Ce que le fil a révélé

• Les lentilles anamorphes Primo sont plus lourdes et plus grandes que les anciennes lentilles anamorphes de la série C, mais sont considérées comme utilisables pour une utilisation de Steadicam.
• Les verres anamorphes Primo 35mm et 40mm pèsent entre 14,8 et 15 livres et ont une distance de mise au point minimale de 3 pieds 6 pouces.
• Les lentilles anamorphes de la série C sont sensiblement plus légères, avec des longueurs focales allant de 20 mm à 180 mm et pesant entre 3,5 et 7,7 livres selon la lentille.
• Anamorphic lenses require compromises in composition and shooting aperture due to their characteristic depth of field behavior differing from spherical lenses.
• Wide anamorphic lenses such as 35mm or 40mm are traditionally used for wide shots rather than close-focus work, and diopters are not practical for moving camera work.
• Anamorphic lens setups mounted on moving camera rigs, particularly in low mode, may develop vibration issues that could be mistaken for camera movement.
• Stiffening the rig with carbon fiber rods and lightweight bridge plates can help reduce vibration problems with heavier anamorphic lens packages.
• Anamorphic projects require extended prep time and cannot be assembled quickly like standard sphericam packages.
• An experienced focus puller with specialized knowledge of anamorphic lens behavior is valuable for successful anamorphic shoots.

Dépend de

• Weight specifications provided are primarily for Primo Mark I lenses; Mark II close-focus versions should be similar but exact weights were not available at time of discussion.
• The discussion focuses on Panavision anamorphic lenses; information may not apply to other manufacturers.
• Vibration concerns were reported for specific Steadicam work but the extent of this issue across all anamorphic applications is unclear.
• Experience level varies among contributors; some had direct operator experience while others contributed as assistants or through secondary research.
• The discussion occurred in 2009 and may not reflect current equipment capabilities or alternatives.
