Why I Only Shoot F8
Okay, I do not only shoot f8. Though, it is a core principle I follow.
I believe many photographers, especially early on, end up using their camera to show what their camera can do. The sharpest bokeh, the cleanest high-ISO, the fastest autofocus. And I get it. Gear is exciting and new capabilities feel worth showing off. But the camera is not the point. The idea is. Everything about how you set it up should serve what you are trying to say, not the other way around. f8 is part of that for me.
Sharpness
Most lenses, regardless of price, hit their optical sweet spot somewhere between f5.6 and f11. Wide open at f1.4 or f2, you get chromatic aberration, soft edges, focus falloff. Stop down too far to f16 or f22 and diffraction creeps in. Right around f8, you get the cleanest image your lens is capable of: sharp corners, strong contrast, no tricks.
And because f8 has a wide depth of field, more of the scene around your subject stays in focus too. The room, the background, the context. Many photographers treat this as a problem. I think it is actually the whole point. You are not staging a portrait against a blur. You are documenting someone inside their world.
One shot with flash, one without. Both portraits, but with different intentions. One pulls the environment in; the other keeps focus on the person, though you can still see the flowers and the design behind him.
Range Focusing
At f8, your depth of field is large enough that if you pre-set your focus distance, say three metres, anything from roughly two to five metres will be sharp. This is called zone focusing, and it is how many street and documentary photographers work.
In practice, it means you can raise the camera and shoot without hunting for focus at all. You already know what will be sharp. That speed is not about reflexes. It is about removing a mechanical step so your attention stays on the scene, not the viewfinder.
One less thing
When I am working manually, I am managing shutter speed, ISO, focus, and composition all at once. This is a lot to think about and it takes you out of the moment, out of the scene. Fixing aperture at f8 means one fewer dial to touch. It sounds small, but it is life changing to be able to think about one less thing and focus your energy elsewhere, in more creative departments.
The camera should disappear. The moment you are spending mental energy on settings, you are spending it somewhere other than the person in front of you. f8 stays set so my attention does not have to move.
the subject is as important as the environment it is in.
Shooting wide open
f2 has a place. Low light sometimes demands it. Certain portraits genuinely benefit from a shallow plane of focus. I am not saying never use it.
Shooting wide open is often the move photographers make when they do not yet have a strong idea. Bokeh is visual noise that reads as "intentional" even when it is not. It is a way of making an average composition look considered. But if you look closely, all it has done is remove the background. It has not added anything.
Go back to the idea of the camera as a tool and the idea behind your intentions. If your idea genuinely needs a shallow depth of field to work, if the blur serves the story, then use it. But if you are reaching for f1.8 because you want the photo to look like it was taken on a nice camera, that is the gear talking, not you.
The question to ask before you shoot is not what your camera can do. It is what you are trying to say. f8, most of the time, just gets out of the way and lets you say it.
Intentionality
Every setting is a choice, and every choice is an argument about what matters. Aperture, shutter speed, where you stand, when you press. None of it is neutral. The camera does not make decisions. You do.
f8 is not a rule I follow blindly. It is where I keep landing when I strip away the decisions that do not serve the image. What stays is the scene, the person, the moment, and a camera quiet enough to let me work.
That is what the camera is. A tool for getting an intention across. If you know what you are trying to say, the settings follow. If you do not, no aperture will save you.
The same logic carries over to other dials. I have written about overexposing film for the same reason: one less thing to think about while the moment is happening.
Why do street photographers use F8?
F8 gives you enough depth of field to zone focus, pre-setting your focus distance so anything within a few meters is sharp without hunting for focus each shot. Combined with the optical sweet spot of most lenses, you get the sharpest image your glass can make and the speed to raise and shoot without thinking about focus at all.
Is F8 the sharpest aperture on any lens?
Most lenses, regardless of price, hit their optical peak somewhere between f5.6 and f11. Wide open, you get chromatic aberration and soft edges. Stop down past f16 and diffraction softens the image. F8 sits in the middle: maximum corner sharpness, strong contrast, no optical tricks.
What is zone focusing and how does it work?
Zone focusing means pre-setting your focus distance before you raise the camera — typically two to three metres — and relying on the depth of field at your chosen aperture to keep everything in that range sharp. At F8, depth of field is wide enough that you can raise the camera and shoot without hunting for focus. It removes a mechanical step so your attention stays on the scene.
When should you shoot wide open instead of F8?
When low light genuinely requires it, or when the blur specifically serves the image. Shallow depth of field is a tool — if it helps the photograph, use it. But reaching for f1.8 because you want the image to look intentional, rather than because the blur adds something, is the gear making the decision for you.
Does using F8 all the time limit your photography?
It limits your options, and that is the point. Fixing aperture removes one variable so your attention goes somewhere more useful. Most of the photographs that matter in documentary and street photography were made at F8 or close to it. The constraint does not limit the work. It focuses on it.
