In this review, I will call the Ynlens YN50mm F1.8S DA DSM lens for short YN 50 / 1.8S.
The YN 50 / 1.8S is the first lens from Ynlens (Yongnuo) for Sony mirrorless cameras with an APS-C sensor (i.e. with a cropped sensor) and a Sony E mount.
YN 50 / 1.8S - a classic fifty dollars. Internal auto focus, quiet and fast enough stepper focus motor. Everything works without problems. Optically good, with good sharpness over the entire field of the frame, without strong distortion or vignetting. Only chromatic aberration make themselves felt.
YN 50 / 1.8S - lightweight, compact, pleasant. It is strange that other manufacturers have not yet released an affordable similar lens for Sony E. Those fifty lenses that already exist are either manual (without autofocus) or have a significantly higher price tag.
The lens was officially announced April 10 2020 years.
YN 50 / 1.8S is first lens from Yongnuo for the cropped mirrorless Sony system with Sony E mount. It is not known from what lens it was copied and whether it was copied at all, maybe this is Yongnuo's own development. Why copied? Indirectly this is evidenced by the fact that nowhere on the lens, box or instruction does the inscription 'Yongnuo' shine, but only 'Ynlens'. Perhaps this is due to some kind of patent obligations, or maybe it's just such a small rebranding.
This is what the lens and the box in which it is delivered look like. In some pictures, it is shown along with the camera. Sony a3500.

In general, the YN 50 / 1.8S is an alternative to the original Sony 50 / 1.8 OSS. There are few croaked fifty dollars, while they are quite popular among amateur photographers, since cropped cameras can act as budget portrait and creative lenses.
The lens came to the review completely new, with the serial number '3000001'. The front and rear lenses were covered with protective films.
In a small box was a warranty card, instructions in Chinese and English, a certificate of quality control, a desiccant, bags, a lens hood and the lens itself with a front and rear cover. The covers are made of thick plastic. In the box, the lens is mounted with two foam locks. The box is tiny.
YN 50 / 1.8S has metal mount. Stated that microprocessor contacts gilded. The focus ring is wide, plastic. The lens case is made of plastic, but it feels good in the hands. The focus ring has a small transverse play, but does not cause much discomfort.
The weight of the YN 50 / 1.8S is only 146 grams. Light weight goes well with the lightweight Sony NEX / Alpha cameras.
Diaphragm consists of 7 petals, on the strongly covered diaphragms the aperture opening has the shape of a regular heptagon.
There is a bayonet mount mark and a mark on the case for quick installation of the hood. The lens uses a plastic lens hood LH-52T, which is fixed in special grooves located near the front lens of the lens. With the hood in the active position, the front cover is very difficult to install. The lens hood is long enough, optimized for the lens to be used on cropped cameras.
It's important: The hood, in fact, cannot be set to transport mode with the back side. Nevertheless, it can somehow be set into transport mode, but in this position it will not be possible to close the lens with the front protective cover.
I want to note that on the lens itself there is no inscription 'YONGNUO' inherent in all previous lenses from this company. Instead of 'YONGNUO' you can now see the inscription 'Ynlens'('YoNgnuo LENS? ','Wi-Lens? '). The same applies to the box in which the lens and instruction arrived. Mention that this is Yongnuo is only in the utility for updating the firmware.
For focusing, the YN 50 / 1.8S uses stepper focus motor DSM (Digital Stepping Motor). Auto Focus should work with all Sony cameras with an E / FE mount.
Focus speed average (closer to high), quite comfortable for work. On camera Sony a3500 I had no problems with focusing at all. After the lens has lost accurate focusing, refocusing is fast enough. The lens is also tested on the Sony α5100 and Sony α6000.
Auto focus silent. In some situations, a characteristic hum appears (as with many stepping focus motors). But still this hum is not very noticeable and rarely appears (it depends on the chosen focusing method and current conditions that affect focusing). While shooting a video using auto focus and a microphone built into the camera, the video may still have a small noise level from the built-in motor. On some cameras in the tracking AF mode during video recording, a small crack may appear from a very frequent change in the direction of focus.
