Which sensor will Pentax 645D use?
At that point it is not clear which sensor will be deployed in the upcoming Pentax 645D medium format camera. My first guess few months ago was for the KAF-39000 from Kodak.
The only problem is that neither of those sensors will give us the reported "1.7 times bigger than a regular full frame sensor" ratio (official information from Pentax).
- A regular full frame sensor is 36mm x 24mm, or 864 mm² with 43.3mm in diagonal.
- The older medium format KAF-39000 sensor is 49mm x 36.8mm, or 1803mm² with 61.3mm in diagonal.
- The new medium format KAF-40000 sensor is 45.76mm x 35.34mm, or 1617 mm² with 54.78mm in diagonal.
