Jim, you stated for some of the images in this thread that you used raw (DNG). Please confirm that you used raw for all, and what you used for white balance (auto settings?) I would suggest that you use a fixed same white balance for both images per pair.

My general observations without knowing the white balance used and assuming any adjustments related to brightness were the same is that the newer lens is perhaps slightly brighter.

However, differences in white balance sort of spoil the comparison, as sometimes one is bluer than the other and sometimes the same lens is less blue, perhaps depending on slight differences in framing.

I would try to set each to a constant white balance as to colour temperature and tint if possible, and if not would try a manual white balance using one of the lenses with the same manual white balance setting used for the other lens.

Regards, GordonBGood
