Hi thanks for the responses.
I'm the anorak too and try and take a photo of everything I fly on. All my photographs are usually taken using an iPhone so it's not too much hassle to pull it out whilst walking up to the aircraft, pausing for a second to take a picture. However in the past at Southampton and BHX I've had ground crew give me the stare of death for pausing to take a photo.
Anyway next week I'm flying out of BFS and wanted to bring my DSLR and test out my new fisheye lens. I really don't want to get yelled at cause it would be extremely embarrassing .
