The ‘Sweet-Spot’ of a lens – by BH Insights

The sweet-spot of a lens can be defined as the F-stop where the lens performs its best thus delivering the best image quality. In other words, shooting at this F-stop will give you the “sharpest” images.

In a nutshell, according to BH Insights, “if your goal is to squeeze the maximum levels of image sharpness out of your lens you can achieve this by simply stopping your lens aperture down 2.5 to 3-stops from the lens’s maximum aperture. As an example, if the maximum aperture of your lens is f/2.8, you’ll want to shoot with your lens aperture set between f/5.6 and f/8. For a lens that has a maximum aperture of f/3.5, the sweet spot of your lens resides somewhere between f/8 and f/11.”

However, sharpness is not the same as objects being in focus in your images. To get the explanation on maximum sharpness and maximum focus, click here to read the whole article.
