In this review, I will call the Sigma 10-20mm 1: 3.5 DC HSM EX lens abbreviated Sigma 10-20 / 3.5. Please also note that this lens is available for different cameras with different mounts. In the review, I have an option for the Nikon F mount for Nikon DX SLR cameras. At the same time, this lens is for Sigma SA, Canon EFS, Sony A / Minolta A and Pentax K.

In short

The Sigma 10-20 / 3.5 is a popular and highly successful ultra wide-angle lens for cropped DSLR cameras of various systems. It is a good balanced solution and belongs to the professional Sigma EX series lenses. At one time it became a replacement for the same popular, but older and 'dark' Sigma 10-20mm 1: 4-5.6 EX DC HSM.

First of all, Sigma 10-20 / 3.5 attracts 10 mm of focal length, constant maximum apertureUltrasonic focusing motor and good assembly. But optically, there are minor problems, and 82 mm filters are not to everyone’s liking (or can’t afford).

In general, it is a replacement for the professional original Nikon 12-24 / 4G and for amateur original Nikon 10-24 / 3.5-4.5G и Nikon 10-20 / 4.5-5.6G VR.

F / 3.5 is only a third step lighter than F / 4 in many other similar lenses, for example, Tokina 12-24 / 4. At the same time, F / 3.5 is 2/3 steps darker than that of F / 2.8 on models Tokina 11-16 / 2.8, Tokina 11-20 / 2.8, PENTAX 11-18 / 2.8, FUJINON 8-16 / 2.8. The lightest of these can be considered Tokina 14-20 / 2.0. At the same time, it is important to realize that very often super-wide angles are used on very closed diaphragms, which is why the maximum relative aperture is not always as important as for standard or telephoto lenses.

Assembly

Sigma 10-20 / 3.5 was made in Japan. To the touch the lens is pleasant and weighty. The lens has a considerable weight, which is a little more 500 grams. On small cameras such as Nikon D3200, the weight balance is slightly biased towards the lens but it does not cause any discomfort in operation. Sigma 10-20 / 3.5 uses large / huge filters xnumx diameter mm. But the installation of filters with a thick rim does not affect the vignetting.

There is a bayonet mount mark on the body and a mark for quick installation of the hood. The lens uses a plastic hood that is fixed in special grooves located near the front lens of the lens. On the hood there are arrows labeled 'IN' and 'OUT', in the direction of which the hood should be installed and removed. The hood can be installed in upside down for transportation. 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 barrel. The effect of the air pump is not expressed at all.

The retractable body frame ('trunk') consists of 1 section. The trunk is durable, without any backlash. When the focal length is changed, the trunk moves in a wave-like manner. The maximum extended trunk is observed at 10 mm focal length, minimum - at 15 mm. The movement of the trunk does not exceed 0.5 cm and is almost invisible, we can assume that the lens has almost an internal zoom. True, I still managed to place my index finger between the lens sections and press it a little when changing the focal length from 10 to 20 mm.

In Sigma 10-20 / 3.5, the direction of rotation of the focus ring do not match with direction from the original Nikon 12-24 / 4Gand the direction of rotation of the zoom ring is the same.

The lens has metal bayonet mount. Most of the internal power elements of the lens are also made of metal. The zoom and focus rings are rubberized. Changing the focal length runs smoothly. The zoom ring rotates 45 degrees. The assembly of the Sigma 10-20 / 3.5 is exactly the same as most EX lenses of that time.

The assembly of Sigma lenses is so unified that the plate on which the focus mode switch is located has a dummy for another switch, usually it is a stabilizer mode switch, for example, like Sigma 17-70 / 2.8-4 OS. The plate is fastened with two screws and its design is typical for almost all Sigma lenses of that time.

Number of petals aperture - 7 pieces. At the same time, they are slightly rounded and form a regular heptagon on strongly covered diaphragms. Aperture blades form a completely flat aperture only 20 mm focal length. During a change in focal length in the direction of 10 mm, it is visually noticeable how the aperture blades slightly close and form a hole with small notches already.

