Nikon and Sony may use 25MP APS-C sensor
Both Sony's future Alpha camera and by extension the rumored Nikon D400 could use a dramatically improved crop frame sensor whose resolution would enter medium format territory. Sony DSLR trainer Michael Bubolo said he had heard "rumors" the APS-C sensor on the Sony camerawould jump to 25 megapixels. While this detail wasn't as definite, Bubolo told Amateur Photographer it was certain the camera would use a new sensor, as its ISO light sensitivity would range into the "hundreds of thousands," a category previously occupied only by high-end, full frame cameras like the Nikon D3s and Canon EOS-1D Mark IV.
Other reportedly certain details for Sony included a new electronic viewfinder and a durable magnesium body. Sony had already pledged itself to using the translucent mirror technology first shown in the A33 and A55 but with much improved performance inside. One previous rumor had made similar claims.
For Sony, it would most likely replace the Alpha A700, which hasn't been updated since 2007. It would not only improve image quality but speed up the focus speed by letting the camera 'see' the subject through the mirror and ready for the next shot much sooner than on conventional DSLRs.
Nikon won't necessarily use the sensor, but it has historically relied on Sony for much of its technology, especially with high-end cameras such as the D3x. The company would most likely use the 25MP sensor to replace the D300s with a D400 or an equivalent, since its most advanced crop frame camera hasn't been given any update since 2009 and was originally unveiled with its current 12-megapixel sensor in 2007.
When it would ship other than 2011 isn't known, but it might arrive at the CliQ 2011 expo, previously known as PMA, on September 6.
