Quick intro
The OM-1 gives you an excellent electronic viewfinder (EVF), a fully articulating rear LCD, and an eye sensor that can switch between them automatically. That flexibility is useful—until the camera changes display at exactly the wrong moment.
This guide explains how the EVF/LCD switching works, how to choose a field-friendly setup, and how to avoid the classic “why did my screen just go black?” experience. You will also get practical starting settings for fast shooting and deliberate low-angle work.
The idea (no mythology)
- The small sensor beside the viewfinder detects when something comes close to it and can activate the EVF automatically.
- With EVF Auto Switch on, bringing the camera to your eye normally changes the display from the rear monitor to the EVF.
- A hand, jacket, camera strap, or your body can trigger that sensor too. It is not haunted; it is simply enthusiastic.
- With EVF Auto Switch off, the camera will not change displays automatically. You choose EVF or monitor manually using the display button.
- The OM-1 also lets you decide what the EVF should show when it switches: continue with the current screen or jump straight to the shooting display.
- Your best setting depends less on “correct technique” and more on how you actually work: eye-level shooting, low angles, tripod work, reviews between frames, or a mixture of all four.
The goal is not to make the camera clever. The goal is to make it predictable.
Know the two display choices
Before changing anything, separate the two jobs in your mind.
The EVF is usually best for hand-held photography. It blocks distracting light, helps you hold the camera steadily against your face, and makes framing in bright daylight much easier. It is the sensible default for action, wildlife, portraits, and any situation where the camera moves quickly from resting position to shooting position.
The rear LCD is ideal when the camera is away from your eye: low-angle scenes, overhead compositions, tripod work, discreet shooting, or photographing close to the ground without lying down beside a puddle. The articulating screen is one of those features that feels optional until you use it properly for a week.
The trouble starts when your chosen display is interrupted by automatic switching. If you regularly compose with the open LCD, an active eye sensor can be triggered while you move your hand near the viewfinder. If you shoot quickly from the eye, turning the sensor off can add an unnecessary button press before every sequence.
A simple field workflow
Choose your dominant shooting style before leaving.
If you expect fast, hand-held shooting, use automatic EVF switching. If you expect low-angle, tripod, or articulated-screen work, consider manual switching or make the open monitor your protected workspace.Set the eye sensor behaviour, then test it physically.
On the OM-1, openMENU > Monitor/Sound/Connection > Eye Sensor Settings. Test the camera with the LCD closed, open, tilted, and facing forward. Do not trust a menu setting until your hands and camera strap have tried to annoy it.Use one repeatable reset before important shooting.
Before a subject appears, look at the display icon/status, raise the camera to your eye once, then lower it. If the display changes exactly as expected, you are ready. This takes two seconds and prevents fumbling when the light or action becomes interesting.
Practical settings example
Scenario 1: Walking, wildlife, street, or family action
You are carrying the OM-1 at chest height and expect to raise it to your eye quickly.
Start here:
- EVF Auto Switch: On
- Behaviour when switched: Shooting Screen
- Rear LCD position: Closed against the camera body when practical
- EVF Auto Luminance: On
- Drive mode: Sequential Low at 5 fps for short action bursts
- Shutter speed: 1/1000 s for a moving person or medium-paced animal
- Aperture: f/4
- ISO: Auto ISO, with a sensible upper limit such as ISO 6400
“Shooting Screen” is the useful choice here because the EVF immediately gives you live shooting information even if you were reviewing a frame or browsing a menu on the rear LCD. That makes the camera feel quicker when a bird takes off, a child laughs, or a cyclist rides through your composition.
Keeping the monitor closed also reduces accidental sensor triggers. It is not mandatory, but it gives the camera fewer chances to become creatively confused.
Scenario 2: Low-angle landscape, macro, or tripod work
You have opened the LCD to compose near ground level or at an awkward angle. You want the monitor to stay active while you adjust focus, check the histogram, and wait for the right light.
Start here:
- EVF Auto Switch: Off
- Display selection: Choose LCD manually with the display button
- Rear LCD position: Open and angled for comfortable viewing
- Shutter speed: 1/60 s hand-held for a still subject, or 2 s on a tripod
- Aperture: f/5.6 for a close subject with some background separation, or f/8 for a landscape
- ISO: 200 for maximum image quality in good light
- Focus method: Single AF point or manual focus with magnification for precise placement
With automatic switching disabled, the eye sensor cannot interrupt your monitor view when your hand passes near the eyecup. This is especially pleasant for macro work, where small movements, an angled screen, and a close subject create plenty of opportunities for accidental switching.
For a tripod landscape, do not use the brightness of the LCD as your exposure meter. Check the histogram instead. A bright screen can make an underexposed file look fine; it has fooled many photographers before breakfast. The same principle applies to the EVF. For a quick refresher, see How to Read a Histogram for Beginners.
EXIF example
Example settings scenario — not real EXIF or real capture data:
A photographer is using the OM-1 for a low-angle close-up of a flower on an overcast day.
- Camera: OM SYSTEM OM-1
- Lens: M.Zuiko 60mm f/2.8 Macro
- Exposure mode: Aperture Priority
- Aperture: f/5.6
- Shutter speed: 1/250 s
- ISO: 400
- Exposure compensation: +0.3 EV
- AF mode: S-AF, small single point
- Display setup: Rear LCD open, EVF Auto Switch Off
The important lesson is not the exact numbers. It is that the photographer deliberately chose the LCD workflow first, then set exposure and focus without the camera unexpectedly swapping to the EVF.
Common mistake + how to spot it
The common mistake is leaving EVF Auto Switch on while shooting with an open LCD, then assuming the camera has a display fault when the monitor turns off.
You can spot this easily. Open the LCD, enter live view, then move your hand close to the viewfinder eyecup without touching the screen. If the camera switches to the EVF or the monitor appears to go dark, the eye sensor is doing its job—just not the job you want at that moment.
The fix is simple:
- Turn EVF Auto Switch off for LCD-led shooting, or
- Change the option that controls eye-sensor behaviour when the monitor is open, if your OM-1 menu provides it, so an open monitor is not interrupted.
Menu wording can vary slightly with camera generation and firmware, so use the behaviour rather than the label as your guide. Test it in your normal shooting position, with the strap attached. A setting that works on a kitchen table can behave differently when you are wearing a jacket and holding the camera at waist level.
Mini practice task (10 minutes)
Set a timer for ten minutes and photograph one simple subject—a mug, plant, bicycle, or window scene will do.
First, use the OM-1 with EVF Auto Switch On. Alternate between looking through the EVF, composing from the LCD, reviewing an image, and returning to shooting. Notice exactly when the camera changes displays.
Then repeat with EVF Auto Switch Off and manually select the LCD. Try one low-angle composition and one eye-level composition.
At the end, answer one question: which setup required fewer thoughts? Keep that one as your default. Camera settings should remove small decisions, not create a tiny daily debate.
Wrap-up
Use automatic EVF switching when speed and eye-level shooting matter; use manual display control when the open LCD is your main composition tool. Make the OM-1 predictable, check the behaviour before an important sequence, and you will spend less time arguing with the screen and more time making photographs.
