A 1:1 Sensor Is Possible For 4/3

Lloyd Chambers, over at Diglloyd, has posted an analysis of the image circle of Micro 4/3 lenses and found that they are huge. Most of the lenses could cover an APS-C sensor

That doesn't really tell us anything, though. We would need analysis of the degradation of the image, and I suspect that it would be pretty extreme on an APS-C sensor. What excites me about this is the prospect of a 1:1 sensor, which would be completely and absolutely unique in the camera world. I don't think there are even any 1:1 medium format sensors being made.

A 1:1 m4/3 sensor would have a diagonal of about 24.46mm. The smallest image circle was the Panasonic 45mm f/2.8 at 25mm, which just squeaks by. Basically, a 1:1 image circle is compatible with every lens he tested, even the cheap ones.

Considering that this sensor, if implemented, would be in pro-oriented product, the possible confusion associated with degraded image quality at the corners wouldn't need to be much addressed. Pros and enthusiasts understand the principles underlying photography and know quite well what the 1:1 ratio would entail.

I again express my absolute support for this sensor in the upcoming Olympus E-7. It needs a unique calling card. In a market with cameras like the NEX-7, X Pro 1, and full-frame cameras costing below $2,000, any Oly offering that costs in the $1,500 area would die a quick and inauspicious death.
