This is a neat little MFT lens. It's very sharp and very wide (as you'd expect from a fisheye). It's easy to use and my E-M1 II even allows me to save a custom profile for lenses that don't communicate with the camera, which means the IBIS can be adjusted and the EXIF will be contained in the image file. Very happy with this little lens. It reminds me somewhat of my old FD Canon lenses with its construction and manual lens aperture.
I have had a long time idea of taking a few shots by Fisheye lens. When I got my copy, I was pleasantly surprised by the quality and condition of the preservation (since I bought a used one). I took far more shots than I planned and the results are above expected!
