So, the "sensor" does 5.9k with no thermal problems. It always has from day one, even when saving 4k files, the sensor reads at 5.9k. The file saved is oversampled 4k from a 5.9k readout. The new firmware takes that same 5.9k sensor readout and instead of saving that file to 4k, it will now saves in to a 5.9k file and places a 15 min cap on it. The 5.9k readout, 5.9k image processing and 5.9k raw out to HDMI continues with no time limit or thermal issues after the 5.9k internal file ends. Im 99.99% certain this 15min limit is only a firmware cripple to protect the S1H What's your source on this? I have noticed that, while shooting 51,200 ISO, the LCD will go from being very noisy to relatively clean once I hit record and I can't imagine any other reason than it changing readout modes. 4K also has a slightly different feel to it than 6K to me, but I could be imagining things. It might be the different codec. Still, 4k is noisier and I've seen other tests online that corroborate that. Also the rolling shutter is different (higher) in 5.9k than 4k on the S1H, and the "per pixel" modes on the S1H imply the other modes aren't. Also the S1H body isn't much larger, but it is larger and I think it has a fan inside it that the S1 lacks, not sure about that though. It might be intentionally crippled but I don't think the sensor is doing full read out all the time. In fact I think 5D2 video first started when engineers noticed they could just capture the low res live view readout and record it. The 5D2 definitely was not doing 30fps 5k readout all the time in live view. Quote Link to comment Share on other sites More sharing options...
