Well, the first shots came back mostly nice. I have a few where the focus points I thought I hit weren't what I actually hit. I was aware of this issue with this camera, so I tried to be careful with it. I'm sure I'll get used to it.
I checked Keh for hoods and they have them for the GA645Zi, GS645 and GS645S; will any of these work on the GA645i? I also just ordered a 52mm lens cap with the attached string. That should be enough of a reminder for me (I hope).
I'm going to run some B&W film through it next.
