very thanks
so, about you,
this is NOT a real problem if there are different exposures for different apertures?
the lens is good?
please see here:
i did now a new test ("shoot with the light behind you")
(Jpeg, Aperture-Priority; exposure multi-segment; AF in center; 100 iso)
For me, the question is, how does my equipment as a system perform. Normally +/- less than 1/2 stop over the entire exposure range of the lens is not critical. If you find it critical, then you can bracket automatcally. Each photo on it's own (in your first set) would be called suitable, hence there is not really an issue.
For what ever reason, I could not open all the photos in the second set, and you should consider resizing them, if you are posting only for information only on something like exposure, but the real issue is that you need to do exposure tests on a uniformly lit surface that occupies the entire frame.
I looked at the first and last photos, and they are not identical in composition.
With the camera on multi segment, and a variable image, it is impossible to tell exactly what the camera is thinking. and even a slight change in composition can have a big impact on the end result.
