In the review, I will refer to the Sigma 30mm 1: 1.4 DC A lens as Sigma 30 / 1.4 Art. This review shows the Nikon DX version of the lens for Nikon F mount cameras, but I will make footnotes in the description for other systems as well. The Sigma 30 / 1.4 Art is also available for Canon EF / EFS, Pentax K-mount, Sigma SA-mount and Sony / Konica-Minolta A-mount (this is what the lens looks like with these mounts). Very important: Sigma 30 / 1.4 Art should not be confused with two similar lenses Sigma 30mm 1: 1.4 EX DC HSM (older version) and Sigma 30mm 1: 1.4 DC DN | C (Contemporary) (version only for mirrorless cropped cameras). Sigma 30mm 1: 1.4 DC A (Art) In shortThe Sigma 30 / 1.4 Art is a great fast lens for SLR cameras with an APS-C sensor. In fact, this is a universal fix for a very wide range of tasks. If a quick squeeze on the lens, then:
Sigma 30mm 1: 1.4 DC A (Art) Nikon F mount HistorySigma 30 / 1.4 Art became an update for the famous and popular predecessor Sigma 30 / 1.4 EX DC HSM. As a result, there are three similar Sigma lenses:
Separately, it is worth highlighting an alternative for the Sigma 30 / 1.4 Art - a zoom lens with a very high aperture Sigma 18-35 / 1.8 DC Art and full-frame-like lens Sigma 35 / 1.4 Art. And Sigma has another less light 'thirty' - Sigma 30mm 1: 2.8 DN | A (Art) for mirrorless cameras Micro 4/3 and Sony E. Sigma 30mm 1: 1.4 DC A (Art) Nikon F mount Main technical characteristics of Sigma 30mm 1: 1.4 DC A:Review Instance Name The lens barrel bears the following inscriptions 'SIGMA 30mm 1: 1.4 DC A ø62 MADE IN JAPAN 013', the review shows the lens serial number 53497246 Basic properties
There are also options for:
The lens is deprived of the aperture control ring, control occurs through the camera menu (analog ) MDF 0.3 m, maximum magnification ratio 1: 6.8 The weight November 435, XNUMX According to my measurements:
Lens hood Plastic, bayonet type, LH686-01 Manufacturer country MADE IN JAPAN (Lens made in Japan) Production period Since January 29, 2013, in February 2016, it has been supplemented with a similar lens, but already for mirrorless crop cameras in the face Sigma 30mm 1: 1.4 DC DN | C (Contemporary) Price View on E-katalog Sigma Launches Very Interesting Art Lenses 20/1.4, 24/1.4 и 28/1.4, it would be really cool to see their “reduced” counterparts for cropped cameras. For example, 24 / 1.4 in some cases would be much better suited as a standard lens for cameras with an APS-C sensor (it would give EGF 36 mm). For example, the Fujifilm APS-C mirrorless system has an interesting FUJINON ASPHERICAL LENS SUPER EBC XF 23mm 1: 1.4 R (gives EGF 35 mm). The Micro 4/3 system has a wonderful OLYMPUS M.ZUKIO DIGITAL 17mm 1: 1.2 PRO (EGF 34 mm). For Sony E, Canon M, Fuji X on the approach of Viltrox 23 / 1.4 and Tokina 23 / 1.4. Sigma 30mm 1: 1.4 DC A (Art) Nikon F mount AssemblyThe lens came to the review completely new, in an original small box, which contains a warranty card, an addition to the warranty card, a leaflet about the new concept of Sigma A / C / S lenses, a huge manual in different languages, a wardrobe trunk, packing bags, a hood and the lens itself with front and back cover. The wardrobe trunk has a belt clip, the main valve with a zipper and two sliders. Assembly is carried out only in Japan. To the touch the lens is pleasant and weighty, its weight is about 430 grams and almost half a kilo with hood and covers. The Sigma 30 / 1.4 Art uses small 62mm filters. For the sizes of Sigma cthbb ART lenses, I have prepared small video on your Youtube channel. In itself, this is not a very large lens, in appearance it is similar in size to Nikon 50 / 1.8G. Even on Nikon DX series small amateur cameras, the lens has a good weight balance. The serial number of the lens is indicated on its front side, to the right of the focus distance scale (when viewed from the bayonet side). It is written in small print, I suspect that over time this inscription will be erased. Typically, serial numbers are placed on the front side only with the most expensive and TOP lenses in order to quickly identify a particular instance in large companies and services. The focus ring is rubberized, wide enough, the base of the focus ring is metal. The lens body is made of composite material - TSC — Thermally Sbackgammon Composite (Thermally Stable Composite), which is less sensitive to temperature changes than conventional polycarbonate. Such a composite avoids deformation of the case with a large change in ambient temperature. This material is used by Sigma to manufacture its' A | ART ',' C | Contemporary 'and' S | Sport '. In addition, the lens has metal bayonet mount. Plastic thread for filters. The body has a bayonet mount mark and a mark for quick attachment of the hood. The lens uses a sturdy plastic hood