25mm Ultra Wide-angle Lens
The DMC-ZS7 features a 25mm ultra wide-angle* 12x optical zoom f/3.3-4.9 Leica DC Vario-Elmar lens (35mm camera equivalent: 25-300mm). Incorporating Panasonic's advanced optical technologies, this lens system is comprised of 10 elements in 8 groups, with 2 ED (Extra Low Dispersion) lenses and 2 aspherical lenses / 3 aspherical surfaces while preserving compactness.

Inheriting the fine rendering and outstanding quality of the Leica Elmar lens, this easy-to-carry camera delivers beautiful images any time, any place.
* Converted to standard 35mm camera equivalent, at the maximum wide position.
The 25mm ultra wide-angle lens* has about twice the shooting area as a standard 35mm lens. This enhances all kinds of shooting situations, like when you're photographing a group of people at an indoor party or shooting a large structure or sweeping landscape while traveling.
* Converted to standard 35mm camera equivalent, at the maximum wide position.
HD Movie in AVCHD Lite
In addition to Motion JPEG images, the DMC-ZS7 can record high-definition motion images in AVCHD Lite. It features almost double the recording time in HD quality compared with the conventional Motion JPEG format. Also, with the DMC-ZS7, it is possible to use the GPS (Global Positioning System) function to record data on the shooting location. You can view images for each geographical location by using the included software PHOTOfunSTUDIO 5.1 HD Edition to manage the images by date and location.
Powerful 12x Optical Zoom
The addition of AVCHD Lite HD movie recording doubles the appeal of the DMC-ZS7. This single camera lets you capture virtually all images in their natural beauty. It gives you both motion and still images, and ranges from 25mm ultra wide-angle* shots of sweeping landscapes to powerful 12x optical zoom shots (35mm camera equivalent: 300mm) that pull distant subjects right up close. The mechanism design minimizes the noise of auto focusing or zooming.
* Converted to standard 35mm camera equivalent, at the maximum wide position.
High Quality Sound
A stereo microphone, featuring Dolby Digital Stereo Creator, on the upper body records dynamic, true-to-life stereo audio that brings out the power of your HD movies.
Travel Mode with GPS for both Photos and Movies
By simply turning on the GPS function, the location data and time are automatically updated. Great for travel recordings. The DMC-TS7 camera is acclaimed as an excellent travel companion because of a wide shooting range and hybrid recording capability of high quality photos and movies. The DMC-ZS7 further enhances its value by adding a built-in GPS (Global Positioning System) unit into the camera.
Customer Reviews
I've got my ZS7 today - the camera is just great! A superior Leica lens with a high-resolution sensor, advanced image processing, and plenty of sophisticated features in a small but very solid and stylish body.
PROS:
- Solid metal body, stylish design, nice dark-blue color
- Very convenient one-hand grip, unusual for such a small pocket-size body
- Short startup time (1-1.5 sec), no shutter lag, fast auto focus
- A dedicated Movie-button for instant recording
- Big 3" colorful "juicy" display visible even in direct sunlight
- Intuitive menu plus very convenient Quick-menu with a dedicated button
- Excellent quality Leica lens: sharp and contrast in the entire zoom range
- Wide 25mm (35mm equiv.) is very convenient for indoors
- Huge 12x optical zoom (up to 300mm equiv.) in such a compact design
- Two-speed of zooming - fast/slow controlled by the lever
- Smooth and silent auto focus and optical image stabilization
- Best in the industry "iAuto" mode - you can really trust it!
- New "Intelligent Resolution" feature greatly improves the image quality
- Creative Aperture- and Shutter-priority and full Manual modes
- Three independent scenery modes including "High Dynamic" range scene
- New GPS feature for those who travel a lot
- Very good movie quality in 720p AVCHD mode looks like a full 1080 HD one
- High-quality stereo microphones
- Accepts SD/SDHC and new SDXC huge capacity memory cards
CONS:
- A mechanical lever for switching between shooting and playback modes
- Some soft "sh-sh-sh" noise while zooming in and out (but no "clicks")
- I wish more sensitivity for low-light shooting
BUILD: The ZS7 camera looks and feels as good as it's predecessor DMC-ZS3. The design is almost as the same, just the power switch and the mode dial exchanged their places. One significant addition - a GPS mark on the top, right above the lens. The blue color is not that dark as on TZ5 and not so striking bright as on ZR1. A slight dent on the back with some prominence on the right side makes a very convenient grip to operate with one hand. A metal body looks pretty solid, however it is not that heavy.
PERFORMANCE: The new camera has a pretty good performance: the startup time is a little bit more than 1 sec and with almost zero shutter lag. Taking into account a new very quick "Sonic Speed" auto focus, which takes about 0.35-0.4 sec, you will be able to catch virtually every spur-of-the-moment photo. And a dedicated movie button allows starting video recording at any time without any preparation.
LENS: Leica lens is just excellent: unusually big for a so small body 12x zoom starting with the very convenient for indoors shooting 25mm up to telephoto 300mm (equiv.) plus a quick and precise auto focus (however might be somewhat slower in low-light), and good optical image stabilization in conjunction with the digital one which allows you to take sharp pictures in the entire zoom range and at the very low shutter speed around 1/8 and even 1/4. The auto-focusing and optical image stabilization work in absolute silence, and the only zooming produces some soft "sh-sh-sh" noise. Good news - without any start/stop clicks on the footage 
.
