D90 output soft

Shot with a D90 occasionally over the years. Always felt that in-camera processing cheated the high iso ratings on websites a bit, because the D90 produces softer images there that look as if they have been just noise reduced compared to D300 and D300S.

Conducting lens tests and checking for focusing differences on various bodies, noticed that the D90 files were much softer or mushy even in raw for the same lens focused correctly on a landscape scene, compared to the D300 this time. Yes, the noise is softened too, but the tradeoff was not good for landscape.

I read some odd comments such as the difference was mainly in the low-pass filter which could be more expensive than the sensor itself. Can anybody elaborate on this idea which is new to me?

The original dpreview recognises all this, just not as strongly as my own test:

"Unfortunately, for those people hoping that the D90 would effectively be a half-price D300, the RAW results appear consistent with those from the JPEGs. Although the underlying silicon is likely to be closely related, it's not necessarily safe to assume that it shares the D300's multi-channel read-out, or downstream processing componentry (Nikon's Expeed branding doesn't refer to a specific processor). Most importantly, there is nothing to suggest that the D90 shares the same low-pass filter assembly (which can be more expensive than the sensor itself and would be an obvious place to reduce costs for a camera in this price-bracket), which would explain the difference in per-pixel-sharpness we see here."
