Hi,

I didn't really get the stuff with 100% more light reaching the sensor.

Erik,

On the DXOmark dynamic range page, the highest DR rating for the D3 (11.92EV) is shown at the camera's lowest and actual ISO of 161. The highest DR rating for the D3X (12.84EV) is shown at the camera's lowest and actual ISO of 78. The difference in exposure between ISO 161 and ISO 78 is approximately one stop.

LOL, then what is an "over the average" lens in the Nikon world, among the wide ones?

I was just pulling Ray's leg, it is of course the best wide available, at least on the wider end.

Now on the 24mm end, I find the 24mm T/S to be a bit better, but I have not done any rigorous comparisons.

Cheers,
Bernard

Please list your excellent lenses! I thought the 14-24 was outstanding? was thinking of getting one to replace my Canon 17-40L

Marc,

Sorry, I was just joking. The 14-24 is obviously the best wide in Nikon's line up.

Obviously though, normal lenses/short teles still feature a higher level of image quality. The lenses I consider to be the sharpest in my line up are:

- Nikkor AF-S 60mm macro at f7.1
- Nikkor AF-D 85 mm f1.4 at f5.6
- Zeiss ZF 100mm f2.0 at f5.6

In wides, I find the 24mm T/S to be a bit better than both the 14-24 f2.8 and 24-70 f2.8.

Cheers,
Bernard

Ok, this sounds better. On the other hand, your remaks about the usability of the focal length range is serious. I am a Canonite, but no fanboy by any means, and if I could justify it, I would think about a D700, instead of the 5D2, simple because of the better lenses (screw my six Canon lenses :-).

Re the T/S lens: how the flaring and CA? I am using very often Canon's best wide zoom, the 17-55mm IS (APS-C dedicated), but it's CA is atrocious. The vignetting too is very bad for panos, but that can be corrected generally, depending on the focal length and aperture. However, I have to try around with each frame with the CA correction parametes, and often I can correct it only partially (ACR sux, but otherwise it is better).
