    • I did pop the battery before the files were tossed. The camera became unresponsive and wouldn’t even power off. Once at 6fps 14 bit af and again 4fps 14 bit af. I haven’t had issues in single shot, so I’m going out on a limb saying it has something to do with AFc. Using a Lexar 128GB 1667x SD V60 XC II 250 MB/s
    • I could not agree more. Let's hope that Leica fixes this before wedding season starts.  It's a scary thing that you can watch you images and confirm that you have captured them but then your 2 hour of photos are just gone. And even if you think using two card helps, you are wrong. I answered yesterday to emails, "hey, I dont see induvidual photos of my son..." Me: "Yes I'm sorry, our camera lost photos..." and feel like a idiot when try to explain something that just should not be possible. Write also to Leica that they get more these.
    • Can you clarify what you mean the same manual exposure? did you take half the exposure time of ISO100 to match the exposure or you match the manual exposure time?  There are 4 major noise before light become raw digital number: photon shot noise, sensor electric thermal noise, Read noise and quantization noise for ADC. in general, you will always want to using base ISO to minimize the noise. High ISO reduce the exposure time for the same exposure at cost of reduce light/signal goes into sensor. Let's using one example to illustrate: Base ISO100, correct exposure, DR = Signal/(shot+themral+read+Quantization) (equation is for illustration only, uncorrelated noise should be RSS) ISO200 DR= 2X(1/2 Signal)/( more shot noise +2X(1/2 Thermal) +read + Quantization + gain noise (very low for modern sensor))=Signal/(more shot noise + thermal + read + Quantization+ gain noise (very low for modern sensor)) so DR degrade.  For Morden sensor, what you could do to achieve same DR: ISO 100 under exposure by 1 stop but do post process in raw converter to boost exposure by 1 stop. This will match ISO 200 correct exposed DR (which will be worse than ISO 100 correct exposed image as illustrate example above) In theory, even this case, you will still prefer using ISO100 under exposure and do post process because even modern analog ISO/gain has low noise, it will still add additional noise to final image. Post Process is pure digital gain, no noise added.  I don't want to further complicate this matter to talk about dual gain case but we should take advantage of dual gain whenever it is possible. to get best DR, you can in theory only use two ISO, base and dual gain ISO and do rest in post.   Anyway, this seems complicated topic, implementation details may vary but first order underneath concepts are all fundamental EE and signal processing concepts.
