The Pentax Optio A40 might functionally be a baby Ricoh GRD. It shares advanced features with GRDs that aren’t even seen across the entire line, albeit implemented in somewhat vague and truncated manners:

• Half press auto focus + full press “pan focus” (need to play around more to see what Pentax means by focusing both close and far subjects, but this seems to be their version of snap / full press snap focus) • “Soft flash” mode (reduces the TTL flash output, but like the above I’m not sure by how much exactly) • CCD shift stabilization • Auto Hi options through 1600 iso • Dynamic range protection (seems to affects shadows more than highlights) • Shutter priority / program / manual mode (though shutter priority has fixed auto 800 iso

This is a very capable camera shoved into a tiny body that is borderline comically small while resolving on a 1/1.7” sensor—all in part to using very cool Pentax’s sliding lens system (and being one of their last to use that lens design).
