Posted by: Mark Peters

Panasonic is pleased to introduce a new Lumix digital camera, the 8.1-megapixel DMC-TZ4, featuring a 28mm wide-angle 10x optical zoom Leica DC lens. The 28mm wide angle lens captures the subject and the scene wider at the same standpoint than normal 35mm camera does and you can zoom in or out to magnify a distant subject when desired with the 10x powerful optical zoom. The Lumix DMC-TZ4 is the latest member of the Lumix TZ family, boasting an Intelligent LCD function, which detects the lighting condition and controls the brightness level of the LCD in 11 fine steps, to offer a display with most appropriate clarity in any situation with a newly developed 230,000-dot resolution in 2.5-inch.

Panasonic TZ4 - Intelligent Exposure & Digital Red-eye correction
The Intelligent Auto mode, which comprises various shooting-assist functions, has been advanced for the Panasonic Lumix DMC-TZ4 by newly adding the Intelligent Exposure feature and Digital Red-eye Correction in addition to the conventional Mega O.I.S., Intelligent ISO Control, Intelligent Scene Selector, Face Detection and Quick AF functions. Mega O.I.S. suppresses hand-shake and Intelligent ISO Control prevents motion blur. The Intelligent Scene Selector sets the appropriate scene mode by automatically selecting it from the most frequently used scene modes, such as Portrait, Scenery, Macro, Night Portrait and Night Scenery. The Face Detection system detects human faces to set the focus and appropriate exposure for them automatically. The unwanted red-eye effect caused by the use of the flash can be digitally corrected. The newly added Intelligent Exposure function automatically controls the ISO sensitivity partially to increase the exposure of only the darkened area due to backlighting or insufficient flash lighting to capture the scene as you see it by suppressing the extreme brightness and darkness in the picture. The Continuous AF system allows the Lumix TZ-4 to keep focus on the subject even without pressing a shutter button halfway, to get best result out of a shutter chance by minimizing the AF time. Once you enter iA mode, these multi-capable functions happen automatically so you can shoot without the bother of adjusting settings every time conditions change. You can enjoy easy, trouble-free shooting in any situation and get the satisfaction that comes with capturing clear, beautiful images.

Panasonic DMC-TZ4 - Venus Engine IV processor
The high-performance image-processing LSI has newly entered its fourth generation, to be reborn as Venus Engine IV to assure higher-quality pictures with an advanced signal processing system. Slideshows of captured images now offer a music effect that matches the mood so you can enjoy watching or showing your pictures with emotional impact. Integrating a high performance, multi-capable lens and a host of unique, easy-to-use functions in the compact body, the Panasonic TZ4 is the ideal camera for traveling.

Panasonic Lumix TZ4 - 10x Optical zoom lens
The 8.1-megapixel DMC-TZ4 packages a 28mm wide-angle Leica DE Vario Elmar lens with 10x optical zoom (equivalent to 28-280mm on a 35mm film camera) into a compact body. Comprising 11 elements in 9 groups, including an ED (extra-low dispersion) lens and 3 aspherical lenses, this advanced lens unit realizes the outstandingly compact body yet passing Leica's stringent standards and delivers an exceptional optical performance. The 28mm wide-angle lens makes it easy to fit the whole group into a photo indoors or to capture dynamic wide-perspective shots of a sweeping landscape or large architectural structure. Further, in 3-megapixel resolution mode, the Extra Optical Zoom function provides additional magnification, extending the zoom power to 15.9x by using the centre part of the CCD. Using this feature in combination with the 4x digital zoom provides a total zoom factor of up to 63.8x. This powerful zoom also works during the motion picture recording.

Panasonic Lumix TZ4 - Intelligent Auto mode
Panasonic incorporated the Intelligent Auto mode in pursuit of the ultimate ease of operation and the reduction of misshots. This mode is also further advanced with the inclusion of the Intelligent Exposure feature for the DMC-TZ4. Mega O.I.S. (Optical Image Stabilizer) to compensate for hand-shake and Intelligent ISO Control to detect and suppress motion blur are built into all Lumix cameras, as the industry’s most advanced countermeasures against blurring. Both image stabilizing technologies have been further advanced in detection accuracy and correction effect thanks to the new image-processing LSI, Venus Engine IV.

Panasonic TZ4 - Scene modes & Face Detection
In addition to these two paramount anti-blurring technologies, Panasonic continues pursuing the ideal that anyone at any technical level of photography should be able to take beautiful pictures with ease, by incorporating the Intelligent Auto mode. Increasing the number of scene modes is one thing and taking advantage of them is another, and that’s where the Intelligent Scene Selector comes in. It automatically sets the appropriate scene mode according to the scene you’re going to take from among the most frequently used scene modes, such as Portrait, Scenery, Macro, Night Scenery and Night Portrait mode. The Face Detection system helps the camera to recognize human faces and to focus and set the exposure automatically. Up to 15 faces can be recognized simultaneously. The Continuous AF system allows the camera to keep focus on the subject while the camera is in recording mode even before without pressing a shutter button halfway, to get best result out of a shutter chance because the focus is always near the subject and the AF time is minimized.

Panasonic DMC-TZ4 - Intelligent Exposure function
A newly incorporated Intelligent Exposure function increases the exposure only in under-exposed areas by detecting the brightness level part-by-part in the picture. If the background includes the sky, which tends to be easily washed out, the camera automatically adjusts the aperture and shutter speed to keep the setting slightly under-exposed to prevent wash-out while brightening the darkened area by increasing the ISO only in that area. If the background of an indoor portrait receives insufficient lighting from a flash and becomes dark, the ISO sensitivity is raised in only the low-lit area to make it brighter without causing graininess in the subject's face. The result is a picture with well-balanced exposure on the whole.

