I recently got the Newer Tamron 15-30 Lens about half the price with the $100 rebate going on. This is a great lens with a lot of good reviews and 5 stars my favorite lens now on my D750.
Have had good luck with Lexar, I use to use San Disk I had a problem, they put me through to many hoops to get it replaced. They did, it was just a hassle. I Take a lot of sunset pictures every night and use the 128's in My D750