Sigma LH686-01, which is fixed in special slots located near the front lens of the lens. The hood is large enough to have arrows labeled 'IN / OUT' to rotate in the desired direction. The hood can be installed in the opposite direction for transportation. In this position, access to the focus ring and focus mode switch is lost. The hood has a grooved ring that makes it easier to manipulate. The diaphragm consists of 9 blades; at F / 1.4-F / 4 values, very smooth circles of blur discs are obtained, but with further closure, 9 facets become more clearly visible. Overall build quality is at a high level. It's important: Sigma 30 / 1.4 Art is not a protected lens, it does not even have rubber lens mount seal. Sigma 30 / 1.4 Art supports working with usb dock, and also theoretically supports replacing one mount with another (done exclusively at Sigma service centers). If someone suddenly once made such a replacement, please describe your experience in the comments. Sigma 30mm 1: 1.4 DC A (Art) FocusingTo 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 30 / 1.4 Art is similar in Nikon terms to an 'AF-S' type lens. The lens will automatically focus on all Nikon DSLR cameraseven on amateur series models that 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 with adapter FTZ / FTZ II. During auto focus, the motor does its work very quietly. The lens auto focus speed is average, closer to high. Focusing speed is enough for comfortable work in most photo tasks. But still I expected a much higher focus speed, maybe the speed depends a little on the camera used and the firmware of the lens itself. On the network you can find reviews about the lightning-fast speed of autofocus, but the instance that I had in the review did not show such a reaction, and the lens run time from infinity to MDF and vice versa is several times faster than modern whale lenses with a stepper motor, such as Nikon 18-55 / 3.5-5.6 AF-P or Canon 18-55 / 3.5-5.6 STM. With box lens from review had an explicit front focus (focused in front of the subject). Front-focus was always at all focusing distances, and the closer the subject was, the stronger the focus error. On cameras with the ability to fine tune the focus, you can easily fix this ailment (in my case, on Nikon D700 I indicated an amendment +6). But it's better to fine-tune the focus with dock stations and utilities SIGMA Optimization Pro (there is support for the Russian language). In large cities, you can rent this station. The Pentax version is especially famous for the poor autofocus performance, performing many misses. On my Nikon autofocus cameras, I didn’t have any particular problems, but still I want to note that focal tenacity worse than original similar lenses. There are also rumors that the newer the camera, the worse Sigma 30 / 1.4 Art works on it. The focus ring is rubberized and in manual focus mode rotates approximately 90 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 not very convenient. Direction of rotation of the focus ring does not match with original Nikon 35 / 1.8 DX. In automatic focus mode, the focus ring does not rotate and you can hold the lens behind it. It's important: the range of distances is very 'knocked down' from one meter to infinity from which manual focusing is very inconvenient and difficult. Focus manually through JVI at distances further than 1 meter it is so difficult that even with a careful approach to F / 1.4, I got no more than 10% of the pictures with the correct focus. Lens has internal focus, during focusing, the front lens remains stationary, only the rear group of lenses moves, the so-called rear focus system (рисунок) Optical design and focusing are designed in such a way as to avoid loss of image quality at different focusing distances. It is possible to use various filters without any problems. I easily used Sigma 30 / 1.4 Art with a polarizing filter HOYA 62mm PL-CIR. 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 0.3, 0.4, 0.6, 1, 2 meters and an infinity mark. Infrared scales and labels for working in the infrared spectrum are not. The minimum focusing distance is 30 cm, and the maximum magnification ratio is 1: 6.8 (significantly worse than Sony DT 35 / 1.8where it equals 1: 4). There is a lens housing focus mode switch 'AF | MF Focus' (auto focus / manual focus). Lens supports continuous manual focus control (Full-Time Manual Focus). This function only resembles native functions. 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'or' AF-A 'and only after successful automatic focusing. In focus mode 'AF-C'' camera can counteract manual focus control. Sigma 30 / 1.4 Art 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 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 or Nikon 'A / M'. This is a pretty subtle little thing that can be quickly understood only in practice. Focus Features:
