The question “What aperture is best for landscape photography?” is often asked in various online forums. While there isn’t one “correct” aperture, certain scenes benefit from using a specific one. For standard landscape photography (excluding night photography, macro photography and other niches), the optimal aperture for front-to-back sharpness lies within f/7.1 to f/13.

This is a big week for new top-tier gear at DxOMark. First, they crowned the Canon 1D X Mark II the best Canon sensor they've ever tested, and now the affordable Sigma 30mm f/1.4 DC DN Contemporary has been named DxO's top-ranking Sony E-Mount prime.
