Nikon D3400 and YONGNUO 50mm f/1.8 Review.

I have full support – autofocus with Yongnuo 50mm f/1.8 on my Nikon D3400 camera.

Yongnuo 50mm f/1.8 is just a little less sharp than my Nikon 50mm 1.8G.

Yongnuo 50mm f/1.8 has 30-40% slower autofocus than my Nikon 50mm 1.8G.

Yongnuo 50mm f/1.8 is always 0,3-0,7 overexposed (brighter) than the Nikon 50mm 1.8G with my Nikon D3400 camera especially on a sunny day, to get the same exposure as the Nikon 50mm 1.8G lens I need to underexpose my pictures be 0,3-0,7.

The Yongnuo 50mm f/1.8 lens does not use any special optical elements in its optical design.

VS

Nikon 50mm 1.8G has one Aspherical lens element to eliminate the problem of coma and other types of lens aberration – when used at the widest aperture.

Sun Flare Test.

Yongnuo 50mm f/1.8 lens is similar to the Nikon 50mm 1.8 AF-D lens when used at the widest aperture on a sunny day.

(When stopped down the Nikon lens is sharper)
