Depth of Field Calculator for Street Photography

Street photography rarely allows time to focus precisely on a fast-moving subject — zone focusing, pre-setting an aperture wide enough to cover a range of likely distances, is what makes a candid moment catchable at all.

Recommended settings

Typical street zone-focus setup: f/8-f/11 at 28-35mm, focused around 2-3m, covers most candid subject distances without refocusing.
Tighter, more selective shots: f/2.8-f/4 for background separation when there's a moment to compose more deliberately.

Tips for this niche

Check the near and far limits at your chosen aperture and focus distance before heading out, so you know the actual 'safe zone' a subject can appear in without refocusing.
A wider aperture zone-focus setup needs a shorter safe-zone range — narrow the aperture further if subjects are likely to vary widely in distance.

Example scenario

Working a busy market street, setting focus at 2.5m and f/8 at 28mm gives roughly 1.5m to 5m of usable sharp zone — wide enough to catch a passerby at several different distances without refocusing for each shot.

Common mistakes

Zone focusing at too wide an aperture for the technique to be forgiving. a very shallow depth of field leaves almost no margin for a fast subject stepping slightly closer or further than the preset focus distance.
Not rechecking the zone when changing locations. a zone-focus setup calculated for a wide plaza won't cover a narrow alley's much closer typical subject distance — recheck per location.
