Just test the E-1 again at center weight average and A mode, with brighter
scene (ISO200, F4, 1/250s), both 35/2 and 75-150 (at 75mm) got brighter
image at F16 vs F4. When the target light was lower (ISO 200, F4, 1/13s),
the images was slightly dimmer at F16 for 75-150 and the 35/2 still gives
slightly brighter image at F16. It looks more complicated as I have
expected, I didn't know it is light intensity related although I knew
different lenses act differently.
