As mentioned above, the Lumix TZ20 has an excellent optical zoom range just as the TZ10 does. What wasn’t mentioned above though is that it actually improves on that range making the 12x zoom lens in the TZ10 pale in comparison. Instead of just a 12x zoom, the Lumix TZ20 is capable of an astounding 16x optical zoom thanks to its 24mm ultra wide-angle LEICA DC VARIO-ELMAR lens. Between the 16x optical zoom capability and the 24mm wide-angle lens, you can bet that you’ll have a much wider viewing space, allowing you to capture as broad a picture as you want of the farthest objects spot.

Even more impressive perhaps, is the fact that the 16x optical zoom does not work for image capture alone, but is also available in movie recording. This means that you don’t have to limit yourself to stunning still images of faraway objects, but can capture even the farthest of events unfold through a fully zoomed video capture. And with the separate one-touch movie record button now located at the top surface of the camera, you can easily switch to video recording without having to put down your camera.

The Panasonic Lumix TZ20 zooming capacity doesn’t end with its 16x optical zoom lens either, it also boasts of being capable of up to 21x zoom via the Intelligent Zoom. The Intelligent Zoom makes use of the Intelligent Resolution Technology, which extends the zoom ratio by about 1.3x while ensuring that the picture quality doesn’t suffer. However, you should note that zooming in beyond the 16x optical zoom range will mean picture resolutions of less than the maximum 14.1 megapixels, albeit still resulting in really sharp images.  Now this is a feature you wont often find on other digital cameras.

If you do want to zoom in beyond even the 21x that the Intelligent Zoom function supports, you can actually do so thanks to the Extra Optical Zoom function that extends the camera’s zoom power to as much as 33.8x. This zoom power is made possible by using the centre part of the 1/2.33-type MOS sensor. Note though that images captured using the Extra Optical Zoom function will have resolutions of 3-megapixels or less.

Zooming in is also a breeze with the TZ20 thanks to the camera’s touchscreen operation.

With the rather overwhelming zoom power of this camera, you can bet that it lives up to the name that Panasonic dubbed it – the Super Zoom Digital Camera.

Advances in technology mean that the simple camera has and is continuing to evolve with new features being added to better older models and update and refine the Digital cameras.

As one model improves to another with more sophisticated technology and manufacturers add new features and functions consumer choice is increased and decision making becomes ever harder.

This is why it is important to think about the specific features that will be most beneficial to your photography and to find out which models include them.

Today, most models of DLSRs come with a set of basic modes and functions to the user. These functions and modes include movie mode, live view, High ISO performance, image stabilisation, dynamic range optimisation and LCD screens.

The movie mode is often the most attractive of the functions offered by manufacturers and high-end brands. The ability to record HD video on digital slr camera allows the consumer to record and upload excellent videos or even to make art house film projects.

Live view with clear and HD picture quality using the LCD screen allows you to compose various shots. This makes it easier to take pictures from tight angles or from the ground where it might be harder to use optical viewfinders.

The High ISO performance allows the photographer to take images in low light conditions which will reduce the loss of detail, colour and pixilation appearing in the image. The camera’s ISO capabilities will help avoid bad image quality.

The image stabilisations are often found in mid-range and the high-end cameras. Images often appear blurry if the camera is moved slightly during exposure. This is often caused by using a slow shutter speed in low light or whilst using a telephoto lens. The image stabilisation technology will help avoid this.

A camera’s dynamic range refers to the spectrum of light the sensor that can capture before either the highlights blow or the shadow areas become indiscernible.

This mode allows photographers to avoid the dilemma of choosing exposure contrast as the Cameras did not allow for highlights and shadows in different light conditions. This allows the user to capture images that have a more natural look.

The advent of digital technology for recording still and moving pictures in other words, digital cameras and digital camcorders has made it easier than ever to take holiday snapshots, or to record family events, such as birthdays, weddings, etc.. Digital cameras and camcorders are often compact enough to slip into a pocket or bag, easy to operate, and provide results that can be viewed almost instantaneously. Digital images can also be easily transferred to a computer for editing, and distributed, or shared, via CD, DVD, email or the Internet.

Digital Camera & Camcorder Features

Digital images are all about “resolution” the number of individual picture elements, or “pixels”, of which an image is composed and this is a term that you frequently see bandied about in the specifications of digital cameras and camcorders. Unlike traditional, analogue devices, digital cameras and camcorders rely on a photosensitive chip either a CCD (“Charge Coupled Device”) or a CMOS (“Complementary Metal Oxide Semiconductor”) positioned behind the lens to capture an image, or series of images. It is the number of pixels, or “megapixels” shorthand for 1,000,000 pixels in the sensor, and the size of individual pixels, which determines the clarity, and overall quality of the image(s) produced.

Generally speaking, the higher the number of pixels the better, although the more pixels a digital image contains the larger the size of the file required to store that image. This may have a bearing on the type, and size, of storage medium that you choose for your digital images. Digital camera typically employ “flash”, or solid state, memory expansion cards ranging in capacity from 16Mb to 8GB, or more as storage media. A 3 megapixel (Mp) camera with a 16Mb memory expansion card is capable of storing just 6 digital photographs, at maximum resolution, so you need to think about your storage requirements. Digital camcorders are typically more flexible when it comes to storage media, and offer a choice of Mini DV digital cassette tape, Mini DVD an 80mm, or 3″, version of standard DVD and hard disk storage.

Digital Camera & Camcorder Reviews

From the current crop of digital cameras & digital camcorders on the market, two that stand out for compactness and versatility are the Coolpix P80 from Nikon and the Xacti VPC-CA65 from Sanyo. The Nikon P80 is a 10Mp digital camera with an integral storage capacity of 50Mb, compatible with SD, and SDHC, memory expansion cards. It also features an “18X” optical zoom lens one of the longest available on a compact digital camera but has dimensions of 79mm x 110mm x 78mm, and weighs in at just 365g. The Sanyo Xacti VPC-CA65, on the other hand, is a portable digital camcorder and digital stills camera, featuring an adjustable 150,000 pixel LCD, and capable of recording video at 640 x 480 pixels, 30 frames per second. The Xacti VPC-CA65 is also waterproof, to a depth of 1.5 metres
