Sony is showing some great technical innovation with the SLT cameras, but the A77 samples are disappointing at high ISO. In raw it looks like the A77 gives up a full stop to the Nikon D7000 and half a stop to Sony's own A35. Likely as a result, the A77 high ISO jpegs show loss of detail and look plastic. It is particularly surprising that the A35 images look better than those from the A77. Hopefully there is a fix in the works.
