I've never tried setting the focal length in a custom mode as LEE suggested but this seems a great idea.
On a couple of my S-series cameras you simply set up your camera how you want it, let's say you put it in Tv (Shutter speed) = 1/500 and iso = AUTO then zoom to the focal length of your choice.
Finally, when you have it all tuned how you like, go into the Menu and find the "Save Settings" option. What this actually does is save it to your Custom option on the Mode dial.
Turn camera off, set Mode to C (Custom) and power on. You should hear it zoom slightly as it zooms to your saved settings.
Now you only need remember to leave your camera in Mode C and it will power on how you most like it.......like my old Olympus XA2 perhaps.
This saves me the hassle of, for some unexplained reason, my camera always being set how I really didn't want it at that precise moment.
Example - "Shit! I didn't realise I only had it set to iso 80"
Example - "Shit! 1/25th of a second!!! "
Example - "Shit! I didn't have it set to RAW" (Yes, it even saves the file type to your Custom mode)
As I mentioned it's currently set to take 1/500th of a second cycling photos in RAW (and I let the camera choose the iso... grainy is better than blurry).
If I were going to a sunny BBQ and was shooting portraits of friends I'd most likely set the focal length a bit longer, so it zoomed to,say, 85mm and iso 100 at start up.
