Dpreview posted their very short A850 review (4 pages only). There is not much to say. Conclusions are very similar to the one written for the Sony A900.

P.S: You can order the Sony A850 using following links Amazon / Adorama / BHphoto / Amazon UK / Amazon Deutschland / Amazon France

One month ago in many forums people started to say that Sony could release the long expected firmware for the A850 and the A900. We didn’t hear anything form our sources so we posted the “rumor” with a low value “SR2=from unkown sources”.

What we post now is a rumor from one of our trusted sources. The Sony A850 and the Sony A900 will be released in March!

I really hope Sony has been able to address all the critics we read in the forums during the last months!

UPDATE: I have no details about the new firmware. I was only told that it will be a “major update”.

Digitalcamerarview just posted their latest Sony A850 test. If you read the pro and the cons list you will not find any surpise. The Sony A850 has an excellent resolution and dynamic range and has a not so exciting High-ISO performance.
