Why would Panasonic want to spend £x,000 on sponsoring any other peoples filters?Probably not, but the type of cameras they are giving the people on the programme to use are able to have filters attached.
They don't have to mention a 'brand' of filter, but maybe the 'type' of filter would have been a good idea. Instead of 'like sunglasses'. What solid colour sunglasses or graduated colour sunglasses? :bonk:
I'd wager that was the reason none were mentioned. My wife thinks as they mentioned sun glasses the filter was a polarising one.
