification of 1: 3, the distance from the subject to the front lens is about 3 cm. During shooting, you can hook the subject of the shot with the trunk of the lens. Very often during macro photography, the shadow of the trunk of the lens gets into the frame.

Important: when using a lens hood, you will not be able to achieve a maximum magnification of 1: 3, since the lens hood will abut against the subject.

Similar behavior during macro shooting is observed with the lens. Sigma DC 17-70mm 1: 2.8-4.5 MACRO HSM.

The lens has focus mode switch 'AF / M'. For manual focus, the lens must be switched to 'M' mode, otherwise the focus motor may be damaged. Unfortunately, unlike many Nikon lenses of this type, the Sigma 18-50 / 2.8 Macro does not support continuous manual focus.

Focus Features:

• There is little noise from autofocus.
• There is a strong effect of 'Focus Breathing' (changing the viewing angle during focusing). During focusing towards MDF, the viewing angle increases. Partially small working distance during macro shooting is associated with this effect.
• When changing the focal length, focusing is a bit confused.
• Unknown compatibility with teleconverters.
• Sigma 18-50 / 2.8 Macro does not have hard stop (hard infinity mechanical stop) which allows you to accurately and quickly focus the lens at infinity under any external conditions.
• The lens has a focus distance scale with marks in meters and feet. The scale is plotted on the focus ring. The scale is very meager, on it there are marks for only 6 values ​​of the focusing distance (including 'infinity'). More advanced lenses usually use a scale in the form of a special window.
• Focus shift (shift-focus) was not noticed.
• Sigma 18-50 / 2.8 Macro has no focus problems in Live View (tested on Nikon D90 ), but focuses slowly.
• The lens transmits the focus distance to the subject in the camera (analog Nikon D, Nikon G).
• The direction of rotation of the focus ring does not match the original Nikon 17-55 / 2.8G.
• Sigma 18-50 / 2.8 Macro is a third-party lens. It may happen that it will not work correctly with some Nikon cameras. Details on this issue are considered by me. here.

Image quality

In general, Sigma 18-50 / 2.8 Macro, as for a lens of its class, is optically not bad.

Sharpness

• confident sharpness at open apertures in the center of the frame over the entire range of focal lengths
• no noticeable drop in sharpness during zoom
• poor sharpness at the edges of the frame at 18mm & f / 2.8
• very weak picture in the corners of the frame at 18mm & f / 2.8
• at the edges of the frame, sharpness becomes acceptable after f / 5.6
• in the corners of the frame, sharpness becomes acceptable after F / 8.0
• good / excellent resolution in the center of the frame on covered apertures (in the F / 4-F / 10 region) over the entire range of focal lengths

Distortion

• the overall level of distortion is at a level typical for such lenses
• pretty strong distortion only visible at 18 mm
• distortion practically absent and imperceptible in the range of 24-50 mm
• in the wide-angle range, the nature of the distortion barrel-shaped
• the nature of distortion is unified, easily corrected in the editor

Vignetting

• general level vignetting is at the level typical for such lenses
• noticeable vignetting is observed over the entire range of focal lengths and F / 2.8
• the strongest vignetting appears at 18mm & f / 2.8 when focusing on MDF
• vignetting amplified with focus towards MDF
• vignetting practically disappears at F / 4-F / 5.6
• vignetting easily fixable in the editor

Aberration

• on F / 2.8 there is a small amount of spherical aberrations that go away already with F / 3.5
• the strongest chromatic aberration visible at 18mm & f / 2.8 at the edges and corners of the image
• when closing to F / 4-F / 10 HA are slightly reduced
• general level HA is at the level typical for such lenses

Rest

• color rendering is neutral, possibly with a slight shift in warm colors
• pronounced effect of a 14-ray star on strongly covered diaphragms
• a small amount of glare in the backlight, a slight drop in contrast in the side light. Immunity is at the level typical for such lenses.

Sigma 18-50 / 2.8 Macro was developed at a time when the number of megapixels on the camera was no more than 12 (Nikon D2x: 12 MP, produced since 2004). I do not think that the Sigma 18-50 / 2.8 Macro would be the ideal solution for cameras with 24 or more megapixels. But, as practice has shown, even on such cameras, old lenses can behave themselves with dignity.

