I think David is mistaken or has mistyped. With a slow lens you have lots of depth of field *control*: the depth of field is small which means you can use it to isolate elements of the composition. However, you must have good control of the focus to achieve this. Not what you want for point and click, and not what you want when you can't see a viewfinder image with the same resolutiuon as the final image. Of course, one point I didn't mention - the depth of field is also proportional to the resolution of the image sensor - if that is low, then the depth of field is effectively increased, in that the image is equally soft either side of the focus point.
