Those of you who have read our exclusive Olympus E-400 digital SLR preview may have noticed that we mentioned something about an upcoming answer from Olympus on their current DSLR E-System top model, the Olympus E-1. At the last Olympus press meeting we had in Hamburg, Germany, where we were informed about the new line-up of Mju and FE-series of digital cameras and the 10 Megapixel Olympus E400 digital SLR model, we received the information that the Photokina visitor should not expect Olympus to showcase an extra digital SLR next to the new E-400 model. However, we have got official information from Olympus Japan that Olympus will have more to unveil at Photokina 2006…

Olympus digital SLR - FourThirds system
At the Photokina 2006, the world’s largest photographic and imaging equipment exhibition, Olympus will showcase their latest introductions of compact camera models and the brand new Olympus E-400 digital SLR camera. In addition, and this is the part where it is going to get interesting, "we will be exhibiting a concept model of the successor to our current Olympus E-System flagship, the Olympus E-1 digital SLR." At this moment we cannot give you more information, but we ca only say: "FourThirds system fans stay tuned, it will be worth it!"

Four Thirds system
Four Thirds is a reference to the size of the image sensor. The image sensor for Four Thirds cameras is what is commonly referred to as a 4/3 type or 4/3 type sensor. These describe the type of sensor not the actual size of the light sensitive area, which is normally much smaller. The sensor measures approximately 22.3mm diagonally, not four-thirds of an inch, which would be about 33.87mm. Traditionally, the nominal size of image-sensing devices has been based on a method of calculation that was introduced when vacuum image-sensing tubes were first invented. At the time, the outer diameter of these early 'vidicon' tubes was used to indicate their size. Unfortunately, this convention has remained despite the many advances in imaging technology that have since been made, and so the designation, "a four-thirds-inch sensor," can be a source of confusion. For this reason, many people now prefer to use the word "type" instead of "inch" when discussing the size of image sensors.

Olympus E-system - Standard
The Four Thirds standard has deliberately been designed as an open standard. That means the more body, lens and accessories manufacturers adopt the standard, the greater will be the degree of product compatibility. As a result, the range of equipment and options available to photographers will be all the greater.
