You mean just A1 vs A2 for same camera? Both cameras seem to show relatively little difference outside.
I think that's what is expected; A2 is listed as "preserve warm tones", which to me means for incandescent it leaves it a bit warmer, but I would assume for daylight there should be little difference. Which is correct, right?
