Photography tips Aperture and Lens Sharpness

Technique Photography - Photographer beginners are often surprised to see that the new expensive lenses they bought was not sharp at all aperture settings. When my friend asked the more experienced photographers in the professional sense, they will inform you that there is a difference in terms of image sharpness at any aperture that we used. Each lens has an optimal aperture where he will work with the optimal, in other words we call it the razor-sharp results.
 

Aperture that produces the sharpest or commonly called the "Sweet Spot" varies from lens to lens, but as a rule of thumb, most lenses have a "sweet spot" when they lowered between 2 or 3 stops from maximum aperture. For example, the lens has a maximum aperture of f/2.8 has a "sweet spot" in the f/8.0 aperture.

So how do we know the "Sweet Spot" of the lens?
Actually there is a simple and fun way to test these lenses. Buddy just need a tripod and newspapers. To perform this test or tests you have to do is to attach a piece of paper on the wall, and make sure got enough light. Second, put your camera on a tripod, take a look at the spirit level on the tripod to make sure that the camera and the walls are really parallel. Take a series of photos with the most exposure to the narrow width of the lower one stop each snapshot / frame (do not forget to change the shutter speed in order to get the right exposure and consistent.) Keep shooting until you have gained the exposure (photo) for each aperture .

Buddy then be able to download or transfer images to your Personal Computer (PC), and open all the photos and compare! Compare the images using metadata or often called EXIF, to see how the aperture setting used. Buddies do not be surprised when he saw the results of the comparison, the result is often different in each aperture sharpness.
