Thank you so much for the really valuable information...very much appreciated!
On the power off/on, I guess I was being a little too impatient when pressing the shutter. On the auto ISO, I'll definitely give it a try, as that's a pretty important one for me. I have found that the ISO button and joystick pretty easy to reach while looking at the EVF, so maybe there's no reason to reassign the top left dial.
With only a little time spent with the X-S10 so far, I have found the AF and image quality outstanding, as you noted. Even with the challenges of learning a new system, it's been fun getting to know my new toy!
Again, thank you for responding to my inquiry. Pentax Forums is a valuable source of information for Pentax users, and it's nice to know Fuji X Forum can provide similar advice and support.
Welcome rickc, I too was new to Fuji when I got my X-S10 and 16-80mm last December. It is a great camera and lens combo.
Point 1. To wake up the camera just half press the shutter button but keep it pressed for a second or too and it will wake up. When half pressed you will feel the IBIS doing its thing , thats OK, just keep it pressed till it wakes up.
Point 2. Set the X-S10 to M mode on the mode dial and you will have aperure on the front dial and shutter speed on the rear dial. Then set the iso to Auto, Press the iso button on the top plate and use the joy stick to scroll down to the auto iso settings. The user manual does explain the auto iso settings quite well (the pdf that is). Note you can also re-assign the top left dial to exposure compensation if you like that as well. I have been using these settings just lately to photograph butterflies at high shutter speeds.
I came from using Canon and Nikon cameras and find the image quality is outstanding and hope you continue to enjoy the camera.
Best wishes DaveC.
