If you're looking at natural light, you'll want a camera that rates well in the low light/ high ISO category to protect you in various shooting environments. Based on low light/ high ISO alone,. the Nikon DF comes out tops according to DXO Mark with the D3s second but over all best is the D800e. There's also the D610 nestled in there with good scores for color depth. Keep in mind if you choose the D800e you'll want a computer that can handle such high megapixels. It's a lot of money to drop. I suggest you go with the essentials first and then use your remaining money after you determine what your needs are. For example: D800e - $3,200 (can buy used for less) 85mm 1.8 -$500 24mm 1.4 - $1,900 70-200mm - $2,400 5-n-1 Reflector - $50 Batteries, grip, memory cards - $1,000 Total: $9,050 Or you could substitute the D800e for the DF which will save you hundreds of dollars on computer upgrades and storage drives.
