01
When a custom gear makes sense
Your lens is not on our list, has an unusual focus ring, or you need a different width or thickness than our standard gear. Then we build the matching gear for you.
02
Why the grub screw
Just 0.1 mm of diameter decides whether a gear fits well. With the grub screw it is guaranteed to sit tight, and the screw hole does not affect focusing. Without it you take the risk: too tight means sanding it down, too wide means some tape.
03

Every gear is produced individually for you. It is produced and shipped within 1 to 7 working days.

How to Reverse Charge
We offer Reverse Charge for our business customers within the EU. This means that businesses within the EU with a valid VAT number can make purchases without paying the German VAT, which is 19%. However, this does not apply to German business customers, as our shop is based in Germany.
Here is a video which explains how to use reverse-charge:
To make a VAT-free purchase, simply add the products to your shopping cart and then go to the cart, not directly to the checkout. In the cart, you will see all prices including VAT. Scroll down until you find the reverse charge form. Here, you need to enter your VAT number, including your country code, and your email address. Once entered, press the checkout button, and your VAT number will be verified.
If your VAT number is valid, you will receive a notification in the checkout indicating that the prices have been adjusted accordingly and the VAT has been removed.
If this process does not work for you, please don't place your order now, as we cannot refund VAT after the purchase. Instead, contact us with your VAT number and the products you want to order. We will create a manual order for you without VAT.

Guide
How to measure your lens and how our grub screw system works
All you need is a measuring tape or a caliper. Or send in your lens or drop it off at our office in Augsburg and we take the measurements for you. The video shows every step and how the grub screw system works.
1
Measure the focus ring
Wrap a flexible measuring tape tightly around the focus ring, exactly where the gear will sit. In the example the outer perimeter is 246 mm. Alternatively measure the outer diameter with a caliper.
In the configurator you choose whether you measured the perimeter or the diameter. We convert it automatically.
We add 0.5 mm for a good fit
2
Choose the width
10 mm is the standard and works with common follow focus systems. Some lenses have a narrower focus ring, so the gear should be slightly narrower than the focus ring.
Min. 6 mm with grub screw · extra above 20 mm
3
Choose the thickness
The thickness is the difference between the inner and outer diameter, so the wall thickness of the gear. We usually make 6 mm, which gives good stiffness.
Standard 6 mm · extra above 10 mm
4
Grub screw for a perfect fit
A difference of just 0.1 mm in diameter decides whether a gear fits well. That is why our custom gears come with 5 grub screws. This way we guarantee a perfect fit, and as the video shows, the holes do not affect focusing.
You can also choose a gear without grub screw at your own risk: if it is too tight you can sand it down, if it is too wide put some tape between gear and lens.

FAQ
Do I have to measure the perimeter or the diameter?
Either works. In the configurator you choose what you measured, and when you switch we convert your value automatically. We recommend the flexible measuring tape (perimeter).
Why do you add 0.5 mm to my measurement?
The gear has to slide over the focus ring and still sit firmly. The 0.5 mm gives it that clearance. The configurator shows you right away which inside diameter your gear will be made with.
Do I need the grub screw?
We recommend it. Just 0.1 mm makes the difference for the fit, and with the 5 grub screws the gear is guaranteed to sit perfectly. For this it must be at least 6 mm wide. Without a grub screw it is at your own risk: if too tight, sand it down, if too wide, some tape helps.
What material is the gear made of and how is it produced?
Our gears are made with a high-quality 3D printing process using PLA. Every gear is printed individually for you and engraved with your lens name.
Can I order several gears for different lenses?
Yes. After adding one you can configure the next gear right away. Each gear appears as its own line in the cart, with its own lens name for the engraving.
What gets engraved?
The lens name you enter in the configurator, for example “Sigma 18-35mm F1.8”. That way you can keep several gears apart.
How long does it take?
Your gear is made individually and produced and shipped within 1 to 7 working days.
How does sending in my lens work?
Choose “Send in my lens” in the configurator. We measure your lens and make the matching gear. This costs €20.00 net per gear, plus €19.99 once per order for the insured return shipment of your lens. Alternatively you can drop it off in person in Augsburg.
What if the gear does not fit?
If we made a mistake, we will of course change the gear free of charge. If the mistake is in the measurements provided, just write to us and we will be happy to help.
Rather not measure yourself?
Send in your lens or drop it off in Augsburg. We measure it and make the matching gear. Send-in: +€20.00 net per gear, plus €19.99 once per order for the insured return shipment.
