KIPON RF Colibri 35mm T2.5 Full-Frame Cine Review

A $1150 manual cine prime for Canon RF. Its T2.5 aperture and optical scores are mediocre, but it's built like a tank (77th percentile) for rig use. Only consider if you want the Colibri series' consistent 80mm front diameter and cine gears for a matched set.

The KIPON Colibri 35mm T2.5 is a niche lens that knows its audience. It's a compact, manual focus cine lens designed for Canon RF shooters who want a consistent look across a set. At $1150, it's priced like a specialty tool, not a general-purpose prime. Its overall score of 37.5 out of 100 in our database tells you it's not trying to be everything, but its 77th percentile build quality suggests it's built for the rigors of a cage and follow focus.

Performance here is about the features, not the specs. The T2.5 aperture lands in the 29th percentile, so it's not a low-light monster. Optical quality sits at the 35th percentile, meaning it's sharp enough for video but don't expect photography-grade perfection. Where it shines is in its cine-specific design: the 300-degree focus rotation and 0.8 MOD gears give you precise manual control, and the 10-blade iris creates that unique star-shaped bokeh. It's a lens built for pulling focus, not for chasing it.

At $1150, the value proposition is very specific. You're paying for the cine-ready build, the consistent design language with other Colibri lenses, and that unique bokeh character. It's not a value leader in terms of pure optical specs—you can get faster, sharper autofocus lenses for less. The value is in the workflow. If you're building out a matched set of manual cine primes for your RF camera, the price makes sense. If you're a solo shooter who needs autofocus, it's a tough sell.

Compared to the Viltrox 35mm F1.7, you're giving up over two stops of light (F1.7 vs T2.5) and autofocus for the Colibri's manual cine features. The Viltrox is a stills/video hybrid; the Colibri is a dedicated video tool. Against the Nikon NIKKOR Z 35mm f/1.8 S, the Nikon destroys it in optical performance and autofocus but lacks the geared focus ring and common front diameter for a lens set. The Meike 55mm F1.8 Pro is another hybrid, offering AF and a brighter aperture but in a different focal length. The Colibri only wins if your priority is a manual cine lens ecosystem.

Skip this lens if you need autofocus, shoot in low light without controlled lighting, or prioritize optical sharpness above all else. Its scores in aperture (29th percentile), optical performance (35th), and AF (45th) are all weak compared to hybrid photo/video lenses. It's also a poor choice for landscape work, which is its weakest category at 30.2 out of 100. If you're not committed to a manual cine lens ecosystem, your money is better spent elsewhere.

We can only recommend the KIPON Colibri 35mm T2.5 if you're deep into manual filmmaking with a Canon RF camera and plan to buy into the Colibri series for its consistent handling. Its middling optical and aperture scores mean it's a compromise as a standalone lens. But for that specific user—someone who values the 300-degree focus throw, the 0.8 MOD gears, and the ability to swap lenses without changing matte boxes or follow focus setups—it's a competent, well-built option. For everyone else, a faster, autofocus hybrid lens will be more versatile and likely cheaper.
