Can I bring my Nikon Cool Pics into a Justin Bieber concert?

This week im going to see Justin Bieber and saw in the rules that the lense must be smaller then 3cm to be able to bring in, the lense is smaller then 3cm but its still a fairly big thick camera. Would I be able to bring it into the concert? This is what the camera looks like! http://digital-photography-school.com/wp-content/uploads/2009/02/nikon-coolpix-p90.jpg

Nikon Coolpix L310 - Filters, and Reviews?

Http://www.ephotozine.com/article/nikon-coolpix-l310-digital-camera-review-19389

^ Thats the camera I'm talking about.
If you have this camera, can you tell me about the perks? Other than just the basic stuff? Favorite scenes/modes for indoor/outdoor use? close ups? stuff like that…

Also, is there any filters that fit this camera? I know, its not an slr, so they wouldnt be advanced filters… but what size/ 55mm? i think 67 but not too sure…

Any opinions on these filters?

Reviews on FujiFilm FinePix 4250?

Im looking into getting a new camera and I had a few options.My first pick was the Nikon L810 (which I havent heard very great things about), Second my friend offered to borrow me a Fuji S5000, third I have found a new camera Im interested in and have read some good reviews. Its the FujiFilm FinePix S4250 24x Optical Zoom Digital Camera. If anyone has any useful information about any of these camers please let me know. Thank you.

This will be used as a started camera for my photography business.
Added (1). As I said this will be a STARTER camera, to see if this business even takes off. I realize that I will need a better camera which I do intend to buy. But at this moment I do not want to spend thousands of dollars, I just want to get a nice camera to start out and see how it goes.

Samsung nx1000 photo quality.?

I purchased the samsung nx1000 and I used the smart auto mode. Took a picture, it looks amazing on the 3 inch LCD screen but once i upload it to facebook, it doesnt look stunning anymore it's like the photo is so dull the colors are not striking at all compared to when i view it on the camera itself so I feel like i've been cheated.Is it only the smart auto mode? or its better with other modes such as Manual? Does anyone think Nikon P500 can take much more decent photos than this?
