HTC EVO 4G LTE, Exclusively from Sprint, First HD Voice-capable Smartphone Available in the U.S.; Offers Best-in-Class Features, including Beats Audio, Amazing Camera and HD Display, next-generation EVO offers the ability to enjoy industry-leading features without fear of overage charges or throttling with unlimited data plans for new and existing Sprint customers. The first thing you'll notice about the HTC Evo 4G LTE (hereafter referred to as just the HTC Evo 4G, for simplicity's sake) is that it's rather large in size and it has a 4.7-inch super LCD (720p) display, but the phone feels light and is comfortable to hold. Navigating through Sense 4.0 on the HTC Evo 4G and in and out of apps was fast and fluid, thanks to the 1.5GHz, dual-core Qualcomm Snapdragon S4 processor and the standout feature by far on the HTC Evo 4G is the 8-megapixel camera, which uses the same HTC ImageSense software and ImageChip as the company's One line of phones. The only other qualms you might have about the Evo 4G is the top glossy back cover, which doesn't really fit in aesthetically with the rest of the smartphone's look and the Evo 4G LTE will be available for pre-order starting May 7 and will cost $200 with a new two-year contract from Sprint.



Sprint, the only national wireless carrier offering truly unlimited data for all phones while on the Sprint network and HTC, a global designer of smartphones announce the next evolution of the award-winning HTC EVO family: HTC EVO 4G LTE. HTC EVO 4G LTE focuses on exceptional improvements in camera technology, audio and voice quality on both the network and device.

HTC EVO 4G LTE is built on Android 4.0, Ice Cream Sandwich, integrated with HTC Sense 4. HTC EVO 4G LTE boasts brilliant features, including a vibrant 4.7-inch HD display, HD voice capabilities, 1.5GHz dual-core processor, large 2000mAh embedded battery and dual-cameras (8-megapixel rear-facing and 1.3-megapixel front-facing) with instant capture capability. HTC EVO 4G LTE brings back the fan-favorite kickstand built into the smartphone's refined, slim design. With the launch of HTC EVO 4G LTE, Sprint becomes the first U.S. carrier to announce plans for a nationwide HD Voice network beginning in late 2012 as part of Sprint's Network Vision program. HD Voice is the next-generation evolution of voice quality and the future of voice communications for mobile phones. The service will provide fuller, more natural-sounding and less fatiguing voice quality and should reduce troublesome background noises often found in a cafe or on the street.2 Users should expect to identify voices and hear every word better than ever. Sprint's commitment to HD Voice starts with HTC EVO 4G LTE, Sprint's first HD Voice capable device. "Sprint has a long history of leading the wireless industry in innovation, and the debut of HTC EVO 4G LTE marks another chapter in that innovation story," said Sprint CEO Dan Hesse. "Once again, we are partnering with HTC to deliver the benchmark Android device for the year with the next generation of our award-winning EVO brand. We know our customers will appreciate the focus on audio and voice quality with EVO 4G LTE, including the addition of Beats Audio and HD Voice capability."





HTC EVO 4G LTE is Sprint's first device with HTC's Authentic Sound experience integrating Beats Audio. The technology enables customers to hear music the way the artist intended with unique audio tuning that delivers thundering bass, soaring midrange and crisp highs. HTC EVO 4G LTE incorporates Beats Audio across the entire phone experience, including playing music stored on the device, streaming from a favorite service, watching a movie or YouTube video, or playing the latest hot game. HTC Sync Manager software also lets users easily get their music on the device from their PC and it works with current programs, including iTunes. "The partnership between HTC and Sprint has resulted in one of the most popular and successful smartphone brands of all time with over 7 million EVO devices sold to date," said Jason Mackenzie, president, HTC Corporation. "With HTC EVO 4G LTE, we've created a desirable successor that is sure to excite the millions of current EVO customers and beyond with HTC's distinct design, amazing camera and authentic sound." In addition, HTC ImageSense technology combines hardware and software advancements to the camera lens, sensor and software, including integration of a new custom HTC ImageChip, to take great photos even in adverse conditions. The best-in-class f/2.0 camera lens lets in 44 percent more light than the lenses used on most camera phones. The Smart Flash also adjusts the flash strength based on how far away the object is, so users won't get photos where everything looks washed out. Crafted from aluminum spaceframe in an anodized black finish, HTC EVO 4G LTE delivers cutting-edge function and style in a thin and distinctive design. The smartphone's 4.7-inch display and 80-degree viewing angle makes it easier to share pictures and video with others. The multiposition kickstand allows users to watch videos hands-free. HTC EVO 4G LTE customers can enjoy an unlimited data experience with Sprint Everything Data plans. Sprint's Everything Data plan with Any Mobile, AnytimeSM includes unlimited Web, texting and calling to and from any mobile in America while on the Sprint Network, starting at just $79.99 per month for smartphones3 – a savings of $40 per month vs. Verizon's comparable plan with unlimited talk, text and 2GB Web, or $10 per month savings vs. Verizon's 450-minute plan with unlimited text and 2GB Web. Advancing smartphone photography :

