Just thought any interested Canon folks may like to see this Yongnuo 50/1.8 mm for Canon lens comparison.
While you could probably get a second hand Canon 50/1.8 for about the price of the Yongnuo lens .. well the Y lens is new at that price.
(nothing beats a new lens I reckon).
Comparison images look pretty good for the Y lens .. and bokeh from the lens looks quite good too!
If there were a Nikon version, I'd reckon I'd have one just for the sake of having a cheap lens(not that I need another 50mm capable lens )
Just thought some folks may be interested.
