Paid off is more like it. Ive never regarded his testing as legit.

Your scepticism is unwarranted. Do you mind sharing what makes you think this way? Asking because Bill's charts have always offered the most conservative DR scores, notably lower than manufacturers' claims or DxO tests. Basically the opposite of what a "paid off" lab would do.

And the recent revision is a warranted one, because combining outputs of a dual-gain system, while obsiously reduces noise and boosts DR, is not a form of algorithmic noise reduction which comes at the expense of detail. Therefore the A7V sensor does not deserve the "triangle penalty" in the charts. IMO Sony did a phenomenal job here and deserves a round of applause.


@A74me@@'s comment was not "scepticism", it was an accusation of unethical conduct. @A74me@ does not provide any evidence to support his accusation. The internet is full of such commentary, and, unfortunately, the FM forums are not immune.
