A classic wide angle lens updated for full-frame Sony E-mount mirrorless systemsthe 35mm f/1.4 DG DN from Sigma is an Art-series prime characterized by its advanced and updated optical designsleek profileand bright design. The f/1.4 maximum aperture enables working in low-light conditions and also provides increased control over depth of field for achieving shallow depth of field effects. The optical layout incorporates two SLD Special-Low Dispersionone ELD Extra-Low Dispersionand one FLD Low Dispersion elements. It also incorporates two aspherical elements and high refractive index elements to achieve a notable degree of clarity and sharpness with well-controlled distortion and aberrations. Alsoa Super Multi-Layer Coating enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions.
Balancing the optics is a refined exterior designwhich features a physical aperture ringwhich can be de-clicked or lockedalong with a dedicated focus mode switch and AFL button for intuitive and tactile control. For autofocusa stepping motor is used that maintains a lightweight and compact design while promoting fast and near silent focusing performance for both stills and video applications. Additionallythe lens features an 11-blade rounded diaphragm for smooth bokeh quality and the lens housing is also weather-sealed to suit working in inclement conditions.
- As part of the Art line within Sigma's Global Vision seriesthis lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
- Wide-angle lens is designed for full-frame Sony E-mount mirrorless cameras but can also be used with APS-C models where it provides a 52.5mm equivalent focal length.
- Bright f/1.4 maximum aperture is particularly well-suited for working in available light conditions and provides extensive control over depth of field for isolating subject matter with selective focus.
- Lens Construction: 15 elements in 11 groupsincluding one FLD low-dispersion elementone ELD extra-low dispersion elementtwo SLD special-low dispersion elementsand two aspherical elements.
- A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imageryeven in backlit conditions. Resistance coating allows oil and water to be easily wiped from the front lens surface and prevents oil and fat from sticking for easy cleaning.
- Integrated stepping motor realizes quick and quiet internal autofocuswhich is further complemented by an optimized AF algorithm to produce smoother focusing performance. Face and eye detection supported in feature enabled cameras.
- Manual aperture ring can be de-clicked for smoothsilent aperture switching to benefit video applications. Additionallya dedicated aperture ring lock switch can also be employed to prevent accidental shifting of the aperture setting.
- Built-in Autofocus-Lock (AFL) button which can be assigned additional functions widens the range of operations available on the lens.
- Rounded eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality.
- Weather-resistant construction with a brass bayonet that affords improved mounting accuracy and rigidity.
