From the Manufacturer
In developing the DMC-L1, Panasonic's aim was to create a digital SLR camera that delivers superb photographic rendering capabilities and is a pleasure to use.

The DMC-L1 comes equipped with a Leica D Vario-Elmarit lens that features the industry's first optical image stabilization system--MEGA O.I.S--designed specifically for the digital camera. The DMC-L1 also incorporates a Live MOS image sensor that conforms to the Four Thirds standard and offers 7.5 megapixels to ensure outstanding picture quality. The new camera introduces a full-time Live View function that, using a signal output directly from the Live MOS sensor, lets users see on the LCD screen the same image seen by the sensor. With full-time Live View and the DMC-L1's large LCD screen, users can compose shots in new ways and with greater ease and accuracy.

The L1's shutter-speed dial maintains the attractive look and feel of a film SLR.

The DMC-L1 also features a dust-reduction system that solves the digital SLR camera's long-standing problem of dust adhering to the sensor.

In the new DMC-L1, Panasonic has incorporated today's most advanced digital technologies while maintaining the attractive look and operating feel of the familiar film camera. A shutter speed dial on the camera top together with an aperture ring on the Leica D Vario-Elmarit 14-50mm/f2.8-3.5 lens give the user easy, intuitive control of the exposure. The magnesium-alloy body, which in design closely resembles the body of a rangefinder camera from days past, combines with the aluminium-alloy lens section to offer both high rigidity and a high-grade appearance.

A lens-based aperture ring provides intuitive camera control.

Complies with Four Thirds standard
The DMC-L1's lens mount system adopts the open format of the Four Thirds system, developed as a common standard for digital cameras. The Live MOS sensor it incorporates is a 4/3-type image sensor. This means that the DMC-L1 can be used with lenses made by a variety of manufacturers, giving users a host of equipment options. In the Four Thirds system, the lens diameter is larger than the image circle, making it possible to design the lens so that the light passes on a straight path to the image sensor. As a result, lenses for digital cameras can be created in a size smaller than those that complied with 35mm film SLR camera standards, meeting the needs of today's digital age.

在开发DMC-L1时，松下的目标是创造一个能够产生出超凡光学表现力的，并且富于使用乐趣的数码单反相机。

DMC-L1装配有Leica D Vario-Elmrit镜头，具有业界第一的光学图像稳定系统--MEGA O.I.S--其专门为数码相机设计。DMC-L1也结合了一个实时MOS图像传感器，对应于4:3的标准，提供7.5百万像素，以保证出众的图像质。这款新相机引入了一个全程实时取景功能，利用将信号直接从实时MOS传感器输出，让用户从LCD荧光屏上看到同从传感器看到的一样的图像。通过全程实时取景，以及DMC-L1的大LCD荧光屏，用户能够以新的方式轻松地精确地构图。

DMC-L1也具有减尘系统，解决了数码单反相机长期存在的灰尘吸附于传感器的功能。

在这个新的DMC-L1相机，松下结合了当今最先进的数码技术，同时保持了吸引人的外观和人们熟知的胶片相机的操作感。机顶的快门速度拨盘连同在Leica D Vario-Elmarit 14-50mm/f2.8-3.5镜头上的光圈环，给用户提供了简单而直观的曝光控制。其镁合金的机身，在设计上很相似于以往测距相机的机身，而组合以铝合金镜头部分，提供了高度的坚硬度和高级的外观。

遵守4:3标准
DMC-L1的镜头卡口系统采用4/3系统的开发为数码相机的共同标准的开放格式。其加进的实时MOS传感器是一个4/3-类型的图像传感器。这意味DMC-L1能够同多种厂家生产的镜头一起使用，给予用户许多设备选择。在4/3系统中，镜头直径比图像圈大，从而可能设计镜头使得光线以一条直路径通过而到达图像传感器。结果，数码相机的镜头能够被制作成一个小于那些适用于35毫米单反相机标准的镜头，满足今日数码时代的需要。
