Just curious. I purchased a couple of Lexar 32 GB cards for the D-600. I read in the manual (needless to say, after I purchased the cards) that the "tested and approved" Lexar cards only go up to 16 GB. Are there any issues with the 32GB cards? (Lexar Professional 400x 32GB SDHC UHS-I Flash Memory Card LSD32GCTBNA400). Thanks for your help.
