It is astonishing to see that newbies buying their first DSLR (including me), even after spending so much time on their research, have hit on a sequence of spending behaviours that is not exactly helping them in the long run. Here is a rundown of half a dozen of such things they we regret on later.
1. Extra battery
The battery pack that comes with the camera is an excellent unit that lasts for a reasonable amount of shots. I have used my fully charged battery on Nikon D90 for approximately 600 shots on a span of a week. Although it would make sense to buy extra battery if you are into professional business, as a newbie you will seldom find yourself actually needing any unless you trek for weeks on end in the jungles.
