In short

The Sony E 18-50 is a universal stock lens for Sony NEX / Sony Alpha mirrorless cameras with an APS-C sensor. This lens came exclusively with the Sony A3500 camera, and therefore is little known and not common. Such lenses are called 'kit' lenses and are considered the simplest with the smallest set of features. However, kit lenses have a bunch of positives, of which the most important is the low cost when purchasing a camera and lens kit.

The Sony E 18-50 is lightweight, with a very quiet and fast focus motor. Threefold zoom makes the Sony E 18-50 a very convenient solution for beginners and amateurs.

Of the obvious shortcomings is the lack of a built-in stabilizer, aperture at the wide end (F / 4 versus F / 3.5 for other similar lenses) and the absence of a focus ring.

There is simply no information on this lens in official sources. Most likely, Sony is embarrassed by the fact that its track record has the Sony E 18-50.

History

11 May 2010 the lens was introduced Sony E 3.5-5.6 / 18-55 OSS (Optical Steady Shot, E-mount, SEL1855), which is one of the first three lenses for Sony mirrorless cropped cameras with an APS-C sensor. Initially, there was only a version Sony E 18-55 in a silver case. Version Sony E 18-55 в black case appeared only with the release of the camera NEX-7 24 August 2011 year.

12 September 2012 a similar lens was introduced Sony E 3.5-5.6 / PZ 16-50 OSS (Optical Steady Shot, Power Zoom, E-mount, SELP1650) with electronic zoom and much more compact size when folded. 16-50mm f / 3.5-5.6 PZ OSS cannot be considered a substitute for Sony E 18-55It is rather his complement.

March 24 2014 Sony E 4-5.6 / 18-50 (E-mount, SEL1850) (shown in this review) that came with the camera a3500... This lens was discontinued in 2016. Sony E 18-50 is not a logical continuation Sony E 18-55 or Sony E 16-50, since it lacks a built-in stabilizer and focus ring and uses a much simpler optical design.

The F / 4 aperture is only a third step darker than the F / 3.5 at other similar lenses. True, the decrease in aperture affected not only 18 mm of the focal length, but also the rest of the range of focal lengths between 18 and 50 mm. Already at 35 mm of the focal length, the maximum aperture rests on the value of F / 5.6, that is, there is no smooth and proportional drop in aperture from 18 to 50 mm of the focal length.

Assembly

Sony E 18-50 was made in Thailand. The touch is pleasant and reliable.

The lens has plastic bayonet mount. The zoom ring is very wide, rubberized, pleasant to handle, rotates 90 degrees.

Important: Sony E 18-50 has no focus ring (For the first time I see this among similar lenses).

The retractable frame ('trunk') consists of 1 section. The trunk is plastic, but durable, without any backlash and without spontaneous movement. During a change in focal length, the trunk moves in waves. The maximum extended trunk is observed at 18 mm focal length, the minimum - at 35 mm. The movement of the trunk does not exceed 0.5 cm. We can even assume that the lens has almost internal zoom. But the rear lens during the change in focal length moves strictly linearly - it deepens with increasing focal length into the lens body. The trunk of the Sony E 18-50 does not spontaneously change its size under its own weight, and there are no problems with the trunk over time.

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 zoom ring becomes uncomfortable. While changing the focal length, the lens hood moves with the trunk of the lens.

The rear lens has a rectangular lens hood that cuts off excess light and prevents stray light.

The diameter of the front filter is 55 cm, a lot of other Sony E lenses have a smaller diameter of the filter by 49 mm, for example, 16mm f / 2.8 or 55-210mm f / 4.5-6.3 OSS.

The diaphragm consists of 7 rounded petals that form a round hole.

The Sony E 18-50 is one of two original Sony E zoom lenses for the APS-C without built-in image stabilizer... The second is professional Sony E 16-55mm f / 2.8 G.

Focusing

The lens uses a built-in stepper focus motor.

Auto focus speed medium closer to high. The focusing speed will depend slightly on the camera used. Sony a3500 cameras, for which this lens was developed, used automatic focusing by contrast, which is sometimes slower than the hybrid focusing methods of subsequent generations of Sony Alpha. Auto focus is very quiet.

