One of Sigmas finest creations yet, this lens sets a new benchmark for performance, offering quality that exceeds expectations in every way. Designed with a focus on sophisticated optical performance & abundant expressive power, our new Art line delivers superior image quality for high-level artistic expression. This new lens embodies the concept of our new Art lenses. Compensate for colour aberration to ensure unsurpassed expressive performance Aberration is an important factor for the lens performance. To actualize a high-performance lens, one of the essential elements is aberration correction. When it comes to aberration, there are chromatic aberration of magnification & axial chromatic aberration. It is possible to correct the chromatic aberration of magnification in photo-editing software whereas axial chromatic aberration cannot be corrected afterwards. This lens incorporates FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, & SLD (Special Low Dispersion) glass elements, & by optimizing the power alignment of the lens, both types of aberration have been corrected. The lens achieves ultra-high image quality through the entire focusing range. Also, by appropriate alignment of aspheric lenses, astigmatism & field curvature are corrected. The result is superior optimum resolution even in peripheral areas. Large maximum aperture of F1.4 In 2005, Sigma released a lens that has aperture value F1.4 designed for digital SLRs, “SIGMA 30mm F1.4 EX DC HSM”. Since then, we have produced high-performance lenses by incorporating the latest optical technique, such as the standard lens designed for a full size image sensor, the SIGMA 50mm F1.4 EX DG HSM & the medium telephoto lens with large aperture, SIGMA 85mm F1.4 EX DG HSM. This lens, SIGMA 35mm F1.4 DG HSM, is our fourth lens that achieves extraordinary expressive power at the aperture value at F1.4. For wide angle photography, it ensures excellent brightness with the large F1.4 aperture & a beautiful bokeh effect. Attractive blur effect Correction of coma aberration enabled less blur on a point light source in peripheral areas, & the function is best used for astrophotography & illuminations. It is also possible to create an attractive blur to the out of focus areas. The aspheric lens elements used as the first lens have secured peripheral brightness while correcting distortion. The rounded diaphragm creates an attractive blur to the out-of-focus areas of the image. Floating inner focusing system This system compensates for astigmatic aberration & spherical aberration & provides extremely high optical performance for close-up photos. Flare & ghosting conscious design In order to achieve high rendering on this flagship lens, flare & ghosting were thoroughly measured from an early stage to establish an optical design which is resistant to strong incident light such as backlight. The Super Multi-Layer Coating reduces flare & ghosting & provides sharp & high contrast images even in backlit conditions. Hyper Sonic Motor The HSM (Hyper Sonic Motor) ensures high speed & quiet AF as well as full-time manual focus override by rotation of the focus ring. With the enhanced AF algorithm, smoother AF is achieved. Brass made bayonet mount This lens incorporates a brass made bayonet mount which has both high accuracy & durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength & making it highly resistant to long-term use. ...

Portrait photographers demand the attractive bokeh effect that large-diameter lenses offer, as well as outstanding resolution. Fulfilling the exacting standards of the Art line, the SIGMA 85mm F1.4 DG HSM Art delivers both of these elements at the highest level. The bokeh effect is so precise, you can focus on the pupil of the subjects eye while blurring the eyelashes. Adding to the effect, the area in focus is extremely high-resolution while the bokeh area is very attractive in appearance. The SIGMA 85mm F1.4 DG HSM Art incorporates 14 lens elements in 12 groups, a remarkable structure that helps the lens deliver ultra-high-resolution. This lens is therefore an excellent match for full-frame DSLRs offering 50-megapixel or higher resolution. A design that prioritizes optical performancewithout compromise. Outstanding resolving power & minimized chromatic aberrations help make this the ultimate lens for portraits. To create a top-performing 85mm F1.4 lens, SIGMA leveraged its latest innovations in design & materials. The result is the ultimate lens for portraits. By taking chromatic aberrations to the absolute minimum, this lens offers performance that goes beyond, including incredibly sharp resolution & a beautiful bokeh effect. The beautiful bokeh effect that only a large-diameter lens can offer Elements made from SLD (Special Low Dispersion) glass & an optimized power distribution help minimize axial chromatic aberration. In the areas in front of & behind the point of focus, the optical system produces an attractive & natural bokeh effect by producing a smooth gradation of focus & minimizing streaking. Exclusive low-dispersion glass The degree to which light is refracted by glass depends on the lights wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as secondary spectrum may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) & FLD (F Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance & the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass & optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration. Designed to minimize flare & ghosting From the start of the design process, SIGMA measured flare & ghosting to establish an optical design that is resistant to strong incidental light sources such as backlight. In addition, SIGMAs Super Multi-Layer Coating helps further reduce flare & ghosting & provide sharp, high-contrast images even in backlit conditions. Newly designed HSM for nimble AF control The newly designed Hyper Sonic Motor (HSM) offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance, & the updated AF algorithm helps ensure nimble autofocus performance. In addition, full-time manual focus override allows the lens to be switched to manual focus simply by rotating the focus ringeven during continuous AF. The user can quickly find the perfect focus without needing to touch the focus mode switch. Mount with dust- & splash-proof construction The lens mount incorporates rubber sealing to protect the mount from dust & water drops. The front & rear lenses feature a water- & oil-repellent coating that is particularly useful when shooting in a drizzle, near ocean spray, & in a wide variety of other conditions. Rounded diaphragm The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

EF-610 DG SUPER EF-610 DG SUPER is a multifunctional shoe mount type flash, designed to work with digital SLR cameras from most popular manufacturers & features a powerful Guide Number of 61. Among the diverse features of this flash are the Autozoom function, which automatically sets the illumination angle in accordance with the focal length of the lens; TTL exposure control, which automatically regulates the amount of light; bounce & swivel head functions; Catch Light Panel, which creates a catch light in the eyes of the subject when the bounce flash mode is activated; FP flash, which is capable of synchronizing the flash illumination with high shutter speeds; & the Rear-curtain Synchro flash, which makes delayed synchro photography possible. A Wireless Slave function is also available for use with compatible cameras. Equipped with New TTL Auto Flash Exposure The EF-610 DG SUPER is designed to work with the latest TTL auto exposure systems of most popular manufacturers digital SLR cameras. The camera will control the amount of flash output to achieve the appropriate exposure for the subject. Autozoom function for changing the illumination angle This function automatically sets the optimum illumination angle in accordance with the lens focal length in a range from 24mm to 105mm. When the built-in Wide Panel is used, the flash can cover an angle of up to that of a 17mm lens. Bounce-flash function with movable flash head The flash head can be tilted up by as much as to 90° & swivel to the left by 180°, or to the right by 90°. Bounce photography, in which light is reflected off a white wall or the ceiling or a reflector, increases your range of photographic expression. As the flash head can also be tilted down by 7°, the flashgun can also be used for close-up photography. Catch Light Panel This flash is equipped with a built-in catch light panel, which can create a sparkle in the eyes of the subject when the bounce flash mode is activated. TTL Wireless Flash Function The TTL wireless flash function means that you can obtain the desired lighting effects even if the EF-610 DG SUPER is located away from the camera. It is possible to operate without any extension cord connecting the camera & flash. When multiple flash units are used, the camera calculates the correct exposure automatically. Modelling Flash function Like a studio flash unit equipped with a modeling lamp, the EF-610 DG SUPER also offers a modelling flash function, enabling the user to check for intense reflections & shadows before taking the flash photograph. FP Flash function for high shutter speeds Flash synchronization speed is usually limited to coincide with the full shutter opening of focal plane shutters, limiting the use of high shutter speeds with flash. The FP flash function makes flash photography possible at shutter speeds greater than the normal synchronization speed. When the lens diaphragm is set to larger apertures to limit depth of field in synchronized daytime shooting, high shutter speeds can be used to balance the daylight & the flashlight at any shutter speed. Rear-curtain Synchro flash for natural representation of motion When photographing a moving subject, the Rear-curtain Synchro mode allows the flash to be triggered immediately before the rear-curtain of the shutter closes. Unlike front-curtain synchro, this mode records blurred trails behind a moving subject, rather than in front, for a more natural expression of motion. The Rear-curtain Synchro function can only be used with cameras offering Rear-curtain synchronization. Rear-curtain Synchro Function is not available with some camera models. For details please refer to the compatibility table. AF Auxiliary Light for accurate autofocus in low light conditions As AF may not work efficiently in dark conditions, the AF auxiliary light mechanism of the EF-610 DG SUPER lets you control AF even in situations where autofocusing is difficult.
