Laowa 4mm f2.8 Circular Fisheye for Micro Four Thirds lens mount_Bronica ETR 40mm is a really niceThe Laowa 4mm f2. 8 Circular Fisheye is a very small fisheye lens that provides an angle of view of 210 degrees, which is a lot of degrees. The image is circular, which means that it does not fill up the MFT frame: it's a round projection in the centre of the frame. Manual focus, but everything is pretty much in focus anyway. In excellent condition, with original box.
