From Sigma:
 
SIGMA ELECTRONIC FLASH EF-630 F/CANON is scheduled to start the shipment in MARCH.
 
The SIGMA ELECTRONIC FLASH EF-630 is a multifunctional clip-on type flash, which offers a greater output of light with a guide number 63. Among the diverse features loaded on this flash is TTL exposure control as standard as well as high-speed sync, rear-curtain sync and wireless flash functions. The Auto zoom function which is designed to work with focal length 24-200mm, bounce-flash function, Wide Panel and Catch-light Panel of the EF-630 are perfect for various kinds of photography. The rear LCD offers an intuitive user interface for fast and easy operation. For instance, the new dot matrix liquid crystal display ensures improved visibility of setting status and menu function, and D-Pad and dial on the side of the flashgun make changing settings easier than ever.
 
Key Features:
Intuitive user interface for ease of use
The new dot matrix liquid crystal display is incorporated for this flash. Moreover, the D-Pad and dial on the side of the flashgun make changing settings, such as TTL auto exposure system, wireless flash, FP flash and rear-curtain sync, on the main screen and setup menu displayed on the LCD easier than ever. The flash is designed to disengage easily by one-click on the shoe lock lever. In addition, a flash sync terminal and notification beep sound when the flashgun is fully charged improves ease of use.
 
Guide Number 63 offering a greater output of light
The maximum guide number is 63 for a high light level (when the focal length is 200mm). It is possible to change the illumination angle from 24mm wide to 200mm telephoto. It also covers an angle of a 17mm when used with the built-in Wide Panel.
 
Three light distribution modes
The flash is designed to work in three light distribution modes. Normal emission mode has basic light distribution for general photography, and another mode prioritizes guide number to obtain an even larger output. Flat light distribution mode has a characteristic of uniform light distribution by reducing the fall off of peripheral light. It is possible to select the mode in accordance with the purpose.
 
Bounce-flash function with movable flash head
The flash head of the EF-630 can be tilted up by as much as 90°and can swivel both left and right by 180°. Bounce photography, where light is reflected off a white wall, ceiling or a reflector increases the range of photographic expression. The flash head can also be tilted down by 7°for close-up shots.
 
Wireless TTL Flash Function
The wireless TTL flash function will adjust the desired flash exposure automatically by flash light even if the EF-630 is detached from the camera. Remote control operation is possible between the camera and flash. When multiple flash units are used, the camera calculates the correct exposure automatically.
 
Slave Flash Function
Slave Flash can be used with all camera models and it allows the flash to be fired away from the camera by the master unit though it is not possible to set flash exposure automatically. The Designated Slave function for EF-630 allows the photographer to use two or more EF-630 flash units simultaneously. It is possible to designate flashguns by using different channel settings. In the Normal Slave mode, it is also possible to use the camera's built-in flash or another flash unit as the Master.
 
FP Flash function for high shutter speeds
Cameras with flash focal plane shutters cannot perform flash photography at shutter speeds faster than the fixed synchronization speed as it is usually limited to coincide with the fully open shutter. The FP flash function makes flash photography possible at shutter speeds greater than the fixed 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 and the flashlight at any shutter speed.
 
Rear-curtain Sync flash function for natural representation of motion
When photographing a moving subject, the Rear-curtain Sync mode allows the flash to be triggered immediately before the rear-curtain of the shutter closes. Unlike Front-curtain Sync, this mode records blurred trails behind a moving subject rather than in front for a more natural expression of motion.
 
Multiple Flash Photography
In a single frame it is possible to capture the frozen-in-motion image of a subject by a series of light bursts.
 
AF assist light for accurate auto-focus in low light conditions
Accurate AF may not be possible in dark conditions. However, the AF assist light of the EF-630 allows effective AF between approximately 0.7m and 10m.
 
Manual flash power level control
The flash power level of the EF-630 can be set manually from 1/1 to 1/128 in 1/3 EV increments to meet the photographer’s needs.
 
Modeling Flash function to check for shadow
The EF-630 also offers a modeling flash function, enabling the user to check for reflections and shadows before taking a photograph.
 
Custom Mode Function
The Custom Mode Function is available to register two settings with the photographer’s preference. It is easy to set it with D-Pad and dial on the side of the flashgun.
 
Notification beep sound
When the notification beep sound is turned on by the switch at the front of the flash, it is possible to check the status of flash such as whether it is fully charged, exposure is ok, as well as error alert only by the sound without looking at the LCD display.
 
Auto Power-Off function prevents power waste
To conserve battery life, the EF-630 will automatically turn off after a certain period of time of inactivity.
 
Catch Light Panel
This flash is equipped with a built-in catch light panel, which can highlight the eyes of the subject when the bounce flash mode is activated.
 
Synchronic Terminal
The EF-630 is equipped with a Synchronization Terminal to connect a camera with the commercially available synchronization cable.
 
Regular firmware updates
Photographers can update the firmware via the newly developed optional FLASH USB DOCK FD-11(Sold separately). The firmware can be updated by attaching the EF-630 to the FD-11 and then connecting the FD-11, via a USB cable, to a personal computer on which the exclusive software SIGMA Optimization Pro has been installed.

