Modern lens design requires the ability to adapt to a variety of shooting conditions, especially in backlit conditions in the field of photography, the camera's ability resilience very high light requirements.Usually in backlit conditions in the photo shoot to often find unexpected formation of the spot or ghost, especially when viewing the sun appears on the screen in or screen around, spot production has been plagued us, they come as the main causes lens within the lens surface reflection and the reflection wall. Currently, in order to eliminate such unwanted reflections, commonly used approach is the multi-layer lens coating and the inner wall of the extinction of the process.Coating can increase the light amount of light through the lens to reduce reflection, and ultimately reduce the number repeated in the lens between the light and reduce the occurrence of the spot under the backlight. When we look at the lens surface, the color is to be able to see the reflected light actions, in general, so the darker, darker sense of the eye, indicating the less reflection, the more effective this type of coating. Although nowadays widely used multi-layer coating process, zinc oxide but due to the number of zoom lenses a lot, for the anti-spot capacity is very bad, and all lenses are used for coating process takes a very high cost. Therefore, it can be said that the more expensive zoom lens, the main part of the cost is reflected in the handling of the lens, the lens of its implementation of the coating process the more the better lens overall coating.On the other hand, Magnesia as compared to fixed-focus lens zoom lens moving quantity, travel is also large, this part of the tube wall corresponding to the extinction process is also more difficult. As long as we will fully open aperture zoom lens in the light can be clearly observed in the handling of the lens effect of the wall. Typically, manufacturers of extinction due to the different treatment processes are very different.Most digital cameras can not install the home protection filter, or installation is very inconvenient. Usually bare, Titanium dioxide exposed in the camera when shooting very easy to accidentally get on the point of dust, fingerprints or by leaving a point on the spit or something. Although the lens surface of the fingerprints, dust, water stains have little bearing for imaging. If there was no strong direct sunlight and glare on the lens can cause fog. But you love the camera, how can we tolerate the beloved's camera lens into a large painted face? Not clean, how to do? Rub!Are generally multi-coated lens, believe it will scratch the coating, scratch the lens. Irreparable damage to the lens. We are in the end is clean or not clean it? My experience is that the lens is always more friction worse, rather than the more friction the better, do not expect you can just put the lens back to the new look from factory. Therefore, we suggest do not wipe the lens untill it's the last resort! Article Tags: Lens Coating, Lens Surface, Coating Process, Zoom Lens
