markm Posted June 9, 2012 Author Share Posted June 9, 2012 Shijan It's not 2.5 Whan its in raw I've found out it has to be converted to 1920x 1080 so you gain nothing. Just my guess work here. Super 16mm frame size is 12.52 x 07.41 mm so Super 16mm lenses need to have a larger rear dia than 12.52 at a guess say another 3 to 4mm to give it the headroom on the sides. So with that assumption only super 16mm lenses with 18 to 19mm rear diameter would cover the BMC. I have a set of superspeeds Zeiss 25mm has 20mm Dia Zeiss 16mm has 18mm Dia Zeiss 12mm has 17mm Dia Zeiss 9.5mm has 17mm Dia Zeiss 10-100mm zooms 14mm Dia I doubt the 12mm and 9.5mm will cover without framing to 35.1 then maybe some cropping might be neccesary. However I doubt many super 16mm lenses will cover the BMC as most have rear diameters a lot smaller than the zeiss superspeeds. Quote Link to comment Share on other sites More sharing options...
sicovdplas Posted June 9, 2012 Share Posted June 9, 2012 16mm won't fit, super16 won't either. 2,5K raw is 2,5k raw it does not downsample to 1080, there is a option for 1080p compressed. Quote Link to comment Share on other sites More sharing options...
markm Posted June 10, 2012 Author Share Posted June 10, 2012 2432x1366 gets de-bayered into about 1920x1080. When converted to RGB you'll have close to a 1920x1080 image. My superspeeds at least the 25mm and 16mm will cover the BMC sensor size and I'll likely get away with a 2.35 image with the 9.5 and 12mm Quote Link to comment Share on other sites More sharing options...

nicinc Posted June 13, 2012 Share Posted June 13, 2012 i don't really understand the 2.5k thing - if it is always 1920x1080 why is it called 2.5k? if i shoot to pro res is it going to be 1920? no problem but just wondering? also can someone suggest some decent EF lenses? i will get the tonkina 11-16 wide for starters Quote Link to comment Share on other sites More sharing options...
markm Posted June 13, 2012 Author Share Posted June 13, 2012 The BMC captures a DNG file. a raw digital image may have a wider dynamic range or color gamut than the eventual final image format, and it preserves most of the information of the captured image instead of the camera deciding. Raw image formats save what is captured from the sensor, and the metadata. Quote Link to comment Share on other sites More sharing options...

markm Posted June 14, 2012 Author Share Posted June 14, 2012 It means the camera records a bigger picture in RAW that then has to be converted to 1920 x 1080. Quote Link to comment Share on other sites More sharing options...
