D6 Shares A Lot!
The D6 shares a lot of accessories with the D5 and older bodies. Pictured above, the Really Right Stuff plates fit perfectly on the D6, so no need to buy a new one. The DK-2 Eyecup from the F3HP (my favorite eyecup) fits the D6 as well. You can use the battery from the D4 / D5 in the D6 and while this is might be tempting, I got a new spare EL-EN18c for the D6 because of the improved internal performance. And of course, all the SB-5000 wireless works perfectly with the D6 with no firmware or new accessories required. I know these are little things but I like little things, just less to think about acquiring to be operational now!
