Technology in my vision

The next-generation SDXC (eXtended Capacity) memory card specification, announced today at the 2009 International CES, dramatically improves consumers’ digital lifestyles by providing the portable storage and speed needed to store weeks of high-definition video, years of photo collections and months of music to mobile phones, cameras and camcorders, and other consumer electronic devices. The new SDXC specification provides up to 2 terabytes storage capacity and accelerates SD interface read/write speeds to 104 megabytes per second this year, with a road map to 300 megabytes per second.

The SDXC specification, developed by the SD Association, leapfrogs memory card interface speeds while retaining the world-leading SD interface. Specifications for the open standard will be released in the first quarter of 2009. SDHC, Embedded SD and SDIO specifications will also benefit from the new SD interface speeds.

“SDXC combines a higher capacity roadmap with faster transfer speeds as a means to exploit NAND flash memory technology as a compelling choice for portable memory storage and interoperability,” said Joseph Unsworth, research director, NAND Flash Semiconductors, at Gartner. “With industry support, SDXC presents manufacturers with the opportunity to kindle consumer demand for more advanced handset features and functionality in consumer electronics behind the ubiquitous SD interface.”

Turning mobile phones into media centers
SDXC allows users to enjoy more from their mobile phones. Larger capacity and faster transfer speeds allow for expanded entertainment and data storage. A 2TB SDXC memory card can store 100 HD movies, 480 hours of HD recording or 136,000 fine-grade photos.

“With SDXC, consumers can quickly download higher quality content to their phones, including games, video and music – giving consumers a richer media and content experience,” said James Taylor, president of the SD Association. “The SD interface already has proven itself valuable in mobile phones. Now, SDXC memory card capabilities will spur further handset sophistication and boost consumer content demand.”






Shooting pictures at the speed of life
SDXC is also the first memory card specification to provide 2TB storage without hindering the high-speed performance necessary for high-end photography. It will provide maximum speeds even when the SDXC specification achieves its maximum 2TB storage capacity.

"SDXC is a large-capacity card that can store more than 4,000 RAW images, which is the uncompressed mode professionals use. That capacity, combined with the exFAT file system, increases movie recording time and reduces starting time to improve photo-capturing opportunities,” said Shigeto Kanda, general manager at Canon. “Improvements in interface speed allow further increases in continuous shooting speed and higher resolution movie recordings. As a memory card well suited to small-sized user-friendly digital cameras, the SDXC specification will help consumers realize the full potential of our cameras."

SDXC will enable camcorders to provide longer, professional level HD video recording with a small form factor.

The SDXC specification uses Microsoft’s exFAT file system to support its large capacity and interoperability in a broad range of PCs, consumer electronics and mobile phones. The exFAT system was designed for increased compatibility with flash media, from portability of data to interoperability with multiple platforms and devices on removable media.

“The SD Association is committed to answering and anticipating consumer demand for easy-to-use memory card storage that is interoperable in any device with a matching SD slot,” Taylor said. “The SDXC card gives consumers a new, yet familiar, high-performance card that will be used in hundreds of manufacturers’ device offerings.”

Pretec creator of the highest capacity CompactFlash card in the world (100GB) and the fastest CF card in the world (433X), continues today its record breaking history in the field of speed and capacity by unveiling the extraordinary 666X CF card, the world’s fastest CF card.

Four times faster than a typical CF card, Pretec 666X CF’s dazzling 100MB/s speed is the largest speed boost in CF history. 666X CF card is the newest member of Pretec’s family of innovative flash memory cards, consistently first to market in high speed and capacity products; 233X and 333X CF cards were introduced by Pretec at Taipei in 2007, 64GB CF card started shipping in Sept. 2008, and 433X CF card were launched at Birmingham UK in Feb. 2009.

Pretec 666X CF card will likely also be the last of the high speed CF card in the CompactFlash industry, since 100MB/s speed is approaching the theoretical maximum speed of CF specification, which is 133MB/s. CompactFlash Association has released the new generation of the CF specification, CFast™, which breaks the speed limit from 133MB/s of the Parallel ATA (PATA) standard to 3Gb/s (375MB/s) Serial ATA (SATA II) architecture while keep the small and popular original CF mechanical form factor. Pretec has announced the world’s 1st CFast™ since CES 2009 in Las Vegas, also demonstrated here in CeBIT and PMA; which will continue to be the speed and capacity leader (up to 6Gb/s) in small form factor memory card for the years to come.

With metal housing and ruggedized construction, Pretec 666X CF card provides extensive ruggedness making the card resistant to impact & shock – at least 10 times more durable than a typical CF card, and enables photographers to make the best use of rapid capture of high resolution pictures in the studio, streets or elsewhere with confidence and piece of mind even under the most severe conditions.