Panasonic Lumix DMC-TZ4 - Trouble-free shooting
These multi-capable functions happen automatically, so you can shoot without the bother of adjusting settings every time conditions change - the powerful Intelligent Auto Mode does all the work for you. You can enjoy easy, trouble-free shooting in any situation and get the satisfaction that comes with capturing clear, beautiful images.

Panasonic Lumix TZ4 camera - High definition photos
All Lumix cameras can take 1920x1080 pixel HD (high-definition) quality photos that perfectly fit a wide-screen (16:9) HDTV for full-screen viewing. This powerful zoom in the Panasonic DMC-TZ4 also works during the motion picture recording to capture the distant subject close, making the movie more dynamic. With newly added HD component output capability, you can enjoy watching stunning still and motion pictures taken by your Lumix TZ4 by simply connecting the camera to the HDTV via an optional component cable (DMW-HDC2).

Panasonic TZ4 digital camera - Slideshows
The Panasonic Lumix TZ4 newly provides slideshows complete with music. Just select the pictures you want to show and choose the mood that best matches your selection from natural, slow, urban or swing, and you'll get an emotion-filled slideshow with a variety of slide change effects and matching music without any annoying adjustments. If you make the slideshow with HD photos in 1920 x 1080 pixels, you can also enjoy watching an impressive HD slideshow with music on a large-screen HDTV by using the optional component cable.

Panasonic DMC-TZ4 - Intelligent LCD function
The Panasonic Lumix DMC-TZ4 incorporates a newly developed easy-to-see 2.5-inch and 230,000-dot LCD for comfortable viewing while both monitoring shots in detail and playing back the results even in thumbnails as tiny as 30-split. The Intelligent LCD function detects the light condition and automatically boosts the LCD backlighting by max. 40% when shooting outdoors in bright sunshine, and adjusts the frame rate when shooting in low-lit situations in addition to using the pixel mixed readout method to secure clarity in such situations. Detecting the lighting condition precisely and automatically controlling the brightness with a total of 11 fine steps, this function gives the display the most appropriate clarity in any situation without using extra energy. The High Angle mode makes the LCD screen extremely easy to view when the camera is held high, such as when shooting over a crowd.

Panasonic Lumix TZ4 - Image-Processing LSI
A new image-processing LSI, Venus Engine IV, features more advanced signal processing technology for rendering even higher-quality images. Notably, parallel noise reduction in both luminance signal and chromatic signal processing systems, a technology established by the preceding Venus Engine III, gains a more sophisticated process. First, the luminance noise is two-dimensionally separated into high-frequency and low-frequency noises and only the low-frequency noise, which tends to be conspicuous, is eliminated without affecting the high-frequency noise that greatly influences resolution. Second, the information of the change point between colors is minutely stored for precise determination of edges, thus color bleeding is dramatically suppressed. This not only produces a clearer image in high ISO sensitivity recording, but also faithfully reproduces details in low-lit areas of pictures taken at low ISO sensitivity.

Panasonic Lumix DMC-TZ4 - Venus Engine IV
The Venus Engine IV also elevates the detection accuracy and corrective effect in both Mega O.I.S., which prevents hand-shake, and Intelligent ISO Control, which suppresses motion blur. Featured in the new Lumix DMC-TZ4, the multi-task image-processing engine Venus Engine IV supports a super-fast response time. The shutter release time lag is as short as 0.008 second and the camera's quick response makes it easier to capture sudden, spur-of-the-moment photo opportunities. In burst shooting mode, the 3 shots can be snapped per second at full resolution. And in High-Speed Burst shooting mode, it fires off an incredible 7 shots per second. You also get unlimited consecutive shooting, which lets you keep shooting until the memory card is full. The Venus Engine IV also supports a High Sensitivity mode that lets the Panasonic TZ4 record at a setting of up to ISO 6400, sensitive enough to capture subjects in near-total darkness without using a flash.

Panasonic DMC-TZ4 digicam - Long battery life
The new Panasonic Lumix DMC-TZ4 features a variety of functionalities to expand the convenience and fun for users to enjoy taking beautiful pictures. The energy-efficient Venus Engine IV imaging engine contributes to the long battery life to shoot around 330 shots despite its large, bright LCD on a single battery charge. A total of 21 scene modes help you to take more beautiful pictures in a wide range of situations.

Panasonic Lumix TZ4 - Title Edit function
Also interesting is the Title Edit function, which allows text to be input as additional information of the picture, for example, names of children or pets, and travel places. These information, as well as dates, which can be helpful when making a photo album, can be stamped on photos with the Text Stamp function whether you print them yourself at home or have a photo shop do them. Around 50 MB of internal memory is built-in to back up the SDHC/SD Memory Card recording and copying.

Panasonic TZ4 - Graphic User interface
As design improvements, all new Lumix cameras incorporate a REC/PLAYBACK mode switch. This helps the photographer to instantly switch between recording and playback modes, knowing which mode the camera is in. The GUI(Graphic User Interface) has been upgraded to look more futuristic in terms of design and color while maintaining the visibility of characters. The major features mentioned above can be quickly understood with the newly installed slideshow program called Demo mode. Clad in a stainless steel, the Panasonic Lumix DMC-TZ4 will be available in silver and black. The Panasonic Lumix DMC-TZ4 is compatible with optional marine case (DMW-MCTZ5) with which users can shoot underwater while scuba diving, etc.