Important: At first, this lens was produced in a case with a velvet sigma coating, but later replaced with a classic glossy one, as in this review.

Focusing

To focus, the lens uses a special ultrasonic focusing motor 'HSM' (Hyper Sonic Motor) ring type... This is an analogue of Nikon SWM / Canon USM / Pentax SDM / Sony DDSSM motors. In this case, the Sigma 10-20 / 3.5 is similar to an 'AF-S' type lens in Nikon terms.

The lens will automatically focus on all Nikon DSLR cameraseven on amateur series models Nikon DXthat do not have a built-in focus motor: D40, D40x, D60, D3000, D3100, D3200, D3300, D3400, D3500, D5000, D5100, D5200, D5300, D5500, D5600as well as mirrorless cameras Nikon Z with adapter FTZ / FTZ II.

During automatic focusing, the motor performs its work quite quietly, but nevertheless, noise from the focusing motor is clearly audible on videos recorded using the microphone built into the camera. In Live View, with frequent and quick changes in focus direction to accurately fine-tune the focus, the lens creates a distinctive strong crack.

Auto Focus Speed high. It is believed that the focus speed is not important for the super-wide, and the presence of automatic focusing as such. But still fast and tenacious autofocus greatly simplifies the life of the photographer.

When used on a camera Nikon D3200 with unpretentious Multi-CAM 1000 focusing system the lens behaves very well. With precision and clinging focus, I had no particular problems at all. The same goes for use on Nikon D40. On camera Nikon D3200 I checked the presence of the back and focus front at different focusing distances (infinity and MDF as well). Pictures taken using the Live View mode (which does not suffer from back / front focus) were used as a measure. Focusing accuracy using phase sensors completely coincided with the Live View mode. In Live View, the lens also works well.

The focus ring is rubberized and in manual focus mode rotates approximately 135 degrees. When extreme positions are reached, the ring does not abut, but continues to rotate freely. The focus ring rotates quite tight. Manual focus is quite convenient. Direction of rotation of the focus ring does not match with original Nikon 12-24 / 4G. In automatic focus mode, the focus ring does not rotate and you can hold the lens behind it.

Lens has internal focus, the front and rear lenses remain stationary during focusing. When changing the focal length, the front lens also does not rotate. It is possible to use various filters without any problems.

The lens has a window with a focus distance scale in meters and feet. The number of values ​​on the scale is small, the scale itself is not very useful. There are values ​​only for 0.24, 0.27, 0.3, 0.4, 0.6, 1 meter and an infinity mark. Infrared scales and labels for working in the infrared spectrum are not.

The minimum focusing distance is 24 cm and the maximum magnification ratio is 1: 6.6.

There is a lens housing focus mode switch 'AF | M '(auto focus / manual focus). Lens supports continuous manual focus control (Full-Time Manual Focus). This function only resembles native functions. Nikon 'M / A' or Nikon 'A / M'. The mode is more similar to the analog from Canon - Canon FTM, or to the 'A' mode for some Nikon DX lenses, for which it is described in detail here. In short, it is convenient to perform manual focus in the auto focus mode 'AF' (switch position on the lens) is possible only if the camera uses the focus mode 'AF S'and only after successful automatic focusing. In focus mode 'AF-C'' camera can counteract manual focus control. Sigma 10-20 / 3.5 does not turn off auto focus when you start to rotate the focus ring manually, due to which different incidents can occur. Original Nikon lenses with function 'M / A' immediately turn off the auto focus completely and only listen to the manual control of the focus ring. But if you use the focus method with the button AF ON (or the button programmed for this function, or the remote control), you may not feel the lack of a full mode Nikon 'M / A' or Nikon 'A / M'. This is a pretty subtle little thing that can be quickly understood only in practice.