Pretec’s CeBIT booth is featuring “Double 100” this year, with dual breakthrough of CF capacity in 100MB, and CF speed in 100MB/s; approaching the end of an era with legendary CompactFlash, and pointing to the next rising star of CFast™.

Pretec 666X CF card will start sampling by April from capacities of 4GB to 64GB.

Nearly 18 months after it first appeared as a prototype at trade shows, Sony has announced its eagerly anticipated flagship digital SLR, the Alpha 900 - finally giving Minolta/Konica Minolta users a full frame option. Featuring the 24.6 MP CMOS sensor announced in January, the Alpha 900 offers several enticing features, including sensor-shift image stabilization, a super 100% coverage viewfinder and the same high resolution screen as the Alpha 700






SAN DIEGO, Sept. 9, 2008 – Sony is introducing its full-frame α (alpha) DSLR-A900 camera, aimed at serious photo enthusiasts looking for traditional SLR performance with the added benefits of digital photography.

It is designed to deliver ultra-fine picture quality with the world’s highest resolution, 24.6-megapixel, 35 mm full-frame CMOS sensor and fast image processing with a new dual BIONZ® processing engines. The camera is also the first to have a body-integrated image stabilization system for a full-frame sensor with Sony’s SteadyShot® Inside anti-shake system.

One look at the camera’s distinctive pentaprism and nostalgic body design will evoke its full-frame optical performance. It features a bright, clear optical viewfinder with 100% field of view coverage that would impress even film photography loyalists.

“The α (alpha) DSLR-A900 introduction solidifies Sony’s position as a leading camera manufacturer that can meet the demands of serious enthusiasts,” said Phil Lubell, director of digital camera marketing at Sony Electronics. “It represents the best in sensor and image processing technologies and offers enhanced functions, performance and reliability so photographers can push their creativity to the limit.”

Ultra-Fine Images As The Human Eye Perceives Them
The camera’s Exmor™ CMOS sensor delivers the photographic expressive power of wide angles and perspective that only a 35 mm full-frame sensor can offer, and is designed to take advantage of the resolving power of high-precision α (alpha) lenses. Its high pixel count and large size provide enhanced image detail and a wider dynamic range for natural color reproduction and subtle tonal gradations.

The sensor is produced using proprietary Sony planarization technologies to ensure an ultra-flat surface across the entire imaging area. Instead of a single analog/digital convertor, the sensor uses over 6,000 on-chip, column-parallel A/D converters to convert analog signals to noise-resistant digital signals at the earliest possible stage. The result is reduced noise and high-speed transfer of data.

Image processing gets a boost in speed and power from the application of two BIONZ image processing engines. Large amounts of data captured by the 24.6-megapixel sensor can be quickly processed to achieve a fast shooting response. Additionally, this dual BIONZ processing system applies advanced noise reduction algorithms producing images of exceptional quality and detail, especially at high ISO sensitivities.

World’s First Anti-Shake System for a Full-Frame Sensor
The camera’s newly-developed, body-integrated SteadyShot Inside unit achieves an anti-shake effect equivalent to shutter speeds faster by 2.5 to 4 stops. This new unit provides stabilization for Sony, Minolta and Konica-Minolta wide angle, large-aperture lenses, which is difficult for lens-integrated systems.

State-of-the Art Optical Performance and Responsiveness

The ultra-bright viewfinder with 100% field of view coverage and 0.74x magnification enables accurate framing and preview. It features a high-power condenser lens, an eyepiece with high reflective-index glass, and a multi-layer, anti-reflective coating on every optical surface to deliver its extraordinarily bright and accurate view.

Additionally, the focusing screen is user-replaceable, with additional L-type (grid pattern) and M-type (super spherical acute matte) screens sold separately.

The camera’s newly-developed autofocus system consists of nine wide-area sensors with 10 assist points for improved tracking of moving subjects. A center dual cross sensor comprised of two horizontal and two vertical line sensors as well as a dedicated f/2.8 sensor are included to achieve greater precision, especially when using fast-aperture lenses.

It also offers high-speed continuous shooting of 24.6 megapixel images at five frames per second. A newly-designed mirror box features a unique parallel-link mirror mechanism that moves on two horizontal axes to accommodate both 100% viewfinder coverage and the body-integrated image stabilization system without increasing the camera’s size. The mirror box also has a new moving magnet actuator, a high-powered coreless motor for a faster shutter charge, and a magnet catcher to minimize mirror bounce and light refraction within the box.

Versatility to Unleash Creative Possibilities
The model’s innovative intelligent preview function takes the guesswork out of setting up a shot and the hassle of taking multiple shots to achieve a desired effect.

