The Chinese are rapidly copying the lenses of famous brands. The Yongnuo 35mm f/2 and YN 50mm f/1.4 are the next lenses after the YN 50mm f/1.8 to come to the market from Yongnuo. Yongnuo is not limited to Canon-only lenses. At the time of this writing, lenses for Nikon can be found in the company's catalogs. At the same time, externally, the products are hybrids of the well-known and ever-produced lenses of the flagships of the photographic industry.
Yongnuo 35mm f / 2 review for Canon
The Yongnuo YN 50mm f / 1.8 review clearly showed us that the lens is almost identical to the Canon 50mm f / 1.8 II. Looking at the YN 35mm f / 2, we see a design that is painfully familiar to us. Indeed, why reinvent the wheel? In the age of 3D visualization technologies in design and estimate software systems, you don't have to think about the appearance, because they have already thought for us earlier.

Also, YN 35mm f / 2 scheme is a close-to-functionality copy of the 35 Canon EF 2mm f / 1990 lens layout. We can verify this by following the Canon Lens Museum website. Accordingly, the number of elements and groups must match. So it is - 7 elements in 5 groups. Refers to wide angle lenses. Reviews of wide-angle lenses on the portal:

Yongnuo 35mm f / 2 in action
However, on modern cameras, the lens does not represent something completely uncommon at work. Standard sores of a noisy micromotor, known from the Canon EF 50mm f / 1.8 II, slight inconveniences from the lack of an adequate distance scale, autofocus noise. At the same time, for all that, the image quality from the lens is adequate for the price.
Yongnuo 35mm f / 2 lacks an ultrasonic autofocus motor. The drive uses a conventional micromotor, which is rigidly connected to the focuser design. It is better not to touch the focusing ring in AF mode to avoid damaging the delicate drive gears. When searching for an object, you may hear a noticeable noise. However, its speed is something that cannot be complained about - it takes about 0,5-0,6 seconds to travel across the entire distance scale during focus adjustment. It would be difficult to name the autofocus mechanism as accurate, because the number of misses in various shooting conditions ranges from 10 to 30%. This is, of course, a good result, but modern lenses are often aimed at the best result.
The manual focus ring is only 8mm wide. The ring is rough, the range across the entire distance scale is only about 80 degrees. Thanks to the focusing gear drive and the lack of any smoothness of the ring movement, the precise adjustment of sharpness turns into a competition for endurance.
On the EOS 1300D, the sample from the review, it automatically focused quite accurately. I was pleased that the percentage of marriage on the ancient Canon EOS 300D crop did not go beyond the permissible limits, because in cameras without LiveView, work in focus mode using phase sensors has no alternatives, and autofocus adjustment is not available. Due to the backlash of the autofocus system mechanism, micro-sharpening is still available. Let's call it that.
