Pois, mas resta-me a dúvida: como se compararia com uma D800 normalizada a 24 MP?
i.e. a D800 beneficia mais com a normalização que a canon. (o que explica que vendo os valores nao normalizados as posiçoes se invertam - excepto em low ISO dynamic range, onde a nikon continua a levar uma clara vantagem).As can be seen, high-resolution sensors will gain more SNR, DR, TR and CS when reduced to a lower reference resolution. For DxOMark Sensor Overall Score and Metrics, we chose a reference resolution equal to 8 Megapixels, which is a bit less than a 12" x 8" print with a 300dpi printer. However, any other resolution can be chosen, as doing so only shifts the normalized values by a constant (because the reference resolution appears only as a logarithm in the formulas above).
What should be remembered is that doubling the resolution adds:
3dB to the normalized SNR
0.5 bit to the normalized DR
0.5 bit to the normalized TR
1.5 bit to the normalized CS.
creio que é possível normalizar ambas para 24mp com base nestes factores.
