Laowa 4mm 2.8 Fisheye für Micro-Four-Thirds

The Laowa 4mm f/2.8 circular fisheye is both difficult as well as fun to use. Due to its immense image field, it will create lots of frustration because very often it's just too much really and staying out of the image is actually not as trivial as you might think. Conversely, if you find the right subject, the results are very rewarding indeed. It's also just awesome to explore this strange new extreme fisheye world. The image quality is almost secondary but technically it is still surprisingly high. The center quality is great and the image borders are pretty nice when stopped down a little. Chromatic aberrations are fairly high but that's rather typical for most lenses in this class. As mentioned there's also a zone with heavy fringing albeit you would/SHOULD apply a circular crop anyway. If this is no option for you, it's best to stay away. Flare and also glare can be an issue in difficut lighting. In terms of mechanical quality, Laowa did a good job. Thus the lens body is made of metal down to the mount. This also applies to the lens "cap" - a tube really. There is no electronic coupling, thus you'll have to live without EXIF data as well as a manually controlled aperture and focus. Focusing is rarely an issue though. Unless you try your luck with closeups, most of the world will be in focus anyway - just set it to 1m and you are good to go. So do you have to own a lens like the Laowa 4mm f/2.8 Circular Fisheye? No. But you should and at just 199USD, it is a steal really. Highly recommended!
