Panasonic Leica DG Vario-Elmarit H-ES12060 12-60mm

The Panasonic Leica 12-60mm f/2.8-4 is a sharp, weather-sealed zoom with autofocus that's among the best we've tested. The f/2.8 aperture only applies at 12mm, which is the main catch. If you shoot Micro Four Thirds and want one lens for almost everything, this is a great buy.

Autofocus is where this lens flexes hardest. The linear motor snaps into focus fast and quietly, landing in the 98th percentile in our database. That's best-in-class territory, and it shows whether you're tracking a moving subject or pulling focus in video. Optically it's a standout too, with four aspherical elements and two ED elements keeping things sharp and free of fringing. The 9-blade diaphragm gives you decent bokeh for a zoom, though it's not going to melt backgrounds like a fast prime. Stabilization is strong but not class-leading, and macro performance is just okay at 0.3x magnification. The real limitation is the variable aperture. f/2.8 at 12mm is nice, but by 60mm you're at f/4, and that's a noticeable drop when the light gets dim.

Stacked against the Sigma 18-50mm f/2.8 DC DN, the Panasonic gives you more reach and weather sealing, but the Sigma holds f/2.8 across its entire range. That's a real trade-off if you shoot in low light a lot. The Sony E 18-135mm f/3.5-5.6 OSS offers more telephoto reach but slower apertures and no weather sealing. The Nikon Z 17-28mm f/2.8 is faster and wider but covers a much narrower range. For Micro Four Thirds shooters who want one lens that does almost everything, the Panasonic is hard to beat. The Tamron 28-300mm is a different beast entirely, more of a superzoom for full-frame, and it's slower and bulkier.

At $848 to $898 USD, this lens isn't cheap, but it's not outrageous either. You're paying for the Leica badge, the weather sealing, and autofocus that embarrasses lenses costing twice as much. Owners consistently call it a great value, especially if you grab it as a kit lens or find it bundled. The build quality alone makes it feel like money well spent. If you're on a tight budget, there are cheaper zooms, but you'll give up the speed, the sealing, or both.

The Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4 is the lens that should probably live on your Micro Four Thirds camera. It covers a 24-120mm equivalent range, which handles everything from wide street scenes to casual portraits without a lens swap. At 320g it's light enough to carry all day, and the weather sealing means you don't have to baby it when the sky turns ugly.

Our database puts this thing near the top for autofocus and versatility, and owners agree. The sharpness is real, the build feels premium, and the stabilization actually works. The catch? That f/2.8 aperture only exists at 12mm. Zoom in and you're at f/4 before you know it, which stings in low light.

Skip this if you shoot a lot in low light at longer focal lengths. The f/4 maximum aperture at 60mm will frustrate you, and you'd be better off with a constant f/2.8 zoom or a fast prime. Macro shooters should also look elsewhere, since the 0.3x magnification is nothing special. If you need serious telephoto reach, this isn't your lens either.

This is the lens for Micro Four Thirds shooters who want one do-it-all zoom that's sharp, fast to focus, and built to survive real weather. Street photographers and videographers will love it. The variable aperture is the main compromise, and if you shoot a lot in dim conditions at longer focal lengths, you'll feel it. But for everyday carry, travel, and general photography, this is one of the best zooms you can put on an MFT body.
