Full Frame Shootout: A850 Vs D700 (Resolution and ISO etc.)

Seen this nice shootout report at a Taiwan forum with plenty of side-by-side sample crops and it would be very interesting to see how a 24MP Full Frame sensor is compared to the 12MP one, both made by Sony:-

(Text in Traditional Chinese, a Google Translated page can be found Here)

It seems that the A850 wins the D700 hands down at the low ISO with its much higher resolving power and the amount of details retained. As for the high ISOes, the tester/author says that the breakeven point is at ISO 800, which is already better than what I expected for the A850.

Enjoy measurbating! Pentax will possibly use the A850 sensor if they are going to make a Full Frame DSLR! I don't think they will use the D700 sensor anymore, unless Sony won't sell them the newer 24M one, or, they need to go really cheap.

i could see them using the cheaper older sensor and using their noise reduction magic...that was used with the kx. In the end Sony wins no matter what whehter people buy sony, pentax, or nikon...at the heart its all sony

And I do believe Pentax can do better than Sony if they are given the same Sony sensor!

Frank, it's my understanding the Kx has and had when released the LATEST Sony Exmor family chip wired under pixel's lenses (instead of between as the older type), so Pentax seems trying to use the latest, not an old stuff... It just depends on "if Nikon lets others buy the new chips" since they have a contract with Sony to sell them (Sony excluded) first the new sensors before to anyone else. Unfortunately our "small player" Pentax must wait to get the good stuff...

The D700 must be the best full frame camera because that's what Lance B would buy!!!! And as we all know Lance is never wrong.

Funny, I tested the D700 hands-on in the field back to 2008, now Lance has been "very impressed" with a D700 which has no battery in it ! :-o :-D

When I read Pentaxian forums, I don't see very often people dreaming of Sony Alpha 850 or Alpha 900. Nor much more about Canon 5D MarkII. But very much more often about Nikon D700. Because this sensor is stellar for High Sensitivity pictures, and has an icredible DR at low isos. So I don't know if it's cheaper than the overpixelled 24Mpxl Sony's sensor, but I think many people would be happy to have a FF Pentax with "only" 12Mpxls... ;-) I would be for sure!

NIKON DESIGNED & FABRICATES THE FF 12MP SENSOR. IT IS NOT MANUFACTURED BY SONY AND NIKON SOLD IT TO NO ONE ELSE!

SONY DESIGNED AND FABRICATED THE 24MP FF SENSOR. IT IS NOW DISCONTINUED. PENTAX WILL BE USING A DIFFERENT SENSOR.
