China Lucky Film appears to have launched a new ISO 100 E6 colour slide film, initially in 4×5 and 8×10 sheet formats – making it the company’s second new colour emulsion of 2026 and a genuinely surprising addition to the shrinking world of transparency film.

The news was first reported by Kosmo Foto, which spotted packaging shared on Reddit’s analogue community, originally published on WeChat. Boxes have been shown in both 4×5 and 8×10, and for now it looks as though the film is available only in large format.

What we know so far

The film is rated at ISO 100 and is processed in standard E6 chemistry, so any lab or home developer already running slide film should be able to handle it. Kosmo Foto reports that it carries a FuLeKangSong label and is described as a cheaper domestic version. Reported prices are 250 RMB (around US$37.50) for a 10-sheet box and 900 RMB (around US$135) for an 8×10 box. There’s no word yet on availability outside China, or on 35mm and 120 versions.

This follows Lucky’s C400 colour negative film, announced at Photo & Imaging Shanghai 2026 and released over the summer, and the C200 that arrived in November 2025. Lucky has clearly been investing in colour coating, and a slide film is a big step – E6 emulsions are notoriously hard to make well.

Why it matters for large format shooters

For anyone shooting a large format camera, the choice of colour transparency film has been painfully narrow for years, and prices have climbed steadily. Here at the college, where we run sheet film through a Sinar, we know how few options students have once they want to try colour on a view camera. A new, potentially cheaper E6 sheet film – if it reaches the UK at a sensible price – could open that up again.

There’s nothing quite like the experience of seeing a 4×5 or 8×10 transparency on a lightbox for the first time. We’ll be watching closely to see whether this film makes its way to European retailers, and how it compares with Ektachrome E100.
