Thanks for doing the comparison.
The E-5 photos show that they tried to get back to the E-1 look with some success. It's only the E-3 that seems to have trouble with the pinkish cast.
I'd probably turn down the saturation on the E-5 since the E-1 is generally a bit much at times and the E-5 is way past that level.
I agree with you on that. The E5 seems to oversaturate on its default settings.
