Finally bit on the Pentax Flucard, managed to buy a "gently" used one for less than half the new. For those not familiar with this basically it gives limited wireless tethering to the Pentax K3II as well as other Pentax models. Product page of Flucard For Pentax 16GB O-FC1 - RICOH IMAGING EUROPE S.A.S Just got the card in and installed so still learning but here's what I've found so far: Setup went quickly and easily in camera. Put the card in the Number 2 slot, go to the menu and turn it on, and wait a few seconds for it to boot up. Connection by my tablet to the card via wireless was quick and easy. Search wireless connections, find the Pentax card, and connect. Bringing up the browser window hit a snag. Typical Pentax instructions - "once connected to card open browser window and go to menu screen"??????????? WTH???? Scratched my head on that one as my open browser window waited patiently for an address (something they failed to mention in the instructions). Few mins on google found the address was the IP address of the card. Slap head move on. Menu screen is fairly straightforward, and operation was simple. You can change the shutter, aperture, and ISO from the tablet - nice. You can magnify the live view from the camera up to 10x - nice. You touch the screen at the point you want the AF to focus on and snap the shutter - also nice. I've got to admit it's cool to be standing away from the camera touch the screen and hear it focus and snap the shutter. Change your settings, and do it again, all without touching the camera. It can also connect multiple devices "at the same time", so one can operate the camera and another can be transfering images. So far I'd be pushing it toward miracle (since only K1 and 645 support tethering), except for one little annoyance. You can only view or transfer remotely JPEG files, no support for Raw. You can save a raw file to card, but you have to transfer the files via wired connection or pull the card. The Pentax workaround is save as a Raw+ (two files, one Raw one JPEG). So the jury is still out on if is worth it, or I got conned into buying the snake oil.
