Overview of the C Mount Standard and Flange Focal DistanceC Mount lenses are defined by the C Mount standard, which specifies a lens mount thread size of 1 inch (25.4 mm) with 32 threads per inch. This standardized thread size allows for easy interchangeability and compatibility between C Mount lenses and cameras. Additionally, the C Mount standard includes a flange focal distance of 17.526 mm, which refers to the distance between the lens mount and the sensor or film plane. This distance ensures that C Mount lenses achieve proper focus and image quality on cameras designed for C Mount lenses.

Moreover, the ability to use C Mount lenses on various camera systems through the use of adapters further enhances their versatility. Photographers and filmmakers can experiment with different lens combinations, creating unique looks and visual styles that set their work apart from others. This adaptability makes C Mount lenses a valuable addition to any creative toolkit.

1. Advantages in Terms of Versatility and InterchangeabilityOne of the most significant advantages of C Mount lenses is their versatility and interchangeability. With their standardized thread size and flange focal distance, these lenses can be seamlessly swapped between compatible cameras, allowing photographers and filmmakers to adapt quickly to different shooting scenarios. This convenience is especially valuable for professionals who need to work efficiently and adapt to changing environments.

Diffractivelens

C Mount lenses share the same thread size with CS Mount lenses, but they differ in their flange focal distance. C Mount lenses have a longer flange focal distance of 17.526 mm, whereas CS Mount lenses have a shorter flange focal distance of 12.5 mm. As a result, C Mount lenses are not compatible with CS Mount cameras, but adapters can be used to mount C Mount lenses on CS Mount cameras and vice versa.

When using C Mount lenses on cameras with larger sensor sizes, such as full-frame or APS-C, photographers and filmmakers should consider the potential crop factor. C Mount lenses were originally designed for smaller formats, such as 16mm film, and may not fully cover the larger sensor. This can result in a cropped field of view, affecting the effective focal length and angle of view. However, the crop factor can also be advantageous for achieving a tighter composition or extending the reach of telephoto lenses.

While C Mount lenses offer numerous advantages, they do have some limitations that users should be aware of. The original design of C Mount lenses for smaller formats, such as 16mm film, may lead to vignetting or a cropped field of view when used on cameras with larger sensors. This can affect the effective focal length and angle of view, requiring users to adjust their compositions accordingly.

As the world continues to evolve, C Mount lenses will remain relevant and influential. Their adaptability, compatibility, and creative possibilities will inspire generations of visual storytellers to capture and share their unique perspectives with the world. Whether you are a seasoned professional or an aspiring enthusiast, embrace the capabilities of C Mount lenses and let your creativity soar to new horizons. With C Mount lenses by your side, your artistic journey will be enriched, and your storytelling abilities will flourish. So, grab your camera, mount a C Mount lens, and immerse yourself in the world of boundless creativity and visual expression. The possibilities are endless, and the world is waiting to witness the magic you create with C Mount lenses.

C Mount lenses are available in a wide range of sizes and focal lengths, catering to various imaging needs. From ultra-wide-angle lenses for capturing expansive landscapes to telephoto lenses for bringing distant subjects closer, C Mount lenses offer a plethora of creative options for photographers and filmmakers.

DiffractiveIOL

Multifocal intraocular lenses (MFIOL) enable good near and far vision after cataract surgery. Excellent results with cataract patients encouraged ophthalmologists to implant MFIOL after clear lens extraction (CLE). There are two types of MFIOL: diffractive and refractive. In our prospective study we compared clinical outcomes after CLE and bilateral implantation of diffractive (Tecnis Multifocal), (N=100 eyes, 50 patients) and refractive (ReZoom), (N=100 eyes, 50 patients) MFIOL to patients with presbyopia and hyperopia. Near and distant uncorrected visual acuity (UCVA), spectacle dependency, subjective satisfaction and visual disturbances were measured and compared between two groups. Patients achieved good near and distant UCVA in both groups. "Tecnis" group had better near UCVA (statistically not significant) and less night time visual disturbances. "ReZoom" group reported less problems with intermediate vision. Diffractive and refractive MFIOL enable high rate of spectacle independency to presbyopic hyperopic patients with low rate of side-effects. Refractive MFIOL provide better intermediate vision and diffractive slightly better near vision and less haloes and glare.
