Rob Wilton Posted July 28, 2007 Share Posted July 28, 2007 Dear all, do the Cooke S4 lenses need a 6x6 inch mattebox, or will they fit with a 4x4 inch mattebox? I'll be using quite wide lenses - 9.5mm and 12mm thanks! Rob Wilton Link to comment Share on other sites More sharing options...
Jon Kukla Posted July 29, 2007 Share Posted July 29, 2007 (edited) The Cooke S4 lenses only go to 12mm. All of them are 110mm diameter except the 12mm, which is 156mm and thus needs the MB14 (6.6x6.6). However, if you're shooting on S16 and can get the SK4 primes, they include 6mm, 9.5mm, and 12mm, and all of them are 110mm diameter, so you'd be fine for an MB16 (4x4) or MB18 (4x5.65). So the question is - are you on 35mm or 16? And...if 16, are you sure that you're using SK4s for the wide end?

Hi Mitch. 6, 9.5 & 12mm is correct. http://www.cookeoptics.com/cooke.nsf/secondary/sk4 Stephen Link to comment Share on other sites More sharing options...

It looks like the MB16 and 18 can't quite make it (8mm and 7mm, respectively). However, the LMB5 can just make 6mm. Oftentimes, though, the superwide lenses come with their own clip-on hoods. Depends on the rental house. Link to comment Share on other sites More sharing options...
Stephen Price Posted August 5, 2007 Share Posted August 5, 2007 When shooting s16mm with SK's, 18mm and under will cut in on a 4" Matte Box, such as the MB16. In this situation you'll need a 6" Matte Box. Either the MB14 or the light weight shade LMB-4. Link to comment Share on other sites More sharing options...
Johnathan Holmes Posted October 19, 2007 Share Posted October 19, 2007 I have had the 9.5mm start to vignette with a 3-stage MB-18 on Super16, but still workable if you move the matte box closer to the lens. I would think a 6mm would definitely vignette on an MB-18, even with only 2 stages. Link to comment Share on other sites More sharing options...
