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

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.