My experience

Repair masters say the Sigma 18-50 / 2.8 Macro is mechanically much better than a classmate Tamron Aspherical LD ​​XR DI II SP AF 17-50mm 1: 2.8 [IF] A16.

As a result, the Sigma 18-50 / 2.8 Macro (version HSM) is the best non-original solution of the aperture wagon with a constant F / 2.8 without a stabilizer for amateur Nikon DX cameras without a focus motor.

Sigma holds the record for the number of fast lens iterations, especially for Nikon cameras (there are about 5 of them). Ultimately, this affects the fact that each subsequent iteration can remove the flaws of the previous one and make the best possible lens. For example, Canon, Sony, Pentax and Tokina have only one such model (at the beginning of 2018).

I am pursuing the idea that a photographer should have one good fast all-rounder for a wide range of tasks. In the actual practice of a photographer, such a lens can often be very helpful, especially at certain stages of the development of the photographer. The station wagon is the basis with which you can 'survive' in almost any photo task. To this base, it is then worth adding other creative / artistic / special lenses of a narrower specialization.

Nevertheless, those who are looking for an inexpensive high-speed wagon, I recommend that you first look at the original lenses. After them, look at the versions with a stabilizer from third-party manufacturers, and there are not many of them. At the time of this writing, these are only Sigma DC 17-50mm 1: 2.8 Zoom EX OS HSM (highly recommend this lens) and Tamron Di II SP 17-50mm F / 2.8 VC B005.

Tamron AF 17-50mm f / 2.8 SP XR Di II LD Aspherical [IF] VC B005 and Sigma DC 18-50mm 1: 2.8 EX MACRO HSM

Results

The Sigma 18-50 / 2.8 Macro is a balanced all-rounder. The model is outdated, but still is a worthy candidate as a fast zoom for a wide range of photo tasks.

Advantages

1. low cost in the secondary market (especially compared to Nikon 17-55 / 2.8G)
2. convenient set of focal lengths
3. rear mount lens hood
4. metal mount, rubberized focus and zoom rings. Soul Warming Marking 'EX'
5. lock for fixing the lens in position 18 mm
6. special optical elements in the optical circuit (Sigma SLD, ELD, ASP)
7. good maximum magnification ratio for macro shooting, which is 1: 3
8. ultrasonic built-in focus motor
9. not slow focusing (comfortable for work)
10. focus type internal
11. lack of focus-shift during iris
12. constant maximum relative aperture of 1: 2.8 over the entire range of focal lengths
13. the presence of a lens profile in most popular RAW converters (certainly there is in ACR, Lightroom)
14. good optical performance (good sharpness on covered apertures in the center of the frame, normal sharpness on open apertures in the center of the frame, other parameters are within the normal range for this kind of lens)

Disadvantages

1. very small distance from the subject to the front lens during macro photography
2. in the vast majority of cases, it will be impossible to perform macro shooting at the maximum possible scale for the lens with the lens hood attached (lens hood rests on the subject)
3. the direction of rotation of the focus ring and zoom does not match the original similar lens Nikon 17-55 / 2.8G
4. large enough diameter for light filters (72 mm)
5. small stroke of the focus ring, insufficiently convenient manual focus
6. lack of dust and moisture protection (critical for a professional lens)
7. rotation of the focus ring during auto focus. Lack of continuous manual focus control
8. no depth of field scale and tags for working in the infrared spectrum. The focus distance scale is not made in the form of a window, but is simply applied to the focus ring
9. rear lens movement while changing the focal length, small effect of a vacuum cleaner / air pump
10. not even enough hole aperture on covered diaphragms
11. there may be incompatibility with some cameras and / or teleconverters (no exact data)
12. lack of data about the lens in modern cameras, which makes it difficult to automatically correct some types of distortion (distortion, vignetting etc.)
13. lack of updating to the version with the HSM focusing motor for cameras Canon, Sigma, Sony, Pentax, 4/3. The difficulty of identifying the version of the lens
14. palpable barrel-shaped distortion 18 mm focal length, tangible vignetting 18 mm focal length, poor resolution at 18 mm in the corners of the frame on open apertures, noticeable glare in backlight
