Sigma Macro ประวัติและเรื่องราว

เรื่องราวของเลนส์

The Sigma 105mm 1:2.8 DG OS Macro HSM is the full-frame, image-stabilized macro that Sigma released in 2011, and the Sony/Minolta Alpha (A-mount) version is the one that concerns A-mount shooters. It arrived into a market where the closest rival — Nikon's AF-S Micro Nikkor 105/2.8G — was already five years older, so Sigma positioned this as a modern 1:1 macro that doubled as a short telephoto portrait lens and a tool for compressed landscapes and candid work. It sits in a small family: a predecessor, the Sigma 105mm F2.8 EX DG Macro from 2004 (no OS, no HSM), preceded it, and a mirrorless-only successor, the Sigma 105mm F2.8 DG DN Macro Art (2020, Sony E and L-mount), followed it. The A-mount and Sony SA versions were eventually discontinued, while Nikon F and Canon EF remained in production for years. No established nickname or community jargon (no 'Bokeh Monster', 'Radioactive' or similar) appears in the reviews for this lens — it is known simply by its designation. Its following is rooted in pragmatism rather than mystique: reviewers note it has 'a good reputation,' and because of its age it can be found relatively cheap used, making it strong value for money for a true 1:1 macro with stabilization.

สรุป: This is a practical, high-resolution 1:1 macro for the photographer who values clean sharpness and pleasing subject isolation over vintage character. Reviewers consistently praise it as very sharp with beautiful bokeh, and the A-mount DG OS version adds stabilization and a focus limiter that make handheld macro and portrait work genuinely usable. It is not a swirly, glowing 'character' lens — it renders detail faithfully — so it best suits macro shooters, nature and product photographers, and portraitists who want dependable, affordable precision rather than optical drama. Its main compromises are a plasticky feel and below-average autofocus speed.

รีวิวจากผู้ใช้

ข้อดี

Exceptional sharpness — reviewers call it 'exceptionally sharp' and capable of 'super sharp' results, especially in close-up macro work
True 1:1 macro magnification that doubles effectively as a short-telephoto portrait lens
Beautiful, pleasing bokeh from the f/2.8 aperture with 9 rounded blades for subject isolation
Built-in optical stabilization (OS) with a dedicated switch offering full and vertical-only modes — useful for handheld close work
A three-position autofocus limiter that lets you restrict the focus range and speed up focus acquisition
Solid, reputable build and strong value for money, particularly cheap on the used market given its age

ข้อเสีย

Autofocus is slower than average despite the quiet, precise ring-type ultrasonic (HSM) motor
The barrel is mainly plastic and feels 'plasticky,' even if solid in hand
It is a large, fairly heavy lens (700 g) for its class

เทคนิคการใช้

Use the three-position focus limiter to restrict the focus range for your subject — it meaningfully speeds up the otherwise slow autofocus
Engage OS for handheld close-ups, and switch to the vertical-only mode when panning to keep intentional motion
Stop well down (toward f/8–f/11 or beyond) for macro subjects, since depth of field is razor-thin at 1:1 and f/2.8
For the sharpest macro frames, add controlled light — an off-camera flash steadies exposure and lets you use a smaller aperture
At f/2.8 lean on the lens as a portrait tool, using its shallow depth of field to isolate the subject
Override autofocus with the wide manual ring for precise focus placement in critical close-up work
