Personal Gear Guru – Cesar

This question was sent to me via our free Personal Gear Guru service by Cesar B., asking about rigging a Nikon SB-900 flash using the included plastic stand. 



What size of a hex stud for a stand of a Nikon SB-900 flash, please?


Hey Cesar,
If you are looking to mount your flash to a clamp with a hex receiver such as a Convi Clamp, or Super Viser Clamp, and you are using the small plastic stand that comes with your SB-900 flash,, the stud you’d need would be the Camera Hex Stud 1/4″-20M, that would thread into the bottom of the plastic speedlight stand. 
In addition to the the Hex Stud, a lot of people choose the Tilting Umbrella Adapter with KG000912 & KG001112 studs, This gives you the ability to angle your flash and use an umbrella to get a large soft light source from your speedlight, as well as mount it on a light stand.
If you want something a bit stronger then the plastic base, you could always pick up the hot shoe adapter as well, which is all metal, is much stronger, and locks positively around the shoe, whereas the speedlight stand is plastic, and the flash is only pressure fit. 
I hope I answered your question. If I can help you any further, please let me know!

Personal Gear Guru – Bob M.

This question was sent to me via our free Personal Gear Guru service by Bob M., asking about rigging both a speedlight and a studio strobe to the 40″ Grip Arm of a 40″ Master C-Stand Kit. 


I’m new to this so here is my question:

All I need to make a 40″ master c stand kit work with a speedlight or studio strobe would be a “5” baby pin”?

Any videos/webinars on using c stands and speed lights?



Hey Bob,
For mounting a studio strobe with a standard baby (5/8″) receiver, yes all you would need is a 5″ Baby Grip Pin 
For mounting your off-camera flash to the 5″ Grip Pin, you will need two more adapters.
First you will need a a 5/8″ (16mm) Receiver with 1/4″-20 Thread
The second adapter you’ll need is a Hot Shoe Adapter to mount the speed light to the 5/8″ Receiver with 1/4″-20 Thread
As an alternative to the 5/8″ Receiver with 1/4″-20 Thread, you can use the Tilting Umbrella Adapter with the Hot Shoe Adapter to mount your speed light to the 5″ Grip Pin and this also gives you the ability to mount an umbrella to give you a large soft light source. 
As far as videos/webinars are concerned, we have a couple for you. 
This is the 5″ Grip Pin Video which shows using the combination listed above.

I hope this answered your questions. Please let me know if I can help you any further.

Personal Gear Guru – Mike

This question was sent to me via our free Personal Gear Guru service by Mike, asking about using two Master C-Stand Kits to support a roll of seamless background paper. 


Can two Master 40-in C Stand with Turtle Base Kit be used to support a paper background roll. If they can, what kind of load can they support. In one of your online videos, you use light stands with arms to support a paper background roll.



Hey Mike,
Yes. Two 40″ Master C-Stand with Turtle Base Kits can support any roll up to 44 lb. (20 kg) in weight (each stand has a load capacity of 22 lb. (10 kg). This would include even the 12′ wide seamless from Savage. A couple of things to keep in consideration:
  1. Always place the large leg in line with the roll of seamless (paper background roll).
  2. Use at least one 15 lb. sandbag on each stand to prevent tipping
  3. Remember the “Righty Tighty” Rule. The load must always go to the right side of the grip head when the handle is facing you. This means that on one stand the handle of the grip head will be facing the camera and on the other, the handle of the grip head will be facing behind the background. 
  4. You can always secure the background to the grip arms with a couple of medium, 2″ “A” Clamps. But you will need a ladder to unroll and re-roll the paper. To make your life easier, especially in a studio situation, you may want to consider the Paper Drive Baby Stand Adapters – Sold as a pair (KG084911) and a Background Paper Drive Set (KG084411) that will allow you to raise and lower the paper comfortably from the ground.
  5. Last but not least, if you plan on leaving a large roll of paper suspended, to avoid the core from bending due to gravity, every day the paper should be given half a turn.
I hope this answers your question. Let  me know if I can help you any further. 
Jason – Your Gear Guru

Thanks for the really useful info. One last question, if you use the paper drive set what is actually going thru the paper tube is it an arm or a pole?
One suggestion I have is why not sell a paper support system as a complete kit, then I don’t have figure out all the parts I need to order.
Hey Mike,
The Paper Drive Set expands into the cardboard core of the paper roll. If you are going to use this method, you wouldn’t even need grip arms or grip heads, just the two stands and you would be good to go. 
As far as creating a kit for the Paper Drive System, it’s an excellent idea. There are just so many combinations (using them with Light Stands or Kupoles, using a single roll versus a three rolls on a multi-bracket, etc.) that it’s a challenge to find the most popular kits for everybody’s needs. I’ll be adding new products and updating the catalog and website towards the end of the summer. I’ll definitely take you suggestion in consideration and see if I can create a couple of kits.



Personal Gear Guru – Tom C.

This question was sent to me via our free Personal Gear Guru service by Tom, asking about stand and boom options for his 7′ Profoto Giant Umbrella. 

Q:  TOM C.

I would like to “boom” a 7′ Profoto Umbrella on casters so that the center of the umbrella would be at a height of 8 feet from the floor. The center of the umbrella would need to be about 5 feet out from the stand measured horizontally.

Can you recommend a Kupo product/products for my application?

Thanks in advance.


Hey Tom,
The stand I’d recommend would be the High Roller (KS300112)
It will be plenty strong (88 lb. capacity) to hold the light, modifier and the 7B clamped to the riser section. 
I do have a simple alternative that may work for you. You can use a Junior offset arm which is about 18″ in length. That will be enough to get you enough lateral separation from the stand so you can locate the light directly above your lens for flat lighting such as Butterfly or Clamshell lighting. The male junior pin would go into the junior receiver in the High Roller Stand’s Combo Head and use a Stand Adapter (KG006312) to mount the umbrella clamp. 
The other advantage of this is that you’d need no counter weights to balance your load. 
For a larger Boom, Matthew’s and Avenger make junior booms if you’d prefer to go that route. 
Of course, you could always use multiple stands, rig a crossbar across the two and then mount your Giant in the center. It will be super secure, but equipment intensive and more expensive. If this option interests you, I’d recommend the following gear. 
2 X Junior Roller Stands
2 X Convi Clamp with Adjustable Handle to attach the cross bar. 
1 X Aluminum Core as a crossbar
1 X 4″ Super Viser Clamp to mount the umbrella.
If you have any other questions, just let me know.


You’re the best! That Junior Offset Arm is perfect! I just need to have enough room to shoot directly under the light with the umbrella and this affords me more than enough space.
