Is there any chance that you were shooting beyond the available light (Blinking display)? ISO 1600-3200 may not have been adequate if you were shooting f/8-f/11 at any kind of shutter speed in fading light. (I have little feel for how bright the field lighting is in the fabled Vale of Narellan.)
It is also possible that there may be a fault with the lens such that does not stop down properly. Try this:
- Camera on tripod pointed at a well-lit blank wall
- Av mode
- Fixed ISO
- Matrix or center-weight metering
- Shield viewfinder opening (thumb or cover included with camera) to avoid biasing the meter with light from the rear
Make a series of exposures (one for each aperture setting) and compare the preview images in group view. The images for each should have equivalent brightness. Alternatively you can take the meter completely out of the picture and do the same test in M-mode adjusting the shutter speed manually to agree with the aperture.
One question...Is the 100-400 lens NEW or used and new to you?
