Hello all.
Just 2 days ago the Pentax Spanish Forum made an interesting review of the new K-7 and I wanted to share the results with you. Hopefully, you dont need to understand spanish because images speak by itself.
The idea was taking the same photo using a Pentax K-7, K20D, K10D, Nikon D300 and Canon 50D. As you will see there are different elements on the set so one can check dynamic range, color, IQ and noise at different ISO values.
All pictures were shot in RAW mode, auto WB, and noise reduction off. There is no post processing on any of them, just setting WB to Tungsten using Lightroom software, so NO noise reduction, NO sharpening, just export to jpeg.
The same lens was used on all cameras (different mount, of course) and it was a Sigma 105mm f2.8 Macro EX DG.
Here is the link:

* First test images are shots at ISO 100, no cropping.
* Then you have some 100% crops from 2 different parts of the photo at:
- 1/10, f:11, ISO 100 (except for D300 and 50D that due to a mistake on the test crops from these cameras are at 1/30, f 6.3)
- 1/20, f:11, ISO 200
- 1/40, f:11, ISO 400
- 1/80, f:11, ISO 800
- 1/160, f:11, ISO 1600
- 1/320, f:11, ISO 3200
- 1/640, f:11, ISO 6400
* Next post, there is a direct comparison K-7 vs K10D cropped and re-scaling the K-7 image to match the 10Mpx resolution of the K10D:

* Next post, same picture but without WB adjustment, just direct from cameras.
