It’s been a while since we’ve seen a new lens from Swiss lens company, Irix. In fact, while they’ve been adding a lot to their Edge filter system, we haven’t seen a new lens since Photokina 2016 when they showed off the 45mm f/1.4 – a lens that still doesn’t exist.

But it looks like they’re teasing a new one for an announcement at Photokina 2018, though. At least, that’s what these three short videos suggest. All we really know is that it’s called “Dragonfly”, but it might be a 150mm macro lens.

The Dragonfly Telescope Uses Ten Canon 400mm f/2.8 Lenses to Detect Faint Galaxies

While telescopes do a great job gathering light and obtaining images of ridiculously distant objects, even the largest and most advanced units are assumed to be unable to detect certain faint structures due scattered light which may be hiding them.

An awkward looking, multi-lens array was built to solve the problem – the Dragonfly Telephoto Array. Using ten of Canon’s finest 400mm lenses, the Dragonfly’s design significantly reduces scattered light and internal reflections within the optics, allowing ultra-low surface brightness astronomy at visible wavelengths.
