Easing into FX from DX, crop modes, etc
I would like to move to the FX world from DX (D90) with a D610. I understand that the 610 will go automatically into "DX mode" when a DX lens is mounted on the 610. I fully understand the "crop" that will occur and I presume this will be the view seen in the viewfinder and in live view so that framing will be apparent. I have a couple of nice FX lenses, the Nikon 60mm f/2.8 macro and the older 80-200 f/2.8 ED lens. But I have some other DX only lenses such as the 35 f/1.8, and a Sigma 18-250 f/3.5-5.6 which is the walk around lens on my D90. The 24-85 is packaged with the 610 at a good "kit" price but I really want the 24-70 f/2.8, which could take me a long way into this FX adventure. Of course that is about $1300 more than the "kit" 24-85.
Any thoughts from DX to FX users easing into the transition using crop mode?
I have the money now so I would like to get the FX camera. Landscapes, macro & portraits. Not a speed shooter or video shooter. Print my own 13x19s with my trusty Epson R1800.
Thanks in advance for any thoughts you might care to share.