After pressing the depth of field preview button, the camera “grabs” a RAW preview image which is processed and displayed on the LCD screen. You can then fine tune white balance, determine the best level and effect of dynamic range optimization, adjust exposure compensation and check histogram data, all before you actually take the picture. Preview images are not recorded on the camera’s memory card, thus saving capacity.

Other key features aimed to expand creative options include the Dynamic Range Optimizer (DRO) with five levels of user-selectable correction as well as DRO bracketing for enhanced scene analysis and graduation optimization. EV bracketing with ±2EV range makes it easy to create high dynamic range composite images.

Thirteen creative styles can be selected to enhance images and then fine-tuned by customizing contrast, sharpness, zone matching and other parameters, while 3 user-programmable memories provide instant access to as many as 26 different mode settings.

Powerful RAW file processing control is put in the photographer’s hands with the included Image Data Converter SR3 software that delivers faster file processing speeds, easy adjustment of image parameters, Dynamic Range Optimization and a new Peripheral Illumination function that compensates for corner light fall off.

With the camera’s HDMI output and Photo TV HD mode, your creative output can be enjoyed on a compatible HD television. This mode brings the look of actual printed photography to the television, by fine-tuning such image parameters as sharpness, gradation and color.

Comfort in Your Hands
Its construction features rugged, lightweight magnesium alloy with moisture-resistant, rubber seals for buttons and dials, an anti-static coating to prevent dust adherence to the imager, and a high-endurance shutter rated for more than 100,000 release cycles.

It has a 3-inch, Xtra Fine LCD screen (921K) makes it possible to check focus and image quality with accuracy. It incorporates an easy-to-see display with a quick navigation menu to easily access common functions without interrupting your creative flow. A backlit LCD panel sits on top of the camera and displays key settings.

System Expansion with New Accessories
The A900 camera will be accompanied with an array of accessories like the recently-announced Sony HVL-F58AM flash unit with its innovative Quick Shift Bounce system, powerful performance with a guide number of 58, and wireless auto flash ratio control.

The Sony® VG-C90AM vertical grip offers the same ease of operation when shooting vertically as horizontally, with its button layout and low-position shutter-release button. It also houses two InfoLITHIUM® batteries (sold separately) for longer shooting and playback.

Leica has today unveiled a brand new autofocus DSLR system designed for professional users, which is configured around a 30x45mm sensor (i.e. 56% larger than 35mm full-frame). The S-system will utilize an advanced new dual shutter, with both an in-body focal plane shutter for fast lenses, and in-lens leaf shutters for high flash sync speeds. The first camera, the S-2, will feature a 37.5 megapixel CCD sensor in a weatherproof body which is similar in size and handling to conventional 35mm-type DSLRs. The new ‘Maestro’ image processing system provides twice the operating speed of current medium-format backs, significantly reduced power consumption, and allows production of in-camera JPEGs. The company has also developed a range of nine new lenses, including macro, ultra-wideangle, and tilt-and-shift designs. New images added.


LEICA S2 – Remarkable new camera from Germany redefines the professional DSLR class with a custom 37.5-megapixel, 30 x 45 mm sensor built into a 35mm-sized body.

Some companies tweak the features. At Leica, we transform the concept. That’s why the introduction of the flagship Leica S2 is not merely an incremental advance. It is nothing less than a watershed event that sets an entirely new performance standard for professional digital SLRS.

With a custom 37.5-megapixel, 30 x 45 mm sensor that is 56% larger than full frame, it establishes parameters of imaging excellence that are well beyond those obtainable by conventional pro-caliber DSLRs. In the Leica tradition, it utilizes the classic 3:2 aspect ratio that corresponds to the human field of vision and is widely acclaimed as the “Leica Format.”

In designing this brilliant new camera, Leica’s engineers took a close look at the best existing DSLR designs and then synergized them into a radical but practical new camera that combines the performance parameters of a medium-format digital camera with the ergonomics, form factor, and handling ease of a 35mm SLR. The result is the new Leica S2, an entirely new, finely crafted, professional tool developed in-house by Leica with hands-on input from some of the most renowned professional photographers in the world.

It incorporates an advanced new dual shutter system with in-body focal-plane shutter for fast lenses, and in-lens leaf shutters for high flash sync speeds, an ultra-high-precision autofocusing system, a new series of lenses designed for the highest possible performance with the new sensor, and a Maestro image processing system that provides twice the speed of comparable medium-format backs, reduces power consumption, and provides in-camera JPEG capability. Remarkably, all of this has been incorporated into a camera that is smaller than a full-size professional 35mm SLR, and still has the unmistakable look and feel of a Leica.