• HTC EVO 4G LTE makes mobile photography and video easy and intuitive.
• The on-screen photo and video buttons are right next to each other so users don't have to switch modes. This allows the user to take video and still photos concurrently.
• It makes the whole idea of "video mode" or "photo mode" irrelevant. While shooting a video, the user can just tap the shutter button and it captures a still image of that exact moment. Still images can also be captured during video playback.
• HTC EVO 4G LTE's camera has a super-fast start-up and auto-focus time. With the fast auto-focus, users can easily stay with a moving object or person, taking numerous pictures just by holding the shutter button.

Panasonic Lumix GF5 Ultra Compact Digital Interchangeable Lens System Camera, Overhauls Touch Interface With Swappable-Lens Review

Panasonic Lumix GF5 looks identical to its predecessor, offers similar specs for $100 more, an interchangeable-lens camera built for casual users, the mirrorless Lumix GF5 will have a dramatically redesigned touchscreen interface. With the Lumix GF5, Panasonic reaffirms its commitment to a small, consumer-focused compact system camera with limited controls and a touchscreen interface. After the introduction of last year's GF3, there was quite a bit of foment among enthusiasts who thought it was too small, and too consumer-focused and this resulted in a quick about-face, as Panasonic seemed to hastily prepare the GX1 from the 2009 blueprints of the GF1, with only a few minor tweaks to set it apart. The same might be said of the Panasonic GF5, as major new features are few. The GF5 is clearly designed with beginners in mind, more advanced photogs should consider the GX1, but with a $599 sticker price (with 14-42mm lens), it's sure to be a hit.




Panasonic announced a new digital interchangeable lens system camera, the LUMIX DMC-GF5, which joins Panasonic's award-winning LUMIX G Series of digital cameras, which are acclaimed for their high image quality with small and compact body and lenses. The LUMIX GF5 features a newly developed 12.1-megapixel Live MOS sensor and redesigned Venus Engine, helping to ensure true-to-life images through exceptional resolution, image rendering and color reproduction. Even in low-light situations and at a maximum 12800 high ISO sensitivity, the LUMIX GF5 produces stunning photos and videos. The noise reduction system includes a combination 3DNR (3D Noise Reduction) and MNR (Multi-process Noise Reduction) allowing for both bright areas and dark areas to be faithfully reproduced with minimal noise in high sensitivity image recording. Sporting a sophisticated and stylish design, the LUMIX GF5 features a compact, lightweight body with built-in flash. A rubberized grip makes it easier for users to comfortably hold the camera in one hand. Complying with Micro Four Thirds standard, a wide range of interchangeable lenses is offered to expand photographic experience even more broadly at higher level of photo quality. "Panasonic expects the LUMIX GF5 to please photo enthusiasts and budding photographers that are looking for the next step from the traditional point-and-shoot camera," said Christopher Rice, Senior Product Manager, Imaging, Panasonic Consumer Marketing Company of North America. "The camera's host of shooting options makes photography even more artistic, yet easy for users of any experience level. The powerful Venus Engine and sensor allows the camera to achieve exceptional photo quality in a range of shooting environments."





