Sigma 45mm f/2.8 DG DN Lens for L Mount


$799.00

Sigma 45mm f/2.8 lens

Designed for full-frame Leica L-mount and Sony FE mirrorless cameras, the fast and versatile Sigma 45mm f/2.8 DG DN Contemporary Lens is a normal-length prime that optimizes size as well as weight while rendering notably smooth bokeh with rounded out-of-focus highlights in both the foreground and background. Coupled with its ability to soften the periphery of blurred images while enhancing the three-dimensional impression of an object, its 9.5″ minimum focusing distance makes it suitable for snapshots to tabletop photos, or any imagery where you wish to make your subject stand out.

Though full-time manual focus is available, this lens is equipped with a stepping motor that enables smooth, high-speed autofocusing that is notably quiet whether utilizing features such as Face/Eye Detection AF or during video shooting. A rounded sevenblade diaphragm contributes to the smooth bokeh, and a lens hood is included, which can protect the front element as well as prevent stray light from causing flare.

50mm is the most common focal length for a “standard lens.” It is considered to be ideal for capturing everyday scenes because it best corresponds to the perspective of the human eye. However, it sometimes feels too long to capture the cityscape naturally. I also think of the 35mm, but it is “too short for a belt, too long for a sleeve tie.” After all, I return to the 50mm worrying about the extra length. When I was asked to test this 45mm F2.8 lens, I was most delighted with the 5mm shortness, putting the optical performance aside. The difference of 5mm sounds small, but it makes a big difference in photography. The additional information brought by the 5mm shortness enhances the depth in images and the slight wideness makes me feel light. The location was Kyoto city. The cherry blossoms were in full bloom and I walked as my mood dictated.

We also recommend the use of a 55mm UV Filter see here