While working with the Sony a3500 camera, the focus accuracy was at a high level. With good lighting, there are practically no problems with accuracy, tenacity, and refocusing.

It's important: Sony E 18-50 no focus ring. Manual focusing can be done only through the camera, but as I did not dance with a tambourine near the Sony a3500 menu, I still could not focus manually using the camera controls. Perhaps with other cameras this inconvenience is solved more simply.

During focusing, the front lens remains stationary, as the lens uses internal focus. Thus, it is possible to use any filters without problems, for example polarizing or gradient.

The minimum focusing distance is 40 cm, while you can get the maximum magnification for macro photography is approximately 1: 6

Other focusing features:

  • Focusing speed is practically independent of the selected focal length.
  • After the lens has lost accurate focusing, refocusing is fast enough.
  • The lens does not have a depth of field scale, focusing distance, and tags for working in the infrared spectrum.
  • Focus shift (shift-focus) was not noticed during operation and testing. At the same time, due to the features of the Sony mirrorless cameras, this ailment with these cameras is not terrible at all.
  • The focusing speed depends heavily on the illumination, the selected focusing mode in the camera menu, and the focusing logic of each individual camera.
  • During manual focusing, the focus distance bar appears on the display of some cameras.
  • When changing the focal length, focusing is a bit confused.
  • Sony E 18-50 has a small 'Focus Breathing' effect (changes in viewing angle during focusing).

Image quality

The Sony E 18-50 performs well with the 20MP APS-C Exmor CMOS sensor at the heart of the camera. Sony α3500 (ILCE-3500). Optically, this lens does not have critical bad sides, but in general it is confident middle whale. I think that with modern 24 MP and 32 MP cropped sensors, the Sony E 18-50 lens will show itself no worse.

Sharpness

  • sufficient resolution in the center of the frame over the entire range of focal lengths on an open aperture. Significant improvement in sharpness when closing aperture
  • angles of 18-24 mm focal length are quite weak and require serious aperture
  • as the focal length increases, the edges of the image improve in terms of sharpness on the open aperture

Distortion

  • there is barrel distortion in the range of 18-35 mm
  • small pincushion distortion with a range of 35-50 mm
  • the nature of distortion is unified, easily corrected in the editor

Vignetting

  • vignetting is at a level typical for such lenses
  • vignetting is most pronounced at 18 mm at F / 4
  • with increasing focal length, vignetting at an open aperture decreases
  • vignetting almost disappears at f / 5.6
  • vignetting is easily fixable in the editor

Aberration

  • the strongest chromatic aberration visible at 18 mm and F / 4 at the edges and corners of the image
  • chromatic aberration decrease slightly with increasing focal length
  • the number of chromatic aberrations is at the level of other similar objects
  • Sony's native EDIT 1.4 utility very well removes chromatic aberration from the original RAW files automatically ('Lens Correction' -> 'Chromatic Aberration Correction' function)

Other

  • lens well tolerates side and back light, the amount of glare is small
  • aperture blades form a regular heptagon on virtually any hidden aperture value
  • on closed diaphragms you can get a pronounced effect of a 14-ray star (see examples of photos, this effect is shown there)

Most popular RAW converters, such as ACR and Lightroom, lack data for this lens. Worst of all, vignetting and distortion cannot be corrected in one click with the original Sony EDIT 1.4 utility, which features Lens Correction / Distortion Compensation unavailable for RAW '.ARW' files from this lens.

True, the menu Sony a3500 you can enable automatic correction: 'Corr. ob .: Shading 'and' Corr. about: Chrome. aberr. '. But here is the function 'Corr. Rev .: Distortion 'is disabled and cannot be enabled with this lens. At the same time, I will remind you once again that the Sony E 18-50 was created specifically for Sony a3500.

My experience

Sony E 18-50 is very strange. A ghost lens, without clear official data, only for a rare Sony a3500 camera, which itself was produced and sold only in some countries and regions. It goes without saying that the Sony E 18-50 will work on other Sony NEX / Alpha cameras without any problems.

Sony E 18-50 is not even on the great list 'ULTIMATE GUIDE TO E-MOUNT LENSES FOR SONY APS-C MIRRORLESS CAMERAS'.

