Tripods are used for many applications where you need to support something above the ground. There are some similarities and difference in tripods depending on the application and where in the world they are being used.
Some common applications are for use with: Astronomy, Binoculars, Cameras, GPS receive antennas like for the PLGR or DAGR or Trimble antennas and Surveying instruments.
Weight Carrying Capacity
Most tripods have some design limit on how much weight they can carry. If that weight is exceeded the clamps may not work, allowing the load to move in unexpected ways (and it may allow the load to hit the ground). For example the Slik F740 can not hold the Nikon D300s and a heavy lens without tipping down, but the TiltAll or Arri tripods can hold it.
Spreading of the legs is another problem as weight is added. An outdoor tripod, like the Arri and TiltAll have spikes that can be extended from the feet to dig into the ground which helps the legs from spreading. But when indoors when the spikes are retracted to protect the floor the rubber crutch tip feet may slide on a smooth floor lowering the weight capacity. There's a triangular base that can be used to keep the legs from trying to spread out.
It may be that the weight of the tripod should be about weight of the camera?
The Manfrotto 055 & 410 head weigh 8.5 pounds and rated to carry 11 pounds.
The Slik F740 weighs 3.5 pounds and is rated to carry 3.2 pounds.
Vacuum tubes require a filament power that's greater than or equal to the power consumed by the plate circuit.
An astronomical telescope depends more on the mount than on the optics of the telescope. The major effort goes into the pier and mount.
Maximum and Minimum Height
The most common tripod use is to hold something at standing eye level, like a telescope, camera to surveying transit or theodolite. There are also times when you want to hold a camera close to the ground and at the same time be able to pan, tilt or rotate it and some tripods like the TiltAll allow the central support to be installed from the bottom. Table top photography would appear to be a place for a small tripod but that doesn't work out to be the case, see Center of Mass below. So for that application a clamp with a 1/4 bolt or ball head is the way to go.
Center of Mass
There are a number of "cute" small (under one foot tall) tripods on the market, but if you place a load that has a center of mass that's outside the tips of it's legs the tripod will fall over on it's side. This happens with those small tripods with almost any practical load, even a USB camera will flip it over because of the weight of the cable.
If the tripod is going to be used for movie or video where the head will be panned left or right then there are new things to consider.
There needs to be a way to plumb the rotation axis (or level the head) so that when you pan the camera keeps pointing at the horizon instead of pointing into the ground or the sky.
Also the panning motion needs to be smooth. The Arri tripod has a "Ball Head" that's a hemispherical surface and the moving parts have good lubrication so it pans very smoothly.
An even better head is the "Fluid Pan" head that pans smoothly with heavy loads.
Most surveying tripods have spike points at the tip of each leg and a small shelf that you can stand on to force the tip into dirt. These legs do not work on smooth surfaces where they might allow the legs to open.
The TiltAll camera tripod has rubber hemispherical tips that work well on smooth indoor surfaces and also have points that can be screwed out when you need more traction in dirt.
See my Telescope Mounts web page.
Equatorial (Polar) (Wiki) where there's a plate that can be adjusted so it's plane includes the North Celestial Pole (Wiki). This type of mount allows one motor to de-spin the Earth's rotation and set the hour angle (Wiki) and at right angles to that axis an adjustment for declination (Wiki).
Example: Celestron C8 (Wiki)
Azimuth-Elevation (Wiki) used on lower cost telescopes. Will work with GoTo telescopes (Wiki).
Example: The Celestron NextStar 60
Dobsonian (Wiki) is a head type where the astronomer moves the telescope by pushing on it. This requires both a balance about the horizontal and vertical axis of rotation and in addition some friction on each axis so the scope will stay when the pushing stops.
Many tripods are custom made for a specific application. Usually there's a good reason like to minimize weight or size. In early times standards had not yet developed so each company did their own thing. In the case of a military product making instead of using a standard tripod increased the company profits.
How the head can be moved (or not) and how it attached to the item to be supported can vary a lot. In addition there are adapters to allow one tripod to be used for an additional purpose besides the one it was designed to do. The attachment method needs to match whatever you want to support.
1/4"x20 Male US Camera Thread
This is probably the most common attachment for tripods and is intended to hold a camera as used in the U.S. and many other countries.
Examples are: TiltAll camera tripod, Binoculars (see holding)
3/8"x16 Male EU Camera Thread
You would expect the European camera thread to be some metric size, but it's really a U.S. 3/8"x16.
Example: the Arri Movie Camera tripod.
This is a larger thread than the US 1/4" so would be better for heavier cameras.
Quick Release (proprietary)
Instead of turning a screw or the device you are attaching a proprietary plate is attached to the device and then it can be quickly installed or removed from the tripod by the operation of a lever. The problem with these is that they are all different but you can get more top plates of the same kind.
Example: Slik F740 camera tripod, Veibon QRA-635L Quick Release Adapter used on the Arri tripod to hold the Nikon 300mm telephoto lens.
3-1/2"x8 Male Surveying Thread
This is an older surveying tripod thread.
Example: Leitz 115A Transit
5/8"x11 Male Surveying Thread (Solid)
I got an adapter from 3-1/2"x8 to 5/8x11 so that I could mount GPS antennas on a 3-1/2"x8 surveying tripod.
Example: DAGR GPS receiver with external antennas (scroll down for many examples), GPS antenna on range pole, Trimble Military GPS Antenna 17572-00, Trimble 4000ST/SST Antenna, Trimble GeoExplorer II GPS receiver, Trimble 25785-00 ProBeacon Differential GPS receiver antenna,
5/8"x11 Male Surveying Thread (Hollow)Modern surveying instruments that make use of a Tribrach (Wiki) typically includes an optical plummet instead of or in addition to a hook for a plumb bob (Wiki) require a hollow 5/8x11 male thread on the tripod.
Note: A Tribrach is only needed if the surveying instrument does not already have an optical plummet built in and you don't want to use a plumb bob (Wiki).
The problem with plum bobs is that wind moves them and the price goes up with the weight.
Examples: Sokkisha/Sokkia/Leitz N010C Theodolite (aka: 10C Transit), Nikon NT-2S theodolite,
This tripod from eBay seller fltgeosystems was titled:
"Aluminum Survey Contractor Tripod for Transit Laser"
and in the description they called it:
"Northwest NAT83 Survey Aluminum Tripod"
Bottom of head
The lateral position of the 5/8" bolt can be moved over
a considerable range (over 2") so that the center of
instrument rotation can be placed exactly over a point
on the ground. Note at the bottom of the handle there's
a "V" shaped wire for hanging a plumb bob.

