Distinguished by its remarkably circular bokeh, the Leica M-mount 100mm f/2.8 Lens from TTArtisan is a full-frame telephoto lens that naturally creates images that stand out. 13 aperture blades contribute to producing the smooth "soap bubble bokeh" that this lens is known for. The combination of a 100mm focal length and a distinctive bokeh effect makes this a strong choice for capturing nature as well as portraits.
