Hi guys. I did some research in November of last year and based on what I read on this board and what I wanted it to do, I ended up buying the SUNWAYFOTO XB-52 ball head. Specifically, I purchased it from Amazon from this listing:
https://www.amazon.com/gp/product/B007IVT794/
At first I was amazed. Coming from the tiny ballhead that came with my MeFoto Roadtrip tripod, this thing is a beast. But for the last few weeks I've noticed what I can only imagine is a defect ... or a very silly user error that I can't figure out.
If I tighten the ballhead hard enough that I think it's the right amount of tension to hold a big lens (biggest I used it with was the 800mm f/5.6L), then sometimes I can't loosen it back without significant effort or using a tool to beat it into submission (literally). If I don't tighten too much, it's not a problem, but then it doesn't have enough tension for even my 100-400II and 5DIV combo. For a ballhead with claimed load capacity of 132 lbs, that doesn't seem right. But it can't possibly be right that I can tighten it enough (without effort) to support that combination, but then need a hammer to beat the knob before it'll let me loosen it enough.
Am I missing something here? Is that a typical sign of failure? Is it something I did or am doing to damage it? Or is it a defect? I know it's not the top of the line ballhead, but at $320 it's not exactly a cheap one either...and it had glowing reviews here and on Amazon. So, what gives?
