Damn right I do - Mk6 Kevlar and ECBA (old style with the small plates).
The new ECBA rubs like hell and everyone I know who patrols on foot prefers the old stuff - in Sangin the Paras took thiers off at the HLS and went in sans armour completely as they were going down with heat injuries. I kept mine on and went through 6 litres of water in 2 hours. Not good.
No real probs using cameras with the lid on, I've found. Just make sure all the straps are done right. I must be one of the few blokes around who remember the Mk6 being introduced - we were give 2 40-minute lessons on how to adjust the straps. Blokes just get the helmet thrown at them now and told to get on with it. Maybe why I see so many people's helmets flopping about with dodgy straps...
With regard bylines and crediting of images - all publications are supposed to put my name and CROWN COPYRIGHT, but since we give the images free to all the news agencies, by the time stuff gets to the papers, you often only see the Agency byline appear. Important thing is that I know it's mine and if I spot it, I can clip it for future use.
All the Agencies know who I am and the quality of my images, so that side of things isn't going to be a drama when I leave the army.
