Zoom lenses in the OM era were never meant to be the stars of the system. They were practical, ambitious, occasionally awkward things – built with good intentions, clever ideas, and varying degrees of success.
Olympus, bless them, tried their best.
Some OM zooms are perfectly decent.
Some are genuinely clever.
And some behave like they escaped from a lab before anyone finished the paperwork.
Here is the official Zuikography guide to the Zuiko Zooms – affectionate, honest, and exactly as chaotic as the lenses themselves.
The Zuiko 35-70mm Club (The Reasonable Branch)
35–70mm f/3.5–4.5 – The Friendly, Mildly Underwhelming One
Tries very hard. Produces perfectly acceptable images. Never offends.
Personality traits:
- arrives on time
- brings a salad
- works fine if you ignore the corners
Rendering:
Surprisingly okay. Sometimes good. Never great.
Like a sitcom you watch because it’s on.
35–70mm f/3.6 – The Unexpectedly Good One
Nobody ever talks about this lens and it’s honestly quite rude because it’s actually decent.
Personality traits:
- undervalued
- unassuming
- quietly produces better results than it looks like it should
Rendering:
Respectable sharpness, better contrast than expected, and not offended by backlight.
This is the zoom equivalent of the sensible friend with a hidden PhD.
The 75-150mm Club (The Surprisingly Charming Uncle)
75–150mm f/4 – The Budget Telephoto That Refuses To Die
Everyone has owned one.
Nobody remembers buying it.
They simply appear in camera bags the way socks appear behind radiators.
Personality traits:
- competent
- lighter than it should be
- full of “that’s actually not bad” surprises
Rendering:
Decent sharpness and surprisingly lovely colour.
Never spectacular, but never insulting either.
A beloved uncle who brings the nice biscuits.
The 28–48mm Experiment (Science Gone Wrong or Right?)
28–48mm f/4 – The Zoom That Thinks It’s Two Primes
One of Olympus’s more elegant ideas:
a compact wide-to-normal zoom that behaves sensibly, fits in a jacket pocket, and doesn’t ask too many questions.
Personality traits:
- tidy
- competent
- unfazed by anything
Rendering:
Better than it has any right to be.
The optical equivalent of a cup of tea that fixes your whole afternoon.
The Superzooms (The Agents of Pure Chaos)
35–105mm f/3.5–4.5 – The One That Bites If Startled
Sometimes sharp.
Sometimes soft.
Sometimes flares like it’s being interrogated.
Personality traits:
- unpredictable
- dramatic
- deeply charming on its good days
Rendering:
When it works: lovely.
When it doesn’t: you will learn to swear in languages you do not speak.
75–260mm f/4.6 – The Victorian Telescope
Long. Heavy. Slightly absurd.
Feels like something you’d use to spot ships approaching Portsmouth.
Personality traits:
- overconfident
- eccentric
- excellent for upper-body strength
Rendering:
Surprisingly atmospheric if you can hold it steady long enough to take the shot.
65–200mm f/4 – The Forgotten Middle Child
Lives in attics.
Found in charity shops.
Better than people remember.
Personality traits:
- neglected
- decent
- confused why nobody calls anymore
Rendering:
Perfectly usable if you treat it kindly.
The Rare & Interesting Ones
35–80mm f/2.8 – The Unicorn
The exotic, expensive, optically serious Zuiko zoom.
So rare it may not actually exist; could simply be a rumour started in 1984.
Personality traits:
- elite
- mysterious
- probably owns a vineyard
Rendering:
If you ever find one, congratulations – you’ve achieved enlightenment.
The rest of us will continue speculating.
ED & High-Grade Zoom Experiments
Olympus made a few special optical prototypes and small-run lenses during the OM years.
These are:
- technically brilliant
- practically unobtainable
- essentially the zoom equivalent of celebrity sightings
You won’t own them, but it’s nice to know they’re out there somewhere, rehearsing for their comeback tour.
The Zoom Family Dinner
- The 35–70mm brings the bread and behaves.
- The 28–48mm organises the seating plan.
- The 75–150mm tells stories from the 70s.
- The 35–105mm knocks over a drink.
- The 75–260mm stands at the end of the table due to structural concerns.
- The 35–80mm f/2.8 arrives late, dressed impeccably, says little, eats little, leaves early.
- The 65–200mm sits quietly next to the radiator.
It’s chaos.
It’s lovely.
It’s the OM zoom family.
