next PZ lens test report: Olympus M.Zuiko 7-14mm f/2.8 Pro
#10
Quote:Well, therefore it is interesting to know how far was the testchart. And what does the sensor size have to do with the field cuvature? µFT just allows the manufacturer to use smaller lens elements that with 35 mm, for instance.
The test chart is at around 51x the focal length distance. For 7mm that means around 7 x 51 = 35,7mm distance.

 

There are no test images at f2.8 or f4 or even f5.6, so no way to tell if the corners will be that badly affected at more normal UWA distances, or how ones photography would be impacted?
