jaapv Posted October 3, 2017 Share #21 Posted October 3, 2017 Advertisement (gone after registration) JPG gets corrected for a lot of things, that is the nature of the beast. If you want to see the difference in vignetting between uncorrected DNG and corrected, take two DNGs, one with lens detection enabled and one with lens detection turned off. 2 Quote Link to post Share on other sites More sharing options...

UliWer Posted October 3, 2017 Share #22 Posted October 3, 2017 It mainly depends on the focal length whether - or better: how much correction is done to the DNG. For wide angles there is also correction of colour shift which is not necessary for longer lenses. But even for a 135mm Apo-Telyt I see some very tiny correction of vignetting in the DNG-file if I use the lens with lens detection. 1 Quote Link to post Share on other sites More sharing options...
jdlaing Posted October 3, 2017 Share #23 Posted October 3, 2017 One thing that I do however notice now when shooting JPB+DNG it that the jpg's get corrected for vignetting but the DNG's not. Is it safe for me to conclude that the 6-bit coding does nothing for the DNG's? Yes. It is safe to think that. Quote Link to post Share on other sites More sharing options...
jmahto Posted October 3, 2017 Share #24 Posted October 3, 2017 (edited) Care to explain?I was referring to the lengthy delay in Leica FW update cycle to fix small things. Edited October 3, 2017 by jmahto Quote Link to post Share on other sites More sharing options...
Leicaiste Posted October 3, 2017 Share #25 Posted October 3, 2017 I was referring to the lengthy delay in Leica FW update cycle to fix small things. Coded M lenses were available since the M8 (2006). I hope it is not a problem with every new Leica. [emoji6] Quote Link to post Share on other sites More sharing options...
