150mm · f/2.8
The Leitz Elmaron 150mm f/2.8 is a simple three-element projection lens known for distinctive soap bubble bokeh and an 'angel's ring' effect. It has almost no coating, leading to washed colors, but offers no vignetting and uniform brightness. Build includes a focusing helicoid with a 54mm or 55mm thread, making adaptation relatively easy. It suits photographers seeking creative, characterful bokeh on a budget, but not for critical sharpness or color fidelity.
