However, some vendor like Induro doesn't even provide that information. all i have is "max load" ...

I emailed Induro about ball diameter a while back. "1" series is 36mm and "2" series is 44mm.

I have an Induro BHL1 and love it. Probably would have like the BHL2 even more.

RRS have great comments on what ballhead is suitable for what gear : http://reallyrightstuf​f.com/WebsiteInfo.aspx​?fc=72 (external link)

At least this comment is way more informative then a max load based on a finger in the air. But its not comparing with other brands.

thanks for the information - it appears the selection are about how big the lens is using and how big/heavy the tripod is. make sense to me. i was guessing (at least within the same product line) the bigger the ball, the heavier it can hold.

so it appears max load is a useless marketing pitch, and will not be helpful if used in cross-brand comparing...

maybe i should take my question one step back, and think of what are the objective indicators other than price then? or is there any indicator other than "they are sturdy, they are fantastic, you get what you paid for...":confused:

Hi Thanks for the information. Induro was in my long list but because I could not find this information i decided to not consider it.

this is very helpful. Thanks!

thanks Vince. all the ballhead i am looking at, are compatible with arca swiss standard.

i am trying to find a way to decide which brand and which model I should go with. I looked at ball size, max load, height, weight...it appears now i have no clue as there is no objective standard other than "looks good, feels good".

everybody says "the more expensive, the better". in general I agree with that statement, but...money is always an issue, isn't it? :o

You just have to narrow it down one step at a time. Go with load capacity first then ball size. That should cut out at least half of the options.

Everyone recommends their favorites or what they are currently using, but there is more than one good brand. As long as you choose from the many reputable brands out there, you shouldn't have any problems.

So, since the number cant be trusted, go with whats tried and true. Go with what many others use and was has not failed them. Thats pretty much how I have always done it. Specs can be the second criteria in line.

Thanks for everybody's input. I feel I should report back to the forum just to share my selection process. I hope it will be helpful for others regardless my decision is right or wrong.

I got the impression that the bigger the ball, the smoother and easier to adjust when use. so I narrowed down to 44mm ball heads. I was comparing Markins Q10, Photo Clam PC-44NS, Sunwayfoto XB-44 and DB-44.

I ended up purchased sunwayfoto DB-44.

From price perspective Q10 > PC-44NS >= XB-44 > DB-44. (I am in Canada, the price in the US and Canada are slightly different)

Load capacity perspective (yea now I know this number means nothing), PC-44NS > Markins Q10 > XB-44 > DB-44.

User feedback perspective, Markins is way ahead, followed by Photo Clam; sunwayfoto is not a famous brand in here. but I read the sunwayfoto discussion in the largest photography forum in China. Several senior members there who also owns Markins or RRS actually bought it and highly recommended it.

Funny enough, my finally decision on DB-44 was made based on something not so related.

1) sunwayfoto are made all metal (yes, the screw knot is metal finish no silicone). I somehow like all-metal stuff.
2) they have dealer in Canada and make the price as the same number as in the US.

I am still waiting for my Feisol 3401 to come. the dealer in Canada is running out of stock.

So, this will be my poor man's super comb. it's not the fantastic combination of Gitzo tripod + Markins ball head + RRS clamp. I will see how my combination works out when I am traveling in California this July.

Thanks again for everyone's input!

I'm also looking to upgrade...or lack of a better term "Throw away my Manfrotto" and also in Canada, can you share the dealer that carries the Sunwayfoto?

Thanks

It's a good question :) interesting enough i could not find their Canadian dealer either but then it was actually on their website.

I am not sure if it is appropriate to provide this kind of information on forum. However if you google "sunwayfoto canada distributor", you will find it. the dealer is in QC. they charged me 8 dollars for delivery to Toronto, with tracking number, arrived in two days.

I need to do the same. Tired of the big sag, forcing me to aim high before locking head.

Ok I found the dealer in QC thanks, however this ball head is a little more than I want to spend, I think I will go the Vanguard SBH-300 route, it gets good reviews and over $120 less. Since in the last week I have bought a Canon 60d 18-135 kit, a 50mm 1.8, and a 70-200 f/4 USM, if I spend any more big dollars my wife will have a fit, and I still want to pickup a 430EX II.

Hi for the flash, 580ex II is on sale at $399 in Canada. You probably want to check that out.

Markins' rating of 100 lbs is probably with the ball stem perfectly vertical with the weight perfectly distributed on top of that. That, to me, is not a realistic rating. The only way a ball head couldn't handle the weight in that manner is if it was made of weak materials or poorly designed. However, all of these top of the line $400 ball heads are made of aluminum.

I wish these manufactures would put up some realistic ratings. That will never happen though, since a lot of buyers look at specs. The one with the highest numbers looks like it's the best.

One thing I found helpful is Markins' rating of both weight and torque, and the combination of these two numbers telegraphs their measurement/rating system. Let us accept Markin's own spec sheet that both of the following to be true at the same time (this is for the Q20):

max weight=110lbs
max torque= 220 inch pounds

now Then the measurement has to be made by hanging 110 lbs at 2-inches away from ball center. I imagine this is the absolute maximum torque that the ball can tolerate without either slipping or becoming damaged. not realistic at all, but it does give you a clue as to how to determine the real capability. Hats off to Markins for at least revealing this.

now then, the distance from the clamp itself to the ball center is approximately 2", but mount a real lens on there and you quickly see that 110 lb capacity disappear. for example, my 70-200 f/2.8 produces 5" of distance from lens center to ball center. This configuration would only support 44 lbs of camera+lens. 44 lbs times 5 inches = 220 pound inches.

so put a larger lens on there and measure lens center to ball center. divide 220 inch-pounds by this distance and you will have the absolute maximum weight of gear that the ball will tolerate.

400mm on a 1.6x body is still 400mm. sensors do not change lens physics...

One warning; the first Vanguard SBH-300 I received felt pretty good but not perfect. I sent it back for a replacement and the second one was much better. You probably won't have a problem but I'd recommend ordering from somewhere that has good customer service and a reasonable return policy. Amazon paid shipping both ways and had the replacement delivered the very next day.


Replacing my Canon 7D, Tokina 12-24mm, Canon 17-55mm, Sigma 30mm f/1.4, 85mm f/1.4, and 150-500mm with a Panasonic Lumix FZ1000. I still have the 17-55 and the 30 available for sale.