The LUMIX GF5, like all cameras in the LUMIX G Series, adopts Contrast AF (Auto Focus), so focusing is controlled by the image sensor. Compared with the Phase difference system AF, Contrast AF boasts higher accuracy, especially when shooting with a bright lens with small F value. To further advance the Contrast AF, the GF5 incorporates full-area focusing, making it possible to set focus on any point in the field of view. Featuring an ultra high-speed Light Speed AF, the LUMIX GF5 can focus in approximately 0.09 seconds making it possible to capture even fast moving subjects clearly. Combined with Touch AF control and high-speed burst shooting at four frames per second in full resolution, it has never been easier to capture fast-moving objects clearly. Additionally, Pinpoint AF allows for even more precise focus by further enlarging the focus area, assisting, for example, to set focus directly on the pupil of an eye. The LUMIX GF5's large, 3.0-inch 920,000-dot high-precision touch display and Graphic User Interface (GUI) provide users with ease of use and simple operation. The touch-control system immediately allows users to set focus on a subject just by touching the screen and users can even release the shutter to snap a photo directly from the touch screen. Once a user locks onto a subject by a touch, the camera will track the subject with the AF tracking function, even if the subject moves. Touch Zoom is also available when the LUMIX Power Zoom Lens H-PS14042 lens or H-PS45175 is mounted. Creative Control Mode has been upgraded from the LUMIX DMC-GF3 by increasing filter options available on the LUMIX GF5 from six options to 14, adding Soft Focus*2, Dynamic Monochrome, Impressive Art, One Point Color, Cross Process and Star Filter, in addition to the conventional Expressive, Retro, High Key, Sepia, Hi Dynamic, Miniature Effect and recently introduced Low Key and Toy Effect modes. With the new GUI menu tab, switching filter effects is seamless. A preview of filter effects can be seen on the large LCD screen via Live View mode and the camera intuitively recommends filters depending on the scene that the camera detects in iA (Intelligent Auto) or iA Plus mode.




For beginner users of interchangeable lens system cameras, the GF5 features a new Scene Guide offering 23 sample pictures shot by professional photographers. Users can choose the photo closest to the situation that they are shooting and optimal parameters for shooting the scene will be set automatically. Additionally, procedures, technical advice and recommended interchangeable lens options for the scene can be shown to allow users to better understand and learn photography. In addition to shooting still photography, the LUMIX GF5 can also record 1920x1080 60i* full-High Definition videos in AVCHD format which excels in both compression efficiency and compatibility with AV equipment for playback. In addition to practical full-time AF, the Touch AF in video recording also lets the user enjoy professional-like selective focusing which allows the focus to be changed while shooting video. The LUMIX GF5 features a dedicated video record button on the top of the body so users can instantly start recording videos while shooting photos without having to make setting adjustments. Along with full-HD video capabilities, the LUMIX GF5 also features high-quality sound, recorded with Dolby Digital Stereo Creator. Videos can be recorded in MP4 format for playback on a PC or other portable electronic devices without having to convert the files. Additional features of the LUMIX GF5 include:

• iA mode to automatically activate a range of technologies to enhance photos without adjusting settings every time conditions change, including AF Tracking, Intelligent D-range Control, Intelligent Scene Selector, Face Recognition and Intelligent ISO Control.
• iA Plus mode allows users to adjust defocusing area in the background, exposure compensation and white balance for more flexible control.
• A dedicated sensor that automatically determines shooting angle, making it possible to tell whether a photo was taken horizontally or vertically no matter what lens was used.
• The GUI interface allows users to choose an image and set it as wallpaper for the menu screen.

The LUMIX DMC-GF5 will be available in black, white and red later this year in the following kit options: Body with 14-42mm standard zoom lens will have a suggested retail price (SRP) of $599; body with 14-42mm power zoom lens will have an SRP of $749. The competitive market in the GF5's class:

Panasonic GF5 versus Olympus E-PM1

Going up against the small Olympus E-PM1, the Panasonic GF5 is a little taller, but the E-PM1 is wider. The X-Vario lens is noticeably shorter than Olympus's redesigned mechanically retractable lens, both retracted and extended. The E-PM1 achieves a shorter stature, yet includes a full hot shoe and accessory port, while the GF5 supports neither. That's partly due to the wider-aspect LCD screen on the E-PM1.

Panasonic GF5 versus Panasonic G3

Even though the Panasonic G3 is pretty darn small, it's clear why Panasonic still makes the GF5: to really show how small they can make a compact system camera for those who want such a creature. The G3 is larger thanks to its electronic viewfinder hump on top, its full hot shoe, and is most cumbersome because of the rear protrusion for the viewfinder. Enthusiasts will appreciate its greater number of controls, though, including a mode dial, rear control dial, and its articulating screen. A model for everyone.

Thanks :(1), (2)
