TPAM syempre CF kung me pera
For those who has questions regarding kung kaya nito or kaya niyan you can always consult the manuals of the individual items you plan to put on your tripod or google them for their weight...add add lang yan.
Here's the thing.
1) Una dapat alam mo max load ng tripod legs mo
2) Pangalawa dapat alam mo max load ng tripod head mo
These are two different things don't rely on the "general" max load which is usually the one you see on ads for tripods kasi me times they are misleading and good tripods usually costs a sum so mistakes can be costly. Misleading kasi minsan yung max load ng legs yung nilalagay nila dun sa ads kasi malimit malaki yung max load talaga ng legs when in reality the head's max load is the limiter of the setup.
The idea is the legs should be able to support the load+the weight of your head.
The head's max load should also match or be less the max load of the legs. Any more then the setup will not be efficient since you really can't load more than the legs' max load without sacrificing stability so its best to limit the head's capacity to match your legs' and not go over it. Again if you have money or by luck you got a better head than your legs it is still not advised to load over the legs capacity.
For weight considerations, it is best to buy a tripod+head which can handle your heaviest setup. Just add up all the weight+head and according to some site add a little bit extra from around 15% to 50% (recommended by thom hogan yung 50% more) more and that should be your ideal max load.
-I saw on a website Benro A-1695 + BH0 combo. In the website it says the max load is 8kg. But upon researching the 8kg is the max load of the legs while BH0 head also being sold separately only has 4kg max load. From this I can already say that the "real" max load of the setup is 4kg since the head limits the legs' max load. Sure enough, when I bought one the tag with the tripod and the box indicated the 4kg limit. So be careful with this so that you can plan correctly when buying one. In the future, I could just upgrade the head to one that has a max load of 8kg to maximize this setup.
-My heaviest setup would look like this D90+battery grip+SB-600 flash+50-150mm lens. According to the websites and google their approximate weights are 700g+400g+400g+700g = 2200g roughly. Add 15-50% it would fall to some what 2530 - 3300g. Which is why I got a head that can carry around 4kg. For the legs, same computation as above 2200g+head weight which is 230g for a total of 2430g. Add 15-50% should be 2795 - 3645g. The legs I bought can carry 8kg so this should also work for me.
Again you can always brace the tripod or shorten the length or add extra weight at the base but these are the "somewhat" ideals in trying to compute for a good tripod for your setup.
Hope this helps.
