Sony Alpha DSLR-A550 review
Using kit lens image quality is only 3.5. With Tamron 18-250 or Minolta lens image quality is almost 5. Very good relation between cost and quality (only body).
It is much better then A380 and A350.
You can set individual settings of matrix.
With Tamron or Minolta lens the image quality is compareable with Nikon D90.
Don't use kit lens!!!
