Went up twice. Though the second time was more about sharing the cold I picked up on the first visit as I could not concentrate much on work. Never bother taking kit myself, though plenty walking around with great big rucksacks full of gear.
For me it is more about touching base with suppliers to see new ranges I can bring in. That said I did succumb to a set of the new Bowen flash units and a 35mm Sigma art lens so not the cheapest days out! Did just about resist the canon 5D Mk IV....for now.
Didn't buy a monitor as originally thought, couldn't get a much better price than any other time. Saw a few good reductions on Canon flash, bodies, lenses with most offering double cash back but I don't really need another body just yet anyway. So all I bought was a £12 Tenba camera body wrap!
I think sometimes they shoot themselves in the foot by pushing too much gear in front of people. I couls really do with another camera bag for example but there were so many on display by those specialising that I simply gave up trying. I could have spent the whole day on one stall trying to work out which of a hundred odd backpacks, shoulder bags or wheeled boxes would suit me best.
Went today and parted with more money than I had planned... picked up a nice new tripod, Manfrotto camera slider, speedlite diffuser and sensor cleaning kit (as I fancied giving it a go for the first time). I now have a completely dust free sensor, so no trips to the camera shop required.
I also note a rather appalling drone demonstration near the food area - the pilot managed to entangle the drone in the netting, managed to shake it loose but failed to catch it as it smashed into three pieces on the floor.