Focus Features:

1. Important: the quality of the Sigma 10-20 / 3.5 focus in Live View greatly depends on the camera used, as well as on the system used for the lens
2. Sigma 10-20 / 3.5 has mild 'Focus Breathing' effect (changing the viewing angle during focusing).
3. Focus Shift (focus shift, changing focus distance due to iris)
4. Sigma 10-20 / 3.5 does not have a hard stop (hard infinity mechanical stop) which allows you to accurately and quickly focus the lens at infinity under any external temperature conditions. For accurate aiming at infinity, you cannot just bring the focus ring to its extreme position. The focus ring can have a large overrun for infinity.
5. The lens transmits the distance to the subject in the camera and is Nikon D-lens equivalent.
6. Important: Sigma 10-20 / 3.5 is a third-party lens. It may happen that it will not work correctly with some cameras. Details on this issue are considered by me. here
7. Teleconverter compatibility unknown
8. Unknown compatibility with Nikon FTZ adapter for Nikon Z mirrorless cameras and with Nikon FT1 adapter for mirrorless cameras Nikon 1

Image quality

The lens was designed at a time when the camera with the highest pixel density was Canon EOS 50D 15 MP (summer 2008), but even nowadays Sigma 10-20 / 3.5 easily digests cameras with APS-C 24 MP sensors.

Sigma 10-20 / 3.5 is optically balanced. With an over-wide angle, one must take into account that almost all lenses in the corners and edges of the image do not give the best image quality, and therefore at this point you should always make a discount. After the very first frames on Sigma 10-20 / 3.5 you can’t get enough of how good this lens is in the center of the frame.

Sharpness

• the lens was surprising, good resolution in the center of the frame over the entire focal length range. When closing the aperture in the center of the frame, the sharpness is just excellent
• A serious problem is the angles at 10 mm of the focal length, which do not return to normal even with strong aperture. Only with an increase in focal length can an acceptable sharpness be achieved in the corners of the covered diaphragms. But getting really good sharpness in the corners is impossible.
• Update: it is believed that the old version Sigma 10-20mm 1: 4-5.6 EX DC HSM in the corners of the frame 10 mm was better than the version from the review
• as the focal length increases, the edges of the image improve in terms of sharpness

Distortion

• overall distortion is slightly better than many other similar lenses
• rather strong distortion is visible only by 10 mm
• distortion is practically absent in the region of 15 mm focal length
• in the range of 10-15 mm the nature of the distortion is barrel-shaped, in the range of 15-20 pincushion
• the nature of distortion is unified, easily corrected in the editor

Vignetting

• the overall level of vignetting is at a level typical for such lenses
• vignetting is most pronounced at 10 mm at F / 3.5
• with increasing focal length, vignetting at an open aperture decreases
• vignetting almost disappears at f / 5.6
• vignetting is practically independent of the focusing distance
• vignetting is easily fixable in the editor

Aberration

• the strongest chromatic aberration visible at 10 mm and F / 3.5 at the edges and corners of the image
• chromatic aberration decrease with increasing focal length
• at average focal lengths, aperture closing does not help reduce chromatic aberrationbut rather even enhances them
• general level HA is at the level typical for such lenses

Other

• lens tolerates side and backlight very wellcatching the lens by surprise with a bright light source is quite difficult
• diaphragm blades form a spinning heptagon on almost any hidden value
• with closed apertures, you can get a pronounced effect of a 14-ray star

The data on this lens is in most popular RAW converters (it is definitely in ACR, Lightroom), which makes it very easy to correct distortion and vignetting with one click.

But in modern cameras, this lens is not 'sewn up' and it will be impossible to obtain automatic correction of some optical defects of the lens. For example, on camera Nikon D3200 with installed Sigma 10-20 / 3.5 function 'Aut. distortion control 'inactive.

