For its price (I got it for $147.99) it's amazing. I know there are better lenses around within the same focal length and aperture range, but they would be at least x3 more expensive. No way they are 3 times better. It's sharp, fast, with beautiful bokeh. I would buy it again for this price.

Incredibly affordable f/1.7 lens that is easily the best value in 25mm primes around. I purchased this on sale for a comically-low price to replace the good-but-slower Sigma 19mm and 20mm primes in my stable.

f/1.7; Thank you; Fast; Included hood; Low Price; Smooth focus ring

All-Plastic build; No pouch; Slow to focus in some situations

Having long since promised myself I'd get a fast prime (with autofocus) after a few years of using a converted Canon FD lens, I was torn between the 25mm f1.7 and the Leica f1.4. I decided that discretion is the better part of my wallet and went with the f1.7 and I have to say it was a great choice.

I have the LUMIX G7 and have been using my 12-60mm kit lens since I got it. I ordered this prime lens as it was highly rated, highly reviewed and I needed a prime for it. I was not disappointed. After just an hour or so of use, you really can see the quality of this lens shine.

Pictures are sharp and no more focus hunting.... Working toward movie production and willing to take the extra time learning manual settings to shoot like the pro's. The extra low light capability is another big reason for this lens...

A no-brainer choice. Micro four thirds users will have to look far and wide to find anything that scores so well overall at current prices. OK, the 20mm f1.7 is smaller for those who want pocket-size, pancake glass, but for the rest of us this 25mm earns its keep everytime.

This is a great prime lens for those who don\'t want to spend hugely to gain quality results. Metal mount, smooth manual focusing ring, lightweight and easy to handle. This \'nifty-fifty\' equivalent adds another dimension to your photography; f1.7 to f4 gives stand out results, with f5.6 the real...

Annoying decorative lens ring which needs to be removed before fitting the lens hood provided; Diffraction becomes obvious beyond f11

Andy Westlake puts an inexpensive fast normal prime lens for Micro Four Thirds cameras to the test.

The Panasonic Lumix G 25mm f/1.7 for Micro Four Thirds is the equivalent of the 50mm f/1.8 or f/1.7 lenses that for decades were considered the standard lenses for 35mm film cameras. Typically these were high quality optics, made in vast numbers so at relatively low cost.

High levels of sharpness; Low distortion; Low CA; Close focusing; Well made

No weather resistance; Flare levels high against the light

The Panasonic Lumix G 25mm f/1.7 ASPH is a very good standard lens at a very affordable price, making it a must-have purchase if you don't already have a 50mm equivalent lens in your kit-bag. Optically the Panasonic Lumix G 25mm f/1.7 ASPH is an excellent performer.

Let's first take a look at the alternatives that are already available. Panasonic itself makes the compact Lumix G 20mm f/1.7 II Asph and the faster Leica Summilux DG 25mm f/1.4, but they cost ￡270 and ￡380 respectively.
