Nikon D3100 Sensor Size
The Nikon D3100 advertises having a DX-format sensor like it's other non-FX sensor models.
One thing I've noted however is that the sensor size according to Nikon's site is 23.1 x 15.4 mm rather than 23.6 x 15.8 mm with every other DX camera.
I'm aware this isn't a SIGNIFICANT difference however it does give the camera a different crop factor.
Does anyone know, is this correct or is Nikon's specification inaccurate?
