p.3 #3 · The BEST Carbon Fiber Tripod


John,

That's an excellent find addressing Gitzo versus Benro and also the crazy Benro rumors.

My degree is in metallurgical engineering and material science. One thing that stood out to me as a questionable item is the piece about casting. Poured gravity casting is also capable of developing voids. A key issue in reducing voids can be the design of the mold and the very shape of the object. It would seem that Gitzo has designed these very well as I've never heard of a cast component failure in a Gitzo, but to claim that gravity casting alone eliminates air pockets and anomalies, I wouldn't buy that argument. I have actually done some casting as well as a number of other manufacturing methods in the laboratory.

In my opinion, if Gitzo wanted to create the strongest and lightest possible spider, they would choose a forging process and then machine finish the part. Forging processes generally result in higher final strength and a very low probability of voids and other impurities. It also often results in a lower part weight, but the cost is much higher than a casting. If Gitzo were manufacturing a forged crown and none of their competitors were, then I would feel there was a compelling reason to support their price premium. I think we might also see the weight drop by another 1/4 to 1/2 pound.

I don't know the process used to form the legs on Velbon, Giottos, Manfrotto and Slik tripods, but I agree with the posting. A drawn of mandrel, extruded or pultrusion methods will normally yield a stronger tube than any type of seam construction. There is also the other point. How much strength is needed to support a camera. I think it is clear that in MOST cases it is the locks, not the tubes that are the weak point. Does it really matter that a tube has a 1000 psi strength or a 100000 psi strength when all it is supporting is a 5 pound camera and the leg lock can only sustain a 15 pound force?

The idea that carbon must be woven to achieve strength is also something I find odd. Woven fiber composites can have strength, but they can also have weak planes. People recognize the look of woven carbon fiber because this is how it was first introduced to the market. It was used like fiberglass, laid out on the form and slathered in epoxy. But now many composites are created with the fiber inserted into the plastic in a random fashion and then injected into the mold or form providing plenty of strength and ideally, no weak planes and no voids. People don't recognize this as carbon fiber, so these parts are sometimes covered with a final woven layer. The carbon weaving can be as much about marketing as it is about the technology.

As for price, there are always going to be those who pay more for quality. Gitzo is not a brand everyone can afford. It never will be.

This right here tells me that there is a marketing component to Gitzo's pricing. They intend to sell their goods as a prestige line and don't intend to compete on price. That's totally within their right to do so and I have no problem with it. People buy BMWs and Mercedes when a Volkswagen would likely accomplish the same task. But I believe it means that you are paying a premium for their brand and the perception of quality that goes with it (on top of the increased cost for the manufacturing process). I buy a tripod as a tool to use, not a status symbol. I can afford a Gitzo or two, but if a less expensive model will meet my needs with minor compromises, I can use that money saved for other purposes. If it were major compromises, I don't think this would apply.

Again, I have no doubt that Gitzo makes the very best carbon fiber tripods on the market, but I do have to question whether it is worth the price premium.

"I think it is clear that in MOST cases it is the locks, not the tubes that are the weak point."

Stability vs carrying capacity and the ability to dampen vibration vs support capacity vs final weight of the product. A tripod is a cascading chain of events, not just what's in a leg.

"As for price, there are always going to be those who pay more for quality. Gitzo is not a brand everyone can afford. It never will be."

"This right here tells me that there is a marketing component to Gitzo's pricing. They intend to sell their goods as a prestige line and don't intend to compete on price."

No it doesn't. Quality costs and not everybody can afford the freight. One can't expect a product line to be everything to everybody for a give away price and still expect the company to turn a profit. See it in the same light as hiring (paying for) the services of a "metallurgical engineering and material science." I'd be willing to bet, those who know their stuff are in higher demand (better paid) than those who are only marginally competent.

Your above sounds like someone saying that they can get the same quality at K-Mart and then not be expected to take the time to qualify the overarching statement. What price is quality worth to one, will be different than what price quality is worth to another vs what one is able to afford vs what one is willing to shell out.

"..but I do have to question whether it is worth the price premium."

What about us who are happy to pony up the price?

There's a reason that Gitzo has a target on their back.

Gitzo, what all the rest of the manufactures wish they could be.

There's Gitzo, and then there's everybody else.

When you buy a Gitzo, you know you've bought the best.

The only question that seems to arise when shopping for a Gitzo, is the price, not the quality.

Hmmmmm!

A several points -

1. It is not a question of supporting the camera - even the cheapies won't collapse under the weight. It is all about dampening vibration. In point of fact, in some article I have some where, Gitzo even says that their tripods will hold the mass of the average American male without failing. So, I would expect, that Gitzo has done the R&D to determine the best fiber layup and tube design to promote vibration damping.

