Panasonic is launching the 18-40mm F4.5-6.3 lens that it teased with the launch of the Lumix S9 earlier this year. It claims the new lens is the smallest and lightest interchangeable zoom with autofocus for full-frame mirrorless cameras. While that's quite a few caveats, it is undoubtedly compact: the lens weighs 155g (5.5oz) and is 40.9mm (1.6") long when retracted.

Despite being an extending lens, Panasonic claims it's dust, splash, and freeze resistant and can be used in temperatures down to -10°C (14°F). The front element also has a fluorine coating for dirt and oil resistance.

While the lens is far from being a macro – it offers a maximum magnification of 0.28x at 21mm – it still has relatively close-focusing abilities and can focus on a subject at 15cm (5.9") in its 18-21mm focal range. Fully zoomed in, its closest focusing distance goes up to 35cm (13.8").

The 18-40mm is made up of 8 elements in 7 groups and features 3 aspherical elements, 2 ED elements and a UHR element. It accepts 62mm filters.

Panasonic is making this lens the new kit lens for the S9. The creator-focused camera originally launched with the company's 20-60mm f3.5-5.6 as the kit lens, which has greater reach and brighter max aperture at the cost of being double the weight of the 18-40mm. Given the S9's focus on being a small, portable full-frame camera, it seems likely the trade-off will be worth it for at least some of the audience Panasonic is targeting with the S9.

S9 users take note: while the lens may have some level of weather sealing, the camera itself does not.

The company is also announcing two new colors of the S9: a mint green and 'sakura' pink model will be available in the US, in addition to the existing black, blue, olive, and red models.

On its own, the lens will be $499, and the S9 kit that includes it will cost $1,799, the same as the 20-60mm kit. That may make the kit a slightly worse value, depending on how you look at it; purchased by itself, the 20-60mm costs $100 more than the 18-40mm.

Panasonic has also announced new software updates that bring some substantial changes to the S9; you can read our coverage of them here.
