Stopping down eliminates these issues, but also increases depth of field. Looking closely, there’s a very slight hint of mechanical vignetting wide open, as well as slightly overcorrected spherical aberration (hard edged bokeh). The bokeh of the Summicron 28 is excellent for a wide angle lens. Wide angle lenses never have very shallow depth of field, but I’ve found that 28/2 still offers enough separation due to the fairly smooth but still distinct transitions between planes. Global contrast is medium high, with clear definition but retaining detail in both highlights and shadow. Micro-contrast is at extremely impressive levels, achieving tonal separation in even very fine details and between very similar tones. Stopping down increases resolution very slightly for each stop between f/2-f/4. Sharp from corner to corner, even wide open. This is the most impressive lens that I’ve used from an image quality perspective. In practice the image quality is almost perfect. Since I prefer to use my lenses rather than collect them, I don’t mind worn gear. The copy I picked up has been used heavily by two previous owners, which shows through the slightly scuffed up exterior, but the internals are still as new. The black version is more prone to showing scuffing and wear. The black lens is made of anodised aluminum resulting in lower weight than the silver version made of brass. Fairly big and clumsy, made from thick matte plastic.īlack and silver versions of the lens were originally sold, but the silver was discontinued in 2010. The lens hood is not as nice as the lens. Lens markings are engraved and painted in Leicas very pretty, Microgramma-esque, square font. All moveable parts work with impeccable precision. Even compared to other M-mount lenses it’s small to moderately sized, compared to SLR lenses, it’s positively tiny.Ĭonstruction and materials are both top notch – Leica lenses are generally built to last and their modern lenses in particular, are in a league of their own. Earlier Leica 28mm lenses were the same size, despite being a full stop slower. The lens is impressively small considering its specifications, extending just over 4cm from the mount. Leica have become famous for their high level of craftsmanship, as well as the ability to achieve very high optical performance out of very small lenses.
