Here we are comparing two cameras with different body types: Panasonic ZS1, which was introduced in May 2009 is a Small Sensor Superzoom camera with a 10.0MP 1/2.5-inch sensor whereas Ricoh GXR GR Lens A12 28mm F2.5, which was introduced in September 2010 is a Advanced Mirrorless camera with a 12.0MP APS-C sensor. There is 16 months difference between ZS1 and GXR GR Lens A12 28mm F2.5 so we don't expect to see a huge technology difference between these two cameras but it would still give an advantage to younger GXR GR Lens A12 28mm F2.5, especially in sensor tech.
Comparing an interchangeble lens camera to a fixed lens camera is a bit tricky but we will do our best to make this a fair comparison.
Here is a brief look at the main features of Panasonic ZS1 and Ricoh GXR GR Lens A12 28mm F2.5 before getting into our more detailed comparison.
Let's read on the following sections in order to better understand in detail how Panasonic ZS1 and Ricoh GXR GR Lens A12 28mm F2.5 compares and hopefully end up with enough arguments to decide which one is better for you.
