Before the Phillips chip all 35mm size sensors are made from multiple
smaller ones.

Subject: 24 X 36 Digital Image Sensors


I was just browsing Mamiya's web site and noticed that amongst the
numerous digital backs available for their 6X7 cameras, the two most
popular size of image sensors are 72 X 96 and 24 X 36; the 35 mm format.

If this size of digital image sensors are so readily available, offering
6.3 megapixals and a 12 F-stop dynamic range, why is there such a dearth
of 35 mm digital SLR camera's with 24 X 36 sensors, and such a
preponderance of cameras with smaller sensors that require a +1.5X
factor using standard 35 mm lenses.  I can see smaller sensors in ZLR's
 (camera's with non-interchangable zoom lenses), but if using a body
designed to use a manufactures existing line 35 mm lenses, then why not
offer 24 X 36 sensors?

Any thoughts?   Mike.
