Don't let the weather stop you in your tracks. With IP53-certified weather sealing, the camera is safeguarded against dust, rain, and the cold, so you can snap your adventures in any conditions.

Quickly charge on the go with USB-C. Connect a power bank to keep your camera powered up, ensuring you're ready for every moment, wherever your journey takes you.

Capture ultra-detailed 50–80MP images with HighRes Shot—even handheld. Perfect for wide mountain vistas, forest textures, and all the natural details.
Create smooth motion effects in waterfalls, rivers, or skies—even in broad daylight—without physical filters. Live ND (ND2–16) makes long-exposure shots spontaneous and effortless.
Perfect your macro and landscape shots. In-camera Focus Stacking merges different focus points into one image with a greater depth of field—spot on for flowers, bugs, and landscapes.
Capture scenes with extreme contrast—from sunlit peaks to deep forest shadows—with rich detail in both shadows and highlights using in-camera HDR.
Combine scenes and create artistic blends directly in-camera. Experiment with light, shadow, and texture on your bushwalks and explorations.

With 121 cross-type AF points and phase detection, the camera quickly locks onto subjects, delivering sharp, precise focus—even for fast-moving scenes on land or in the sky.
Wildlife moves quicker than we can react—so should your camera. Pro Capture buffers images before the shutter is fully pressed, so you never miss the perfect moment in uncompromised RAW quality.
Capture fast action in complete silence with 10fps (C-AF) or 30fps (S-AF) sequential shooting—perfect for wildlife, sports, or any moment where silence is golden.

Paint the night with stars, lightning, or light trails. Live Composite stacks only new light, letting you watch your masterpiece come together in real time—without overexposure.
A skill that takes years to master, now behind one button. Starry Sky AF locks sharp focus on stars, so you can snap brilliant astro shots with ease.
Preserve your night vision during moonlit walks or stargazing with a live view that stays visible in low light, allowing for stealthy shooting without disrupting your vision.

Capture stunning 4K footage at 30P for crisp, detailed video of your adventures, or slow down the action with Full HD 120P for smooth, cinematic moments in the bush.
Capture vertical video for easy sharing on social media—perfect for showing off your outdoor moments and discoveries in a format made for your followers.
