One of the things you can do is to get a viewfinder such as
Yashica Tele-Wide Finder
They are available used on eBay.
This will allow you to turn off the rear LCD display for framing, and may be useful if you dont need it to be exact edge to edge coverage as it mainly works with the 01 and long end of 02 lenses.
I took my Q7 on vacation last week and was able to go through three batteries in a day as I did not turn off the rear lcd and did also take some videos.
I could charge each night at the hotel so it was not a problem for me. Otherwise I would have used my telewide.
If you think it will work for you and you can't find one let me know if you need to borrow mine.
