10. Focusing

The 28 mm focal length on full frame gives you already plenty of possibilities if you want to manage without autofocus. In fact, with a bit of experience the lack of autofocus won’t be felt at all. Even working at the maximum relative aperture we will get a sharp image from 5.45 meters to over 63 meters, choosing a 10-meter marking on the distance scale. When we set the scale at 5 meters, we will have the comfort of sharp image in the range from 3.5 to 8.6 meters.

On stopping down the situation gets swiftly better. For instance by f/4.0 the distance scale setting of 5 meters gives us a sharp picture from 2.8 meters to over 25 meters. Using the f/8.0 aperture we can practically forget about focusing. It’s enough to set the scale at 3 meters and enjoy a sharp image from 1.6 meters to over 68 meters.

Of course a clear and distinct depth of field scale, which can be found on the lens’s barrel, is simply priceless during focusing. You can examine it closer in the photo below.