DISPLAY: A large 3-inch high-resolution LCD monitor with 460K pixels has a very good contrast and saturation - the pictures look very "juicy". The brightness also is high enough to be seen even in a direct sun-light (just a bit darker) and in a wide angle of view. All that allows to share photos and videos immediately with other people.
MENU: For those who used the Panasonic P&S cameras before the ZS7 menu looks very familiar, just some new items added. Also there is a Quick-Menu button which is very helpful for a quick access to the most frequently used settings. The new camera has such a luxury as the Aperture, Shutter speed, and Manual modes and there is a new Exposure button (next to the video one) which allows to set manually the aperture using the Left-Right buttons and the shutter speed with Up-Down buttons.
AUTO SETTINGS: The best in the industry Panasonic's Intelligent Auto mode is getting better with each new model. Actually it's a whole bunch of sophisticated algorithms which help to take really nice pictures with minimum efforts. They are worth to be aware about so here is a brief list of most effective of them.
"Intelligent Scene Selector" - It quickly analyzes the light conditions as well as focusing results and selects either portrait, scenery, macro, night portrait or night scenery. It also displays a small icon of the chosen scene in the top left corner. The feature is extremely helpful when you need to shoot very fast on spur-of-the-moment.
"Intelligent ISO" - If camera detects that your subject is moving, it raises ISO and shutter speed to take shots without motion blur, otherwise it will try to keep the lowest possible ISO to reduce noise and to get nice clear pictures.
"Intelligent Exposure" - it's a kind of a small brother of the High Dynamic Range feature. If the camera sets the correct overall exposure but some areas happen to be too dark, this feature automatically increases the brightness of the dark areas to make the entire picture to look more balanced. It also pretty effective for the backlight conditions - instead of getting just a silhouette of your subject against the bright sky it makes the subject normally exposed but without washing out the nice blue sky.
"Face Detection" - is another great thing for taking good-quality pictures of people. It happened to me a number of times in the past that a presence in the frame of a more contrast element somewhere behind the person I'm taking picture of was making the camera to adjust focus at that unimportant distant object and therefore made the major person out-of-focus. The same way if there is a bright background behind the person then the camera will measure the luminance of that background while the person's image will be pretty much underexposed (dark). The Face Detection feature identifies the human faces and tells the camera to adjust focus and exposure for the faces first so the people on the picture will be looking well exposed, clear and sharp.
ADVANCED FEATURES: I guess the most interesting and advanced is a new "Intelligent Resolution" feature. Actually it combines a sophisticated noise reduction with a new picture enhancement algorithm. This feature automatically identifies the 3 type of the picture areas: outlines, detailed textures, and smooth gradation panes and provides an optimized handling for each of them separately. As a result the photo looks sharper at the edges and more clean in between. Many old P&S cameras had pretty fast picture quality degradation at the ISO around 300-400 and higher. The shots taken by ZS7 even at ISO 400 look pretty good on the small and even medium-size prints.
IMAGE QUALITY: Imagine on a sunny day you take an outdoors picture of a wall made of the new brown bricks with a $3000 DSLR and a small P&S camera from the distance about 6-8 feet. How could you recognize by which camera was taken a certain shot? The subject is plain so no Depth-of-Field is involved into comparison. However in this example the two characteristics will help to distinct the cameras: 1) The edges of bricks will be well outlined on DSLR shots and a kind of fuzzy on the P&S ones; 2) The new bricks do not have any structure on their sides, they are just plane and so exactly that way they will look on the DSLR shots, while on the P&S ones their sides will show more or less amount of noise. If you perform the same test for an evenly cut line of bushes (again DOF is not involved) you will see the same result plus the internal structure of each leaf will be more clear on the DSLR photos. So to make pictures taken with your P&S camera looking like the DSLR ones the P&S camera should make the outlines sharper, clean the noise on the plane or soft gradation areas, and slightly emphasize the internal structures, if any. That is exactly what the new "Intelligent Resolution" (IR) feature tries to do.
The "iAuto" mode in ZS7 is organized the way that you will have decent, good photos in virtually any situation right out-of-the-box. The several hundreds shots I took by now look good on my 24" display and so they will on the similar size prints. But if you look at them at 100% crop (magnification) then on many of them you might find some areas which do not look natural. If the IR-algorithm decides about a certain low-contrast part on your picture that it's a plane area then it will remove all the noise altogether with all the subtle details from that part of the picture. If you take a picture of a big tree with hundreds of branches (but without leaves) against a bright sky the IR-feature will treat it as a structured area and will slightly sharpen it to look clearer. But when you take a landscape picture with many distant trees in front and behind, those hundreds of crossing branches will create a low-contrast pattern which together with internal sensor's noise might look for IR-algorithm as just a noisy plain area and so it will obliterate all the details leaving only some average color in that part of the picture and so making it looking very unnatural. The thing is that unlike the previous models the noise reduction in ZS7 is pretty strong. I would not call it "aggressive" but it's really strong.

About the Author
What is the best way to chemically separate two optical isomers?
I am trying to find a currently used method, but any suggestions are welcomed. The optical isomers are of a metal complex. Thanks.
You would separate them using a chiral method. One good method is ELISA, which uses enzymes. Within naturally-occuring systems only one isomer will be attached to an enzyme, not both.
