fisheye compensation in camera
Fisheye lenses are very special lenses, which are suitable for taken 360° panoramas for example. However as they have a very large distortion and field of view those lenses are not suitable for many other applications. With software such distortion can be corrected. The OM-D E-M1 series has this correction already built-in to the camera firmware. The advantage is that you can already see the effect before you take the image, which helps you to compose your image. This technology makes the 8mm F1.8 a very wide angle lens which is unique in the market.
