4k LENS
|
High-end professional lenses can anticipate a long working life – of the order of a decade or more. This puts a unique context on expectations for contemporary 4K lenses. Such a lens must anticipate a wide range of productions – including theatrical motion pictures, major television dramas and episodics, commercials, and a diverse range of non-entertainment origination.

Macro Lens With macro lenses, depth-of-field is relatively shallow, so extra carefull focus and the use of a tripod or a ring light is recommended. Many professionals typically shot most of their close-up images at small apertures such as f/16 or f/22, for the greatest sharpness from in fromt of the subject to behind it.

CINEMA EOS LENSES

Studying how each of these lenses convoluted with the Canon CMOS image sensor and allied Canon CFA helped establish overall color reproduction benchmarks that guided the subsequent exploration of the new Canon cinema lens spectral response. Video processing – in the form of the digital linear matricing system – was also optimized. The judgment of color balance was made by Canon color scientists in concert with invited directors of photography studying the simulated imagery.

The curves shown in Figures 4 and 5 are the final computer simulated results prior to the lenses actually being built. Canon does not publish actual MTF curves for its high-end professional lenses (a universal practice among all major optical manufacturers). However, it can be said that the actual results achieved in both the CN-E14.5–60mm and the CN-E30–300mm slightly exceed the computer predictions.
