Re: How Olympus Tricked Me, and why I let it go.

Please define "telecentric" to us dumb folk

It means the rays of light leave the lens running nearly parallel to eachother, hitting the sensor perpendicularly.  That way, light will have no problem reaching the bottom of each photon-well, even in the corners of the sensor.

Back when the Four Thirds standard was developed, this was important because it resulted in a uniformly lit sensor. Legacy systems like those by Canon and Nikon, with their designed-for-film lenses, suffered from vignetting, in particular with wide angle lenses.

Telecentricity became more or less irrelevant thanks to improved micro lenses (a layer of miniscule lenses on the sensor) that funnel and direct the light into the photon wells.
