Ishpuini, you are correct. The red dot finder is used to point the Q. When you have a 200mm (eq. 1000mm) or 300mm (eq. 1650mm) fov it is difficult and slow to get the subject in the picture. The red dot finder helps so much I doubt anyone would give it up. I wouldn't.
If you have a DSLR you can also use it with a long lens on AF. Look thru red dot to track bif ( bird in flight) and hit shutter button. You are relying in AF to focus bird
. This doesn't always happen. Red dot shows wider field than your viewfinder/lens combo so you see the subject entering/exiting the frame.
I hope the Pentax lens adapter comes out soon. A little worried because my source hasn't heard a thing about it's arrival time. Likely means it is still months away.
You might want to get a cheap adapter and fix it's tripod mount for now.
thanks

Ultra telephoto photography is a lot of fun.
