Matt Jason Thompson Posted February 9, 2013 Share Posted February 9, 2013 Just wondering the difference between the kowa 16D and kowa 8Z (16H). Also, what is the min/max focal lengths useable with the kowa 16D (it has a 44mm thread I believe)? Thanks Quote Link to comment Share on other sites More sharing options...
Mark Dunn Posted February 10, 2013 Share Posted February 10, 2013 I've just checked and the 8Z is a 49mm. The vignetting rather depends on the size of the front element of the camera lens and how close the anamorphic can be mounted. 1 Quote Link to comment Share on other sites More sharing options...
Dom Jaeger Posted February 11, 2013 Share Posted February 11, 2013 The 16D is smaller, so it vignettes a little more. I've used the 16H on standard 8 cameras, and can get down to about 10mm for that format using prime lenses. For 16mm format coverage you might get down to about 20mm, but the front element of the taking lens needs to be no larger than the rear element of the anamorphic (about 44mm for the 16H, maybe 36mm for the 16D), and as close as possible, so a long hood for example will set the lens back and introduce vignetting. The anamorphic doubles the horizontal angle of view, so a 20mm ends up with the horizontal view of a 10mm, which is reasonably wide for 16mm format. I don't think a 16D would get below about 30mm (for 16mm format coverage) even if the taking lens was no larger than the 16D rear element. Zooms tend to vignette more, I haven't got below 15mm (or 30mm for 16mm format) with the various compact zooms I've tried with the 16H. A short zoom range works better than a long one. Long focal lengths aren't a problem (unless the front element is too large). See: http://www.oocities....anamorphic.html Quote Link to comment Share on other sites More sharing options...
