I own Nikon d3100 with Kit lens. I am planning to purchase my first Prime Lens. But I can not decide between Af-s 35mm 1.8 and Af-s 50mm 1.8. I was wondering weather they differ in sharpness and quality or it is just about focal lens. If not, Which can creat better bokeh and what are advantages of each and disadvantages. Generally speaking which one is more recommended?