T. F. Randolph LevelThis tripod can only be used with it's associated level. The tripod has the mechanism to plumb the horizontal axis of the level, unlike modern transits and theodolites where that function is part of the instrument. All modern tripods do not have a leveling mechanism although some do have a bubble level on the head that's used to adjust the leg length to rough level the head.
I had a couple of these, one modified for a view camera and used the other one for a Nikon or Hasselblad camera. Very robust and reliable. All metal construction. But heavier and larger to carry then the modern plastic tripods.
Ultra Compact Light StandThis is a stand for holding photo studio lights. This one can be made very small which makes it handy to take on a location shoot.
Shown with the legs down, but they can be folded up parallel to the center making it very compact when fully folded.

Manfrotto MT055XPRO3 Aluminum Tripod & 410 Jr. Geared HeadThe Nikon D800E weighs 2# and the 300mm f/2.8 ED-IF AI-S lens weighs 5# for a total of 7#. Much too much for the Slik F740 tripod which is rated to carry 3.2#. The small amount of Manfrotto equipment I do have is all made with excellent build quality. This combination of tripod and head is rated for 11# so has some headroom. Note the 055 tripod & 410 head weigh 8.5 pounds. So maybe a rule of thumb is that the tripod weighs about the same as the weight it's going to carry?
The patents make clear this is a tripod specifically designed for Macro Photography. While the Tilt-All tripod is not mentioned by name the idea of inverting the central column is mentioned. But the new tripod design offers more camera freedom for macro photography.
Another advantage of the 055 compared to the TiltAll is that the 055 does not have a cylindrical column. The TiltAll cylindrical column is handy in that it allows turning the camera, but with a heavy camera it will turn all by itself, not a good thing. This may also mean the macro configurations of the 055 may depend on which legs are at different angles. TBD.

410 Jr Head
The TiltAll tripod and the Slik F740 are fiction clamping heads with levers to position camera. This is a "geared" head meaning that to move the camera you turn a knob which turns a gear train. This is good for heavy equipment since a friction clamp will allow the camera to fall if it comes loose or if you are not paying attention. With a geared head there will be no sudden camera movements. There is a spring loaded sleeve that will disengage the gears to allow large movements.
This is a head for a still camera or a movie camera that's "locked down" and will not be moved during a take.
2022 April 30 - While the 055 tripod and 410 head were only a few days from opening the box the plate was loose and the camera wobbling. This is because the factory/dealer failed to use thread locker. When I tried to assemble the parts the spring that holds the silver release button ran away. I replaced it with the spring from a ball point pen that I cut shorter (cut off about 1/4"). Note the tension on the pivot can be adjusted using the brass nut if the screw is snug but not tight. The brass nut does not move with the lever. The brass nut should be turned Clockwise to tension the pivot spring. Once the assembly is all connected you can adjust the spring using both a 3mm hex wrench and a 14mm box wrench (or adjustable wrench). The tension can be read by the angle between the tip of the spring in the hole in the brass nut and the slot in the lever arm.

Fig 1 Comes with a small carry bag.
Fig 2 Range pole (in 5 sections that screw together with 5/8-11 threads) friction clamp laser shelf (5/8-11) and large foot with male 5/8-11 plus small tripod.
The Telescoping rod with the spring plunger and clamp that would be placed at the bottom,
requires that the rest of the rods be installed with the male threads pointing down. Maybe this is common for laser levels?
I have just not installed that part and instead used the rubber pad foot at the bottom and installed the remaining rods with the 5/8-11 male threads pointing up, as is common for surveying.
Also not installed is the friction clamp shelf. While the shelf is shipped with a 5/8-11 male - 1/4-20 female adapter installed, that adapter can be removed so you end up with a standard tripod 14-20 male pointing up. Which would be great if the RA-1 antenna had a 1/4-20 socket, but the large threaded hole on the bottom of the RA-1 is a 10-32 thread NOT at 1/4-20 standard tripod thread!
Now need to figure out how to mount the RA-1.

This is typically used for Studio Lighting, but is also useful for things like mounting a GoPro camera.
I have added a hot shoe clamp (not part of the factory 035).
Max Load = 15 kg (33 pounds) but it feels much stronger.
The wedge can be accessed by removing the Small black knob. It can then be plugged into the "V" to give a flat parallel face instead of the "V", like for clamping to a shelf or table top.
