Features
While the improved optical zoom may take centre stage, there have been many changes inside the TZ20. In fact, it has undergone something of an overhaul.
Rather than the CCD sensor used in the TZ10, the TZ20 has a CMOS sensor with 15.1 million pixels, of which up to 14.1 million are used for each image. This marks a two-million-effective-pixel increase, packed into the same 1/2.3in-size sensor.
As with the TZ10, different parts of the sensor are used depending on the aspect ratio, so the number of pixels employed relates directly to the aspect ration in use, be it 1:1, 3:2, 4:3 or 16:9.
Another key feature is the 3in, 460,000-dot screen, which now provides touch functionality. This adds another method of zoom, autofocus and shutter release control, as well as an intuitive way to view photos in playback mode.
The term ‘3D’ is one that we will become very familiar with this year, and this is especially the case with Panasonic cameras. A 3D shooting mode has been introduced on the TZ20 and a 3D image is achieved by holding down the shutter release and moving the camera from left to right as it takes several exposures.
This image is taken from a 14-exposure sequence achieved using the 40fps burst mode. In this mode images are at a reduced 5MP in size
There is a variety of frame rates available with differing levels of picture size and AF control during shooting, and they can be found easily in the quick menu. Up to 5fps is possible with continuous AF, and up to 10fps at full resolution. Burst modes of 40 and 60fps are an impressive feature for any camera system, although they come at a reduced image size. The new slow-motion video mode takes the number of scene modes to 30. In standard HD video mode, the TZ20 now offers 1080i recording, which is likely to please video users.
Other useful features inherited from the previous model include GPS, intelligent auto and PASM control. The TZ20 is a feature heavyweight and is likely to entertain both the novice and enthusiast photographer.
