Hi, all! 

Has as anyone found any good wide angle adapters for Kowa 16-H/8Z? It's one of the wider projection lenses (50mm ff taking lens if cropped to 2.40:1), but it doesn't quite get that Hollywood wide anamorphic look. I've been looking at the Dog Shidt Optics FF38, but I'm not sure if it would work to put the projection lens between the ff58 and the ff38 wide angle adapter front end.

Hi, all! 

Has as anyone found any good wide angle adapters for Kowa 16-H/8Z? It's one of the wider projection lenses (50mm ff taking lens if cropped to 2.40:1), but it doesn't quite get that Hollywood wide anamorphic look. I've been looking at the Dog Shidt Optics FF38, but I'm not sure if it would work to put the projection lens between the ff58 and the ff38 wide angle adapter front end.

unfortunately the ff38 has a rear element clear aperture of 36mm, So puts some limitation on its use with anamorphic lenses.

 

the ff38 has been designed to fulfil near transparent afocal optical performance when used on a 36mmx24mm sensor area on a 58mm/f2 aperture. Being over engineered it does infact cope with as wide as 50mm,f1.4 apertures without significant light transmission loss or vignette on 36x24mm sensors.

 

50mm taking lens plus a 2x ana on 36mm sensor width cropped tp 2.4/1 is approximately similar to a 35mm spherical taking lens on a 36mm wide sensor area cropped to 2.4/1, so using a ff38 on the front will likely produce vingette too harsh to make the expense and extra weight/length worthwhile.  I'd played around with making scaled up ff38's with 50mm rear elements but 95% of users don't realised or value how hard it is to manufacture a wa attachmant that does what the ff38 does, and as such a £500-600 price point aint viable
