The DSC-T1 has a resolution of 5 Megapixels. With which Sony sets the tone again. In spite of the emphasis on design the resolution has not become less important. The image size can be set through a quick button on the back of the camera. This button gives access to a number of resolution settings: 5M (2592x1944), 3.2 (2592x1728), 3M (2048x1536), 1M (1280x960) en VGA (640x480). There is also the possibility to choose from two different sorts of compression: Fine and Standard. The T1 camera has three different ways of setting the automatic focus. The Single AF (S AF) is meant for daily plain objects. Focussing takes place at the moment the release button is pushed halfway down. The S AF setting is the standard setting of the camera. Second way of focussing is Monitoring AF. The camera already starts focussing before the release button is pushed. The moment the release button is pushed halfway down and the AF lock is carried out, the focus is set. Third and last option is a Continue AF. The camera focuses before the release button is pushed halfway down, the AF lock is carried out, however, the focus is not definitely set. The focus system will still search for the ideal focus. This option is suitable for shooting action pictures.
Beside the way of focussing one can also choose the focus frame. There can be made a choice between three sorts of focus frames: Multipoint, Centre and Spot AF. The Multipoint uses five focus points, Centre puts the emphasis on the centre of the image and Spot only uses a small detail in the middle of the image to focus. The DSC-T1 has an extra option to manually set the focus distance (0.5, 1, 3, 7m and infinite). The camera also has two exposure methods: matrix metering (multipattern) and spot metering.
The DSC-T1 camera is equipped with a built-in optical zoom. The lens is a Carl Zeis Vario-Tessar lens with a brightness of f3.5-f4.4 and a focus range of 39-114mm equivalent to a 35mm camera. The lens zooms in, in about 20 steps. Beside the optical zoom the T1 camera also has a so-called Smart Zoom function. This zoom is related to the set image resolution, so it won't zoom in anymore if it is damaging the image quality. In other words, if the camera is set to a resolution of 3 Megapixels (which is the maximum resolution at the Smart Zoom function), the digital zoom works up to 3.8x digital but at a resolution of 640x480, 12x digital zoom is possible. Standard the zoom is set to a resolution of 5 Megapixels. The normal focus distance is 50cm, the Macro function shortens this distance to approximately 8cm (wide angle). There is another possibility to shorten the distance, but I will tell you later on. When the camera is used in bad light circumstances when there isn't sufficient light to focus, the built-in AF assistant illuminator can help to focus correctly.
The camera has a built-in flash with a maximum range of approximately 1.5 meters, regardless the setting of the zoom. The flash has a number of settings like: Auto flash, fill in flash, flash with slow shutter speed, red-eye reduction and flash off. Standard the camera is set fully automatically. Beside the standard setting for the flash the operating of the camera is also based on a fully automatic operation. It is still possible to automatically give priority to a certain exposure, also when the camera is operating fully automatically, by activating one of the scene functions. Via the menu one can choose from 8 different scenes and beside that the P-function and Auto function. Well known scenes are available, like landscape, twilight, portrait, beach, fireworks and snow. I would like to highlight one of these functions: the magnifying function. This function enables to get as close as 1cm to an object, with an extra option to zoom in 2x, a magnifying factor of 3.3x, very impressive!
Other features of the DSC-T1 are: exposure compensation, histogram before taking a picture, bracketing, adjustable white balance, flash compensation, adjustable ISO value (auto, 100 200, 400), continuous shooting, digital effects, contrast, brightness and colour saturation adjustments and various image editing functions like resize and crop functions.
Beside the possibility of capturing high resolution still images, the DSC-T1 camera also has a high quality video clip function. The camera has three settings: 160x112, 640x480 and 640x480 in Fine compression and a speed of 30 images per second. One who wants to use the last setting will have to use a Memory Stick PRO Duo memory card while the standard Memory Stick Duo card can't take this influx of data in good time.
