Cameras with interchangeable lenses, like SLRs, need a mechanism to secure the lens to the camera body. This connection must be stable, as dropping or misaligning the lens can cause significant damage. Moreover, this interchange should be quick and simple, making it practical for everyday use.

Historically, lenses were always attached to the camera body using a screw thread. The M39 lens thread, often known as the Leica thread, is particularly famous. Nowadays, conventional lens threads like M39, M40, and M42 are less common outside the realm of analog photography. For most purposes, lens threads have been replaced by bajonet connectors, which are known for their ease of use, allowing photographers to change lenses quickly with a single hand motion.

While amateurs might take the tripod thread for granted, professionals place significant emphasis on this component for a couple of reasons. Firstly, a professional setup, including a lens, can easily reach a price range of several thousand euros. Naturally, photographers want assurance that the tripod thread is reliable and won't allow their equipment to fall. Additionally, for long exposure shots, even the slightest movement can ruin a shot. The camera's mirror can cause vibrations when it flips up, which is why a stable tripod thread connection is crucial. As a result, many photographers don't rely solely on the manufacturer-installed components and prefer to craft their tripod threads.

Whether you're a professional photographer wanting a secure connection between your camera and tripod, or a hobbyist interested in vintage film equipment, the first question often is where to find the necessary tools. In the online store of BAER, the tap manufacturer, you'll find threading tools for rare and unique thread standards. Whether it's special threads in photography like tripod or lens threads, BAER has the appropriate screw taps and thread cutting dies for you. Explore our offerings!

A tripod thread has a tough job. If you've ever held a DSLR camera, you're aware of their potential weight. Especially when paired with a large lens, the device can be quite heavy to handle freely. Tripods are used when the camera needs to remain particularly still, e.g., during long exposure shots. The weight rests on a small, inconspicuous screw connection. This thread must be resilient, especially as the center of gravity shifts forward with larger lenses. In fact, very large lenses have their own tripod thread for additional stability.

The next DIY project can come. Leave nothing to chance and don't work with any standard drilling tools. Save yourself the hassle of blunt or burning drill bits. A real professional drill from BAER will last even in extreme situations. Try our power drills or extreme drill bit, to be able to work universally without having to sacrifice top performance. Our range includes twist drill bit, which are designed for special materials. wood drill bits metal drill bits, concrete drill bits, stone drill bits, SDS-Plus drill bits with PGM certification. Whether impact drilling or rotary drilling, whether hand drill or stationary drilling machine - At UNS you will find what you are looking for!

The use of thread inserts creates highly resilient and very wear-resistant threads even in materials with lower strength. They are therefore very popular for strengthening or repairing threaded connections. Of course, with the BAER claim to always offer the highest quality and precision at a fair price. In addition to thread inserts, thread repair sets & assortments, you can choose from BaerCoil screw tap and assembly tools in a very wide range of dimensions.

The world of thread standards is a fascinating balance between standardization and specialization. In most applications, it's convenient to work with the same standards repeatedly, allowing your equipment to serve multiple projects. On the other end of the spectrum are the specialists. Thread standards designed for a very specific use-case and found only in that context.

Let's start with a thread that can be easily overlooked due to its positioning - the tripod thread, located at the base of the camera body. Its role is paramount, as this tiny thread must provide secure support when using a tripod during photography.

M42mount

This slip ring is designed to mount preassembled C-Mount extension tube systems by passing the tube through the mounting ring and securing it with a locking screw. The locking screw is conveniently located along the top surface of the mount for easy access. The slip ring can easily be mounted to any of our Ø1/2" posts via the bottom-located 8-32 (M4) tap. We also offer slip rings for our Ø1/2", Ø2", and Ø3" lens tube systems.

The SM2A21 Mounting Adapter allows SM1 Lens Tubes or C-Mount Extension Tubes to be installed within SM2 Lens Tubes or Ø2" optic mounts. The outer ring surface features external SM2 (2.035"-40) threads that are 0.16" (4.1 mm) long, allowing the adapter to be used with our SM2 Lens Tubes or SM2-threaded mounts, such as the LMR2. The outer surface of the adapter also has a smooth section, measuring 0.31" (7.9 mm) in length, that can be used to secure it in a Ø2" optics mount with a smooth bore such as the KM200. The lens tube is secured using a nylon-tipped 5/64" (2 mm) hex setscrew.

The smaller tripod thread is primarily used in rangefinder cameras, Single Lens Reflex (SLR) cameras, medium format cameras, flash rails, quick-release plates, and tripod heads. In contrast, the larger tripod thread is used in most medium format and nearly all large format cameras, as well as most connections between tripods and tripod heads.

In this blog post, we dive deep into one such highly specialized area: special threads in photography. Professional SLR cameras utilize unique thread types in two significant places. Can you guess where? We're talking about the tripod thread and the lens thread. Although, in the realm of lenses, a newer solution has been gaining traction for years. But, let's start at the beginning.

Nikon Fmount

Please note that this cage plate does not feature a tapped mounting hole, unlike many of our other cage plates. Due to the bore size, there would be interference between the threaded stud on our Ø1/2" posts and the clear aperture of the bore. Therefore, this cage plate cannot be used directly with Ø1/2" Posts, and a cage system utilizing this plate must be supported using a different method. For a post-mountable solution, consider our SM1RC or SM1TC lens tube clamps, but note that these parts are not cage compatible.

These mounts are compatible with our C-Mount extension tubes and allow for integration with our Ø1/2" optical posts, 30 mm cage systems, and Ø2" lens tubes.

The CP36 cage plate is designed to allow our SM1 Lens Tubes or C-Mount Extension Tubes to slide into the cage plate and be locked in position with a nylon-tipped 8-32 setscrew. This is ideal for situations where it is not desirable to thread the lens tube into one of our threaded cage plates. It will also allow our Ø1.2" free-space isolator packages to be integrated into a 30 mm cage system. A double-bore design gives three points of contact for stable and secure mounting. Each cage rod through hole is accompanied by a side-located locking M4 setscrew, which can be secured using a 5/64" (2 mm) hex key or balldriver.

Then, there are the filter threads. Filters are thin glass or plastic plates placed in front of the lens to achieve specific effects, analogous to Instagram filters but in a physical form. Filter threads are quite short, requiring only 1.5 to 2 turns for attachment. Filters should be easily interchangeable and are, by nature, lightweight.

Tripod threads have their own standard, DIN 4503 (Camera and Accessory Tripod Connections). However, their dimensions are so similar to the UNC thread that the two can almost be considered interchangeable.

Lens mount

This lens tube clamp is designed to enable easy installation and removal of C-Mount extension tubes from optical systems. To remove an extension tube, simply unscrew the 3/32" (2.5 mm) hex clamping screw, flip the mount open, and lift the tube straight up and out. This feature is useful for users who, because of tight space constraints, do not have the room to slide the entire extension tube out of a mount. The clamp can easily be mounted to any of our posts using the #8 (M4) counterbore on the bottom of the clamp. We also offer clamps for our Ø1/2", Ø2", and Ø3" lens tube systems.

Though traditional lens threads have largely given way to bajonet connectors, there are areas where screw connections remain preferred. The C-Mount is a standardized lens thread introduced in the 1920s for film technology, and it's still widespread today. The lens thread has an external diameter of 1 inch with a pitch of 1/32 inch. The flange focal distance is 17.526 mm.
