TTArtisan 11mm f/2.8 Fisheye

TTArtisan released this manual fisheye prime in 2022. It offers a single 11mm focal length in versions for Canon EF, Fujifilm G, Leica L, Leica M, Nikon F, Nikon Z and Sony E. Choose the version made for your camera. The Canon EF version covers full frame, and the measurements quoted here describe it.

An 11mm fisheye suits photographers who want an extremely wide view of tight interiors, architecture and the night sky. Straight lines near the edges bend strongly, so it rewards creative framing rather than a faithful record. The main trade-off is the fully manual design: you focus by ring, and the lens offers no stabilisation or sealing.

The Canon EF version measures 2.83 in (72 mm) across the front. No version takes a screw-in filter, so you cannot fit an ND or polariser directly.

At 11mm, this prime squeezes an entire room or courtyard into one frame. The fisheye design bends any straight line placed away from the centre, and the effect grows stronger toward the edges. Use that curve deliberately for dramatic skies and interiors. Leave this lens behind when a job needs straight walls.

The f/2.8 maximum aperture gathers useful light for dim interiors and night skies. Depth of field runs deep at 11mm, even wide open, so small focusing errors matter less. That forgiving depth of field makes the manual focus ring easier to use at speed. Precise work still rewards a slow check of focus before you shoot. The Canon EF version also uses 10 aperture blades. Stopped down, bright points such as stars or streetlights can form ten-ray stars.

The Canon EF version focuses as close as 0.8 ft (25 cm). You can press the lens toward a foreground object and let the fisheye curve stretch it across the frame. That near viewpoint gives interiors and sculptural details a strong sense of space. This lens scores 69/100 for optics on our specification measure.

There is no image stabilisation. The 11mm focal length partly offsets that, because tiny camera movements shift the frame far less than they would on a longer lens. Handheld shooting in reasonable light stays practical without stabilisation.

The lens carries no weather sealing and no fluorine coating. Nothing protects the joints from rain, sea spray or blowing dust, so keep it covered in poor conditions and dry it before packing it away.

Focus is entirely manual. Static interiors and night skies suit this pace, while moving subjects force you to judge distance and pre-focus by hand. The focusing ring gives direct control over exactly where focus lands.

Inside, the Canon EF version holds 12 elements in 10 groups, one of them a low-dispersion element. Low-dispersion glass helps reduce chromatic aberration, where colours focus at different points and leave coloured fringes along high-contrast edges. That design aim matters for night skies, where bright points sit against dark sky.