Lens uses electronic focus ring. Focus ring plastic, not rubberized, wide, in manual focus mode rotates approximately two full turns. When extreme positions are reached, the ring does not abut, but continues to rotate. Manual focus is enough conveniently. The focus ring rotates very easily (with one finger). I did not observe delays when changing the direction of rotation. The focus ring during manual focusing makes a faint sound of two rubbing plastic parts. The electronic focus ring is more responsive to its speed of rotation than to a specific angle of rotation, which sometimes creates a tactile inconvenience.
UPDATE: After two weeks of active use in the field and about 5.000 shots, dust fell under the focus ring, after which a characteristic rubbing sound and a characteristic unpleasant tactile sensation appeared.
On the case no focus mode switch. The focus method is set through the camera menu. For manual focus, select the focus mode MF (manual focus) or DMF (direct manual focus) in the camera menu, after which the focus ring will respond to rotation after half-pressing the shutter button.
During auto focus focus ring remains stationaryMoreover, it can be freely rotated 360 degrees without any effect on focusing (if the normal AF 'Autofocus' mode is activated in the camera menu). During manual focusing, the focus distance bar appears on the display of some cameras.
The lens has internal focusing, the front and rear lenses remain stationary during focusing. It is possible to use various filters without any problems.
The minimum focusing distance is 45 cm, while you can get the maximum magnification for macro photography 1: 7.1, which is the usual value for fifty-fifty lenses.
The YN 50 / 1.8S has the 'Focus Breathing' effect (changing the viewing angle during focusing). During focusing towards the MDF, the viewing angle decreases.
There are no useful marks on the focusing distance, depth of field, or anything else on the lens.
Focus shift (shift-focus) was not noticed during operation and testing.
Firmware update (changed)
There is a USB port on the lens housing of the YN 50 / 1.8S with which you can update the lens software (firmware / firmware). This feature first appeared in Yongnuo 100mm 1: 2 и Yongnuo 40 / 2.8that were presented at the same time.
Unlike previous Yongnuo lenses, for which the program was downloaded separately and new firmware downloaded separately, for the YN 50 / 1.8S you need to use a utility that immediately carries the new firmware.
The functionality of the Yn50mm F1.8 DA DSM FM Updater utility (Update Tool 220.127.116.11), which is responsible for working with the YN 50 / 1.8S lens, is very meager. You can only see the current firmware version and update it to a new one. I found this utility for my YN 50 / 1.8S here. There is a utility version only for the latest Windows operating systems.
A widespread USB 2.0 MICRO-B port is used to connect to the lens (many mobile phones use just that). A USB cable is not included. To connect, I used a USB cable for my Android phone and updated the firmware without any problems. The procedure took less than 10 seconds.
A firmware update, most likely, allows you to improve the compatibility of the lens with new cameras, improve the auto focus, eliminates some other errors. Too bad that no way to roll back (restore) an older version of the firmware.
To upgrade the firmware (software) of the lens:
- Turn off the camera, detach the lens
- Launch Yn50mm F1.8 DA DSM FM Updater
- Attach the lens to the computer using a USB cable. If everything went well, the program will automatically detect the connected lens
- Click [Start] to start the update. Wait for the update to complete.
- Disconnect the cable. Done
The YN 50 / 1.8S easily handles an Exmor CMOS 20-megapixel APS-C sensor located in the heart of the camera Sony α3500 (ILCE-3500). Optically, this is a good lens, of obvious shortcomings - only chromatic aberration. A fairly flat field of sharpness over the entire frame deserves special attention. It’s quite difficult to notice the subsidence of sharpness even in the corners of the image.
- good sharpness on the open aperture both in the center of the frame and on the periphery of the image, F / 1.8 is fully operational
- good resolution in the center of the frame on covered apertures after F / 2.8
- there is no tangible drawdown of sharpness at the edges and corners of the image, even on an open aperture
- weak, pincushion distortion
- the nature of distortion is unified, easily corrected in the editor
- it is difficult to notice distortion in the pictures
- vignetting is most pronounced on F / 1.8 and focusing on infinity
- vignetting decreases with focus towards MDF
- vignetting almost disappears at f / 2.8
- vignetting is easily fixable in the editor
- the lens creates a sufficiently large number of chromatic aberrations, both longitudinal and transverse
- there is a noticeable freezing (color of contrasting zones of blur in green and purple)
- there is also the so-called blooming - strong and large red-violet halos on strongly contrasting elements
- chromatic aberration - the weakest side of the lens
- the effect of the rays of the star is not pronounced (14 rays)
- Blur disks are uneven on tightly covered diaphragms
- the lens works well in backlight, only in the most difficult conditions can you get glare that spoil the picture
- the lens does not use aspherical elements, but only ED elements, which helps to avoid concentric circles on blur discs
- discs of blur closer to the edges of the frame become clipped
There is currently no profile for this lens in popular RAW converters.

