GH3 Tips&Tricks
Random Notes
The Electronic (rolling) shutter is limited to maximum ISO1600 and the maximum 1 second shutter speed.
Quick Menu can be customized separately for each mode. C1 to C5 can have individual settings for either still-imaging or video recording.
How to adjust the build-in flash output relative to the metered amount. If you have “Auto Exposure Comp” set to ON in the flash menu, when you have the flash open and are in “A”,”S” or “P” mode (does not work in “M” mode), press the exposure compensation ”+-”-button on top and use the top (index finger) scroll wheel to adjust the power of the flash from -3 to +3 in 1/3 steps. In manual mode, however, the top scroll wheel doesn't change the flash output in any way, and you really do have to delve into a sub-sub-menu.
AFS is single auto focus. Therefore, it does not have to refocus between each burst picture. The burst speed will be fastest in AFS and Manual focus modes. AFF is continuous auto focus but it does not predict motion. AFC is also continuous auto focus but it predicts the motion. Therefore, AFC could be slightly slower than AFF for burst shooting. However, AFC is the better choice for fast motion in a continuous line(i.e: Sports, etc).
A lot of people like 1080p24 with the GH3 IPB mode, which uses 50Mbps. This mode, as some believes, could provide the best looking quantization. However if you'd like things specially for online distribution, 30p and 60p are better options since 60Hz is a most common frame-rate of modern computer monitors. High frame-rate is generally better if the camera is going to be moving as it reduces judder and strobing. Faster is also better if you plan on converting to slow motion in post-processing. Note also that the ALL-I is Intra coded frame where each frame is individually compressed, may provide better options for post-processing than the IPB Bi-directional compression, which basically records the difference between frames.
