Nikon D5100 with AF NIKKOR 50mm f/1.8D for Portrait Photography?
I want to buy a lens for portrait photography and was thinking to get a 50mm prime. Is it a good idea to get a D lens? What possible problems can occur? I know this lens won't auto focus on my camera.

Is there a good alternative for Nikkor AFS VR zoom?
My wife has a Nikon D3100, and she wants a zoom lens (70-300mm) for her birthday. From the research I've been doing, the top of the line choice appears to be the Nikkor AFS VR 4.5-5.66 IF-ED. The best price I've seen so far is just under $600.It seems that a lot of people like Sigma lenses for their Nikon SLRs. Does anyone know of a Sigma (or other brand) equivalent for this lens?

Nikon D3100 Wireless tethering shooting to Mac?
I was wondering how I can shoot photos in my studio & have them wirelessly upload them (& display them on screen for client) to my mac. If there's a usb cord that's fine & also what program would be recommended?

Basically i bought a sunpak power zoom 4000af flash for my nikon d3100 camera. But I have NO clue how to work it! I've put the batteries on, turned it on, and thats it. I've NO clue what to do or even how to test the flash. I don't know how to set it up with my camera either.
Pretty desperate here! It never came with instructions, so please, Help!

I accidentally dropped my lens and for about a week whenever I tried to attach the lens, I would get a message on the camera that said "No lens attached". After messing around with the lens, I found the problem and I can now use the camera. The problem is it isn't adjusting to exposure or auto focusing anymore. I only dropped the lens not the whole camera. Any ideas for how to fix it? I let a friend mess with the camera some too and I don't know what settings they changed. Do I need to get a new lens or send it back to Nikon? Please help. Thanks.
Added (1). I've only had the camera and lens for about 3 or 4 months. This is the first time that it's ever been dropped. I don't have a warranty on it because a relative had gotten it for me and they didn't get the warranty. I do still have all of the papers in the original box, people have told me that they thought there was a limited warranty somewhere in there that you could sign up for online?
