Yes, there’s probably a shrub or tree next to her, but nevertheless when there’s even a hint of green in a skintone Nikons seem to pop it more strongly than Canons in a way that drives me nuts. But I’ve developed a work around that seems to handle it.
And as for the sunset shots on the Sigma 24-35, those extremely warm skin tones look natural because the viewer can see the color of the light behind them; the eye is used to that situation. So no it doesn’t bother me.
And finally, when shooting jpgs if i’m not using a custom white balance, I find I have to dial in about a half a unit of amber and a half of magenta to get skin tones looking decent.
But that’s just the way my rods and cones are calibrated, as always YMMV.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
