Tilta Khronos 17mm Thread Lens Adapter for iPhone 17 Pro - Space Gray

The Khronos 17mm Thread Lens Adapter for iPhone 17 Pro (Space Gray) 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: 17mm thread — the screw-in standard for phone lenses. The case and the lens are not included.

Khronos 17mm Thread Lens Adapter for iPhone 17 Pro — Space Gray.

The part slides into the dedicated slot of the Tilta Khronos or Khronos Lite case for iPhone 17 Pro and clicks into place. A safety buckle keeps it from sliding out while shooting; press the PRESS buckle and pull to remove it. The aluminium alloy construction adds almost no bulk to the case.

17mm screw thread

Instead of a bayonet this adapter carries a 17mm thread — the most widespread screw-in standard for phone lenses. The lens simply screws in. It is the most open of the four systems: any 17mm-thread add-on lens fits, not just one brand.

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 and a lens with a 17mm thread; neither is included. Tilta’s own T-Mount lenses (8mm, 16mm, 40mm, 10x macro) do not fit this adapter — those belong on the T-Mount adapter.

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.