I can confirm that Gitzo has done a good job on vibration damping when I did some tripod testing a while ago. In that test, even if I jumped up and down as hard as I could alongside the tripod sitting on a hard wood floor, there was very little impact in the image that I could see. In other words - the legs did an excellent job of damping the vibration.

2. Pricing - No body is doing cost based pricing anymore on pretty much anything except pure commodity products (zero differentiation) and cost and pricing are very much decoupled except for the fact that if you can't make it except to lose money, you stop making it fairly quickly. Also, the cost of a product (cost of goods sold) does not account at all for the R&D expense that is usually one of the major costs. This is where many of the Asian knockoffs copy the design, don't do the R&D and get lower cost because they didn't do the work. They also miss the subtle differences that matter in performance and reliability because they don't truly understand the IP. These are the cases where they have problems with adhesives, with castings that crack, leg locks that need tape to take up slop in the threads etc... They do get the fit and finish right but miss some/most of the other important but less obvious stuff - looks great but has other hidden problems. (I don't like hidden problems.)

Other costs come in to play like replacement parts available for long periods of time etc... Reliability is in this category too.

So, your statement on pricing is really not complete because it is missing large pieces of the indirect cost and where much of the value comes from.

3. The real issue is risk. For example - I'm going sailing in the Caribbean in about 3 weeks and will be shooting thousands of images. I've been planning this for months. Many of my shots will require a tripod. I'm going to have to carry this gear on aircraft, on boats, it will be near sand, saltwater, etc... Do I want to take something on this expensive trip that might break or has a reliability issue and then be thousands of miles from a replacement (replacement is not possible, actually)? Then it is a question of the incremental cost to me and what that is worth - i.e. risk management. If I have a failure, then I'm in the position of having spent thousands to go down there and back and have nothing to show for it.

I learned this lesson long ago offshore yacht racing. I needed new foul weather gear, was short of money, so bought the cheap stuff. Weeks later, sitting on the rail in a storm getting doused every few seconds with 38F water freezing my butt off, I'd have payed double the cost of what I paid for the good stuff instead of saving a couple of hundred bucks. I nearly did pay double, because I (wisely) went back and bought the good stuff that would have kept me comfortable and dry. In other words, if it matters then it makes sense to not cut corners. Saving the incremental cost is usually not worth the risk.

That means it is a balance. If you don't ever stress your gear, then you don't need good stuff and you will be able to save money. If you do stress your gear, and you don't take that into account, then you are taking on a lot of risk and you will need to decide if it is worth it.

Wow, talk about a topic that has derailed. Everybody agrees that Gitzo makes the very best tripods.

I wasn't suggesting that quality comes without a premium or that you can buy the same quality stuff a K-Mart as at Nordstrom as Thomas suggested. In fact, I don't think I've seen a single carbon fiber tripod at K-Mart, but I'm sure its just a matter of time. And I certainly haven't accused anyone of being foolish for buying a Gitzo nor have I accused Gitzo of price gouging. I don't think any of these are the case. But I also don't believe that Gitzo walks on water or that it is the only company that can build a competent durable tripod.

As John pointed out, pricing is meant to get maximum profit from your product and outside the commodity markets is usually tied to intangible factors some of which may be out of the control of your company and some of which are driven by brand or image. People often have the perception that the expensive product from a prestigious brand will be the better product even if empirical evidence shows that there are problems with the item. Sony is a good example of this brand loyalty trend. Likewise, people place a value on style or fashion or appearance.

In many industries, there are several manufacturers who create equivalent products, even at the highest quality level. John made a point about buying cheap offshore boating clothes. Perhaps in boating there is only one company who makes a decent slicker and everything else is cheap garbage. This isn't the case in many industries.

I don't know boating very well, but I do know mountaineering. In this field, Marmot, North Face, Mountain Hardware, Patagonia and probably a couple others like Lowe fill the very top quality levels in clothing. I own mountaineering clothing from all of these manufacturers, not the cheap stuff. With the years of experience that I have gained climbing and spending time in the outdoors, I can say that they all create equivalent levels of quality and functionality. All of them offer lifetime warranty on the workmanship and against material defects and all of them wear out eventually. Of those four, Patagonia used to charge a premium for an equivalent item. The other three were always pretty evenly priced. I have no idea what the reason was for a higher price on the Patagonia items. Perhaps they do not manufacture their goods in China as Marmot, North Face and Mountain Hardware now do. Patagonia does not have a better Gore-Tex or a better polymer fleece or a better 40d nylon shell material or better stitching. They had a brand with better recognition and prestige.

I am suggesting that the same may be the case with Gitzo versus other established tripod manufacturers. I refuse to put Feisol, Benro/Induro into the class of established tripod manufacturers. I see them as Chinese knockoffs, as do you. But Manfotto certainly has a long heritage of tripods in professional use and Velbon has been making tripods for 40 years and make tripods of their own design in Japan and Taiwan (in full disclosure, they have recently added a Chinese facility).

