There are some features that are identical, but then there are 3 major differences between the Panasonic Lumix DMC-ZS1 and DMC-ZS3.
First let's take a look at the features that are similar that help these two cameras stand apart from the digital compact camera crowd.
Panasonic Lumix Dmc Zs3
10.1 megapixel image sensor
Leica Lens with 25-400mm Optical Zoom - this is an amazing range, especially with the extremely high image quality ratings enjoyed by both cameras
ISO of 80-1600 (expandable to 6400 with high sensitivity) or auto
Fantastic image quality
iA (Intelligent Auto) Mode - includes Face Detection, Subject Detection, AF (auto focus) Tracking, Scene Detection (Intelligent Scene Selector), Light Detection (Intelligent Exposure and Auto Backlight Compensation)
One note about the ISO range of compact digital cameras - most compacts are notorious for the amount of digital noise at higher ISO settings, and the Panasonic line of compact digital cameras is no different. However, Panasonic is making advances in this area of technology so that the noise level is less than other cameras of similar price and features.
