Kulikov S. N., Ivanov S. A. Test inexpensive megapixel lenses». рp. 62–73.
The article discusses the characteristics and test results of new budget megapixel
lenses production of Korean and Chinese firms for use in TV. All tested autp iris
and manual lenses revealed a fairly high resolution (no less than 1500 TVL) in the
center of the image at full aperture. Characteristics of modern megapixel lenses
cost Chinese and Korean firms are close to the parameters of the ideal lens, the
resolution of which is limited by the diffraction limit. Even small iris these lenses
may result in poor resolution. Extended depth of field by stopping in megapixel
lenses accompanied by a significant decrease in resolution. Implementation of the
automatic aperture lenses megapixel effective. Restructuring aperture of F32 to
F1,8 reduces the resolving power of the lens more than 5 times. In megapixel
camera lens iris should be used only in a fully open aperture, or use special lenses
type P-Iris with a small tuning range of the diaphragm. Keywords: TV, camera,
