Zenitar 16mm f/2.8 centre sharpness

Centre sharpness test
Article text
Let's start with the good news - used at apertures betweeen f/4 and f/11, the sharpness at the centre of the image is actually pretty good. Wide open at f/2.8 it's pretty appalling, though!
Just as you'd expect, at smaller apertures the sharpness starts to suffer as diffraction starts to affect the image, with F/16 still being okay, but it's pretty soft at F/22.
Okay, so it's not going to win any pixel-peeping contests, but it's still a good, useable lens at the middle aperture settings. The results wide open are technically awful (take a look at the edge results if you need any more proof!). But on a more aesthetic level the soft, hazy results have a use - not every shot needs to be technically perfect to be a good photo, and I think it actually adds to the fun aspect of using a fisheye lens.