Also, I had seen your testing John. As I recall, there was no other test sample for comparison and no measurement of movement at the floor or on the tripod. You have confirmed that you can jump around next to your Gitzo on a wood floor and it will not result in perceptible vibration at the film plane. Did you prove that you cannot jump up and down next to a mid-priced or low priced carbon model, or even an aluminum model? Wood is arguably the best tripod material for vibration absorption, but this wasn't tested either (wood tripods are often quite expensive too). Did you measure the vibration at the head with any type of instrument and have a baseline of what would be acceptable and what would not? Unless the company is testing according to ISO or ASTM standards, they are generally "testing" for marketing reasons. We know that there are not standards in the tripod/head industry because we know that all of the manufacturers are using load ratings that do not compare evenly.

John also stated that Gitzo must have thought very carefully about the fiber layup so that the tripod could support the average American male. I have to argue this to the contrary as well. 10 years ago I was riding a Trek carbon fiber road bike. I could easily sit across the top tube of this bike without the tube shattering and it was a fairly early and crude carbon fiber design (the bike was probably 5 years old when I bought it). That bike was significantly lighter than an aluminum equivalent of the time. I am absolutely certain that the Gitzo tubes are far stronger than would be needed to meet the design spec and as I said before, the leg locks have been the weak link.

I didn't buy my Velbon on price alone and I didn't buy it to prove every Gitzo owner wrong. I bought it because it met my needs and because a landscape photographer who I know has been using a Velbon El Carmagne for a decade in conditions similar to what mine will see. Snow, sand, below zero F temps, occasional bashing on rocks in slot canyons, desert heat, submersion in water, rough and dusty rides in the back of a jeep, occasional use as a walking stick, tropical humidity and occasional salt water exposure. These are what his has seen, what my Bogen 3021 has seen and what my Velbon will see. I would say that I put my gear through demanding conditions just as many others here do and I have no doubt that it will survive.

I would say that the opportunity for failure is similar in all three brands and that it is low. In fact I would say that the aluminum Bogen 3021 has the least chance of catastrophic failure because the aluminum tubes can bend, not shatter if something heavy landed on them. From this point of view, I don't see any increased risk in using the mid-priced tripod versus the Gitzo. All of them are designed so that they can be torn down, cleaned and repaired. Considering that parts availability for Bogen/Gitzo is limited (as in almost non-existent) in Denver and completely non-existent in Colorado Springs (a city of 400,000), I would say for any remote travel, if your tripod should break you will be up a creek regardless of the brand. You better have a backup or have spare parts in advance.

Imitation is the sincerest form of flattery, when it stops short of copying and counterfeiting. From what I've seen, the ones that look most alike are Giottos and Induro, not Gitzo - not that they all don't have similar implementations of some features. I think the people that need to stop the rumors aren't Gitzo - they've made their point in several places. I think MAC would be wise to squelch the rumors because they are the ones that need to validate the quality of their product in competition with an established product line.

Actually, I believe Manfrotto and Gitzo are owned by the same company and aimed at different price points in the market.

Also, I had seen your testing John. As I recall, there was no other test sample for comparison and no measurement of movement at the floor or on the tripod.

I actually fiddled with this (qualitatively) with a glass of water on the floor. There was definite - and in the world of photography - gross movement/vibration.

You have confirmed that you can jump around next to your Gitzo on a wood floor and it will not result in perceptible vibration at the film plane. Did you prove that you cannot jump up and down next to a mid-priced or low priced carbon model, or even an aluminum model?

yes. and the results were so bad that I want to reconfirm them first. I used an older Velbon aluminum tripod that would go for about $75-100 today.

Wood is arguably the best tripod material for vibration absorption, but this wasn't tested either (wood tripods are often quite expensive too).

Actually not if you consider weight as a critieria too. They tend to be heavy. Berlebach tripods are some of the best in wood, and they are no tall that expensive either.

Did you measure the vibration at the head with any type of instrument and have a baseline of what would be acceptable and what would not? Unless the company is testing according to ISO or ASTM standards, they are generally "testing" for marketing reasons. We know that there are not standards in the tripod/head industry because we know that all of the manufacturers are using load ratings that do not compare evenly.

Actually, this is funny/ironic. There are not testing standards in tripods - one of the big problems - let along ISO or ASTM level testing. That is the big problem in the whole tripod industry. There is no way to compare short of buying them and testing them yourself.

I didn't measure the amplitude of the vibration because I don't have instrumentation that will let me do that (pretty expensive). I was able to evaluate qualitatively and relatively and you can see what it did to the image quality. There is no doubt which is better and by what factor.

