Yes, street photography. I don't normally favour abbreviations, but as it's the Street sub forum I assumed SP wouldn't require explanation as it's routinely used.
The rule of thumb I've always adopted is allow one third in front of hyperfocal and two thirds behind to be sharp. In a street environment one has to play the odds to a certain extent, and refocus if something is well out of range. My 2.8 Industar shows a focal setting of 2.5 metres at f8 to give approximately 1.8m (5ft 11in) to 3.75m (12 ft), or put another way 2/3 length figures to small groups on a 50mm lens. So long as that photographic "template" is born in mind, one can point and shoot to the heart's content.
f11 show 5' 6" to almost 15ft sharp, at the same 2.5m focus setting. These will of course show reasonable sharpness for closer and further objects, especially the latter. The compromise with 50mm lenses is they allow greater magnification at the expense of depth of field, which is why many street photographers go wider, including myself. However looking back at my work over the years I prefer the perspective of 50mm lenses to 28mm ones. Currently I'm using 1/250 at f8 and rating the film as necessary for the day, between 400 and 1600 ASA.
