6 years ago i purchased my wife a nikon d-40. We are heading to disney in a few months and i was thinking of getting her a new camera for her birthday. She likes the d40 alot but i figured there has been some major improvements in cameras in the last six years. I see now you can shoot video which is really nice. Basically she shoot 90 percent of her pictures using the little dial with the different options landscape, portrait, action, and what ever else is on there. We bought the kit with the two different lenses and i know she does not like changing them out all the time. Been looking at the d5100 is it worth the upgrade for how she takes pictures? IF so is there a lens that i could get that would be good for all around shooting at disney. We are doing a bunch of character dining and she will want to take castle pics and stuff. Sorry i have no clue what im talking about. Turning to you guys for some help.