The Sony E 18-50 does not have a focusing ring. None, not even electronic! I have never seen anything like this before, even the simplest whales and any other interchangeable lenses for SLR or mirrorless cameras with an APS-C sensor have a focusing ring.

At the same time, the Sony E 18-50 is a well-balanced lens and has its good points. I really liked the almost internal zoom, which is a huge rarity for such lenses, as well as the pleasant autofocus performance.

Quite a decent whale lens.

Results

Sony E 18-50 is a simple and straightforward kit lens. Very cheap on the secondary market. Most likely it is cheapest original lens for Sony E APS-C. Optically, it does not have serious problems, but it does not particularly shine. It is very strange that there is so little information about this baby.

10 main advantages:

  1. compact sizes
  2. very low weight (only 158 grams)
  3. almost internal zoom (trunk movement is minimal and inconspicuous)
  4. focus type internal
  5. focus is very quiet and fast enough
  6. stepper (or similar) focus motor (important for movie shooting)
  7. included hood
  8. very wide and comfortable zoom ring
  9. aftermarket lens availability (cheapest original lens for Sony E APS-C)
  10. quite sharp images, especially on covered apertures. No major optical issues

10 main disadvantages:

  1. missing focus ring (what? seriously!)
  2. reduced aperture at the wide end (F / 4 vs F / 3.5 in similar Sony 16-50 и Sony 18-55)
  3. reduced focal length at the long end (50 mm versus 55 mm for similar Sony 18-55)
  4. there is no built-in image stabilizer (such Sony 16-50 и Sony 18-55)
  5. plastic mount (y Sony 16-50 it is metallic, while Sony 16-50 still easier)
  6. rear lens movement during focal length changes (may suck in air with dust)
  7. 55 mm filter diameter (many other Sony E lenses have 49 mm diameter)
  8. no normal official lens data (ghost lens)
  9. under this lens, there are no profiles for popular RAW converters that can quickly eliminate some optical flaws, native utilities and even original Sony cameras are not able to automatically correct distortion
  10. optical imperfections inherent in such lenses. First of all, high distortion, tangible chromatic aberration and low resolution at the edges and corners of the frame in the wide angle range

Comments: 21, on the topic: Review of Sony E 4-5.6 / 18-50 (E-mount, SEL1850)

  • Koba

    Is it just me, or is the lens really sharp? And even a nice looking picture gives ...

    • Arkady Shapoval

      someone will definitely joke that the words “whale” and “sharp” are not compatible. But yes, this kid, and even with a simple 6/6 scheme, is quite a good lens. I myself was extremely surprised.

  • BB

    Sony stands out, and writes FR / aperture vice versa))

    • Arkady Shapoval

      in fact, many do

      • Onotole

        Yes, but from an arithmetic point of view it’s not so right)

  • Dezmond2

    I had an A3500 with such a whale, and before it there were a couple of Canon ... so the whale from Canon seems to be complete trash compared to this Sony. Autofocus is practically inaudible, except that in complete silence you begin to hear it clearly, but on the street you cannot hear it at all ... which cannot be said about Canon, even the USM version.

    • Roman

      It depends on what. DC III is terrible. IS STM is a pretty decent whale, especially the latter, which is smaller and darker at the wide end. The USM kit seems to exist, but I didn’t come across it with us.

      Again, even the 18-55 / DC III is quite suitable for filming and training.

  • Koba

    For the sake of interest, I tried to look at the price and it turned out that no one was selling it in all of China. A very rare thing.

    • Arkady Shapoval

      By the way, I wrote a letter to Brian Smith, who manages'ULTIMATE GUIDE TO E-MOUNT LENSES FOR SONY APS-C MIRRORLESS CAMERAS'suggesting to add the Sony E 4-5.6 / 18-50 (E-mount, SEL1850) to the list, as it is Sony's native lens for the APS-C E, and was told that the camera lens was sold exclusively in' Australia, Mexico , Russia, Eastern Europe, the Middle East, and Africa '. No lens has been added. Discrimination.

  • Oleg

    I have one that I don’t really like.

