Do they restrict "white lenses" or that sort of thing? Was in Egypt a couple of years back and one member of our group could not take photos 'cause the guards deemed his equipment was "professional" and he needed a government permit. He really only probably needed to bribe them (suspect their real motive) but I want to try to be relatively inconspicuous.
Not that I noticed, but strictly speaking they don't allow bags in there, but they generally do allow smaller bags. I had a ThinkTank Retrospective 20, a 1Ds MkIII and a 24-70 and had zero issues anywhere, however I no longer travel with three 2.8 zooms and multiple "backup" primes as, after a lot of trips, I realised I personally just didn't use them enough.
The Taj Mahal is the pinnacle, although the tripod rule is enforced in other places, I saw many people with two and three cameras, one Nikon guy I kept noticing had three, a D800 with a 14-24, a D4 with a 70-200 f2.8 and a Leica, all around his neck! Nobody batted an eye at that.
When I was last in Egypt, Israel and Jordan, 2006, I was still carrying three 2.8 zooms, and three 1 series bodies, two 1VHS's and a 1D, although I had heard of that "pro" issue I never encountered it, I shot extensively in the Sinai Peninsula, Southern Israel and Petra in Jordan.
