Olympus Olympus Macro 50mm f3.5 Heritage

เรื่องราวของเลนส์

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.

สรุป: 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.

คาแรกเตอร์ของภาพ

โบเก้

ในระยะมาโครให้โบเก้ที่เนียนนุ่ม — เมื่อเปิดรูรับแสงกว้างสุดจะเป็นโบเก้แบบฟอง แต่เมื่อหรี่รูรับแสงจะเปลี่ยนเป็นรูปหกเหลี่ยมที่เห็นได้ชัด

โทนสี

โทนสีเย็นอันเป็นเอกลักษณ์ของ 'Olympus Colours' ที่มีแนวโน้มไปทางสีม่วงมากกว่าสีเขียว

ความคม (เปิดสุด)

เป็นเลนส์ที่ได้รับการยกย่องอย่างสูง มีความคมชัดแม้เมื่อเปิดรูรับแสงกว้างสุด และให้ความคมชัดเท่ากันที่ f/3.5 และ f/8.

แฟลร์

เมื่อเทียบกับอายุของเลนส์ถือว่าทำได้ดีเมื่อต้องมีแหล่งแสงอยู่ในเฟรม แต่จะเกิดม่านแสงฟุ้งอย่างรุนแรงเมื่อมีแสงจ้าจากนอกเฟรม และรุ่นที่เคลือบชั้นเดียวมีแฟลร์มาก

รีวิวจากผู้ใช้

ข้อดี

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

ข้อเสีย

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

เทคนิคการใช้

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