  • Sergei

    At the price of the secondary, this subject practically does not differ from the used Sony 18-55 (which is well known and has been tested in various reviews several times). True, on sale this subject slips much less often.
    But it is more dimensional, without a stub, and six lenses in the optical scheme have always been very embarrassing.
    Plus the lack of a focus ring.
    This is the first review of this subject for me, where a definite positive clearly sounds.
    Conclusion: if you got it, then do not rush to put on a dusty shelf or throw it away. Maybe it’s useful for something.
    PS
    When I almost got the Sony 3500 carcass almost for nothing, I got the well-deserved 18-55 for it in the kit.

  • Jankowsky

    The marketing and technological concept of this "plug" is simply ingenious - there is NO focus ring - but the creative engineer from Aunt Sonya, in any case, would not hurt to tear off his hand with the meat ... And after all, judging by the photo, the lens is not bad and even sharp, comfortable and generally fit. The drawing seemed nicer and more textured than that of the 16-50 OSS. How reliable is it - that's another question

  • Alexey

    most likely you can do external manual focus control. I don’t know why :)

  • Victor

    Wow. A3500 with this lens is my first “real” camera ... To be honest, the lens went to Avito very quickly, because the picture from it was soapy, and shooting with such aperture and without a stabilizer was only possible on a bright sunny day. SEL55210, which also, in general, does not shine by the standards of the DSLR world, seemed a real revelation after it.

    I would venture to suggest that SEL1850 is subject to a strong variation in quality from copy to copy.

    • Ilya

      I did not see anything in Arkady's photographs that significantly differed from the photographs taken by my copy. According to my, perhaps too high, standards, this is not sharpness. After such a lens, even an unkilled Helios 44-2 will seem like a revelation (if you do not shoot in backlight).

      • Arkady Shapoval

        I shot a lot at 18-55 oss and played around with 18-50 oss for a long time (from the review). Even for a million I would not distinguish from each other, while more often 18-50 is more contrasting

  • Fyodor

    I don’t understand the suffering on the stabilizer. But what about filming without stubs before and everything turned out? Or the most important whims of marketers to satisfy?

    • US6IBD

      Well, then no one tried to shoot 1/5 or 1/10. And the stabilizer allows it. For "dark" and long-focus lenses, a good "stray".

    • Onotole

      And so they filmed. On a more or less fine day - without a tripod. In all other cases, either with a tripod or with a flash, or did not shoot at all. It is now possible to wind up IBIS, OSS, ISO12800-25600 and get some pictures for 1/2 second, at night in the entrance with a blown out light bulb. And then it was impossible, that's all.

  • Ilya

    “But here is the function of 'Corr. Rev .: Distortion 'is disabled and cannot be enabled with this lens. I would like to remind you that the Sony E 18-50 was created specifically for the Sony a3500. ”
    Arkady, you misunderstood the menu: on the contrary, the distortion correction for this lens cannot be turned off, it is always on! If you look closely at the monitor after taking a shot at the wide end, you can see how the aligned image “hatches” from the eerie barrel.

    For me personally, the lens does not seem to be sharp in the center. In my opinion, it is more or less equally unsharp across the entire field. Is it an instance? The SEL 18-55 is really sharp in the center and lathers noticeably in the corners.

    Manual focusing for this lens is not provided in principle, the tambourine will not help. The only thing is that you can first focus on the subject in automatic mode, then switch to manual focus and pre-focus with the movement of the camera (the method is suitable only for shooting close objects. It is very unpleasant that the magnifier does not work when autofocus is on - check the accuracy of the subject in focus on the creepy display or in the no less creepy EVI A3500 without increasing it is simply impossible, it remains only to rely entirely on far from the best CAF.

    I don’t know about the others, but my specimen (bought together with a carcass with a mileage of about 5 thousand, appearance for 5) has an unpleasant glitch: during continuous shooting with refocusing, only the first frame is correctly exposed, on all subsequent apertures the aperture does not open on given value, they are underexposed. Therefore, in practice, only continuous shooting with focusing on the first frame is possible, then the aperture remains in the set position throughout the entire series.

    I am somewhat surprised that this lens was injured to many. Probably just the whales of other systems (I have never used them) are even worse. At Soniclab, this lens was called the "carcass plug", with which I almost agree. The only application where he showed himself relatively well for me is shooting with macro attachments.

    • Arkady Shapoval

      Apparently, nevertheless, you did not have the best copy