If you read the Markins article, you will see that every 5um of amplitude at the camera translates into (roughly) one pixel of blur. Basically, if you can see the vibration, it is way too much. Also, if you look at the resulting image quality you can get a very good idea what is working and what isn't.



John also stated that Gitzo must have thought very carefully about the fiber layup so that the tripod could support the average American male. I have to argue this to the contrary as well. 10 years ago I was riding a Trek carbon fiber road bike.

I believe you misunderstood me - my point was not that they can but that the load ratings are not the point at which the tripod fails. In Gitzo's case, their spec is where they feel you can no longer reliably take an acceptably sharp picture and that at that point they do not recommend using the tripod.



I would say that the opportunity for failure is similar in all three brands and that it is low. In fact I would say that the aluminum Bogen 3021 has the least chance of catastrophic failure because the aluminum tubes can bend, not shatter if something heavy landed on them.

A leg does not have to break for a tripod to be rendered unusable. There are any number of ways to have a problem and they are easier than you think. Screws can come out, leg locks can strip or break, sand can get in leg sections and lock them up, adhesives can let go, etc... From the tripods I have had (I have had about 10 over the years with 6 of those broken - that says you are wrong on the probability of failure) by far the most reliable have been the Gitzo's. You can always get parts from Gitzo/Bogen directly and there are also often pro photo stores (not pro-sumer) stores in town that have the parts. As well, Gitzo/Bogen has parts for many years not just during the production life of the device - this is also fairly unusual.

Probability of failure is a function of how you use it. There are lots and lots and lots of links about various tripod failures - and usually at inopportune times. If you never stress your gear, odds are you won't have a problem. If you do stress it, then the odds increase dramatically.

Anyhow, we digress.

"The BEST Carbon Fiber Tripod"

Had a thought while making coffee this morning..... "What is the best."

The best, is something everything else is compared to.

The best, what everything else strives to be.

The best, what others can't be but wish they were.

The best has no peers.

The best is what others mime.

The best, is not about price or affordability because being the best is about quality and quality alone.

The best, is the innovator, not the follow on.

The best, is the front runner the rest of the pack is chasing but fails, time and again, to keep up with that everybody recognizes.

The best, is unarguably, the object to behold, not the object you hold in your hand, all the while saying it doesn't matter cause this is what I could afford.

The best makes no excuses.

The best is not marginal.

The best is to hold which nobody can insult by holding up another, of better quality.

The best is honest pride that no one can shake, no matter how hard detractors try.

The best is confidence and security.

The best, when it's in your hand, you know, without equivocation, because it's the best.

The best, when on a table of other samples being given away, you'll choose over all others. Why? Because in your heart of hearts, you know it's the best and you know that it would be foolish not to make "that" choice, cause it was free.

Gitzo, what all the rest of the players in the tripod world wish they could be, but aren't..... The best.

Thank you Thomas for that insightful poetry.

I'm obviously not going to change any beliefs among the Gitzo loyal.

I would encourage those who do not belong to this group to consider that there are other tripod manufacturers who are making high quality carbon fiber tripods of independent design at a competitive price. The world is not made solely of premium brands and cheap Chinese knockoffs. There are a few companies who fit into the space between.

I listened to the flow of this forum and I bought the "Best" for my purposes - a Gitzo GT2530. Maybe someday I'll get another best for me and bigger glass, the GT3530S.


And Beeman458, you missed another definition for Best -

The best, ice-cold _honey_ lagers with friends on a hot Summer's afternoon. ;-)

And way back in this thread I believe the OP said, 'I've gone and bought a Benro."

I never stated that Gitzo wasn't the BEST, except to say that perhaps it wasn't the BEST balance of weight, strength, durability AND cost.

I did say that they have the best advertised strength to weight ratio. I also said that they have a proven track record for parts availability (because I know that tripods will require parts during their service life).

There is no independent empirical evidence to support the theory that Gitzo is the best tripod on the market. There is only their own marketing materials. There are tripods that are taller, stronger, slimmer, even more expensive (although I think the titanium traveler takes the cake in this category), etc... Load ratings are not tested against a standard, so there is no way of comparing the load rating of a tripod from one manufacturer against the tripod from another. Therefore, we cannot say that Gitzo has the BEST strength to weight ratio other than to say they have the best advertised strength to weight ratio.

In school, I was always a big fan of destructive testing and analysis. I'd be happy to have every tripod manufacturer send me a full line of tripods for destructive testing in a hydraulic press so that we can get to the bottom of this once and for all. We can smash each tripod and determine what the point of failure was and at what load the failure occurred. We could even measure deformation prior to failure (so that we can account for leg locks slipping). There's a good 30 undergrad students at the alma mater who would probably love to do this for school credit.
