#17. "RE: D3100, D3200, D5000, D5100 Distortion Control Data Firmware Update" In response to In response to 16
Do you need this update. Well that's a matter of philosophy. See my post "#3" above where I discussed that general question. The short answer, as far as I'm concerned, is I put in the updates to my cameras.
Your D3200 likely doesn't have this updated Distortion Control Data Firmware, but you never know.
You should check your DCD firmware.
On your D3200, Press MENU to display the menus. Then go to the SETUP menu, then select Firmware version, and check the firmware. The latest DCD firmware is: L=1.006
If you're L is a lower version then I believe you should update it. There is no firmware update for your A/B firmware as of this date.
