The simple 50mm prime lens is a wonderful artistic tool on any camera. Here, open wide on a cloudy day at f/1.4 it renders a shallow depth of focus and the dreamy, creamy blur known as ‘boceh’. Boceh rhymes with mocha, Use the word and other photographers nod and smile. Some of them might even know what you are talking about. Those are the photographers you should spend some time with.
Every photographer NEEDS a 50mm lens. F/1.4 if you are daring, and the inexpensive and just as good F/1.8 if you want to keep the price down to around $120. The Nikon D version (used here) performs as well as their more expensive and less capable G version. Your mileage may vary.
