The Build quality.
The outside look is just the same as the Nikon 50mm 1.8G
after a little bit of use, it feels like the build quality is okay.
The YN 50mm lens does not use special optical elements in its optical design.
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, it works very well in my opinion.
Nikon 50mm 1.8D has Super Integrated Coating (SIC) for providing high-contrast image even with maximum aperture, in my opinion, doesn’t work so well.
When I’m using the YN 50mm F1.8 on my Nikon camera it feels like this lens has 30-40% slower Autofocus than my 50mm Nikon lenses.
Flare and ghosting.
This lens will flare when shooting in front of a big light source like the sun, and I can get ghosting when shooting at night time in front of a very powerful light.
Aberrations and distortion.
Not much, similar to 50mm Nikon lenses, many Nikon lenses suffer from this.
This image looks okay but when zooming 100% into the photo it is not sharp and that is basically how this lens is.
The image quality is okay, but sometimes the pictures can look flat and overexposed when used in bright daylight even on f/8.i have needed to underexpose by -0,7 to get the same exposure as Nikon 50mm 1.8G.
This lens is very similar to the nifty fifty from Nikon maybe just a hair less sharp.
When this lens is used on f/22 it will reduce the sharpness of the image a lot.
When I compare images from YONGNUO YN50mm F1.8 with images from the Nikon 50mm lenses side by side then this lens is not true 50mm it’s more like 46mm to 48mm.
This lens doesn’t have any special sharpness on any given aperture.
Very similar to the Nikon 50mm lenses.
I don’t care so much about lenses having vignetting as long as they are sharp and have contrast in the center then I’m happy, this lens does not have so much sharpness or contrast in the center to have an interesting characteristic.
This is a low contrast lens.
This lens does not have any special contrast on any given aperture, like some lenses that I have can be very soft wide open and then stopped down a little bit and they become very sharp and contrast, but this lens does not have that character.
low light handling.
This lens is okay to use in low light shooting handheld, I can get ghosting when shooting at night time in front of a very powerful light, but wide open this lens is not sharp it’s better to stop the lens down a little bit to get a sharp picture, f/2.2 or f/2.5 is okay.
Would I buy this lens, again?
Would I buy this lens again, not likely, I need a 50mm lens that I can use for professional use and I don’t recommend this lens for that, this is a amateurs lens in my opinion.
And now the big question, can I recommend anyone who uses Nikon DSLR to buy this lens?
Yes, but only for amateurs and photographers that think they are not going to use 50mm lens much but still want to have one in the camera bag, this lens has too slow auto-focus for professional use in my opinion.
The price difference.
What I liked the most.
The Build quality vs price is really good.
What I Didn’t like.
Slow autofocus and low sharpness.
