Well Fathers Day for me is a couple of days early, when a nice package arrived from the USA. K-3 Grip and Flucard.
I really like the grip, it balances the camera up very nicely, and fits well to hand. Everything operates well. With the Pentax K-3 grip you get front and back scroll wheels, exposure comp. iso, AE-L, AF and green buttons - nice
.
The Flucard also works well, and allows Liveview, remote touch focus and changing of aperture, shutter speed, ISO, exposure comp from the connected device - which can be smart phone, tablet or laptop. I was using my smartphone, and it worked very well. It took a few minutes to set up and then good to go. Images were good, in focus etc. I am planning to make use of it particularly for tripod landscape photos where you have everything set very low to the ground. No more crouching down to check and set everything. Very nice tech, and works well - same thing is available for the 645Z.
