6mm · f/2
The Meike 6.5mm f/2.0 Fisheye is a compact, lightweight manual-focus lens offering a 190° field of view and f/2 aperture, providing good value for money. Optical strengths include sharp images and smooth bokeh, though the bulbous front element is vulnerable without a hood. It suits APS-C and MFT formats, producing a circular image; on MFT the circle is cropped. Weaknesses include a push-on cap that may be easily lost. Best for creative, wide-angle shots where extreme distortion is desired.
