Tilta Khronos Cine Optical Lens Adapter Introduced – Brings PL and E-Mount Lenses to Your iPhone

At NAB 2026, Tilta revealed a working prototype of the Khronos Cine, an optical lens adapter that lets an iPhone shoot through PL or E-mount glass while preserving roughly Alexa Mini LF-class coverage. Pricing is estimated at around $500, with pre-orders targeted for late Q3 2026 and first shipments in early Q4.

Tilta has built out the Khronos ecosystem steadily since the original iPhone 15 Pro system launched in 2024, and the range now covers the iPhone 17 Pro alongside the 16 and 15 Pro generations. At the Tilta booth, we spoke with Nick, Lead Technical Consultant at Tilta Inc., about the most unusual Khronos accessory to date: a rig-scale optical device that turns the phone into a recording back for full-size cinema glass.

A projection adapter, not a camera

The Tilta Khronos Cine looks, at a glance, like a compact cinema body. It sits between the Khronos case and a PL or E-mount lens, with standard rod ports, top-handle mounts, and a battery-plate receiver. It is not, however, a camera. Nick described it as a projection device that takes the image formed by the attached lens and relays it into a format the iPhone’s native rear lens can capture. The phone still records the footage, still leans on Apple Log or ProRes workflows, and still benefits from the rest of the Khronos accessory chain.

Roughly Alexa Mini LF coverage

Nick told us the covered field of view is comparable to that of a full-frame sensor, specifically the Alexa Mini LF. Lenses with enough coverage map onto the phone without severe vignetting, and the operator can either shoot the iPhone’s standard capture area or switch to open gate to pull in additional frame height. There is also room to punch in further if a given lens is a touch soft or does not quite cover the full area.

Depth of field is where the claim becomes more nuanced. Nick was clear that the adapter replicates the feel of a large-sensor image but does not aim to match an Alexa Mini LF exactly. Vintage, anamorphic, or character-heavy lenses will carry their flaws and flares onto the phone in ways the iPhone’s fixed optics cannot replicate on their own. In other words, the effect captures the feel without matching it exactly.

Slotting into the existing Khronos ecosystem

Mechanically, the Khronos Cine uses the same baseplates, top handles, and battery plates as Tilta’s other cage systems. The Khronos phone case, which has always doubled as an everyday case, clips into the back of the adapter, so the phone can be separated and handed off for handheld work without disassembling anything bolted to the tripod.

Forward compatibility is the obvious question for an iPhone-specific accessory. Nick expects the Khronos Cine to follow Tilta’s usual pattern: a new case each Apple generation, and an affordable mechanical adapter or backplate to keep legacy accessories working rather than a fresh unit every year. He also expects the system to extend to the Samsung Galaxy cases Tilta already produces. Both are reasonable bets on Tilta’s past track record, though neither is confirmed.

Who is this actually for?

The Khronos Cine is counterintuitive in one important way: it throws away the main advantage of shooting on a phone, which is size. Nick framed it as an additive option for shoots already using multiple iPhones rather than a replacement for the small, naked-phone setups driving much of the recent smartphone filmmaking work. He cited two-camera over-the-shoulder setups wanting a more intimate, zoomed-in look, productions that want optical zoom and wireless video on top of the phone’s manageable files, and operators stepping up from a phone toward a traditional rig without yet committing to a Sony FX3 or similar.

Price and availability

Tilta currently estimates the Khronos Cine at around $500, with Nick noting the figure could move depending on the final glass design. Pre-orders are targeted for late Q3 2026, with first shipments in early Q4.
