Tilta Khronos Magnetic 58mm Filter Tray Holder for Universal Smartphone Case - Space Gray

The Tilta Khronos Magnetic 58 mm Filter Tray Holder brings tool-free filtration to the Khronos Universal Smartphone Case cage. It aligns across three independent axes — 0–15 mm side to side, 0–42 mm up and down and 2–10 mm front to back — so the filter sits exactly over the lens on any phone.

The holder clamps straight onto the cage and has a single job: to get the filter exactly in front of the lens. Because every phone carries its camera module in a different place and at a different height, the holder adjusts across three axes; once aligned, filters change magnetically, which takes an instant.

Alignment on three axes

The holder clamps straight onto the Khronos Universal Smartphone Case cage and adjusts across three independent axes: 0–15 mm side to side for centering, 0–42 mm up and down for the position of the camera module and 2–10 mm front to back for lens protrusion. Every phone has its lens somewhere else, and yet the filter sits flat and exactly over it. The lightweight aluminum alloy construction adds only minimal weight to the rig.

Magnetic filter changes

Once the holder is aligned, filters change magnetically: a 58 mm Tilta magnetic filter — such as the 1–5 stop variable ND — snaps in with one move and comes off just as fast when you want to shoot without a filter. Through the Khronos 62 mm threaded filter tray, standard screw-on filters go onto this holder too. The filter is not included.

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.
