Tilta has expanded its Khronos mobile ecosystem with a set of four dedicated lenses for iPhone, threading onto the T-Series Lens Mount Adapter to add focal lengths the phone cannot reach natively. The line covers an 8mm fisheye, a 16mm wide-angle, a 10x macro, and a 40mm telephoto, all machined in a champagne-finish aluminum alloy and priced between $69 and $89.
The pitch here is straightforward for anyone already invested in the Khronos platform: rather than swapping to the iPhone’s built-in ultra-wide or digital zoom and accepting the image trade-offs that come with those cameras, you attach optical glass in front of the main sensor and keep working at full quality. Each lens twists and locks onto any T-Series Lens Mount Adapter, and the whole set is compatible with Tilta Khronos cases for the iPhone 15, 16, and 17 series. We have followed the Khronos system closely since it first arrived, from the original iPhone 15 Pro launch through the redesigned iPhone 16 Pro generation and the iPhone 17 Pro generation, and these lenses slot neatly into that growing accessory chain.
A caution on the T-Mount name
Before getting into the individual optics, one point is worth flagging, and it is one we raised in our Khronos field review. The term “T-Mount” has become slippery across the mobile accessory market, with different manufacturers applying it to incompatible mechanical standards. Tilta’s T-Series adapter uses its own locking interface, so these lenses are designed to work within the Khronos ecosystem and other T-Mount compatible cases rather than as a universal solution. If you are buying into the system, source the glass that matches the adapter rather than assuming any lens carrying the “T-Mount” label will lock on.
The 8mm fisheye
The widest and cheapest of the group at $69, the 8mm fisheye delivers a 220-degree field of view with a close minimum focus distance. It produces the strong barrel distortion and perspective warp you would expect, which Tilta positions toward action work, music videos, pet POV shots, creative architecture, and anywhere a conventional angle simply is not enough. It weighs 4.23oz (120g), keeping it manageable on a rigged phone.

At 16mm, this wide-angle lens is aimed at opening up a scene without cropping down to the iPhone’s 0.5x ultra-wide camera and its associated quality trade-offs. Working through the main camera instead, it delivers a wider field of view while maintaining edge-to-edge sharpness, which Tilta suggests suits architecture, landscapes, and group shots. It is the lightest lens in the set at 4.16oz (118g) and carries an $89 price tag.

The 10x macro lens, also $89, is built for close-up detail work, capturing textures in small subjects such as flowers, plants, and insects. Tilta describes the result as crystal-clear rendering with natural background blur for subject isolation, the kind of shallow separation that is hard to coax from a phone’s native optics. At 4.45oz (126.2g), it remains travel-friendly for a lens dedicated to a fairly specialized job.

Rounding out the set, the 40mm telephoto pairs with the iPhone’s main camera to deliver an effective 1.6x reach. Tilta frames this as a more natural perspective, closer to how our own eyes see the world, with added foreground blur and subject-to-background compression. The intended applications are portraits, street photography, and everyday documentation where a slightly longer perspective flatters the subject. It is the heaviest of the four at 5.25oz (148.9g), though still light in absolute terms.

Across the board, the lenses are constructed from lightweight aluminum alloy and glass, and installation is the same twist-and-click action used throughout the Khronos range. That mechanical consistency is one of the more appealing aspects of the system: if you already own the T-Series adapter, adding these focal lengths does not require any new mounting hardware or workflow changes.
The wider context is a mobile lens market that has grown considerably. Tilta is entering territory that established players like Moment and SANDMARC have occupied for years, and it does so while also pushing the more ambitious end of iPhone optics with its Khronos Cine adapter for PL and E-mount cinema glass. These four clip-on lenses sit at the accessible end of that spectrum, offering focal-length variety without the bulk or expense of a full optical adapter.
Pricing and availability
The Tilta T-Mount lenses for iPhone are available now in the champagne finish. The 8mm fisheye is priced at $69, while the 16mm wide-angle, 10x macro, and 40mm telephoto each retail for $89. All four require a compatible T-Series Lens Mount Adapter and a Khronos case for the iPhone 15, 16, or 17 series. Full details are available on Tilta’s website.
