The Carl Zeiss Distagon T* 25 mm f/2.0 ZE/ZF.2 is a fully manual lens so you have to set the focus on your own. Its manual focus ring helps a lot as it is of high build quality and it works perfectly well, especially that it is equipped with a useful depth of field scale.

Carl Zeiss Distagon T* 25 mm f/2.0 ZE/ZF.2 - Focusing

Although we deal here with an ultra wide angle lens the focusing at the maximum relative aperture is hardly easy because the depth of field is not large. For example setting the focus at 2.5 meters we get a sharp image in the range of 2.02-3.28 meters. The situation improves quickly on stopping down the aperture. By f/4.0, when the focus is set at these 2.5 meters, the depth is already over 3 meters large and by f/5.6 – it becomes over 6 meters large.
