Why have bluetooth or WIFI on when not using them., and so on there are lots of way to move away from default power consumption usage. If a device is plugged into the HDMI port and/or a Microphone plugged into the Audio In (with Power out enabled) power is used AND also presumably if a device is plugged into the USB-C which does not deliver power then the same is true. Yes each time the camera auto focuses, sensor is used, the Expeed 7 chip processes the result and data is written to one or more cards some power is used. ![]() Shooting RAW images and vigh data video codec/formats (like 8.3k 60p HQ N-RAW N-log) will consume battery life faster than "just" taking smaller images - the act of moving electrons generates heat and this consumes power - cards get hotter with usde and so does the camera. How one chooses to use a camera - take one image every 30 seconds and cycle its power off and back on again after every 10 shots (the CIPA test script) will provide one number or shoot almost continuously at 120 fps a vastly different number and fill rooms with data. That is ON and active not just sitting in ones hands. 250 shots = 250/2 = 125 minutes of continuous use +/- depending on use. When applied to a mirrorless body the CIPA test result is much more of an indication of how long one can have the camera turned on and active. The CIPA results are a very good thing - but one may wish to understand how they are conducted and you can go to the CIPA site and find out - but the testing standard for "VR and Image Stabilisation" is 55 pages long so one has to be committed (or should perhaps be committed to go look) - I know I did. BUT the 250 and other numbers are not real world numbers.Īs those of us who have sailed around this buoy many times over the decades know the results of the standardised CIPA battery tests are just a way to require CIPA members to all describe their products using the same terms, definitions and tests. This is NOT unusual at all - data flows and power is used. ![]() If the Z7 is the same it helps explain why I sometimes have challenges getting 250 shots from a single charge using the Z7. ![]() The battery endurance specification mentions shooting NEF (RAW) can reduce battery performance The Online version of the Z8 reference guide is available to peruse online HERE- it is not available to download yet though.
