Tilta Khronos K Series Mount Lens Adapter for iPhone 17 Pro Max - Black

The Khronos K Series Lens Adapter for iPhone 17 Pro Max (Black) adds a phone-lens mount to the Tilta Khronos or Khronos Lite case. It slides into the dedicated slot of the case and locks with a safety buckle; press the PRESS buckle to release it. Mount: K Series — bayonet for phone lenses with a K Series mount. The case and the lens are not included.

The part slides into the dedicated slot of the Tilta Khronos or Khronos Lite case for iPhone 17 Pro Max and clicks into place. A safety buckle keeps it from sliding out while shooting; press the PRESS buckle and pull to remove it.

Lenses with a K Series mount

The adapter is a bayonet for phone lenses with a K Series mount. Lenses with a T-Mount or a 17mm thread do not fit it — Tilta makes separate adapters for those, for the same case slot.

What you need with it

The adapter is a link in the chain. You also need a Khronos or Khronos Lite case for iPhone 17 Pro Max and a lens with a K Series mount; neither is included.

Four mounting systems — and how they differ

The Tilta Khronos and Khronos Lite cases for iPhone 17 Pro and Pro Max have one dedicated slot above the camera. One part slides in, locks with a safety buckle and releases by pressing the PRESS buckle. Tilta offers four different parts for that slot and they are not interchangeable:

• T-Mount adapter — a bayonet for lenses with the Fotogear T-Series mount; the included spacer adds compatibility with Moment T-Series lenses. This is where the Tilta 8mm, 16mm, 40mm and 10x macro lenses go.
• K Series adapter — a bayonet for lenses with the K Series mount. T-Mount lenses do not fit it.
• 17mm thread adapter — the most widespread screw-in standard for phone lenses; the lens screws into the adapter.
• Filter tray — holds a filter, not a lens. The 58mm version takes Tilta 58mm circular magnetic filters, the quick release version takes Khronos magnetic filters (FSND, Black Mist, White Mist).

The parts are also tied to the phone model: a part for iPhone 17 Pro does not fit the iPhone 17 Pro Max and vice versa.

The Tilta Khronos ecosystem

Khronos is a modular system for shooting with a phone: a case or cage with mounting points that take magnetic filters, cooling, handles, lights, a USB-C hub and brackets via quick release. The parts combine and carry over between phone generations — this one is among them.
