when i look at the price, $100-$180 for something equivalent to a Nikkor $400 same specs... i wonder...

I cannot find any information on the picture you can get with them online... besides the reviews on the page, and samples looks correct, why would i pay 3x the price for a Nikkor equivalent?

 

i'd like to understand please

 

MEKE 85mm F1.8 YONGNUO YN50mm F1.8N

They are third-party lenses. They use reverse-engineered firmware that can cause the AF to stop working if Nikon add new functionality to the communications protocol. 
 

At this price point, there is probably very little quality control applied. This means large sample variation as every item produced reaches the consumer.

 

What you pay for with a Nikkor is consistency because of tighter tolerances in production and a better QC protocol, often a more complex shape to the aperture blades giving a rounder opening, higher quality glass and coatings and a distribution network that stand behind their products.

 

The better, more established third-party manufacturers are at the same level as the camera  manufacturers these  days, but the same canĀ“t be said about many of the newcomers who use a low price to attract customers.

some users do mention incompatibilities, that is correct.

i will follow your advice and buy a new nikkor 35mm 1.8 !
