Necessary evil for D700
on December 27, 2012
One of the reason I bought my D700 was to get that 8fps. For those who dont' know this, that's possible only through using either EN-EL4A battery(preferred) OR by using High power AA alkaline. Taking the EN-EL4A route would cost you extra. You would need
1) This Nikon BL-3 battery chamber cover(costs around $35)
2) EN-EL4A battery(New ones cost around $110. You can buy used in eBay for lesser)
3) MH-21/MH-22 charger which can charge your EN-EL4A battery(New ones cost around $120, you can buy used in eBay for cheaper)
You should consider your shooting style and other factors before deciding whether you would want to take the AA battery route or not.
Anyway if you choose the EN-EL4A route, this piece works great. The EN-EL4A battery fits snugly inside you MB-D10 grip and with this setup you are ready to shoot for a longer period of time.
