The Sony FE 100mm f/2.8 STF GM OSS is one of the most specialized and cinematic primes in the entire G Master lineup. This lens exists for productions where image texture matters more than anything else—beauty close-ups, luxury commercials, fashion campaigns, high-end interviews, dramatic telephoto portraits, and product hero shots requiring both clarity and character.

While labeled as f/2.8, the lens uses Sony’s Smooth Trans Focus (STF) apodization optics, delivering bokeh that no other stills or cine lens can replicate. Instead of harsh edges or nervous circles, the STF bokeh has a natural gradient fade, a softness that feels closer to high-end vintage cinema glass than modern clinically sharp primes.

For filmmakers shooting in Thailand—Bangkok beauty studios, Phuket fashion campaigns, Chiang Mai documentaries, island luxury brand work, premium hotel content—this lens provides a signature look you simply cannot achieve with standard primes.

Why Filmmakers Choose the 100mm STF GM for Video

1. The Best Bokeh Sony Has Ever Produced

The apodization element inside the lens acts like a built-in diffusion filter for out-of-focus areas.

The result:

• extremely smooth, velvety background blur

• zero onion rings

• perfect roundness at all T-stops

• cinematic separation without aggressive sharpening

For beauty cinematography and commercial close-ups, this is one of the most unique looks you can rent.

2. G Master Sharpness With Organic, Film-Like Rendering

Unlike some ultra-sharp lenses that feel overly digital, the STF GM balances:

• high center sharpness

• controlled micro-contrast

• soft, elegant highlight rolloff

• realistic skin tones

Interview content in Thailand—studio, hotel rooms, corporate sets—benefits enormously from this combination.

3. Optical SteadyShot (OSS) for Handheld and Slow Motion

Telephoto primes often require heavy rigs, but the 100mm STF includes OSS stabilization, making it usable for:

• handheld Burano shots

• FX3 / FX6 slow-motion portraits

• doc sequences using only a monopod

• gimbal setups using RS4 / RS3 This makes it extremely practical for run-and-gun commercial and documentary work.

4. Perfect Focal Length for Beauty, Fashion & Interviews

100mm is the sweet spot for:

• facial close-ups with zero distortion

• beauty work and makeup commercials

• e-commerce fashion

• portrait inserts

• emotional, cinematic interview compositions

• food/product hero shots

In Thailand’s competitive beauty and advertising market, this lens creates a look directors immediately respond to.

5. APO-like Color & Minimal Aberration

The optical design includes:

• apodization element

• ED glass

• dual linear motors

• floating focus system

The result is clean highlight transitions, minimal fringing, and premium color consistency across G Master lenses—ideal for multi-camera setups.
