Sigma Announces Two New Mirrorless Cameras: Sigma sd Quattro and sd Quattro H
Interchangeable lens APS-C and APS-H Foveon Quattro sensors in state-of-the-art camera systems
Sigma Corporation of America, a leading camera, DSLR lens, flash and accessories manufacturer, has announced the new high-performance, compact Sigma sd Quattro and Sigma sd Quattro H mirrorless camera systems with Foveon Quattro sensors. The Sigma sd Quattro features an APS-C sized sensor and the Sigma sd Quattro H touting a larger APS-H sized sensor for even greater image quality. Thanks to the mirrorless aspect of the cameras, both the sd Quattro and sd Quattro H are designed to take full advantage of all Sigma Global Vision lenses.
“With the introduction of these two new cameras, Sigma continues its rich history of innovation. The Foveon sensor is renowned for its imaging characteristics, and the mirrorless interchangeable format offers photographers the full line of Sigma Global Vision lenses to help realize their creative visions,” stated Mark Amir-Hamzeh, President of Sigma Corporation of America. “The sharpness of detail and nuanced color tone captured by the Foveon sensors is a key component of Sigma Global Vision. The sd Quattro, and the sd Quattro H, with the newly announced Foveon Quattro APS-H sensor, will be greatly appreciated by photographers who demand the utmost in imaging purity, with the added benefit of portability for both in-studio and on-location photography.”
Both the sd Quattro and sd Quattro H feature similar design aspects with a compact form consistent with the dp Quattro line, making them highly portable and utilizing the Foveon Quattro sensor for exceptional imaging quality and fast processing. A magnesium-alloy body makes the sd Quattro and sd Quattro H durable and rugged, while a dust- and splash-proof design makes it ideal for photographers facing harsh conditions. In addition to the new body design, both cameras boast a list of useful advancements. These include a two-mode Autofocus detection that combines Phase Detection for focus speed and Contrast Detection for focus accuracy. The focus settings have also been enhanced with such modes as Movement Prediction, Face Detection, Free Movement, Focus Peaking and a variety of others. The new 2.3-megapixel viewfinder displays close to 100% of the field of view and when placed in “Auto” will toggle between the viewfinder when the user has the camera to their eye and then to the LCD when the user lowers the camera. A new “Super-Fine Detail” mode brings out the full potential of the Quattro sensor by capturing seven different exposures with one shot and merging them for exceptional dynamic range (images can be extracted individually as well). Meanwhile an updated algorithm for the Auto White Balance allows for greater accuracy, even with multiple light sources.
While the sd Quattro and sd Quattro H are similar in physical design details, they stand apart when their Foveon sensors are compared. The sd Quattro utilizes the same sensor found in the dp Quattro line and produces image quality comparable to that of a 39-megapixel Bayer-pattern sensor on resolution testing. The stacked silicon Foveon Direct Imaging sensor captures all detail information on the top 19.6-megapixel layer along with all color information for the Blue channel, while the two five-megapixel layers below capture Red and Green color information, all without the need for a low pass filter. Merged together they create incredible image quality that is comparable to medium format files. The sd Quattro H boasts a larger APS-H sensor (26.6 x 17.9 mm) than the sd Quattro and can produce images equivalent to that of a 51-megapixel Bayer-pattern sensor camera on resolution testing. The sensor structure is similar to that of the sd Quattro but uses a 25.5 megapixels on the top layer of the sensor that captures the detail information. Both cameras use the latest Dual TRUE III image processor and take full advantage of the Art, Contemporary and Sport line Global Vision lenses that are made for high megapixel cameras. Like all Sigma Cameras, RAW (X3F) data can processed via Sigma Photo Pro, which offers editing options, including Monochrome mode to take advantage of the incredible monochrome images the Foveon sensor captures.
Sigma Announces the EF-630 Multifunctional External Flash
Boasts TTL exposure control, high-speed sync, wireless flash functions, rear-curtain sync, auto-zoom, and wide-angle illumination coverage and more
Sigma Corporation of America, a leading DSLR lens, camera, flash and accessories manufacturer, has announced the Sigma Electronic Flash EF-630, a multifunctional flash designed to work with current digital SLR cameras. Offering greater output of light, the EF-630 features TTL exposure control, high-speed sync, wireless flash functions, auto-zoom and bounce-flash, amongst additional features that make it ideal for many types of photography.
“Lighting is one of the most important factors when it comes to creating a beautiful image and can be the difference between capturing the perfect moment and missing it entirely,” comments Mark Amir-Hamzeh, president of Sigma Corporation of America. “The EF-630 has all the features advanced photographers look for in a flash and is the perfect companion to the DSLR.”
The Sigma EF-630 flash automatically adjusts for focal lengths of 24 mm to 200 mm, making it ideal for wide angle and super-zoomed shots alike. For ultra-wide angle shots, photographers can utilize the built-in Wide Panel to cover an angle of up to that of a 17-mm lens.
Compatible with most well-known digital SLR cameras, the EF-630 features auto TTL exposure control, as well as remote control operation through the TTL wireless flash function, where the camera lens calculates the correct exposure automatically for perfect lighting. For multi-flash setups, photographers can use the Slave Flash Function to trigger additional flashes. To achieve a softer look, photographers can bounce light off of a white wall, ceiling or reflector by tilting the EF-630’s flash head upwards by as much as 90° or by swiveling left or right by 180°. For close-up shots, the flash head can also be titled down by 7°.
The FP Flash function of the EF-630 makes flash photography possible at shutter speeds greater than the normal sync speed, which is typically limited at shutter speeds up to 1/250 s for most cameras. The FP Flash function for high shutter speeds is necessary when setting a larger aperture to limit depth of field when shooting in daylight, as high shutter speeds are used to balance the daylight and the flashlight at any shutter speed. To capture natural motions, the Rear-curtain Sync mode allows the flash to be triggered immediately before the rear-curtain of the shutter closes, recording blurred trails behind a moving subject rather than in front.
Additional EF-630 features:
- Intuitive user interface: dot matrix LCD screen for improved menu visibility, D-Pad and dial settings controls, and easy one-click disengage function improve ease of use
- Modeling flash function: check for intense reflections and shadows before capturing the shot
- AF assist light: accurate auto-focus in low light conditions
- Auto Power-off: flashgun automatically powers off after a period of non-operation to conserve battery life
- Manual flash power level control: manually sets the flash power level from 1/1 to 1/128
The new EF-630 Flash can be updated with the latest software from a workstation or laptop using the Sigma Optimization Pro software and Flash USB Dock (sold separately).