Sony a3500 I can’t shoot exclusively in RAW format, but only in RAW + JPEG or JPEG, because most of the pictures I took were made in JPEG. I have several photos in a little processing at 500px: 1, 2, 3, 4, 5, 6 and instagram: 1, 2, 3, 4.
The YN 50 / 1.8S is similar to its original Sony brothers - the lens is small, lightweight, without switches, with an electronic focus ring, etc.
I have no significant complaints about the image quality, as well as the overall functioning of the lens. The YN 50 / 1.8S has nothing more. This is a cheap and efficient lens.
First of all, the YN 50 / 1.8S is a serious competitor to the original Sony 50 / 1.8 OSS. For modern Sony cameras that have an integrated image stabilizer (Sony a6500, a6600), you can safely buy the YN 50 / 1.8S instead of the more expensive Sony 50 / 1.8 OSS.
Important: The YN 50 / 1.8S has many times fewer small and not very small problems than the fifty dollars from Yongnuo for Nikon and Canon SLR cameras. In this case, with the YN 50 / 1.8S everything is much better, and the YN 50 / 1.8S itself is not connected at all with the fifty dollars from Yongnuo for SLR cameras. Once again, as it is really important: this YN 50 / 1.8S and YN lenses for SLR cameras are radically different lenses.
The creative potential of such a fifty dollars is difficult to overestimate. It is suitable for a wide range of photo tasks. Photo enthusiasts often use it as a portrait lens. Many just want a fast fix, especially in addition to their full-time / 'whale' lens. Aperture F / 1.8 more than three steps wider f / 5.6 aperture, which is used on long-end 'dark' whale lenses. In numerical terms, this means that YN 50 / 1.8S is approximately 10 times brighterthan, for example, whale Sony 18-55mm f / 3.5-5.6 OSS or Sony 16-50mm f / 3.5-5.6 PZ OSSwhich use a maximum relative aperture of only 50: 1 over a 5.6 mm focal length. The calculation of the difference in the relative aperture (count the aperture) is performed elementarily: (5.6 * 5.6) / (1.8 * 1.8) = 9.679, which is rounded to the value '10'.

The price of the YN 50 / 1.8S is around $ 100-120, which is a very attractive offer. You can see prices for YN 50 / 1.8S on Aliexpress. at this link.
YN 50 / 1.8S - a good fifty dollars for mirrorless Sony E APS-C. Good value for money. The YN 50 / 1.8S has virtually no competitors.
10 main advantages:
- low cost (about $ 100)
- very light weight
- compact sizes
- metal bayonet mount included
- stepping focus motor fast enough
- internal focusing, fixed focus ring during auto focus
- electronic focus ring, convenient enough manual focus
- USB port for firmware upgrade
- one low dispersion element in the optical circuit (for example, Sony 50 / 1.8 OSS no special elements)
- good optical performance. Moderate level of basic optical distortion (vignetting, distortion, drop of sharpness to the edges and corners of the image, etc.)
10 main disadvantages:
- the hood is extremely inconveniently set to transport mode (maybe it can’t be installed like this at all)
- the aperture blades are poorly rounded; on heavily covered apertures the aperture has the shape of a heptagon
- tiny lateral play of the focus ring, the focus ring is plastic, not rubberized, can catch dust over time and rotate not so smoothly
- no built-in image stabilizer (similar Sony 50 / 1.8 OSS he is)
- there are no additional tags (depth of field, focusing distance, etc.)
- the minimum focusing distance is greater than that of a similar one Sony 50 / 1.8 OSS (important for subject and pseudo macro photography)
- software options for working with the lens via the USB port are very limited
- lack of lens data in modern cameras and RAW converters, which prevents some types of optical distortion from being automatically corrected
- it is not known where and how this lens should undergo warranty service. This is not Yongnuo, but Ynlens. Perhaps the company has problems with patent obligations
- some characteristic optical imperfections, such as perceptible chromatic aberration
