As an update to my original query about compact tripods...
On Friday evening I decided to go for it and purchase myself a RedSnapper quat tripod with the RSH-12 ball-head mount. It arrived first thing this morning.
I haven't used it "in the field" yet but have toyed around with it in the house, getting used to the weight and feel of it. I must say I'm impressed with it so far, its strongly built and durable, I've had my A350 + 50-500mm "Bigma" mounted on it with no issues which means it can easily handle anything else that I have. It also comes in its own bag with a shoulder strap for easy carrying. Not half bad I think!
Thanks for all the help with this one, I'm really pleased with this purchase. Now just to put it to its first real test!
Best regards
Gavin
