Canon DLC Publishes Cinema EOS White Papers

The Canon Digital Learning Center published 4 new Cinema EOS white papers. The new papers are:

NEW: Personality of the Canon Cinema EOS Lens: Design Strategies
The newer generation of Cinema EOS lenses came from multiple optical design resources within Canon, such as ourEF Lens and Broadcast Lens designs.

NEW: Personality of the Canon Cinema EOS Lens: Image Sharpness
A design goal with the Cinema zoom lenses was to achieve an overall optical performance that would equate with the best of contemporary prime lenses over their respective focal lengths.

NEW: Personality of the Canon Cinema EOS Lens: Color Reproduction
The new generation of Canon Cinema lenses paid high attention to optimizing color reproduction of the lens-camera system, such as how it reproduces skin tones of various ethnicities.

NEW: Personality of the Canon Cinema EOS Lens: Contrast
Achieving a high contrast ratio is universally sought by cinematographers and is always a central design goal for the optical designers.

Tamron SP 150-600mm F/5-6.3 Di VC USD Review (ephotozine)

 

The eBand coating delivers good results when shooting against the light – 1/320, f/7.1, 500mm, ISO 320

All pics used with permission.

ephotozine reviewed the Tamron SP 150-600mm F/5-6.3 Di VC USD lens, Tamron latest image-stabilized ultra-zoom. Tamron made a lens that sells for $1069 and offers a lot of bang for the money. Good sharpness, a great telephoto range, and accurate and quick auto-focus are among the highlights of the Tamron 150-600mm (Adorama | B&H Photo), a lens that’s getting one positive review after the other. More details and sample pic after the break.