Lens hood Sigma 30mm 1: 1.4 DC A (Art) Image qualityWith the quality of Sigma 30 / 1.4 Art, almost everything is in perfect order. This is a sharp, contrast lens with little distortion and very little vignetting. The only serious drawback is significant freezing. Sharpness

Rest
For Sigma 30 / 1.4 Art, there is a lens profile in popular RAW converters, which simplifies the automatic correction of some distortions. Sigma 30 / 1.4 Art was released in early 2013, when 24 MP APS-C cameras already existed on sale Nikon D3200, D5200, Sony SLT-A77, SLT-A65, and therefore, most likely, the lens was immediately designed to work on sensors with a high pixel density. Wardrobe trunk Sigma 30mm 1: 1.4 DC A (Art). Appearance taken from bhphotovideo Full frame capabilities and APS-HThe lens is designed to work with cameras with APS-C sensors (crop factor around 1.5). But the lens feels good on и Sigma sd quattro h with Kf = 1.3X, creating minimal vignetting. Serious vignetting is already present on full-frame cameras. Vignetting increases while focusing on infinity. The smallest vignette is visible when focusing on the MDF with the F / 16 aperture fully closed. At infinity and at medium focusing distances with F / 1.4 and shooting in RAW, completely fix vignetting through the editor fails. Vignetting on Nikon D700 (FX, ISO mode 1, RAW-> JPEG native converter, vignette control disabled) and its gain is clearly shown in the selection: Archive with source RAW on Nikon D700 in FX mode (full frame) here. Some Nikon full-frame cameras have additional crop modes, such as 5: 4, 1.2X, 1.3X, which can help get rid of some of the dark corners. Of course, at the full frame, the sharpness to the edges and corners of the image drastically subsides. Examples on the Nikon D40No panic, below are examples of other cameras! On camera Nikon D40, which has only 6 megapixels (low pixel density), the lens is very sharp in the center of the frame already at F / 1.4, but at F / 2.0 a miracle happens and you can get the so-called “ringing” sharpness all over the frame. Examples of pictures on Nikon D40 I included it simply to show how the lens works on the CCD sensor, its character and pattern in certain situations. I love contrast sets of "lens + camera", in this case Nikon D40 + Sigma 30 / 1.4 Art shows a very nice and unusual bunch.

My experienceFor some reason, no other manufacturer of photographic equipment does not produce such lenses for their digital cropped SLR cameras with an APS-C sensor. Of the original lenses for popular cropped mirror systems, it is generally very difficult to find fast full-time fixed lenses. It seems that manufacturers have conspired and ignore the cropped mirror segment. The same lenses that exist significantly lag behind the Sigma 30 / 1.4 Art. Of those that come to mind, only one or two of these can be distinguished: Nikon 35 / 1.8 DX, PENTAX-DA 35 / 2.4 и Sony DT 35 / 1.8, other similar ones have either been developed for a full frame, or for mirrorless crop, or is it again Sigma in the face of an older model Sigma 30mm 1: 1.4 EX DC HSM. 30 mm on a crop is generally more convenient than the more common focal length of 35 mm. By the way, Sigma 30 / 1.4 Art on cameras Sigma SD9, SD10, SD14, SD15 with Kf = 1.74 it practically turns into a classic fifty kopeck piece (EGF 52 mm). Sigma 30 / 1.4 Art is a very attractive solution for owners of cropped cameras. But as a single lens, especially for everyday use, still Sigma 18-35 / 1.8 Art will be much more practical. Given the migration of many professional photographers to full frame, you should consider whether Sigma 30 / 1.4 Art is needed. Perhaps it makes sense to take on the full-frame growth Sigma 35 / 1.4 Art, which in the general case is in no way optically and functionally inferior to the cropped version. Sigma 30 / 1.4 Art is exactly that one lens, that one prime, with which you can go on cropping for a long time, since there is practically nothing more worthy with about the same price tag. During the preparation of this review, I tried to talk with all the photographers I could find and who worked with this lens. Almost everyone praises its optical performance and complains about the autofocus. Therefore, I believe that all the same original Nikon 35 / 1.8 DX is a more balanced and optimal solution. But for other systems, the choice is not so obvious. And a little bit of the classic flame: 30 / 1.4 in terms of EFR and equivalent aperture in the understanding of the depth of field corresponds to the full-frame lens 45 / 2.1, and therefore a regular fifty-fifty lens at full frame in some situations can give a more interesting picture, especially if it's more or less modern 50 / 1.8, for example, Nikon 50 / 1.8G.
