Olympus Digital SLR Cameras
One thing's for sure about the Olympus digital SLR cameras: they're ground-breaking.
What follows is a list of "firsts" associated with the Olympus digital SLR line:
- First to adopt the 4/3 system (see below)
- First to include dust-resistant sensors
- First to include live-view LCD screens
With dust control and live view nailed down, the only missing feature from these cameras was image stabilization. Well, that's certainly not true anymore.
The Four Thirds System
All Olympus digital SLR cameras use what's called a Four Thirds system, and this describes both the sensor (it is neither a CCD nor a CMOS sensor) as well as the connection from camera to lens (called the lens mount).
What's the big deal about this?
First, it is an attempt to move away from a lot of specialized digital SLR lenses toward a standard.
Today, if you get a Canon camera and a lens to go with it, that lens won't work with your Nikon camera. You've got to buy a separate lens for it.
But with the Four Thirds system, any digital camera that follows the standard can use any Four Thirds lens.
This means that you can use the same Four Thirds lens on digital SLR cameras made by different manufacturers. For example, you could take your Four Thirds lens and attach it to either an Olympus or a Panasonic camera since they both follow the standard.
The Four Thirds sensor is smaller than other digital SLR sensors, which provides two advantages:
- The camera is very quiet because of a smaller mirror in front of the sensor.
- Four Thirds lenses are smaller and lighter because they don't have to light up a huge surface area. The 4/3 sensor is about half the size of a 35mm negative. While this doesn't mean that 4/3 lenses are half the size and weight of regular lenses, it helps.
Drawbacks of the Four Thirds System
Adopting a new standard never comes without a few drawbacks, and there are certainly some to be aware of before you buy an Olympus digital SLR:
- Old Olympus lenses aren't 100% compatible - since the Four Thirds system uses a new mounting system, old Zuiko lenses won't attach directly to the camera. If you have old Olympus lenses, you'll need to get a MF-1 OM Adaptor, which limits the functionality of the lens (e.g. manual focus only).
- There aren't many lenses - all of the Four Thirds lenses have to be developed brand new for any camera that uses the 4/3 system. While the number of new Four Thirds lenses grows constantly, there aren't quite as many to choose from as there are for cameras made by Canon, Nikon and Pentax.
- The standard may not be adopted - it's anybody's guess whether or not Four Thirds is here to stay. If other camera makers don't buy into it, then there's not much advantage to a standardized system of lenses.
The E-330 and Live Preview
In 2006, Olympus announced the follow-up to their EVOLT E-300 digital SLR, and the new camera was a first.
The EVOLT E-330 was the first digital SLR camera to display a live preview of the image you are about to take on the LCD.
While this functionality is common on compact digital cameras, it is not on digital SLRs.
Digital SLR cameras use mirrors to reflect the image captured byt the lens up to the viewfinder. This system of mirrors (called a pentaprism) poses a technical challenge when it comes to the live LCD preview.
The E-330 leaped this technical hurdle and is not only the first Olympus digital SLR with live preview, but the first from any manufacturer.
