Pentax 645z sensor best sensor ever tested at Dxomark

You might want to try to understand what Dxo does first, before you talk about body colors, digital filters, autofocus or any other camera features which are completely irrelevant for this general sensor ranking.

And it's not a shame to use the second best or third best sensor, especially knowing they are cropped x1.3 sensors compared to the 645z.

These small sensor cameras from SoCaNikon will never really be able to compete with MF if there is no weird technology fumble by the sensor maker (Sony in that case). Simple physics.

You just get local exceptions as the max dynamic range of a D810 is especially good or the max dynamic range of the A7RII is especially poor (below D7200 APSC level!).

The 645z sensor now is leading the sensor pack for 1,7 years as the king of the hill. That's quite good.

My discussion was not about DxO. It was about the analogy of calling the 645Z a high performance Spitfire/Zero airplane and other cameras a slow Sopwith Camel airplane. And I suggested that as the tempo of taking pictures becomes faster, the better image quality will come from a sports-like cameras more so than a slow 645Z that is not as well equipped for fast picture taking.

i'm not sure where the confusion in this thread about camera performance is coming from? because the graphed data is pretty clear, you pay a lot more for a 645z, and you don't gain much dr over ff at all... ff sensors are utilizing more modern technology, and no, the d810 dr is not better than a7rii dr.

"The D810 has better base ISO read noise and EDR.
The cameras are neck and neck at ISO 100.
At ISO 640, the a7RII pulls ahead and stays ahead."
