Blurry Fish Eye Lens Photos?

I got a fisheye lens and it was mighty expensive. Its a Japan optics HD digital advance 0.48x52mm. Im using it on my Nikon D3100 18-55mm lens and it never focusses. Ever. I've tried many things (auto/manual focus, 3D setting etc) but nothing seems to work. Are there any suggestions? It worked when the guy at the store demo'd it to me.

Which camera should I bring with me on my trip to Central/Eastern Europe?

Hi all, I'm going on a trip to Central/Eastern Europe in a few weeks, and I'm facing a dilemma over which camera I should bring. I have a Nikon D90 and a Nikon 1 S1. I'm not a professional photography, but it is an avid hobby of mine. I usually take photos with my iPhone. I want nice pictures for this trip but I also don't want to lug around and be so invested in being alert over the D90 that I won't be enjoying the trip. I havent practiced all too much with the D90, but I know enough to take OK pictures. I don't like the quality of the S1 very much, but it's easy to use and it's much lighter. This trip is one of those "once in a lifetime" trips. I want to make sure I have good pictures, but I don't want to have to compromise too much comfort for it. Thoughts?

Best/Cheap Lens for Nikon D800?

I'm going over my budget to get a Nikon D800 and it doesn't come with a lens either. I need a cheap lens for Senior Photos and wedding photos on the dance floor which means lower lighting on the dance floor. Also if know of any cheap monitors I can use for the camera that'd help out a lot. Thanks!

Cheaper alternative to Sony RX1? Compact camera that shoots quality videos?

I am looking for a nice compact camera that will shoot good quality videos. After doing some research I really like what the Sony RX1 has to offer, unfortunately it's quite pricey for me. The cheapest I've been able to find online is $2,110. I've also been looking at the Fujifilm XM1, which is more in my price range, but was curious what other options I might have. I've had a Nikon D3000 for quite some time but since I'll be moving to Italy in a few months I really want something more compact and that will take nice sharp videos.
