Panasonic Lumix G X Vario 12-35mm f/2.8 (II) ASPH. HD Power O.I.S. Lens for MFT (Micro Four Thirds), Black {58}

Panasonic's proven 24-70mm-equivalent standard zoom at constant f/2.8

The 12-35mm f/2.8 II covers the focal range that working photographers reach for most: wide enough for interiors and environmental portraits at 12mm, long enough for tighter framing and moderate compression at 35mm. On any Micro Four Thirds body, that's a 24-70mm equivalent with a constant f/2.8 aperture at every focal length. No aperture creep as you zoom, which matters when you're shooting in mixed or low light and need predictable exposure.

Panasonic built this lens with weather sealing, which pairs directly with the weather-resistant bodies in the GH and G9 lines for shooting in rain or dusty conditions. The Nano Surface Coating keeps flare and ghosting controlled when working against strong backlight. HD Power O.I.S. handles camera shake across the zoom range, a genuine asset when shooting handheld video or slow shutter stills. The 58mm filter thread is a practical size, compatible with a wide range of polarizers and ND filters without the bulk of larger front elements.

For a lens released in 2012, this design has held up. ASPH elements correct the distortion and field curvature that plague cheaper standard zooms, and a zoom lock switch keeps the barrel from creeping in a bag. At f/2.8 with MFT's depth of field characteristics, subject separation is workable for portraits and product work, and the aperture gives you real flexibility in available light.

Who It's For

Documentary and photojournalism shooters get a weather-sealed, constant f/2.8 zoom that covers nearly every situation in a single lens. Video-focused GH-series users benefit from HD Power O.I.S. keeping handheld footage stable through the full 12-35mm range. Travel photographers carrying MFT kits for weight savings get a 24-70mm equivalent without packing multiple primes. Event shooters working in unpredictable indoor light rely on f/2.8 staying fixed at 35mm when backgrounds go dark and there's no time to change glass.

FAQ

What's the 35mm focal length equivalent on MFT bodies?

24-70mm. The 2x crop factor of Micro Four Thirds doubles the focal length, making this a standard zoom that covers wide environmental work through short telephoto framing.

Does the aperture stay at f/2.8 throughout the zoom range?

Yes. This is a constant f/2.8 lens from 12mm to 35mm, which means predictable exposure and consistent subject separation as you zoom.

How effective is the Power O.I.S. for video work?

The HD Power O.I.S. handles camera shake across the zoom range, making it genuinely useful for handheld video and slow shutter stills where stabilization prevents visible blur.

Can you use this lens in wet conditions?

The weather sealing pairs with sealed MFT bodies like the GH and G9 for rain and dusty environments, though the lens itself is sealed against moisture intrusion.

What are the ASPH elements doing in this design?

Aspherical elements correct distortion and field curvature that plague cheaper standard zooms, keeping straight lines clean across the frame.

Is there optical creep when you zoom?

No. The zoom lock switch holds the barrel in place so the lens won't extend in a bag or change length unexpectedly during shooting.

What about flare and ghosting in backlit situations?

The Nano Surface Coating suppresses flare and ghosting when working against strong backlight, keeping contrast punchy in difficult lighting.
