DSLR Pixel Wars Continue to 55 Megapixels
April 25th, 2012
Does the entry-level Nikon D3200 forecast the development of 55 megapixel SLRs? Yup, sure can!
The announcement of the D3200 gives an indication where the pixel wars are going next, now that image resolution is again in vogue. The 16 Megapixel D7000 with DX-Sensor dimensions of 23,6 x 15,6 mm enabled the release of the 36 megapixel D800 with FX-Sensor dimensions of 35,9 x 24,0 mm, both cameras having approximately the same sensor pixel density. The sensor area ratio of DX to FX is 2.3 (pixel density being the same), so 16 * 2.3 gives ~36.Enter the D3200 with 24.2 megapixels on a DX sensor, which translates into 24.2*2.3 = 55.6 megapixels. So an FX camera with the pixel density of the D3200 will be a 55 megapixel camera. Nice! Medium format is being seriously threatened. Nikon actually considering a release of such a camera will depend on how well the D800 is received. Too many photographers grouching about gigantic RAW files may delay release till demand grows.55 megapixels may be next
