It has a Dual Action Zoom system that includes straight and ring zoom, a dust and splash resistant structure, and customizable switches helping photographers and filmmakers adapt quickly and easily to virtually any shooting environment. Capture the long-reach images you have always wanted with an ultra-telephoto lens—that's the visual experience you will enjoy with the 150-600mm F5-6.3 DG DN OS | Sports, the first ultra-telephoto lens for mirrorless systems from SIGMA Sports line.* Based on CIPA guidelines (measured in 600mm with a 35mm full-size image sensor) [Key features] 1. Uncompromising optical performance throughout the zoom range The SIGMA 150-600mm F5-6.3 DG DN OS | Sports offers outstanding optical performance throughout its zoom range and at all apertures, yielding professional quality results. Based on the latest optical design technology, its lens construction of 25 elements in 15 groups includes a range of special types of high-performance glass that ensures thorough control of different types of aberrations. This helps give images the resolution and clearest detail—not only at the tele end around 600mm, which is critical for an ultra-telephoto zoom, but also throughout its entire zoom range—with no compromise. The lens was designed with image quality in the out-of-focus areas in mind as well, with attractive compression and beautiful bokeh for creating eye-catching images that can only be achieved with a long focal length. Through improvements to the optical and mechanical designs as well as extensive simulated testing, the lens has achieved high resistance to ghosting and flare. This helps ensure sharp and high-contrast images even in strong sunlight or in backlit conditions. At the wide end of 150mm, the lens has an impressive minimum focusing distance of 58 cm. On the L-Mount, the use of two dedicated teleconverters will allow you to shoot with AF up to 1200mm. With these features, this new ultra-telephoto lens is the perfect tool for tackling a broad range of shooting situations, giving you a greater freedom in your choice of composition. 2. Fast, high-precision AF and impressive functionality The 150-600mm F5-6.3 DG DN OS | Sports comes with the pro-level functionality that defines the SIGMA Sports line lens, which is designed for capturing fast-action subjects. With an AF actuator controlled by a stepping motor, the lens combines fast and quiet autofocus with excellent tracking of moving objects. Furthermore, a high-precision magnetic sensor enables highly accurate positioning for fast and high-precision AF. This is particularly impressive on an ultra-telephoto lens where the focus lens has to move a significant distance. The OS function delivers effective image stabilization that offers an advantage of approximately 4 stops*, which is ideal for hand-held shooting at slower shutter speeds. It is possible to change the OS settings using the OS switch and Custom Mode switch to best suit the shooting situation. The lens has a Focus Limiter switch offering three-zone AF modification, which helps to speed up AF performance, and on the L-Mount it is possible to set a custom focusing limit via the SIGMA USB DOCK. The lens also has three AFL buttons to which you can assign various functions on the camera side depending on the model of camera used. This ensures that key settings are able to be customized to suit your shooting style and be accessed easily so that you can adapt quickly to changing conditions. With the fast and high-precision AF, 4 stops* image stabilization, and a wide range of customizable functionality that comes with the SIGMA 150-600mm F5-6.3 DG DN OS | Sports, the creative possibilities are limitless. * Based on CIPA guidelines (measured in 600mm with a 35mm full-size image sensor) 3. Outstanding build quality optimized for ultra-telephoto photography The 150-600mm F5-6.3 DG DN OS | Sports combines the build quality that upholds the SIGMA Sports line standards with excellent operability, taking into account different shooting environments and modes of operation expected with an ultra-telephoto lens. A dust and splash resistant structure that stops water drops or dust from getting into the lens, combined with a water and oil repellent coating applied to the front element, gives you a peace of mind even in a harsh shooting environment. The lens features a Dual Action Zoom, which supports both straight zoom and ring zoom, allowing you to change the angle of view in a quick and intuitive way. In addition, there is also a newly incorporated Zoom Torque switch, with which you can change the resistance of the zoom ring and lock it at the wide end, ensuring ease of zoom operation as well as elimination of zoom creep. On the lens body there is a magnesium tripod socket attachable to an Arca Swiss type clamp. The foot is removable and may be replaced with an optional lens foot (replaceable lens foot type) or mounted on a monopod. The lens body uses parts made of aluminum and TSC (Thermally Stable Composite), where they are most suitable. TSC is a type of polycarbonate with a thermal expansion rate similar to that of aluminum, ensuring the lens behaves consistently at different temperatures. By taking advantage of its design intended exclusively for mirrorless camera systems, the lens is both robust—an attribute essential for the Sports line of lensesーand compact and lightweight. Compared to the SIGMA 150-600mm F5-6.3 DG OS HSM | Sports, which is also a Sports line lens but designed for SLR cameras, the new lens is lighter by 760g and shorter by 26.6mm*. * The 150-600mm F5-6.3 DG DN OS | Sports for L-Mount, compared to the 150-600mm F5-6.3 DG OS HSM | Sports for SIGMA SA-mount.

