Today we will con­sid­er a lens (fifty dol­lars) for Sony mir­ror­less cam­eras from the man­u­fac­tur­er YONGNUO.

By the way, this is the first and so far the only prod­uct for cam­eras with an APS‑C sen­sor and Sony E mount.

Package:

Equipment:

Instruc­tions in Eng­lish and Chi­nese, detailed and under­stand­able.

The weight of the lens is 164 grams.

Although the lens does not feel expen­sive, it does not cause any com­plaints about the qual­i­ty. The body (like the lens hood and both cov­ers) is made of plas­tic, the build qual­i­ty is good. The lens hood secure­ly attach­es to the lens with a soft click.

A ribbed man­u­al focus ring is installed in the mid­dle, it rotates smooth­ly and pleas­ant­ly, there is no rota­tion lim­iter (you can see the aut­o­fo­cus oper­a­tion in the video review start­ing from 44 sec­onds). Switch­ing between man­u­al and auto focus is car­ried out direct­ly in the cam­era.

The lens has a Micro-USB port for con­nect­ing to a PC and updat­ing the firmware. The firmware can be down­loaded here.

The diaphragm con­sists of sev­en petals (you can see how it works in the video review, start­ing at 1:06).

Lens in action

All tests were car­ried out on a Sony A6300 cam­era.

A step­per focus motor is installed inside the lens, which pro­vides a good, fair­ly fast focus­ing speed both when shoot­ing pho­tos and videos (you can see it in the video review, start­ing at 1:18). The focus qual­i­ty is also good, even when shoot­ing a fast-mov­ing sub­ject in con­tin­u­ous shoot­ing, almost all frames are in focus.

It is worth not­ing that aut­o­fo­cus is very qui­et, only if you lis­ten close­ly you can hear slight motor sounds (espe­cial­ly if the aut­o­fo­cus track­ing mode is on and the pic­ture is con­stant­ly chang­ing).

As for the qual­i­ty of the pic­ture that this lens pro­duces, it is decent, the pho­tos are sharp and con­trast­ing, and in any area of ​​​​the pho­to and at any aper­ture.

Aber­ra­tions are clear­ly vis­i­ble at an open aper­ture, and there is also a vignette (at 1.8), espe­cial­ly at a large focal length (when shoot­ing at short focus­ing dis­tances, the vignette is not so notice­able). Already at aper­ture val­ue of 4.0, there are sig­nif­i­cant­ly few­er aber­ra­tions.

Sam­ple pho­tos tak­en at F1.8 (left) and 4.0 (right):

Dis­tor­tion is prac­ti­cal­ly absent, in any case it is imper­cep­ti­ble.

By the way, dis­tor­tion and vignette are easy to remove in Adobe Cam­era RAW (there is a cor­rec­tion pro­file for this lens), and aber­ra­tions can also be sig­nif­i­cant­ly reduced. How to do this can be seen in the video review, start­ing at 3:01.

Photo examples:

I com­pared this lens to a Sony 16–50mm 3.5–5.6 at 50mm. To my sur­prise, the reviewed lens is sig­nif­i­cant­ly bet­ter in terms of sharp­ness. In addi­tion, the Sony lens has strong vignette and a 50mm larg­er field of view.

Video review:

Sum­ming up, we can safe­ly say that Youngn­uo has turned out to be an excel­lent lens that I strong­ly rec­om­mend for pur­chase.
+ aper­ture 1.8;
+ excel­lent sharp­ness at any aper­ture;
+ fast and qui­et aut­o­fo­cus;
+ sup­port by the man­u­fac­tur­er;
+ low cost;

— notice­able aber­ra­tions at the widest aper­ture.
