Olympus mju / Stylus Buyer's Guide: what 'mju II' actually means

The Olympus mju is the most talked-about film compact of the moment, and the one most often bought by mistake. Both facts come from the same cause: "mju" and "mju II" are family names, not camera names, and the family contains cameras that share a badge and almost nothing else.

The line began in 1991, designed by Yoshihisa Maitani — the same engineer behind the XA — and it carries the XA's central idea forward. A curved clamshell covers the lens, and sliding it open switches the camera on. Everything else was made to disappear: no dials, no settings, a body that a coat pocket forgets about. Olympus sold millions of them.

The thing most buyers miss

The camera people mean when they say "the mju II" is the 1997 mju II, also sold as the Stylus Epic: a fixed 35mm f/2.8 lens, four elements in four groups, weatherproof, 135 g. That is the one with the reputation, and the price that goes with it.

But Olympus also sold a whole range of zoom cameras under the same names — the mju Zoom 105, 115, 130 and 140, and the mju-II Zoom 80, 115, 140 and 170. They look similar at a glance and the badge on the front says μ[mju:]-II just the same. Their lenses do not compare:

Model	Lens	Maximum aperture
mju II (Stylus Epic), 1997	35 mm fixed	f/2.8
mju (Stylus / Infinity Stylus), 1991	35 mm fixed	f/3.5
mju-II Zoom 80	38–80 mm	f/4.5–8.9
mju Zoom 105	38–105 mm	f/4.5–8.9
mju Zoom 115 / mju-II Zoom 115	38–115 mm	f/4.5–9.7
mju Zoom 130	38–130 mm	f/4–10.3
mju Zoom 140	38–140 mm	f/4–11

At the long end of a mju-II Zoom 80 you are shooting at f/8.9 — more than three stops slower than the f/2.8 of the prime. Indoors and at dusk that is the difference between a usable frame and a flash photograph. The zooms are pleasant cameras used in daylight, and they are far cheaper for the good reason that they are not the same thing. Buying one because the badge says "mju II" is the single most common mistake in this corner of the market.

How to tell them apart in a listing photograph

Ignore the title and read the front of the lens barrel. It is printed on every one of these cameras:

• "OLYMPUS LENS 35mm 1:2.8" — the mju II / Stylus Epic. The famous one.
• "OLYMPUS LENS 35mm 1:3.5" — the original 1991 mju / Infinity Stylus.
• "ZOOM 38–80 mm" (or 105, 115, 130, 140, 170) — a zoom model, whatever the badge on the body says.

The shape gives it away too: the primes are flat-fronted and plain, while the zooms carry a large protruding barrel that the clamshell has to arch over. If a listing shows neither the barrel marking nor the model plate, ask for a photograph of both before you buy.

The two primes, compared

The 1991 mju has a three-element 35mm f/3.5, a shutter from 1/15 to 1/500, DX coding to ISO 3200, and a 100-step active autofocus that was genuinely advanced for its moment. It is the purer object of the two: smaller-feeling, quieter, and with a rendering that is softer and gentler than the later camera. A Panorama version followed in 1992 with a switchable film mask.

The 1997 mju II is the more capable camera in every measurable way: a four-element 35mm f/2.8, a shutter that runs from 1/1000 all the way out to 4 seconds, an automatic exposure range of EV 1–17, focusing to 0.35 m, spot metering, a night-scene flash mode with slow sync, and a weatherproof shell. At 135 g it weighs less than a phone.

If you can find a good mju II at a price you are willing to pay, it is the better camera. If the hype has priced it out of reach, the 1991 mju is the one to look at — it does most of the same things, in the same pocket, for a fraction of the attention.

Why shoot one today

The clamshell, again. This is the XA idea carried into the 1990s. Closed, the lens is sealed and the camera cannot fire; open, it is ready. No cap, no bag, no decision. It is the reason these cameras end up in a coat pocket for a whole winter.

The autofocus actually works. Active multi-beam with a hundred steps on the original, focus lock on the mju II. After the centre-only, three-zone systems of the early 1980s, this generation is the first where you can simply trust the camera.