From Sigma:
 
We are pleased to announce the availability of TRIPOD SOCKET TS-81 that is the optional lens foot which can be attached to the SIGMA 150-600mm F5-6.3 DG OS HSM | Sports. It is compatible with the Arca Swiss quick release plate and the clamp. The deliberately designed length of its rail provides the flexibility to adjust the center of gravity making it balance perfectly, even while zooming or using accessories, such as a tele converter and battery pack. Consideration has been given to the portability and transportation of the lens when Tripod Socket TS-81 is attached. The lens hood can still be reversed and the lens stored in its original padded case, even with the Tripod Socket TS-81 attached. Incorporated into the Tripod Socket are safety stopper screws to prevent the lens from falling. There are 2 sizes of screw holes, 1/4 and 3/8, making it compatible with tripods other than Arca Swiss, too. When it is compared to the supplied tripod socket, it offers more space between the lens and device, and the change of grip has improved the usage as a handle for carrying.
 
 
That last line addresses what I think is a significant design problem with the supplied tripod foot on this lens. While the standard foot is robust and low profile, the second joints of my medium-sized fingers do not fit through the low clearance foot, making it very difficult to carry this lens via the tripod foot. For the same reason, it is also difficult to control the lens by the foot while using a monopod or tripod. While I have not yet used the TS-81, I really like the concept. I previously asked for such a foot as a standard feature.
 
Note that this is not the announcement of a new product; the TS-81 was already announced. Sigma is saying that it is now available. However, we are not finding it available at retailers, even for preorder. We'll let you know when it shows up.

Sigma 30mm f/1.4 DC HSM
 
From Sigma:
 
The Sigma Corporation is pleased to announce the new Sigma 30mm F1.4 DC HSM, the large-aperture APS-C standard lens.
 
“SIGMA 30mm F1.4 DC HSM”, the large-aperture standard lens with an angle of view equivalent to 45mm on a 35mm camera, is a superb go-to lens for artistic photography on an APS-C format digital SLR. Offering the bright f/1.4 aperture and an angle of view extremely close to that of human vision, this lens is ideal for many different types of photographic expression.
 
Featuring an advanced design and the latest manufacturing technologies, SIGMA 30mm F1.4 DC HSM, the large-aperture APS-C format standard lens delivers the highest level of image quality worthy of the Art line. The photographer can leverage the shallow depth of field that creates beautiful bokeh for snap shots, portraits, landscapes, and many different styles of photography.
 
Sigma pioneered the large-aperture, APS-C format, standard lens category with its 30mm f/1.4 lens in 2005. With new optical configurations of nine elements in eight groups, as well as rounded aperture blades, this updated lens delivers pleasing sharpness and a beautiful bokeh background. Its minimum focusing distance is 11.8 inches and its maximum magnification ratio is 1:6.8. The lens’ optimized power distribution helps to minimize field curvature, prevent a loss of image quality at the edges of photographs and produce outstanding image quality. Its double-aspheric lens minimizes spherical distortion, astigmatism and coma, and its rear focus system prevents focus-dependent variation in aberration. Together, the new optimized auto focus (AF) algorithm and rear focusing system ensure smooth and accurate focusing. The new 30mm f/1.4 is also compatible with Sigma’s new USB Dock, which will enable firmware updates and focusing adjustments, is expected to be available in coming months.

Sigma Corporation of America announces pricing and availability for 180mm F2.8 macro lens
 
Sigma 180mm f/2.8 EX DG OS Macro HSM Lens
 
World’s first 1:1 180mm F2.8 macro lens arrives in the US in July for street price of $1,699
 
RONKONKOMA, NY July 13, 2012 – Sigma Corporation, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, has announced that the Sigma APO Macro 180mm F2.8 EX DG OS HSMwill be available in the United States on July 27 for the street price of $1,699.
 
The new APO Macro 180mm F2.8 EX DG OS HSM lens boasts Sigma’s proprietary Optical Stabilizer (OS) technology and a wide F2.8 aperture to allow faster shutter speeds for narrow depth of field. With the OS feature, the lens offers the use of shutter speeds approximately four stops slower than would otherwise be possible, enabling handheld, close-up photography. Three “F” Low Dispersion (FLD) glass elements, which have a performance equal to fluorite glass, are included to provide excellent correction for color aberrations, and an inner focusing system enables this lens to photograph objects precisely throughout the entire focusing range. Overall length does not change during focusing.
 
“Macro photography is becoming quite popular and we’ve been growing our lineup of macro lenses as a result,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “We’re filling a gap in the industry by introducing the world’s first 1:1 180mm F2.8 lens to the market. The Optical Stabilizer technology and the larger focusing distance also provide photographers with more control for highly sensitive subjects that are on the move, like butterflies and insects.”
 
Equipped with the Super Multi-Layer Coating feature, the APO Macro 180mm F2.8 EX DG OS HSM lens reduces flare and ghosting, and delivers sharp and high contrast images, even in backlit conditions. The incorporation of Sigma’s Hyper Sonic Motor (HSM) ensures quiet and high-speed autofocus, as well as full-time manual focus override capability. The macro lens has a rounded nine-blade diaphragm to create an attractive blur to the image’s out-of-focus areas. At 1:1 magnification, this lens has a focusing distance of 18.5 inches, which is a greater working distance than shorter focal length macro lenses, making it advantageous when taking pictures of highly sensitive subjects. It is also compatible with Sigma’s 1.4x EX DG APO and 2x EX DG APO Tele Converters.
