## S9 needed a lens to match
The Panasonic Lumix S9 is a fashion-forward compact camera, but pairing it with a bulky lens ruins the aesthetic. Panasonic already offers the 18-40mm zoom and 40mm prime, now adding the 20mm to complete the lineup.
## Ultra-wide in a tiny package
The new Lumix S 20mm f/2.5 measures just 69 by 41 millimeters and weighs only 142 grams. Its wide-angle perspective works for walkabout, street, travel, landscapes, cityscapes, and architectural interiors.
## Built tough despite being light
The 20mm features dust, splash, and freeze-resistant construction with a weather-sealed metal mounting plate, not plastic. It matches the 40mm prime's design for consistent handling between the two lenses.
## Controls packed into compact design
Despite its small size, the lens includes an AF/MF focus mode switch, customizable focus ring, and customizable function button. Both black and silver colorways are available.
## Fast aperture opens possibilities
The f/2.5 aperture is fairly fast for a wide-angle, making astrophotography viable. The lens also has a minimum focus distance of just 18 centimeters, ideal for close-range work.
## Video-ready with smart features
The ultra-wide angle works great for vlogging and presenting to camera. The lens suppresses focus breathing for smooth video, and pairs well with the S9's fully articulated screen.
## Pricing and availability
The Lumix S 20mm f/2.5 costs $499 in the US and £429 in the UK. Shipping begins in October and it's already shaping up to be one of the best lenses for the Lumix S9.
## Key takeaway

The Panasonic Lumix S 20mm f/2.5 is a lightweight, weather-sealed wide-angle prime that maintains the S9's sleek proportions while offering versatility for travel, street, landscape, and video work.
