Budget Yongnuo 50mm f/1.8 AF for Nikon, cheapest fast prime for zero-risk bokeh experimentation.
The Yongnuo YN 50mm f/1.8 for Nikon F is a budget autofocus standard prime providing fast f/1.8 at the lowest possible price. Yongnuo reverse-engineered the nifty-fifty concept to produce an AF 50mm f/1.8 at a fraction of Nikon's own pricing.
The f/1.8 aperture delivers background blur and low-light capability at prices that make fast prime photography essentially risk-free. The autofocus communicates with Nikon F-mount bodies for basic AF and EXIF data, providing functional AF convenience.
Build quality is basic plastic construction at the absolute minimum pricing. The optical quality is functional for everyday use, though it cannot match genuine Nikkor alternatives in sharpness and rendering consistency.
The Yongnuo 50mm f/1.8 offers the cheapest possible AF fast prime for Nikon at negligible used cost. The f/1.8 speed provides the fast-prime experience at zero financial risk for photographers wanting to try bokeh and low-light shooting.
