As has already been stated, this isn't a huge hassle. Just take your camera out of the bag or sign up for PreCheck or Global Entry.
What I've found more painful is the increased security on flights to the US. We traveled from Morocco via Madrid/Heathrow four months ago and the Heathrow experience was the usual. A few days ago we traveled again through Heathrow (from Johannesburg) to the US and several steps were added to the usual security.
- A new line where all passengers flying to the US must undergo a short interview. In our case, she spent most of her time questioning our kids. I noticed foreign passengers were asked detailed question about their jobs and reasons for traveling to the US. The major pain here was the understaffing - it took about 45 minutes to get through the line.
- At the gate they then checked our passports (another long line), then the final line involved a guy with a list. In our case, he just checked our passports again and waived us forward, but I noticed other passengers had to remove everything from their carry ons for inspection.
We had 2 1/2 hours between flights and it was barely enough.
Once we arrived in the US, entry procedures were unchanged and moved quickly.