  2. Press release: SIGMA 35mm F1.4 DG DN The evolution of a classic The 35mm F1.4 Art is reborn Exceptional optical performance Fast and quiet AF in a compact body Professional feature-set Superb optical performance and usability power up the most popular focal length. An "Art F1.4 35mm" reborn for mirrorless and empowered through SIGMA's technology to date. The existing 35mm F1.4 DG HSM | Art was SIGMA’s first GLOBAL VISION lens. Released in 2012, it set the standard for all of SIGMA’s subsequent Art-line lenses, and thanks to its exceptional image quality it is still the 35mm prime lens of choice for many professional photographers. Nine years on, the 35mm F1.4 has been redesigned from the ground up specifically for mirrorless cameras, and is the culmination of much of the optical design expertise and advanced production techniques gained over the past decade of GLOBAL VISION lens development. As with all of SIGMA’s lenses, the 35mm F1.4 DG DN | Art is built entirely at its sole factory in Aizu in Japan, where the standard of craftsmanship is of the highest level. As is true with all SIGMA lenses, class-leading optics are right at the heart of the design concept of this new 35mm F1.4 DG DN | Art. Despite being significantly smaller and lighter than the existing 35mm F1.4, it displays an outstanding level of sharpness right to the edges of the frame at all apertures, as well as exceptionally smooth and attractive bokeh and remarkably well-controlled optical aberrations. Designed exclusively for use with mirrorless cameras, the 35mm F1.4 DG DN | Art is light enough to feel perfectly balanced on a compact mirrorless camera, yet is packed with an array of professional features including ultra-fast AF, a de-clickable and lockable aperture ring and a customizable AFL button. This gives the lens operability and portability without compromise, making it as ideal for professional projects as it is for casual outings, and as well-suited to video as it is stills. SIGMA is delighted to introduce you to the new gold standard in wide-aperture 35mm primes. Key features 1. Exceptional optical performance Central to the design of the 35mm F1.4 DG DN | Art is its sophisticated optical performance, which is consistent with the development of all Art line lenses. The lens incorporates 15 elements in 11 groups. With two Special Low Dispersion (SLD) elements, an Extraordinary Low Dispersion (ELD) element, an ‘F’ Low Dispersion (FLD) element and two aspherical elements, and as well as other high-performance glass, the lens’ advanced optical construction utilizes SIGMA’s state-of-the-art optical design technology, minimizing all types of aberration including axial chromatic aberration, which cannot be corrected in-camera. In spite of having a very wide aperture of F1.4, the lens is able to control sagittal coma flare extremely well even wide open, stopping bright points of light from flaring out near the edges of the frame. This will be particularly appealing to night sky photographers. Owing to its 11 rounded diaphragm blades, the lens displays smooth, round bokeh so that out-of-focus areas are not distracting. This makes the 35mm F1.4 DG DN | Art well-suited to portraits, supported by its ultra-sharp image quality and minimal color bleeding. It also performs very well in backlit conditions thanks to SIGMA's anti-ghosting and anti-flare technology that it has cultivated through countless simulations and real-life testing in our many years of lens development. This keeps shots high contrast and free of excessive flare even when working in difficult light. 2. Fast and quiet AF in a compact body The focusing mechanism in the SIGMA 35mm F1.4 DG DN | Art features a stepping motor. This motor controls a focusing lens group composed of a single, lightweight element, which means AF is responsive and quiet, and is able to keep track of moving objects very effectively. Manual focusing is smooth and precise, but with the right amount of resistance for film-makers. Certainly, this lens has a focus mode switch on the body. The SIGMA 35mm F1.4 DG DN | Art wholly embraces the Art line concept, which is “designed with a focus on sophisticated optical performance”. This—paired with its advanced autofocus performance and the convenience of a compact size—makes for a lens that raises the standards. 3, Professional feature-set On the body of the SIGMA 35mm F1.4 DG DN | Art is an aperture ring that allows aperture to be controlled via the lens, or when set to Auto, using the camera. An aperture lock switch on the lens body allows the aperture ring to be locked in Auto so that it’s not accidentally knocked during shooting. A big plus for film-makers, the aperture ring can be de-clicked, allowing users to seamlessly adjust exposure. Also on the lens barrel is a focus mode switch and an AFL button, which can be customized to a desired function from within the camera menu (depending on the model). The switch is ergonomically positioned to be controlled by the thumb during use. A petal type lens hood is included in the box, which helps reduce flare and offers the lens added protection if dropped. The hood has a lock mechanism that keeps it attached securely to the lens, and its rubberized grip makes it quick and easy to attach and remove. On top of this impressive array of features and elegant exterior, the body of the 35mm F1.4 DG DN | Art offers an exceptional level of durability that helps it withstand long-term professional use as well as individual operating parts that give a good fit to the hand. The dust and splash proof structure provides sealing on buttons and along joins between constituent parts, and there’s a rubber gasket around the mount. There’s also a water and oil repellent coating applied to the front element ensures that photographers can rely on it in any conditions.

  3. Sigma announced a new version of the ultra compact full frame fp L. The new model will be equipped with a 61 Megapixel full frame sensor, hybrid autofocus and true 24p video recording. The camera also fully supports USB Power Delivery. Optionally, a new electronic viewfinder will be available, which can be attached to the side of the camera. There is a microphone connector on the AVF - but we won't find it on the camera itself. On the side we find USB and HDMI ports - the USB port supports pass-throu. Electronic viewfinder has 3.68 million dots and 0.36x magnification - the viewfinder can be rotated. Switching between the camera's main screen and EVF is performed manually. The Sigma FP L is the smallest camera in its class, dimensions are: 113 x 70 x 45mm (4.4 x 2.8 x 1.8 ") and weight 427g (13.2oz) including battery and memory card. The camera is sealed against dust and moisture. Due to its small size, the camera is equipped with electronic shutter which resulted in 1/15 sec flash sync speed. Fp L records video in UHD 4K 30p and can save 12-bit Cinema DNG Raw to external SSD. Depending on which recorder is connected to the camera, it can be saved via HDMI in ProRes RAW or Blackmagic RAW formats. FullHD recording at 120fpf is available though with a crop. The Sigma fp L camera will go on sale in mid-April for $2499 for the body only or $2999 with EVF. The EVF-11 itself will cost $699 - it will be compatible with the original fp.
