I have never had the TSA security get excited about my camera gear, they only seem to worry about my computer, iPad, and having too many "layers" of electronics that the x-ray couldn't clearly see through. If you get a "CheckPoint Friendly" carry-on bag (shoulder, backpack, or roller are available) which will unfold to expose the computer section clearly, you should have no problem going through security. Or, remove your laptop and iPad as expected, but then you have to keep track of all the pieces until you are able to collect them together again.
Of course ... individual TSA agents may make unexpected requests of you which you should probably submit to, even if the printed TSA regulations say differently!
I use a small "Skooba CheckThrough" roller carry-on which will fit under the seat. It unzips to unfold for x-ray. I removed the center divider in the main section of the bag so that I can either put a camera insert in it, or simply put my smaller walk-around camera bag loaded with my camera and lenses (Billingham Hadley Pro or Hadley Small usually) inside along with other small stuff like chargers, cables, gps, etc. It will even hold a Think Tank "Urban Disguise 40" bag inside, but that pretty much fills the main compartment, and my computer goes in the fold-out computer compartment which also has a see-through window for visual inspection of the computer within.
