I think you should sell.
The grip is too ex and lack of the vertical dial which is very useful. Very troublesome if you need to horizontal to dial exposure then back to vertical to shoot..unless fix setting.
The cable will be there, you need to live with it.
Maybe you can think of it as value for money, since grip is really big imo. Too big to be comfortable for my use.
But it is just me..... :devil:
Greedy leh...in Nikon camp but still drooling for km/alpha