Like Leica cameras of the past, we designed the new Leica S2 from the inside out, and its robust styling is a classic example of form following function. We began with a cutting-edge, large-format CCD sensor and literally configured the camera around it rather than adapting existing technologies. In this way we achieved a new level of performance without sacrificing size or convenience. Yes the S2 Leica is our latest masterpiece, an unequivocal statement to the world that showcases our technological prowess. But it is more than just a technological tour de force.

It is a statement of Leica’s continuing pre-eminence in the world of imaging that goes back nearly 100 years. Perhaps that is why our top executives in Germany have compared the announcement of the Leica S2 to the debut of the first Leica, the legendary model A in 1925. That seminal camera did nothing less than redefine 35mm photography in the 20th century and we believe that the Leica S2 may well do the same for DSLR photography in the 21st.

With Salzburg ACM Projektentwicklungs GmbH as its new owner, Leica Camera AG is entering a new era. Following in-depth and successful re-structuring, the business can now concentrate on investing in new products. Leica has made a quantum leap in the field of digital technology, enabling it to combine the advantages of highly developed digital technology with the classic Leica values concerning optics, mechanics and optimal image results.

The result of this is uncompromising cutting-edge technology; the LEICA S2 is the first to offer all these things to professional digital photographers. The LEICA S system sets the trend for future Leica products in terms of technology and leads the way for future product ideas from Leica Camera AG.









The lens range will consist of 24mm ultrawide, 30mm tilt-and-shift, 35mm wide, 70mm standard, 30-90mm standard zoom, 100mm short tele, 120mm macro, 180mm telephoto, and 350mm telephoto optics (all of which will apparently incorporate leaf shutters).

This super telephoto lens has the longest focal length of an interchangeable lens for AF SLR cameras at the time. Silent and fast AF is realized using a ring USM (Ultrasonic Motor) and rear focusing system. Extremely sharp, professional-quality images are realized through use of two large-diameter artificial crystal fluorite lens elements (3rd & 6th) that thoroughly eliminate secondary spectrum. Although the optical design is the same as FD1200mm f/5.6L (prototype), this lens is optimized for the EF system with a nonlinear focus cam for moving the focusing lens group, a focus preset function for quick focusing at a predetermined point, and power manual focusing with three focusing speeds. A one-touch revolving mechanism for quick switching between vertical and horizontal formats is possible. Extenders EF1.4X or EF2X transforms the lens into a manual focusing super-super-telephoto 1700mm f/8 or 2400mm f/11 lens.

The average film camera has for the last 50 years used either 120 rollfilm or so-called 135 film, 135 being by far the most commonly used type. Each frame of 135 film is 36x24 milimeters, while the average consumer dSLR camera today has a sensor size of approximately 60% of this, around 23x15 milimeters. The sensors in digital compacts are much smaller still. Within this tiny space, the camera and its lens has to compress the vast amount of detail visible to the human eye. The resulting replications of reality are far from perfect, they can't be.

One way of partially overcoming this problem is quite simply to use larger film formats or digital sensors. Within the digital realm, the 48x36mm sensor size available in certain medium format digital backs is pretty much as large as it gets without substantial R&D resources (like what a major corporation, national government or army might have at their disposal).

In film, things are a bit simpler. While constructing huge digital sensors is a challenging task, creating a huge sheet of film or photographic paper is really – simply put – just a matter of making it bigger than usual, and building a camera large enough to house it.

The biggest 'instant' camera I know of is Polaroid's 20x24'' behemot. It's 1.5 meters tall and weighs in at 106 kilos. The Polaroid paper sheets used in this camera is, as the name implies, 20 x 24'', which equals 50x60 cm. Keeping in mind that the aforementioned 135 film is a mere 3.6 x 2.4 cm, it's easy to see why such a larger-than-life camera would be capable of producing prints of far superior detail compared to smaller formats.

A number of these cameras are available for hire, complete with a dedicated studio space, in San Fransisco, New York and Prague. Following Polaroid's recent announcement that they will completely cease the production of their signature instant film, there is a certain risk that these cameras will be destined for the museum soon.

Perhaps the most "sensible" of the items presented in this list, this is nevertheless one of the heftiest tele zoom lenses for SLR cameras around. While the zoom range of 200-500mm is nothing new or exciting, it's the maximum aperture of an incredible f/2.8 throughout the focal range that makes this such a special lens.

While a lot of tele lenses have a distinct cannon barrel look, Sigma have apparently done all they can to enhance that trait, giving the lens a leafy green finish. The end result is an extremely fast tele zoom lens that could easily be confused with a surface-to-air missile launcher.
