Third party AF-S lens for Nikon?
I've been buying Nikon lenses for my D5100. Now, I want to move on to other manufacturers. I'm worried about the Auto-focus motor. How do I make sure that the Tamron or Sigma i'm buying will have an auto-focus motor in the lens? Thanks.
Added (1). More details:
I happened to pick one of my friend's Tamron, and the focus motor did not work on my D5100.
Would be great if you guys can also give me info on how to figure out about the Image stabilization or Vibration reduction terms used by these third party manufacturers.

This is going to be my first photography "job" and I seriously don't know what to do, I'm fourteen and I will be taking pictures of my Uncle, Aunt, and their two children.
I have no idea what the area we'll be at looks like, I obviously can't get up and go drive to it, I'm only fourteen! I'm glad they trust me, but I'm nervous, I've never taken actual photos, I mean I have but they weren't planned out and it was just a family day at the beach type thing. I just took pictures of the children playing in the sand and water, nothing "professional"
Can someone possibly help, I have a Nikon d5100 that I recently bought over the summer hoping to do stuff like this for the family, but I really wished that my family went out first so I knew it was okay if I messed up(if you know what I mean)
I'm worried the most about positions;
Do I tell them how to sit?
What if they're not sitting correctly?
Do I touch them and make it correct? (it's kind of awkward)
How do I position them?
What positions?
Standing, sitting?
ect, ect, ect…
I'm also worried about how the area looks, the only thing I know about this place, is that they've got this small little chapel across the street.
If anyone could help and tell me what you do at a photo shoot.
What it's like to be a photographer.
Photography is what I want to do when I get older,
but I don't think I'm ready. I'd much rather like to have had practice first.
The only I could really do now is show the chapel, which is this;
credit goes to the photographer.

Finding a Tripod with a Landscape Mount?
I don't understand.Shouldn't most tripods sell landscape mounts (so you can mount your dslr vertically instead of horizontally)? I have a very cheap tripod right now, but I will get another soon. And I want it to have this feature, because not having it is very frustrating.
So any suggestions of models would be helpful.
