Olympus Olympus Macro 50mm f3.5 Heritage

Overview

The Olympus OM Zuiko Auto-Macro 50mm f/3.5 was first released in 1973 as part of Olympus's OM system, which was renowned for its compact and lightweight design philosophy. According to the phillipreeve.net review, there are three practical versions: the original single-coated 'Olympus OM Zuiko Auto-Macro 1:3.5 f=50mm' (1973, some with silver nose), the multicoated 'Olympus OM Zuiko MC Auto-Macro 1:3.5 f=50mm', and the last version 'Olympus OM Zuiko Auto-Macro 50mm 1:3.5' which is multicoated with probably updated coatings but no MC engraving. All three share the same 5-element/4-group optical design with floating elements. No established nicknames or community jargon are documented in these reviews. The lens has a modest cult following owing to its small size, affordability (around $40-50 used), and the reputation of 'Olympus Colours' — one reviewer noted this signature is 'most definitely' real and 'not a myth.' Its unusually close 0.23m minimum focus distance and 0.5x maximum magnification make it a versatile creative tool that people appreciate for both macro and general-purpose walk-around use.

Verdict: The Olympus OM Zuiko Macro 50mm f/3.5 is a small, affordable, and genuinely sharp macro lens that delivers a distinctive Olympus color signature and versatile rendering. It suits photographers who want a compact do-it-all lens for both macro and walk-around use, and who appreciate creative control over bokeh character. Slower speed and hexagonal stopped-down bokeh are its main compromises, but at its typical ~$44 price it is an outstanding value. Buy a multicoated copy and avoid the flare-prone single-coated first version.

Optical Character

Bokeh

Smooth and buttery at macro distances, shifting from bubble bokeh wide open to obvious hexagonal shapes when stopped down.

Color

Distinctive cool 'Olympus Colours' that lean toward purple rather than green.

Sharpness wide open

Highly regarded, sharp even wide open and described as just as sharp at f/3.5 as at f/8.

Flare resistance

Good for its age with light sources in-frame, but veils badly with a strong light just outside the frame; single-coated version flares heavily.

Community Insights

What people love

The distinctive 'Olympus Colours' signature and excellent color rendition
Sharpness that holds up wide open and rivals its stopped-down performance
Very small, compact, lightweight (200g) and well built with great handling
Excellent value — typically around $40-44 used
Close 0.23m minimum focus distance and 0.5x magnification make it a creative, versatile lens
Smooth, buttery bokeh at macro distances, with the ability to vary between bubble and hexagonal character
The front element sits deeply recessed and is well protected from flare and damage, so it can be carried without a cap or hood
One of the best aperture ring designs one reviewer had encountered

What people dislike

Hexagonal bokeh becomes obvious and can be distracting when stopped down due to 6 straight aperture blades
Significant veiling flare when a strong light source sits just outside the frame
The transition zone in out-of-focus areas isn't very smooth at normal distances
Relatively slow at f/3.5 for non-macro applications
On Pentax bodies an OM adapter with an extra corrective element is required, which affects performance
Steep focusing throw (only ~40 degrees from 1m to infinity) makes precise focus at distance trickier
The original single-coated version flares a lot and is best avoided

Pro Tips

Shoot wide open at f/3.5 to keep bokeh rounded and smooth; be aware that stopping down to f/5.6 or f/8 makes the hexagonal aperture shape obvious
Watch for strong light sources just outside the frame — they cause significant veiling flare; reposition or shade the lens
Take advantage of the 0.23m close focus and 0.5x magnification for creative near-macro compositions even in general shooting
Prefer a multicoated version (MC engraved or the later no-MC multicoated variant) for better flare control
On Canon and mirrorless bodies use a simple adapter without corrective glass to preserve the lens's full performance
The recessed front element means you can generally shoot without a hood or cap
