"Premium Compact Primes" for mirrorless usersThe Sigma I series features full-frame compatible lenses that offer new value to mirrorless systems. The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot. Sigma is aware that in today's world we have a wide range of camera choices, especially with the increase in mobile phone ownership.But with many people look for something more than a mere act of "taking pictures" when they choose to own a camera and lenses, I series lenses offer the ultimate combination of superb optical performance, outstanding usability and compact form-factor. Sigma's excellence in development and production technologies has been built up since our founding in 1961 and became increasingly sophisticated with the introduction of the Sigma Global Vision brand in 2012. With this as a base, Sigma has given careful thought to the quality of the products, the feeling of using it and the pleasure of owning it. This is how the I series was born.Beautiful bokeh and rendering that can be enjoyed in every sceneWith the Sigma 45mm F2.8 DG | Contemporary, bokeh expressions are especially featured. Spherical aberration has been controlled to ensure not only the large bokeh in the front and rear of the subject but also the rear bokeh near the area in focus create a gradient to a soft blur. This lens softens the periphery of blurred images suppressing the double-line bokeh etc. and enhances the three-dimensional impression of the subject with the smooth expressions in the foreground and the background.In addition, its minimum focusing distance of 24cm makes it possible to enjoy shooting snapshots and tabletop photos taking advantage of the angle of view. The design gives consideration to vignetting to achieve beautiful round bokeh and subdue swirly bokeh in the whole bokeh effects.While this lens produces smooth bokeh effects which one could define as "classical expression" when the aperture is wide open, it also realizes modern sharp rendering when it is stopped down. It is reassuring to hold this lens as a regular lens for everyday use.High build quality and outstanding operabilityBecause this lens is intended for everyday use, particular attention has been given to build quality and operability. The lens barrel incorporating metal material as the main part achieves improved durability. Furthermore, thanks to the aperture ring with the right click feeling, comfortable operability during various shooting styles is ensured. The design gives consideration to MF operations, and a ring of appropriate torque provides good operability.Metal bayonet hoodThe lens hood features aluminum, using the same material as the lens body which has realized high quality and high rigidity. Furthermore, the knurling process featured on the surface provides superior usability.High-speed and highly accurate AF enabled by the stepping motorThe lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, which also supports Face/Eye Detection AF and video AF.TechnologyInner focus systemTo increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
