I have had great results on auto and sport as I am mainly photographing birds. A hint you will loose focus if you zoom in to close, also when you make your first click wait for the green border to make sure your in focus with the right object. I am totally satisfied with the great results and clarity I get...I am putting together my photos into a book.
Hope this helps
Probably. I have noticed this camera drop in price dramatically and it is being updated. I don't know what your problem is but I returned mine when it would not take a pny brand memory card. Was told by Nikon tech it only uses a sandisk brand and that nikons are this way even if I bought another. I also had issues with a wireless card in this camera but that may have been the card as much as the camera. Otherwise, it is a good basic camera but I am moving up to a canon t4i so I can do more and have flexibility with add ons, cards, etc.
It took me a little longer to get mine, because I ordered the red one that is pictured. They had to contact me to let me know they only had black ones. So, just order black and you'll get it really fast.
I'm really surprised at how well the camera does at low lighted events. I usually take both flash pics and no flash pics but find many times the pics taken with available light are better than with the flash. Hope that helps.
It includes 1 battery, 1 battery charger, strap, lens cap,user manual and CD with software. You need to buy a SD or SDHC memory card. I recommed this http://www.amazon.com/gp/product/B007M51J42/ref=sr_1_3?ie=UTF8&keywords=sandisk%2016gb%2030m%2Fs&qid=1355418604&s=electronics&sr=1-3
Also recommend a screen protector like this http://www.amazon.com/Polaroid-Protective-Coolpix-S1100PJ-S1200PJ/dp/B007MDFN50/ref=sr_1_6?s=electronics&ie=UTF8&qid=1355418917&sr=1-6&keywords=screen+protector+p510
I'm not for certain..I just started reading the manual to learn the features. Under the continuous shooting it talks about just holding the shutter release down all the way..... I haven't had time to dig deep into it but if I can figure it out, I'll definitely share with you! Sorry :(
