Thanks for the responses. I am glad that there's no difference in color for the Sigma and Nikon 35s.
The kit consisted of D810, 14-24/2.8, 24-70/2.8G, and 70-200/4. I first bought from B&H, ran out of time to exchange, so I had to return entire kit. Then bought from Adorama so they were running same sale. Problems included uneven resistance in the zoom ring twice (14-24) and sharp, or smooth zoom ring and slightly unsharp, decentering (24-70), soft center/corner to f8 (24-70), sharp at f5.6 and not sharp at f8 (70-200), on and on... In hindsight, I should have kept the first sample of 24-70, but wasn't expecting that much field of curvature intrinsic to the lens design.
I've been pixel peeping since Thanksgiving and hope to never look at a photo at 100% ever again! Tests were done on two D810 bodies. Fortunately, my dealers are the best in the business for this kind of situation. My current samples of the 14-24 and 70-200/4 are excellent. For aerial photographs center/corner sharpness is critical and that's why I went with a high MP camera system, otherwise I've been a Canon shooter for 35+ years. I might even consider using my Canon 5D and a 24-105/4 (sharp sample), and Nikon for 14-24 and 70-200.
As for the 24-70, I'd be happy if I could get a excellent center and very good corners. But, the 24-35 end seems worse than the 50-70 end for this lens.
I finally made a plate and tilted ruler assembly to check for back/front focus issues for any new lens from now on. I wasn't doing this earlier since I never had to do it on my 5D1. So much for technology... The 14-24 and 70-200 focus well. Besides, how does one fine tune focus for a zoom lens? What if there are focus differences at 24mm vs 70mm?...
