Panasonic Lumix DMC-TZ3

Manual Control Options
As with most point-and-shoots, the Panasonic Lumix TZ3 offers manual control of white balance, ISO sensitivity, metering, and AF settings. However, the camera does not offer control over shutter speed or aperture like higher-end compacts or SLRs.

Focus
Auto Focus (7.5)
Users have a fair amount of control over the auto focus system. With both single and continuous focus, users can switch between five settings: spot focusing, 1-area focus, 1-area high speed, 3-area, and 9-area. The camera is capable of focusing normally at 1.64 feet and beyond. Zoomed in, the camera can accurately focus at 6.56 feet to infinity or 1.96 feet to infinity when zoomed out.

The camera also offers a Macro focus mode, located on the top mode dial, for close up photos. With a focal range of 3.28 inches to infinity in telephoto macro mode, the camera effectively captures details at close range.

In practice, the TZ3's auto focus system worked well in wide, normal, and macro shooting. The camera handled low light and low contrast scenes effectively, and was able to track moving subjects well in ample lighting.   

Manual Focus (0.0)
Like the majority of point-and-shoots, this 10x optical zoom camera does not provide a manual focus setting. This is unfortunate since the TZ3's large screen would offer an ideal focusing window. 

Exposure (7.25)
The Panasonic TZ3 offers basic exposure control. It has a standard exposure compensation range of +/- 2 in 1/3 steps. With live preview, even beginners will be able to identify the exposure modes. As a safety net, there is also a bracketing option that takes 3 frames in succession at +/- 1 in 1/3 steps.

Like the lack of manual focus, the camera does not possess manual exposure or aperture or shutter priority modes.

Metering (7.25)
The Panasonic Lumix TZ3 offers a well-rounded metering system. The metering options are multi-pattern, center-weighted, and spot at 1, 3, or 9 points. 

White Balance (7.0)
The Lumix camera offers a strange mix of white balance options. It has the basics - Auto, Daylight, Cloudy, and Shade - but leaves out a fluorescent setting, a key setting that most point-and-shoots offer. Despite its lack of a fluorescent mode, the auto white balance still produced decent results under fluorescent lights.

The camera does offer a few advanced features. Uses can view white balance functions with the live preview without having to set it. The TZ3 also allows users to set white balance manually.

ISO (7.25)
One of the TZ3’s biggest upgrades is its new Intelligent ISO system. Marked by the "I" icon on the mode dial, the Intelligent ISO system detects motion and sets the ISO and shutter speed accordingly, making the function ideal in fast-paced situations such as shooting sports or trying to capture running kids. With Intelligent ISO, the camera can focus at 0.16 feet from the subject in Macro or at 6.56 feet in Telephoto mode. There is a limit of ISO 400, 800, or 1250 when using the Intelligent ISO system.

Other ISO options are Auto (at 200 ISO), 100, 200, 400, 800, and 1250 at full resolution, a higher sensitivity setting that comes with the updated Venus Engine III processor. The TZ1’s ISO topped out at 800 (in auto mode), making the TZ3 more flexible in low-light. 

Shutter Speed (0.0)
The Panasonic TZ3 has automatic and manual shutter speed controls. Users can manually select from the following preset slow shutter options in the main menu: 1/8, 1/4, 1/2, and 1 second. For automatic settings, the camera has a range of 8 to 1/2000 of a second or longer exposure settings of 15, 30, or 60 seconds in Starry Sky Mode. Like most self timer settings, the shutter speed is set for either 2 or 10 seconds, enough time for the photographer to jump into a group photo.

Aperture (0.0)
The Lumix TZ3 selects the aperture automatically. In wide shooting, the camera captures at f/3.3 – 8.0 (in 2 steps), allowing enough light to pass for accurate exposures at ISO 400 or more. In telephoto, however, the camera captures a limited f/4.9 – 11.0 (in 2 steps) that might have users boosting ISO sensitivity to compensate.