Modern film speeds. DX coding to ISO 3200 means the fast film that is actually on sale today works properly, which is not true of every classic compact.

The mju II is weatherproof. Splash resistant, not submersible — but it is a camera you can keep shooting in rain, which almost nothing else in this class offers.

It is genuinely small. 108 × 59 × 35 mm and 135 g for the mju II. Not "compact for a film camera": small.

Know before you shoot

• There is no manual control at all. No aperture, no shutter speed, no exposure compensation. If you want to make decisions, the Olympus XA is the camera in this shop that lets you.
• The flash resets to automatic every time you close the barrier. If you want it off, you must suppress it again on the next power-up. Many a quiet moment has been lit by accident this way.
• The battery is a CR123A lithium. Still made and still sold, but it is not a AA you can buy at a village shop, and a dead one stops the camera completely.
• The zoom models are slow. At f/8.9 or f/11 at the long end they need daylight or flash. Judge them as daylight cameras, which is what they are.
• The electronics are the weak point. These are fully electronic cameras from the 1990s. When one fails it is usually the LCD, the zoom motor or the shutter, and none of those are a clean-and-return job.
• The mju II's reputation has outrun it. It is an excellent camera. It is not three times better than the 1991 mju, and it is not better than an XA at the things an XA does.

How to shoot it well

1. Suppress the flash first, every time you open it. Make it a reflex, the way closing the barrier is.
2. On the mju II, use the spot meter. It is the only exposure control you have, and against a bright background it is what saves the face.
3. Load ISO 400 as a default, and ISO 800 for a zoom model. These cameras read DX properly, so let the film do the work the aperture cannot.
4. Get close. 0.35 m on the mju II is closer than most compacts of any era, and it is where the lens is most fun.
5. Use the night-scene mode on the mju II rather than the standard flash after dark. Slow sync to four seconds keeps the background instead of punching a hole in it.
6. Carry a spare CR123A. One cell, no warning, no mechanical fallback.

Where it sits among its rivals

The mju is the end point of the line that begins with the Olympus XA: the same clamshell idea, with every remaining decision taken away from you. The XA gives you focus and aperture; the mju gives you speed and certainty. The Canon Autoboy and the Nikon L35 are a decade older, larger and louder, with lenses that have more character and less consistency. If you want one camera that will simply come back with the picture, this is the family.

What to check before you buy

1. Which model it actually is. Ask for a photograph of the front of the lens barrel. This is the first question, not the last.
2. Power. A fresh CR123A, and the camera should wake as the barrier opens, every time. There is no mechanical mode to fall back on.
3. The barrier. It should slide smoothly and switch the camera cleanly on and off. A barrier that has to be helped is a camera that has been dropped.
4. The zoom (zoom models). It should run in and out smoothly through the whole range without hesitating or grinding. Zoom motors are a known failure.
5. The LCD panel. Missing segments or a faded display are common and are not repairable in practice.

6. Flash and autofocus. The flash should charge in a few seconds, and the focus confirmation should respond to near and far subjects.
7. Shutter and film transport. Ask whether the seller has run an actual test roll. On a fully electronic camera that is the only way to know it works across a whole roll rather than once on a bench.

8. The lens. Ask for dust, fungus, haze and cleaning marks to be reported separately, not as "clean" or "good condition". In our experience light dust and slight fungus almost never appear in photographs, and slight haze usually shows only when shooting into the light. Heavy haze or fungus is a different matter, and we grade it as such.
9. Light seals. We replace deteriorated seals before a camera is listed.

How we grade and test

Every mju we list has been through the checks above. We run a test roll to confirm the shutter and the film transport, replace light seals that have deteriorated, and report each function on the product page as Works properly or Not working, with dust, fungus, haze and cleaning marks reported separately. We also state the exact model and the lens marking, so there is no ambiguity about which camera you are buying. The full explanation is on our Grading & Inspection page.

Tested or "as is"?

These are the most electronic cameras we sell, and the least forgiving of a gamble. A failed zoom motor or a dead LCD is not a cleaning job, and an untested body gives you no way to tell. For a repairer with parts, an "as is" mju can still be worth having. For everyone else, buy one that has had a roll of film through it and a report to go with it.
