Designed for Micro Four Thirds mirrorless cameras, this lens provides a 50mm equivalent focal length to represent a normal perspective.
Fast f/1.7 maximum aperture benefits working in difficult lighting conditions and also enables extensive control over focus placement for selective focus applications.
One UHR element and a pair of aspherical elements help to achieve even illumination and sharpness for consistent performance throughout the aperture range.
A Nano Surface Coating has been applied to individual elements to noticeably reduce lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.
Stepping motor delivers fast, smooth, and near-silent autofocus performance to benefit both still photograph and movie recording applications.
Rounded seven-blade diaphragm produces a smooth out-of-focus quality when working with shallow depth of field techniques.

Needed a replacement for my Sigma 19mm and this fits the bill. Quick, sharp focus and stopping down to 2.8 everything is sharp uacross the frame. Not worried about low light. Used it for landscape and street with no problems. Thanks Panasonic.

The Pany 25mm lens is a size that I didn't have and when the great sale price came along, I jumped on it. The lens is sharp and B+H gpt it to me in just a few days. Good work folks.

Works as expected.

I'm a beginner, using my Panasonic camera for videos. This lens has been an inexpensive option that has done exactly what I'd hoped. I had some trouble getting the hood attached to the end of the lens. Other than that, it's been great (though I have little to compare it to).

Good little lens for the price.

Reliable and cheap lens for beginners. Autofocus is crisp and seems to work well with the Lumix G7.

Great for interviews and overall portrait like setups

Using it in my Zcam rig for interviews. It works as a charm. Great picture quality. The 25mm gets perfect for my workload.

Images comes out great! But...

I use this lens with the Black Magic Pocket CC 4K. If I leave the lens on and turn on the camera, everything works great. But if I change the camera setting (like switching from 4K to HD), the lens will start to make clicking sound (and the electronic iris will not work. As in the option to change the iris just disappear.) I usually solve this by twisting the lens tighter. Or just shut off the camera, take out the lens and then putting it back on, then turn the camera on. Other than that, images looks great!

Really solid medium lens.
