David Bradley Posted April 4, 2007 Share Posted April 4, 2007 Anyone know what focal length would create a relatively objective image on a DSR 570 WS 16:9 2/3" CCD camera? Best David Bradley Link to comment Share on other sites More sharing options...
Premium Member Michael Nash Posted April 4, 2007 Premium Member Share Posted April 4, 2007 Seems we just had this thread recently... It depends on both what you consider "normal" and what you want to compare it to. A 23mm lens on a 2/3" 16x9 chip gives you similar angle of view to a 50mm lens on 35mm Academy 1.85:1. This may help: http://www.panavision.co.nz/main/kbase/ref...lenseqvform.asp But in a pinch just remember that 2/3" optics behave rather like 16mm, using focal lengths close to 1/2 that of 35mm. From there you have to adjust your figure up or down a bit depending on what you're comparing (which aperture/format of 35mm, which aperture of 16mm, and which shape 2/3" chip).

David Bradley Posted April 4, 2007 Author Share Posted April 4, 2007 Thanks Micheal. I should have phrased the question better I suppose. Director wanted I POV using a 2/3" CCD 16:9 and I wanted to be sure I could find a relatively objective focal length before photography commences.

Premium Member Michael Nash Posted April 4, 2007 Premium Member Share Posted April 4, 2007 Unless you're renting HD primes, a good SD zoom should give you the focal lengths you need. For your purposes I would pick a wide zoom, like a 5.5 or so. Link to comment Share on other sites More sharing options...
