This is a hassle-free guide to TOWIN lens, compiling a variety of useful and highly reliable lenses for you. Perhaps you’re a photography enthusiast needing a practical lens to capture stunning images; or perhaps you’re a drone enthusiast looking for the perfect lens to showcase the grandeur of mountains and the beauty of rivers. Whatever your preference, you’ll find the lens that suits your needs here.

Not every lens can satisfy you; the perfect fit might just be found at TOWIN.

When it comes to TOWIN lenses, I was really confused when I first started out. The main categories include M12 Lenses, C-Mount Lenses, CS-Mount Lenses, etc., while the subcategories are further divided into Low Distortion Lenses, Automotive Lenses, CCTV Lenses, and many more. The sheer variety is overwhelming. The model names, like encrypted codes, correspond to different lenses, and not only do the names and prices vary, but their uses and applications are also incredibly diverse. More importantly, the terminology used in different recommendation articles can be inconsistent, easily leading to confusion. It wasn’t until after careful classification and research that I gradually understood: the quality of a TOWIN lens isn’t determined by its specifications or price, but by how and where it will be used.

This “TOWIN Lens Lazy Person’s Guide” helps you organize and analyze the parameters, uses, and applications of various commonly used lenses, allowing you to clearly distinguish which lens meets your needs.

TOWIN Lens Naming Conventions: What are S-mount, C-mount, and CS-mount? Key Abbreviations You Need to Understand

If you see S-mount, C-mount, and CS-mount lenses when buying TOWIN lenses but don’t know their differences, you’re not alone. I used to think that as long as it matched my focal length and aperture, it was fine, until I bought the wrong mount and couldn’t focus. That’s when I realized that understanding the model specifications is much more important than I thought.

S-Mount Lenses：

The S-Mount Lens has a standard mount with a M12X0.5 thread, usually is called “M12 lens”. Because it could be threaded directly into the M12 mount of the PCB (Printed Circuit Board)camera, we also call it “board lens”. It is also called “miniature lens”, as the tiny lens size.

C-Mount Lenses：

The C-Mount Lens with a flange focal distance of 17.526 mm, 5mm more than CS-mount, is mounted to a C-mount camera. It is typically used in Machine Vision camera, USB, GigE and 3D cameras for industrial application then often called “MV lens” , ”FA lens” and “industrial lens”. Now many C-mount lenses are using in traffic monitoring cameras for Intelligent Traffic Systems then called “ITS lens” and “traffic lens”.

CS-Mount Lenses：

The CS-Mount Lens with a flange focal distance of 12.526 mm is designed to attach CS mount CCD/CMOS camera. Our high resolution megapixel CS-mount lenses have Fixed Focal and Vari-Focal length with Manual Iris, DC Auto Iris, P-Iris types, which are widely used in CCTV camera,Network camera, IP camera for video surveillance applications. Using Muti-Coating technology, the lens with IR corrected is perfect for Day/Night security camera.

The TOWIN lens series introduction allows you to understand the naming mechanism beforehand, so you can know which lens best suits your needs and requirements. Buying the wrong lens wastes not only money, but also trust and time.
