(in Chinese)

Someone at the Chinese Xitek forum hinted that he had tested the beta unit of the FF and told the following:

1. The new machine is not 42MP.

2. The AF speed is very high.

3. There are many AF points than ever.

4. SR Super-resolution mode now works handheld.

5. The result of the handheld super-resolution mode is good and it works!

6. Overall better experience than the D810.

Photo Rumors said the New Pentax FF Will Use the Old 36M Sony Sensor
