I'm a relatively new landscape photographer and long-time user of a tripod with quick-release plastic clasps on the legs (I've owned this specific tripod base for around 10 years).
On a recent trip, I spent some time at landscape photography hotspots, where I had a chance to meet and chat with other photographers at scenes. While it didn't come up in conversation at the time, I noticed that most of the other photographers (essentially, all of them) used twist-action tripod legs -- the common older design where leg segments are released or locked in place using a screw threaded lengthwise along the leg.
Is there a reason this kind of leg release action is so popular among (at least) landscape photographers? Is it more robust against harsh environments, or less prone to e.g. locking up after a dip in a cold river (which was a problem that did affect my quick-release clamps after ice formed up on them)?
All I'm sure of is that they have the drawback of being slower to set up.
