Most lenses give optimal sharpness only when stopped down by 1 stop. For example A 100-400mm or an 80-400mm lens set at 400mm might give you sharper results at f/8 than at their widest aperture setting of f/5.6. At the widest aperture, these variable aperture zoom lenses yield softer images.

What aperture gives the sharpest image?
The sharpest aperture is when the overall image is at its sharpest. The sharpest aperture of your lens, known as the sweet spot, is located two to three f/stops from the widest aperture. Therefore, the sharpest aperture on my 16-35mm f/4 is between f/8 and f/11.
What makes a lens sharp?
Generally, this means that you want the subject to be in focus with clear lines, crisp details, and no (unintended) blurring. It’s a combination of accurate focus, a static camera, and the properties of the lens you’re using.
What is aperture of a camera?
Aperture refers to the opening of a lens’s diaphragm through which light passes. It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16.

Method for Testing Autofocus
- Place the card in a well-lit area, somewhere your camera will find it easy to focus on the card.
- Now, place your camera the correct distance from the test card, 50 times the focal distance of the lens.
- Open the aperture on your lens up to its widest.
- Now, manually focus the lens to infinity.

What is a soft lens in photography?
What is a soft focus lens? A soft focus lens deliberately uses spherical aberration in order to blur the image. Soft focus shots are not the same thing as out-of-focus shots and cannot be achieved merely by defocusing your lens. This effect is more about the diffusion of light.
Do lenses matter?
– the lens will offer far more control than the camera body. This is because aperture, focal length, and sharpness are all dictated by the lens, so by using the right lens and the right lens settings, you can achieve beautiful background bokeh, stunningly sharp subjects, perfect compositions, and more.

What is sweet spot of lens?
The sweet spot of a lens is simply the aperture value at which the lens is at its sharpest. For instance, most lenses are slightly soft at wide apertures like f/3.5. These lenses become sharper by stopping down to an aperture like f/8.
