Panasonic - LUMIX Leica DG Summilux 9mm f/1.7 ASPH. Lens for Micro Four Thirds Camera - Black

I bought this to replace a Venus Laowa 7.5mm because I just couldn't get sharp photos from it. The problem was no doubt my eyesight, but the Panasonic has auto-focus and that resolves the problem. I find the slightly reduced angle of view to be acceptable and the Panasonic is a slightly faster lens. When I use it, the focus ring has a very smooth action. I don't mind too much that the body is plastic - that makes the lens a bit lighter. Another point is that it is dust, splash, and freeze-resistant. All said, I am glad I moved up to the Panasonic.

Minimal distortion at the edges. Perfect addition for landscape photography.

This lens is the best wide lens I've ever used for the m4/3 system. It renders well and doesn't distort. In the short time I've had it, it's quickly become a favorite. The one thing I would change would be to have it made of metal. As it is, this lens is high quality and a really great addition to anyone's camera setup.

Although it is pricey, it is worth every penny. Extraordinary wide angle lens for micro 4/3 users. Light, sharp, fast, weather resistant and well made. Pairs well with my Olympus OM-D E-M5 Mark III body. Although it has a polycarbonate body it feels right and this type of lens construction allows for the light weight. Small and light is the hallmark of why most people use micro 4/3 and this lens is a must have for many people using the system.

Panasonic needs to put together a G100 bundle with this lens to save their credibility on that thing's marketing. Give it 30 minute 4K, too. The 12-32 that came on it is too zoomed and slow - especially when you turn on the electronic stab'. 9mm is more like it, and at a vlogging length it gives you a decent amount of Bokeh. Probably just right for giving background context. That being said, f/1.7 really isn't that impressive for Bokeh when you're talking Micro Four Thirds. You're getting f/3.4 Full Frame equivalent. I honestly couldn't tell a difference compared to my 12-35mm f/2.8 unless I stuck the 9mm right up to my face, and that presents the viewer with a fatter-than-real-life version of you. As for focus distance and lack of fish-eye effect, this lens is good. Corners are sharp too. I give this 3 stars because it's a single focal length yet costs close to what other zoom lenses with OIS do. And it's a "plastic fantastic". C'mon, man. Bring that price down 20% and I'll come back. For now, however, I'm going to be returning it.
