camera lens

The principle of lens coating: By forming thin film layers of different thicknesses on the surface of the lens, the reflection and interference of light between the thin film layers can make the phase of light of a specific wavelength destructively interfere, thereby reducing reflection. This way, the lens can more effectively pass through the light, reduce the loss and scattering of light, and improve the contrast and clarity of the image. Lens coating has the following benefits: 1.Improve light transmittance: Coating can reduce the reflection of the Camera lens surface, improve light transmittance, make the image brighter and clearer, and reduce light loss. 2.Suppressing light scattering: Coating can reduce the scattering phenomenon on the lens surface, avoid light interference inside the lens, and improve the contrast and detail clarity of the image. 3.Anti-scratch and anti-fouling: Coating can increase the hardness and anti-scratch performance of the lens surface, effectively protecting the photographic lens from scratches or contamination, and prolonging the service life. 4.Reduce halos and ghost images: Coating can effectively reduce the generation of halos and ghost images, making the image more realistic in color and clearer in detail. 5.Improve color reproduction performance: Coating can improve the dispersion properties of light, improve the lens's ability to restore color, and make the captured image more vivid and natural.  

Standard Zoom Lens: Standard zoom lenses usually cover a wider focal length range, such as 24-70mm, and are suitable for shooting various scenes such as daily life, travel, and landscapes. Wide-angle Lens: A wide-angle lens has a wider field of view and is suitable for shooting scenes such as landscapes, buildings, and large groups. It can also be used to create special perspective effects. Portrait Lens: Portrait lenses usually have larger apertures and focal lengths, such as 50mm f/1.8 or 85mm f/1.4. These lenses can produce a shallow depth of field effect, making the subject stand out from the background. fixed focus lens: fixed focus lenses have a fixed focal length, such as 35mm, 50mm, or 85mm. They typically have wide apertures and offer excellent image quality and good low-light performance. Telephoto Lens: A telephoto camera lens has a longer focal length, such as 70-200mm or 100-400mm, and is suitable for shooting distant subjects, such as sports events, wildlife, etc. Macro Lens: Macro lens is specially designed for photographing very small subjects, such as insects, flowers, etc. They offer high magnification and excellent detail capture. Fisheye Lens: Fisheye lens has a large viewing angle and can capture panoramic images or produce strong distortion effects. It is often used for creative photography or specific shooting needs.
