Sigma 35mm f1.4 DG DN Art lens for Lumix L-mount 

The 35mm F1.4 DG DN combines excellent image quality, a fast aperture, rapid autofocus and a highly versatile focal length to make it a great choice for a wide range of photography applications, including portraits, landscapes, street, weddings and travel.

The maximum aperture of F1.4 allows photographers to shoot with a very shallow depth-of-field, which helps create subject separation for high impact results.

• Super Multi-Layer and Resistance Coating
• SLD, ELD, FLD , and Aspherical Elements
• Minimum Focus Distance: 30cm
• Stepping Motor AF System
• Customizable AFL Button
• Physical Aperture Ring; De-Click Switch
• Rounded 11-Blade Diaphragm
• Weather-Sealed Design

Thanks to its advanced optical design that includes 15 elements in 11 groups, including one F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements, image quality is exceptionally high, with pin-sharp results free of chromatic aberration at all aperture settings. The lens also has a Super Multi-Layer Coating to reduce ghosting and flare.

The lens has an aperture ring allowing users to change aperture with the lens rather than the camera if desired. This can be de-clicked and locked.

Ideal for landscapes

At F1.4, the lens is able to collect four times more light than an F2.8 optic, making it perfect for low-light photography such as astro and other night-scapes. The lens can render exceptional star detail even in shorter exposures, and saggital coma flare is very minimal meaning that stars remain as sharp, bright points of light even in the corners.

The front and rear filter options make it easy to attach soft filters and light pollution filters.

Professional feature-set

A range of controls on the lens include an AF/MF switch, and a customisable AFL button (depending on camera model).

The lens also has a click/de-click switch so that the aperture ring can be adjusted smoothly rather than in hard stops, which may be useful for film-makers. There’s also a lock switch that keeps the aperture ring in either Auto or Manual. This stops the ring accidentally being knocked out of Auto to F16 during use.

A powerful stepping motor ensure fast, accurate and quiet AF and excellent AF tracking capability.

Outstanding build quality

The exceptional build quality of the 35mm F1.4 DG DN is exactly as you’d expect from an Art-line lens, in the materials used, the overall ergonomics and the quality of craftsmanship.

The exterior barrel is made of a polycarbonate called Thermally Stable Composite (TSC). Not only is this very strong and light, but it has a similar thermal expansion rate to aluminium. This ensures that the interior aluminium parts and the exterior TSC parts behave in a uniform way as temperatures change.

The focus ring is rubberised for easier operation, and focusing is internal, meaning the lens never changes length. This makes it ideal for use on a gimbal as the centre of gravity remains fairly constant.

Towards the rear of the barrel is an aperture ring so that aperture can be changed on the lens, and it has an Auto setting should users prefer to change aperture using the camera.

To reduce flare and ghosting in bright sun, and to help protect the front element from damage if dropped, the lens has a robust petal-type lens hood with lock button. A rubberised ring on the hood makes for easier removal and fitting.

The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
