2.35:1 Aspect ratio

What is the best method for shooting this ratio? Cropping in camera, cropping in post or the elusive Cannon lens converter I've heard all about but never managed to track down?

Obviously there is a compromise with any method. The first to being a loss in pixels and the third being extra glass to carry around and a loss in optical quality.

Any thoughts?

Hi Paul,

Your best option depends on how you intend to post produce your content. If you have a real powerful post production system, us the Canon product. On the other hand if you have a not to cool system, cropping the 16:9 image to 2.35:1 aspect ratio will probably be the easiest way to work.

The product name for the Canon product is the ACV-235 Anamorphic Converter, has a list price of $29,500 dollars and there is no evidence that its use degrades the image optically in any way. This item is for 2/3 image size format 16:9 HD lenses and cameras and squeezes a 2.35:1 aspect ratio image into a 16:9 aspect ratio image. Similar to the Angenieux converter "CLA 35 HD", it causes the resulting image to be upside down. A powerful postproduction system will be able to unsqueeze the image back to 2.35:1 and turn the image right side up without a problem.

Please be advised that real cinematographic anamorphic images are 2.40:1 aspect ratio (when shot using Panavision Anamorphic lenses.)