My experience

Sigma 10-20 / 3.5 is a good lens, with it you can be sure of quality and reliability. Personally, I really liked it, even more than the pretty options Tokina 11-16 / 2.8, Tokina 11-20 / 2.8.

There is nothing more complicated than selecting a width / oversize. Typically, the selection of such lenses is approached more carefully than with any other lenses.

From Tokina there are faster options, from Tamron there are options with a higher zoom ratio and with a stabilizer. The original options are sometimes too expensive. And every photographer has their own preferences. In one case, the task is in the maximum possible viewing angle, in the other case, in the maximum possible aperture ratio. Sometimes super-wide is generally taken as a wide-wagon (for example, for this it is well suited Tokina 12-28 / 4).

If you don’t walk in circles, then Sigma 10-20 / 3.5 is really one of the most optimal over-widths for crop. Truth,

• under Canon EFS there is an original bestseller with stepper motor and image stabilizer Canon 10-18 / 4.5-5.6 EF-S IS STM, with a very good price / quality / opportunity ratio. When choosing a lens for Canon EFS, I would look at him
• Nikon DX also has an original bestseller with a stepper motor and image stabilizer Nikon 10-20 / 4.5-5.6G VR AF-P, with a very good price / quality / opportunity ratio. When choosing a similar lens for Nikon DX, I would look at him
• for other systems for which Sigma 10-20 / 3.5 is produced (Sigma SA, Sony A / Minolta A and Pentax K) there is no simple and balanced choice, you need to choose in torment between many original and non-original options from Sigma, Tamron, Tokina, Samyang

Results

The Sigma 10-20 / 3.5 is a very successful lens. Perhaps it has minor flaws, but in general it is a good, balanced solution for anyone looking for an ultra-wide lens for cropped SLR cameras.

10 main advantages

1. constant maximum relative aperture over the entire range of focal lengths
2. built-in HSM focusing motor (critical for owners of low-end Nikon DX cameras)
3. fast focusing, internal type focusing
4. almost internal zoom (the lens practically does not change its size when changing the focal length)
5. Sigma EX Series Professional Lens
6. good build quality: metal bayonet mount, rubberized focus and zoom rings, bayonet type hood with the ability to install the reverse side
7. many special optical elements in the optical scheme (3 ASP, 2 SLD, 1 ELD)
8. the ability to use 10 mm of focal length (for example, Tokina, Pentax, Sony A do not have similar lenses with 10 mm)
9. the presence of a lens profile in most popular RAW converters (certainly there is in ACR, Lightroom)
10. good and sometimes excellent optical performance (moderate distortion и vignetting, very good sharpness on both open and covered apertures in the center of the frame, good glare)

10 main disadvantages

1. tight focus ring, the direction of rotation of the focus ring does not coincide with the original similar lenses, for example, Nikon 10-24 / 3.5-4.5G
2. low zoom ratio (e.g. Tamron 10-24 / 3.5-4.5 zoom ratio is higher)
3. a crackling sound with frequent and fast changes in the direction of auto focus (observed, for example, in tracking mode in Live View)
4. lack of an integrated image stabilizer (for example, it has Nikon 10-20 / 4.5-5.6G VR)
5. continuous manual focus control does not work as convenient as the original mode Nikon 'M / A' у Nikon 12-24 / 4G
6. not the highest aperture (e.g. Tokina 11-20 / 2.8 aperture higher)
7. 82 mm large filter diameter (e.g. Canon 11-22 / 4-5.6 diameter only 55 mm)
8. all weather protection is absent, not even rubber lens mount seal (e.g. lens PENTAX 11-18 / 2.8 AW has a very high level of protection)
9. there may be incompatibility with some cameras and / or teleconverters (no exact data), lack of data about the lens in modern cameras, which makes it difficult to automatically correct some types of distortion (distortion, vignetting etc.)
10. palpable barrel distortion of 10 mm focal length, very poor resolution of 10 mm in the corners of the frame on open and covered apertures
