Originally posted by Adam I doubt the camera battery would last that long. But based on my personal experience, wi-fi drains it in a matter of hours.
The card itself isn't the most stable, but it should theoretically be capable of functioning continuously for a long time.
USB or Wi-fi tethering, such as this, will work for extended periods however:
Introducing Pentax Wi-Fi & USB Tether by PentaxForums.com - PentaxForums.com Thank you Adam. I have 6 batteries just in case and also some months ago purchased the AC adapter, so I'm prepared
BTW, I own a K-3II, so I think I can't use any app using Ricoh's SDK... at least, yet.
It's a pitty that the APS-C flagship camera lacks of tether capabilites. I'm using K-3II professionally and lately I miss this feature, specially when the people of the ad agency want the photos as they are being taken. In this case I shoot a bunch of products and then pass the card to one of the guys.
Thank you again!
