Info Settings - Custom Menu D, Display/Sound/PC > Info Settings > options. Choose which information screens are shown when in review mode and Live View. I check all options as it only a quick push of the Info button to move past screen if I don't want to see it. Note: These same options are available for viewing through the EVF.
Sound - Beeps when focus is locked. Custom Menu D, Speak icon. When using a new lens I keep the sound on until I can know when the when the camera has locked focused. Otherwise it is turned.
EV Step - Custom Menu E, Exp/ISO, Ev Step, 1/3. The same for ISO. If working in a studio this changes to match equipment being used.
ISO Step - 1/3 EV to match other EV adjustments. Custom Menu E, ISO Step.
Auto ISO - I don't use Auto ISO. It is a setting I can and do control to minimize exposure changes that I do not want or expect. Just a personal thing. However I do set up the
Flash settings, The speed at which the flash syncs. All available under Custom Menu F
Slow Limit, 30 (I often use Rear curtain sync and may want to use a very slow shutter speed with the flash firing at the end of the exposure)
Keep Warm Color - Custom Menu G, Color/WB, WB Auto Keep Warm Color, set to Off. Personal choice but the images are good without the extra warm balance.
Color Space - Custom Menu G, Color Space, Adobe RGB. The other option is sRGB which I'll use if I have to shoot many photos and need to quickly send them off. Quite a bit of my work is published in CMYK printing processes using color managed work flows and the extra gamut of Adobe RGB provides me the best flexibility in meeting my customers printing, needs which vary from job to job. But when you move into color managed work flows it can get really complicated, and since most viewing and printing of photographs uses sRGB, sRGB is a very valid choice and simplifies any color management work flow you may choose to use, if any at all - especially if you use a wide gamut color monitor.
Camera/Flash Exposure Compensation - The last setting in the Custom Menu F, Off - If set to on the exposure compensation for the camera will be added with the exposure compensation of the flash. When set off I Can control the ambient light recording as well as the flashes output on the subject.
Copyright settings,
Custom Menu H, Record/Erase, Copyright Settings, Copyright Info, On - this adds you name to the EXIF data of the photos.
