Sony NEX-VG10 Digital Camera

In May 2010, Sony made its debut on the market with a direct visual system when it launched the first two models in the NEX in life - the Sony NEX and NEX-3-5. Both cameras are based on the combination of an APS-C 14.2-megapixel Sony Exmor CMOS image sensor and a BIONZ image processor, and both accept interchangeable lenses courtesy of the new Sony E- mount. NEX cameras not only offers photographic skills, but also the possibility of high-definition movies for inclusion in the resolution of 720p or 1080i-3 NEX NEX-5. The new mount had the opportunity to rethink a simultaneous ground to the design of lenses and brings several clear advantages for video than competing products. NEX cameras both offer continuous autofocus, useful when its record of openness, and is continuously variable to avoid a sudden change in brightness for the opening. Some design decisions made in the two cameras - and especially their extremely compact body style - said their attention to taking still pictures, but with the video function is only useful in a sequence in which property or a short dedicated camera is not available.

Aware of this, Sony has announced to break the introduction of NEX cameras, was the development of an interchangeable lens camera. The project was to share the same mount and Sony cameras NEX, so that the lens divided between the two product lines. Only a few months after the 25th anniversary of the famous line of Sony Handycam is the Sony Cyber-VG10 that promise much, borrowing much of Sony NEX-5 turned on, but put it in a body design that is much better suited for recording video, and a variety of changes in hardware and firmware to combine the NEX-VG10 a really interesting product for video recording.

Hewlett Packard SW450 Digital Camera

Hewlett Packard Digital Camera SW450 is based on a combination of a "1/2.3 CCD image sensor with a resolution of 12.2 effective megapixels and a 4x optical zoom. The HP SW450, the objective is real focal lengths ranging 5, from 05 to 20.2 mm, which corresponds to a range of 29 to 110mm equivalent angle to a useful range of -. 35 mm Maximum aperture varies from f/6.3 to 2.8 moderate distance over the entire range of zoom.

Images are framed and only one "LCD panel from 2.7 to discuss with the HP SW450 refrain from any form of optical viewfinder or electronic. 50-1600 ISO sensitivity ranges usually equivalent. At a reduced resolution of three megapixels or below, the upper limit increases the ISO 3200. Dropping the resolution is only 1.2 megapixel camera opens the maximum sensitivity of ISO 6400 equivalent. A generous 25 scene modes, including portrait and love the party, so that some degree of control over the appearance of images. Both features Smile Shutter and Blink Detection is available to do portraits of their best.

EXIF 2.2 compatible and JPEG images can be used in the HP SW450 AVI (Motion JPEG) recording format, although it is not the resolution and frame rate in more detail in the technical product. Data is stored on cards or SDHC Secure Digital, but not newer SDXC types. Power comes from a lithium-ion battery and charger is also included in the bundle of products. Connectivity includes USB, not speed / type.

Hewlett Packard SW450 is set at about $ 130 in price, and is finished in turquoise and red. A guarantee 1 year limited hardware is included.

Ricoh GXR Digital Camera

Ricoh GXR characteristics of optional modules that allow the lens and the sensor will be replaced together. The body of the device itself is not much talk about the LCD screen, a connection for an optional external viewfinder, battery and SD slot for flash memory, more memory, flash shoe, microphone and speakers, and various controls and quadrants. The meat of the camera - the image of its target, the sensor and (suspected) processor - you can find the forms. At launch, two lens / sensor modules are available for the Ricoh GXR. Offer a wide 3x optical zoom 24mm to 72 mm aperture f/2.5 equivalent variable to f/4.4 across the zoom range, while the other is a fixed focal length of 50 mm with an aperture of f / 2.5.

Each optical module has its advantages and limitations compared to alternatives. The module smallest and lightest zoom offers optical image stabilization by moving the sensor allows a sensitivity as low as ISO 100 can be as close to an inch fire, enabling a macro zoom mode, scene, and offers a range of 410 shots. On the other hand, uses a much smaller 1/1.7 "CCD image sensor with a resolution of slightly less than ten million pixels, about half the rate of burst of 1.6 frames per second in JPEG mode requires the reduction of noise at 800 ISO or higher applied, does not allow shutter speeds faster than 1 / 2000 sec, and does not offer standard and high definition movies at 24 fps Flash pace wide with this module is to 20 cm -. 4.5m with wide-angle and 15 cm - 2.7 m TV.

The 50mm equivalent lens module is now a much larger APS-C image with a small "top twelve megapixels, the rate of combustion increases up to three frames per second in JPEG mode, the shutter speed faster than can a / 3200 second allows noise suppression to be disabled at any resolution and can record HD (1280 x 720 pixels), although 30 frames per second will be replaced with 24 fps. To achieve this, compromises the mechanical image stabilization, a minimum detection limit of ISO 200, is not to focus on more than seven inches, the body weight of 98 grams and has increased the depth of 32 , 7 mm and is battery life by almost a quarter of the 320 shots. The flash range with this module is 20 inches to three feet.

What is the magnesium alloy body of the device itself is dominated on the back of an LCD "3.0 with high 920,000-dot resolution, making the region of 640 x 480 pixels, with three points for color. A six built-in flash modes including red-eye reduction, flash exposure compensation of -2.0 and provides strength, in addition to manual control in twelve steps to a full / 64th of maximum power. The images will be stored on SD or SDHC cards or in approximately 86MB of internal memory. file formats include Adobe. DNG RAW and JPEG still images and movies compatible with OpenDML AVI Motion JPEG. Connectivity includes NTSC / PAL standard definition and high definition video HDMI connector on C-Mini HDMI and USB 2.0 high speed data transmission. power from a 3.6-volt lithium-ion DB -90. is connected to the body size of 113.9 x 70.2 x 28.9 mm and modules and weighs only 160 grams without the body of a module.

