Sony Full Frame Sensor

As you have probably all guessed by now I do like to take the odd photo and share them with the world, but when I read that Sony had released a 24MP Full Frame CMOS Image Sensor I started to salivate. I am sure that these sensors will find their way into Nikon and Canon Professional DSLR cameras withing this year… sure would be a sweet upgrade fro the current 10.3MP DSCR1 I currently use…

Sony Japan Press Release

Sony Develops 35mm full size CMOS Image Sensor with 24.81 Effective Megapixel resolution and extremely high signal conversion speed for use in Digital SLR Cameras All-pixel scan mode of 6.3 frame/s
Tokyo, Japan - Sony Corporation today announced the development of a 35mm full size (diagonal:43.3mm/Type 2.7) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the increasing requirement for rapid image capture and advanced picture quality within digital SLR cameras.
