As seems typical nowadays, after a night with the manual, I believe there are confusing details of the features on the GX7 that are not documented to detail in the manual, or may just be buried deep in some unusual place. I thought it'd be helpful to have these stacked in one thread. Feel free to add workarounds. Here's what I've found so far: - Silent mode Deactivates all flash modes (probably because a flash would negate the benefit of a silent mode) - Electronic Shutter set to (ON) limits ISO settings to 2300 maximum. - Electronic Shutter set to (ON) deactivates all flash modes. - Many settings in the Painterly modes are locked out, like ISO (but similar effects can be adjusted into photo presets in the PASM modes, unlocking the ability to to set things like ISO). - Aperature & Speed are adjustable in at least one Painterly mode (Monocrome) via the Top(then)center icon selection on the on-screen pullouts. - Ultra-High speed burst mode seems to only be available in JPG only choices (No RAW - files written are too large). This is documented, but the chart is a bit confusing. - The displayed Quick Menu choice of either 2 or 10 second timer (only one will show in some locations) is determined by your main menu choice for the same. - I believe I am seeing better/ longer battery life performance using Electronic Shutter much of the time. - Reviewing photos immediately after the shot, when using any large RAW mode may display blurry if you zoom to review your focus - the image will visibly sharpen when the file is finished writing to the card. This issue is doubly obvious when shooting in a burst mode. (Don't get caught assuming something is wrong with your camera's focus) - The display choice for the rear screen that shows only the group of settings you've currently chosen, is 90% selectable and makes a great alternative for accessing other settings, when choices thru the Quick Menu or the Main Menu have you confused. (Example - I have not reset any of the custom function buttons, but in some modes the four May rocker will not call up the features noted on them, then I cycle thru the Quick Menu not finding what I need. Often, rather than fuddle thru the entire set of choices on the Main Menu, I chose this settings display, select on a setting, and all the addl choices for that setting are displayed.) - When shooting in a customized mode (C1/C2/C3 etc) any temporary adjustment to your ISO (and possibly other items like image compensation?) will be reset back to the preset custom mode setting if the camera goes into sleep mode. The situation becomes "Why is it resetting back to ISO 200, when I just set it to 1600?" The answer - ISO 200 is the setting you locked in for C1, etc.
