Reichman: Sigma's only hope, bundle it with their least bad lenses
In article

It's not in any useful sense a 45MP camera; resolution measurements on previous Foveon-based cameras make this very clear. very true. A 15MP non-Bayer camera should show somewhat increased resolution (as measured by actually photographing things and seeing what you can resolve in the resulting images), especially color resolution, compared to a 15MP Bayer camera; but nothing like 3x. nothing like 2x either. where the difference lies is the aliasing and sharpening added in the raw converter. in other words, it's fake detail. |
