Those of you who regularly follow up on our lab tests are well aware that we found a bug in the first production firmware of the new LUMIX S1II when using 5.8K ProRes RAW with DR Boost “ON”. The merging of the two ISO values into one image was not properly implemented. Now, Panasonic has released new firmware that mainly addresses this bug. Curious to see the results? Then read on for our 2nd part of the Panasonic LUMIX S1II Lab Test… In our first lab test of the new LUMIX S1II (head over here), we could already see the potential of the new implementation of Dynamic Range Boost mode with the internal compressed codecs and ProRes RAW in APS-C mode. Now, the time has come to evaluate the full-frame 5.8K ProRes RAW DR Boost mode. The LUMIX S1II in our CineD Studio. Image credit: CineD The rolling shutter values have not changed with the new firmware implementation; hence, we have to mention the biggest downside of the full-frame DR Boost “ON” implementation: because two different ISO values are joined into one image, read-out times are more than 2x slower than when turning DR Boost “OFF”. We are talking about a rolling shutter value of 27.5ms, which is rather poor, to be honest. However, it is a common theme with dual-gain output sensors, as we have seen similar behavior with the Canon C70, as well, for example (lab test here). Before we begin, a big “thank you” to my colleague...
