From my experience of SLR and DSLR cameras, if you want a good depth of field you usually need to shoot at between f5.6 upwards to f11. But it depends upon the light and the distance to the objects you want in focus and of course the actual lenses used. Diffraction effects usually are not so noticeable in darker images and allow larger f numbers to be used to great effect. It has born me out over the last 45 years of photography with all sorts of cameras anyway, with some decent shots. just my two pence worth anyway. ![Smile :) :)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