The unusual form-based design is to offer several significant advantages. With the combination of the lens and the sensor in a single element, Ricoh can make sure that the sensor and lens designs are complementary to each other needs. The project also provides size and weight advantages over exchangeable lens cameras with fixed sensors - reducing the size of the image circle smaller than a sensor that will take place, while a compact fixed lens may relatvely a larger sensor the size Zoom can use the ability to better lighting. Finally, with a sealed form, the powder can be kept out of the sensor - at least for lenses with internal focusing and zoom or fixed focal length and the internal design.

For lenses with an external focus and a zoom mechanism, the project could have the opposite effect, however. The zoom effect, or (to a lesser extent), which is like a plane moving slowly (and with it, dust) inside and outside of the lens barrel - and once that it reaches the sensor, there is no way to manually clean again in a sealed module. This is the normal state of affairs for fixed lens digital compact, but offers a possible limitation of the Micro Four Thirds cameras and digital SLR cameras, in which the sensor can be cleaned easily be compared. Grouping lens and the sensor in a module means that any lens purchase should be as a sensor - usually one of the most expensive components in an APS-C camera. It also means that both parties must be replaced if they are not covered by warranty. Similarly, advances in sensor technology will grow rapidly, can not be used with all current objectives of the system, and acquire new targets needed if the appropriate forms are available. Design is also more complex electronic links - only instead of passing data to and from the lens power, so auto-focus, aperture setting, the lens correction of defects, etc. the design of this power, still images / video stream requires sight, flash control, etc. must all be passed between the module and the body. There is also an element of confusion is that the basic functions of the camera as an image and the resolution of the film is the shutter speed available, changes, etc. depending on the module is installed.

We can not be the first company to experiment with the range of interchangeable modules on the market, a pair of lenses and the sensor in a housing connected to a camera body. That honor goes to Minolta DiMAGE EX1500 offered, about 11 years - and, curiously, also made his debut with the election of a 3x Zoom-form or a form to a fixed focal length. If the camera is Minolta has not been successful enough to provoke, if you provide the company extra lens / sensor modules, and only two additional modules have never been offered for the camera - a module and a hot shoe module for 3D photography MetaFlash, Both the joint between the camera and lens module / sensor. The DiMAGE EX1500 also provided an opportunity not found in the car Ricoh - housing and the module must be connected in a different direction so that the objective that the display is connected via a short cable.

While U.S. prices have not yet been officially announced, the camera and both forms already known retail store in the United States have been published. Use road pricing is a steep $ 550 for the camera without a form. Street prices for the optical module 50mm equivalent APS-C is $ 830, and from 24 to 72 mm zoom lens in the form equivalent to 1/1.7 "sensor is another $ 440 Total cost to bring the system without optional external viewfinder for $ 1820. Ricoh with something of a challenge in which two cameras are not dissimilar to match the specifications can be purchased together for several hundred dollars less.

Sigma SD15 Digital Camera

Announced in September 2008 at photokina in Cologne, Germany, is the Sigma SD15 is a direct successor of the now rather long-in-the-tooth SD14 model, which was announced in September 2006 with delivery in March 2007. The Sigma SD15 records almost the same APS-C-(0.98 / 24.9 mm diagonal), Foveon X3 image of the SD14. This imager is 14.1 million 7.8μm photodiodes, and is capable of full RGB color information in each pixel location. The Sigma SD15 is a maximum size of 4.64 megapixel images (interpolated left with the "Super High" mode 4608 x 3072 pixels has been a decrease in sheet). The crude reduced resolution modes are no longer included in the data sheet and can be removed from the camera, with native resolution 2460 x 1720 pixels, now the only option appears first.

The SD15 has marked the debut of the new brand Sigma TRUE II ("Three-layer Responsive Ultimate Engine"), image processor, a camera SD series, updated with the Sigma DP2 is the only model of the function II processor TRUE. (The original TRUE processor fitted only in the DP1 compact camera DP1s. Previous SD-series DSLR without a processor-image are presented.) Sigma TRUE II processor is designed to provide improvements in processing speed , operation and performance.

Perhaps the most striking change in the review of the SD15 compared to its predecessor on the back, where there is a new, larger 3.0-inch LCD with a resolution of 460,000 points significantly higher than the 150,000-point at 2, 5 "panel of the SD14. Rear panel controls are also slightly redesigned and transferred the functions of some keys to fit in a rapid series of condensed Sigma-key as the latest series DP. The only other change is an external flash card indicator to the lower right corner of the rear panel of the camera, even if, after opening the compartment flash cards, a change of CF / Microdrive, SD / SDHC / MMC media (but not Recent gender SDXC) is equally clear body size. total is unchanged, but the SD15 reaches a weight of 20 grams or 0.7 ounces, fell impressive in light of the large LCD screen (and most likely to spend with an SD slot.)

A nice change firmware a few have been made since the SD14. Series 3200 - the current range of the camera sensitivity to ISO 100 to ISO 800 and corresponds to an extended position is certified ISO 1600 by a new standard range of ISO 100 to 1600, with the possibility of replacing the outer limits of ISO 50 We extend Today, it is also a position of ISO Auto, which typically selects from ISO 100 or 200 and as high as ISO 400 when using the flash. The SD14 is evaluative, and center weighted metering modes at the center have been replaced by a choice of evaluation, center-weighted or spot. The SD15 features a selection of seven different color modes - Standard, Vivid, Neutral, Portrait, Landscape, black and white and sepia. The SD15 is now listed as compatible with DPOF so that job creation on the memory card, which can be understood by some printers. Finally, the Russian language was added to the list of options available in the firmware SD15 ..

The Sigma SD15 has begun at the end of June 2010 with road pricing in the region of U.S. $ 989
