Samyang AF 75MM F1.8 SONY FE

Samyang AF 75mm F1.8 Sony FE – Lightweight 230g portrait lens with f/1.8 aperture

The Samyang AF 75mm f/1.8 FE joins the "Tiny but almighty" series as a compact portrait lens for Sony full-frame mirrorless cameras. It combines a bright f/1.8 aperture with a lightweight and short design, making it a practical choice for photographers and videographers who need a portable, high-quality optic.

Compact design for on-the-go portrait and wedding work

The "Tiny but almighty" series debuted in 2017 to meet demand for lighter lenses with strong optical performance for mirrorless systems. This 75mm is the fifth member of that series and targets portrait and lifestyle photographers. Because it is lightweight and compact, it suits shooters working on location.

• Weight: 230g, keeping gear light for long shoots.
• Length: 6.9 cm, making it easy to carry and balance on small camera rigs.
• Designed for full-frame sensors but also works well on APS-C bodies.

Optical design for sharp images and creamy bokeh

Samyang emphasises optical design to create a pleasing bokeh and high image quality. The lens uses a total of 10 elements in 9 groups and includes five special elements that reduce aberrations and maintain sharpness.

• 10 elements in 9 groups.
• 5 special elements: 3 extra low dispersion elements and 2 high refractive elements.
• 9-blade aperture that produces a circular out-of-focus rendering together with the optical design.

Fast, quiet and accurate autofocus with STM

The lens delivers fast and stable autofocus thanks to a new linear stepping motor (STM). The motor operates quietly and precisely, which benefits both stills photographers and videographers.

Consequently, the AF performance suits the fast and changeable situations commonly encountered at weddings and during portrait sessions with children, where speed and reliability are essential.

Custom aperture control via focus ring and firmware

This model introduces a custom switch that lets you control the aperture using the focus ring when the switch is engaged. You can also change the custom switch function to suit your workflow via firmware—using the Samyang Lens Station.

Key use cases

1. Portrait and lifestyle photography where a compact, high-quality lens is preferred.
2. Wedding photography that requires fast handling and lightweight gear.
3. Video work that benefits from quiet, accurate focusing and smooth aperture control.
