So I may be missing something but I cannot think what it can be.
I have a Sony compact hx9v and an NEX-6. the 16mm on the NEX is very similar to the compact at its widest, so I thought I would compare the shots. With the bigger sensor I thought the NEX would produce a brighter picture.
Both 16 megapixels Both set to f3.5, ISO 100, 1/80, exp 0.
Even with this, the compact produces a brighter picture. I thought that with the bigger sensor the NEX would produce a brighter picture?
