Release New : Yongnuo YN 50mm F1.8 Features And Performance Review

The Yongnuo 50mm f/1.8 was the funniest announcement from 2014. A EF 50mm f/1.8 II rip-off, with same design and specs, its 15 minutes of fame were quickly over when Canon announced the new 50mm f/1.8 STM, with silent AF and updated optical formula. But the chinese have a card up their sleeve: at just US$62, half the Canon price, it has no peers for such a low cost on the SLR market. Known for low cost radio flashes, Yongnuo made its name among budget photographers, who don’t really understand the detours made for such a low cost.

Yongnuo 50mm F1.8 Features

Weighing only 120g, this lens is very light and portable, being 10g less heavy than the lens it owes its style to. Just like with the Canon edition, the lens gun barrel is designed almost entirely from light and portable black nasty, as is the bayonet. It all seems a bit weak and probably won’t deal with much misuse. The light-weight and lightweight makes for a great mixture with the Canon EOS 5D Mark III body used for examining.

Yongnuo 50mm F1.8 Images Quality


As far as sharpness cares, there is no distinction from the Canon 50 mm f/1.8 STM that we a short time ago analyzed. At complete aperture, the sharpness is far from maximum. You get a wonderful image, which can make an original feelings for images and low-light photos. After avoiding down two prevents, the maximum sharpness is achieved, and the Yongnuo (just like the Canon, by the way) gives nothing up to much more costly contacts with the same central duration.

As can be seen in the exercise taken above, a shiny mild in the qualifications generates a magnificently circular bokeh at complete aperture, with a little, shaded increased advantage. Thanks to a bigger variety of curved lamellae, the bokeh is clearly better than that of the first Canon 50 mm f/1.8 edition, which is sometimes still provided for selling at an affordable cost. The bokeh is better than that of most zoom capability contacts for APS-C, which are much less shiny and sometimes also have problems with a unsettled onion-ring framework.

With shiny contacts (< f/2.8), longitudinal chromatic aberration or “color bokeh” can be noticeable. At complete aperture with the Yongnuo 50 mm f/1.8, you sometimes see violet sides at distinct comparison changes that lie right before the focus and natural sides at distinct comparison changes (as proven here) that lie behind the focus. This might look impressive, but this trend is usually much less clearly noticeable, and it’s really easy to eliminate by avoiding down one quit. On this factor, too, the Yongnuo gives nothing up to the Canon 50 mm f/1.8 STM that we analyzed formerly.

Yongnuo 50mm F1.8 Performance

At highest possible aperture, sharpness in the center of the structure is already very excellent, although quality towards the sides of the structure is rather inadequate. Avoiding down enhances efficiency across the structure, although the distinction is more impressive in the center than towards the sides. Optimum efficiency in the center is obtained at f/4, where quality is excellent. Sharpness towards the sides needs a lengthy while to capture up, only attaining excellent stages by f/8 and peaking with very excellent sharpness between f/11 and f/16.

The red line symbolizes numbers from the center of image structure at the various apertures and saving money is from the sides. Calculating them out gives the red calculated line. The range on the left side is an indicator of actual image. The higher the line, the better the lens efficiency. For this evaluation, the lens was examined on a Canon EOS Mark III using Imatest. Chromatic aberrations are well managed, with fringing hanging around the 0.5 pixel dimensions towards the sides of the structure between highest possible aperture and f/4. This level is low enough to cause few problems, even in very large print out dimensions, or with severe plants from the sides of the structure.

Chromatic aberration is the lens’ lack of concentration on the indicator or movie all colors of noticeable mild at the same point. Serious chromatic aberration gives a recognizable fringing or a mobile effect around distinct sides within picture. It can be treated in application. Apochromatic contacts have special lens components (aspheric, extra-low distribution etc) to reduce the problem, hence they usually cost more. For this evaluation, the lens was examined on a Canon EOS 5D Mark III using Imatest. Falloff of lighting towards the sides is quite noticeable. At f/1.8 the sides of picture area are 2.54 prevents deeper than picture center and avoiding down to f/5.6 results in creatively consistent lighting.

Barrel distortions is common for a leading lens with a fast highest possible aperture. Imatest recognized 1.4% gun barrel distortions, which may become recognizable in pictures with directly lines similar to the sides of the structure, but should cause few issues most of the time. The distortions design is consistent across the structure, so it should be relatively simple correct in picture modifying application afterwards. No bonnet is provided with this lens. Even so, the front factor is recessed and is reasonably well shady as a outcome, so a bonnet may not be needed. Capturing into powerful mild resources, such as the sun, may outcome in a recognizable loss of comparison under certain conditions. Strong mild resources outside the structure may also cause surface.
