Dear All! I did. I can't be more happy. My old dream came true, and ISO800 is perfectly useable for me. All of my lenses focus more sure and faster. I strongly believe that the CAM2000 is the very best AF module in a DX cam. I didn't feel the new 3500 as good. Damn my 180 AF-D became AF-S fast! Grip perfect for my hand. No built in flash, well... I'am forced to use my SB800 more often, never mind I can use my DK17M and DK19 again!!! Lovely viewfinder, easyer to focus my old 105 1.8 AI-S. I LOVE MY D2X!
