Is that a photo of Max Load, the comedian?
New to photography, I set out to test a couple of tripod/ballhead combinations and couldn't find any standard test. So, I made up my own test by setting the camera to the maximum magnification Live View and then noting the displacement when a weight was hung from the lens, and then the amount and duration of vibration when the lens was given a sharp knock.
Nothing remarkable came out of my tests but it did get me thinking about how people gravitate towards the most expensive equipment and how lighter weight tripods and smoother ballheads account for much of the cost, whereas stability seems to almost be a secondary consideration. In fact, I'm surprised by the number of photographers who are enamored by tripods/ballheads but don't give much consideration to shooting technique and/or improvised stabilizers like bean bags or string tripods. And I'm surprised that nobody seems to be concerned with how grips might affect tripod stability. The extra height and additional attachment must make a difference.
If you can come up with a standardized testing method, it would be interesting to have other POTN forum members all perform the tests on their equipment and share their results. I'd do it!
I would think any kind "max load" testing will end up damage the ballhead. so don't do it on your own ballhead!
there are two reasons triggered my question when i was looking for a ballhead in the market. If I have no constrains on budget and weight, i will just go for the most famous brand (read: expensive), and the largest ballhead (read:heavy). Unfortunately that is not the case for me, and I believe that will not be the case for most of us.
if you look at ballhead product line (regardless the brand), you will see the bigger the diameter, the higher "max load", and the higher "price tag", and the higher "weight".
I need one for travel purpose. I want it to be light and hold more, and price lower. So where should I go?
36mm will be lighter than 44mm than 55mm , in general, and cheaper, and lighter. I also noticed most of 36mm ballheads have the "max load" that at least 10 times of the weight of my equipment (my heaviest combination is 5D MARK II + 70 200MM F4, 760g+950g = 1710g based on Canon data, ignore the plate as it is usually around or less than 50g if it is not a L plate).
i would be happy to go for 36mm ballhead but then, if you read enough, you will see people usually suggest a 44mm ballhead for that kind of combination.
That let me suspect there is a sort of standard for "max load". and, if you look through the numbers, they are quite close. for example,
Markins Q10, 44mm, 45kg
Photo Clam 44ns, 44mm, 50kg
Sunwayfoto XB44, 44mm, 40kg
should i read it as a coincidence? or there is a sort of "standard" at somewhere...
