A Bright Zoom
The lens is the same as on the E-10, so the maximum aperture is still f/2-2.4. On the other hand, as the sensor has changed, the focal lengths are slightly different, now being 9-36mm, i.e., a 4x, equivalent in 35mm to 35-140mm. It still has threading for mounting 62 mm filters. The camera comes with a lens hood, which clips on the end of the lens and is mounted the other way round when the camera is in its case.
As we already said, the E-20 stores its photos in a buffer before transferring them to memory. If you use JPEG, you can take a shot-by-shot sequence of up to four photos in about five or six seconds. Beyond four, you have to wait for the cache to empty. The idea was a good one, but it would have been better if the cache were bigger. Four photos is not a lot!
This camera is just as quick to boot. Another good point is that its autofocus is the fastest of the four. It takes barely a second to focus, as opposed to twice the time for the DSC-F707 and time and a half for both the Coolpix 5000 and the Dimage 7. There is no square framing the subject - the image is either clear, or it is not.
