SIGMA Art 17 40 mm f/1.8 DC Standard Zoom Lens for L Mount, Black

Sigma Photo Siaq228 Camera Lens. This bright zoom for APS-C mirrorless cameras offers prime lens performance. With a constant F1.8 aperture, linear focus motor, internal zoom, and a compact, robust body, it´s a powerful tool for both photo and video.A New Standard for Photo and Video:- With prime lens performance, this F1.8 zoom for APS-C mirrorless cameras delivers exceptional image quality across its focal range.ART 17-40mm F1.8 DC:- Inheriting the revolutionary innovations of the acclaimed Sigma 18-35mm F1.8 DC HSM | Art, the industry´s first F1.8 zoom, the Sigma 17-40mm F1.8 DC | Art offers superior optical performance thirteen years later. It achieves this with a wider focal range and a significantly lower weight, features that enhance the versatility of this large-aperture standard zoom.In addition to fast and quiet autofocus thanks to the HLA (High-response Linear Actuator) motor, this lens incorporates an internal zoom mechanism and offers minimal focus breathing, ensuring excellent performance for both photo and video.Sigma, which already surprised the world with the first F1.8 zoom, once again sets a milestone in the history of bright lenses with this new offering for APS-C mirrorless cameras.DC Lenses:- SIGM´s catalog of optics for APS-C or similar size mirrorless cameras (DC) is constantly growing. These lenses are designed to achieve maximum performance on mirrorless bodies.A Large-Aperture Standard Zoom with Prime Lens Quality:- The Sigma 17-40mm F1.8 DC | Art maintains a constant F1.8 aperture throughout the zoom range, making it ideal for low-light scenes such as interiors or night shots, and for achieving pronounced bokeh effects.Excellent Optical Performance:- Thanks to its advanced optical design, which includes high-precision aspherical elements, this lens achieves exceptional resolution even when shooting at F1.8. Effective correction of axial chromatic aberrations and sagittal coma allows for capturing subtle textures and details with surprising sharpness.Its focal range is wider than that of the Sigma 18-35mm F1.8 DC HSM | Art. It covers equivalent focal lengths of 25.5-60mm in full-frame format . This allows for everything from wide-angle shots to telephoto portraits without needing to change lenses.Sigm´s advanced simulation technology and Super Multi-Layer coating effectively minimize flare and ghosting, delivering contrast-rich images in any situation.Compact and Robust:- With a weight that is over 30% lower than that of the Sigma 18-35mm F1.8 DC HSM | Art and a filter diameter of 67mm (one size smaller than its predecessor), this large-aperture zoom is surprisingly portable. Paired with a compact APS-C body, it´s ideal for travel, everyday photography, and video productions where mobility is key.In addition to a dust- and splash-resistant structure (it is not waterproof, so direct exposure to water should be avoided), the front lens features a special coating that repels water and grease, allowing for safe work in demanding environments.The internal zoom mechanism keeps the lens length constant when changing focal length or focus, making it easier to use handheld, on a tripod, or on a gimbal, and improving its dust and splash resistance.Fast AF with HLA Motor:- The HLA motor provides fast, accurate, and silent autofocus. This smoothness and stability are ideal not only for photography but especially for video, even when shooting with a gimbal or for vlogging.Minimal Focus Breathing:- Focus breathing has been suppressed to reduce changes in the angle of view when adjusting focus, allowing for smooth and natural transitions in video recordings.Multi-function Aperture Ring:- The lens incorporates an aperture ring that provides intuitive control over the aperture. The click mechanism can be disengaged for silent adjustment during recording, and the ring can be locked to prevent accidental movement.The Canon RF version includes a control ring instead of the aperture ring, with no click or lock option.Two Integrated AFL Buttons:- Two AFL buttons are provided that can be assigned various functions from the camer´s menu. Their lateral and superior placement facilitates use in both horizontal and vertical orientations.Available functions may vary depending on the camera used. On the Fujifilm X Mount version, the button allows for AF function selection via a switch on the lens.Art:Exceptional Performance to Enhance Your Creativity:- Lenses designed with the most demanding optical performance in mind, with unparalleled expressive capability. Sigm´s Art line achieves the highest levels of quality.Features:HLA Motor:- The HLA (High-response Linear Actuator) developed by SIGMA directly drives the focusing lenses without gears or other mechanical parts, resulting in silent, high-precision AF.Linear and Non-linear Focus:- Focus movement method for interchangeable lenses for mirrorless camera systems (DN) in relation to the rotation angle of the focus ring during manual focus. With non-linear focus, the amount of focal point movement varies with the rotation speed of the focus ring. With linear focus, if the rotation angle of the focus ring is the same, the amount of focal point movement remains the same regardless of the rotation speed of the focus ring.Focus Mode Selector:- This switch allows you to toggle between autofocus (AF) and manual focus (MF) modes.- On the Fujifilm X Mount version, this switch allows you to toggle between AF Lock and AF functions.Internal Zoom System:- This lens incorporates an internal zoom mechanism that keeps the barrel length unchanged when changing focal length. This provides greater balance and stability during use, and the fact that the front of the lens does not rotate facilitates the use of polarizing filters.Aperture Ring:- Ring for controlling the aperture, designed for more comfortable and intuitive use.- On the Canon RF mount version, the aperture ring functions as a control ring.Aperture Ring Click Override:- This switch allows you to disengage the characteristic click of the aperture ring´s rotation, enabling smooth, click-free operation. This is particularly useful during video recording.- Not available on the Canon RF mount version, where the aperture ring functions as a control ring.Aperture Ring Lock:- A locking system that prevents accidental engagement of the aperture ring during shooting.- Not available on the Canon RF mount version, where the aperture ring functions as a control ring.Two AFL Buttons:- Various functions can be assigned to the AFL button, expanding the range of operations possible with the lens.11-Blade Rounded Diaphragm:- The polygonal shape of a conventional iris diaphragm causes out-of-focus light points to be polygonal. A rounded diaphragm, on the other hand, is designed to produce round out-of-focus light points when approaching maximum aperture. This creates an attractive bokeh effect in many situations, such as when photographing someone with a defocused water surface reflecting light in the background.Water and Oil Repellent Coating:- This lens features a water and oil repellent coating on its front element. This prevents water spots from remaining on its surface and oil and grease from sticking to it. At the same time, maintaining this lens is easier.Dust and Splash Resistant Construction:- This lens features a dust and splash resistant construction with effective sealing at the mount, focus and zoom rings (for SIGMA variable focal length lenses), and other components, allowing photographers to shoot with confidence in all weather conditions.Specifications:- Mounts: L-Mount- Lens Type: Zoom- Focal Type: All-around- Sensor Coverage: APS-C- Maximum Aperture: F1.8- Minimum Aperture: F16- Diaphragm Blades: 11- Optical Construction: 17 elements in 11 groups- Angle of View: L-Mount: 79.7 - 39.1 degrees- Minimum Focusing Distance: 28 centimeters- Magnification Ratio: 1:4.8 (40mm)- Filter or Cap Diameter: 67 millimeters- Dimensions: L-Mount: 72.9x115.9 millimeters- Weight: L-Mount: 535 grams- Included Accessories: Case, Lens Hood LH728-02, Front Cap LCF-67 IV, Rear Cap LCR III. tradeinn Techinn
