Overview
The TTArtisan 50mm f/0.95 is a fast, manual prime lens from Chinese optics manufacturer TTArtisan. It is not lighting or grip equipment, but a camera lens. Its extremely wide maximum aperture of f/0.95 allows for shooting in very low light and produces a distinctly shallow depth of field with soft bokeh – an affordable counterpart to classic high-speed optics like the Leica Noctilux.
Under the designation "50mm f/0.95", TTArtisan offers two different products that should not be confused:
- Full-frame variant (M 50mm F0.95 ASPH): Rangefinder lens with Leica M mount, covers full-frame (35mm film format).
- APS-C variant: Significantly more affordable lens for mirrorless system cameras (e.g., Fujifilm X, Sony E, Nikon Z, Canon RF, L-Mount, MFT); crops to a 35mm equivalent field of view of approximately 75mm on a 1.5x crop sensor.
Both are purely mechanical: manual focus and manually set aperture, with no electronic contacts to the camera.
Technical Data
Specifications for the Full-frame variant M 50mm F0.95 ASPH (Leica-M) according to manufacturer data and independent tests:
| Feature | Value |
|---|
| Focal Length | 50 mm |
| Maximum Aperture | f/0.95 |
| Minimum Aperture | f/16 |
| Optical Construction | 11 elements in 8 groups |
| Aperture Blades | 14 |
| Minimum Focus Distance | 0.7 m |
| Mount | Leica-M |
| Image Circle | Full-frame / 35mm film format |
| Weight | approx. 687 g |
| Focus | Manual only |
The APS-C variant is smaller and lighter (around 411 g), uses a simpler optical design, and has fewer aperture blades. It is offered for various mirrorless mounts.
Use on Set
On film sets, the TTArtisan 50mm f/0.95 is used as an affordable, fast lens for available light and low-light situations, as well as for stylized shots with a very shallow plane of focus. As it is entirely manual, it is suitable for classic hand-focus workflows with a follow focus; there is no electronic aperture control or lens data transmission to the camera. At maximum aperture, soft rendering with lower contrast and visible aberrations are typical – a character that can be used creatively, but is reduced for technically clean shots by stopping down (e.g., to f/5.6–f/8).
