I have a Nikon d3100 with kit lens. Have had it for 3 years. No scratches, looks very new and clean because I barely used it.

I want this camera for multiple reasons. & i've asked people for a good camera and most of them said this one. So can someone explain it all to me? I want to know about different lenses i can get for better quality and such. & hopefully you can dumb it down for me to understand. I'm sorry, i've done lots and lots of research but i don't understand any of it. Thank you so much. Also, if this isn't a VERY GOOD camera what other one should i get?

Why did my long exposure (star trails) photo come up with all of this noise?

I took this star trails photo: (go ahead and enlarge it) and it came up with a bunch of red and green noise. I've never had any problems like this before, just on my new Canon t4i. I've shot star trails for this long (long exposure, about 2-3 hours, ISO 100, large aperture) on my old Nikon D5100 and never got any sort of noise. I shoot regularly on this camera and even do other long exposures for shorter amounts of time but never get and noise.No, there was no big light behind me or anything, all light was natural. I've shot in the middle of the woods and had the same problem. Any suggestions?

Added (1). Correction: never get any noise*

Would this lens autofocus on my Nikon d5100?

This is my first DSLR and I'm still learning. I just realized that the camera will only autofocus with AF-S and AF-I lenses… Will this Sigma 28-200 3.5/5.6 Macro Compact-nkaf autofocus on my camera?

Added (1). I'm a poor college student so I'm trying to get the cheapest zoom lens (28-200mm) that I can possibly find. Any help or suggestions would be appreciated.

Added (2). Would not having AF really be that awful?

Added (3). Thank you, thank you, thank you! This is perfect! I really appreciate your help!
