Some very nice Pentax K-x ISO 200 shots. The last shot (of your feet) is perhaps the most technically interesting since it is a 1/4s handheld shot at 42.5mm FL. Conventional wisdom says you need a shutter speed of at least 1/FL(mm) * crop factor to avoid blurring. The crop factor for a Pentax APS-C camera is 1.5, so the formula suggests using 1/(42.5 x 1.5) = 1/60s. Now 1/4s is 4 stops below that.
1/60s -> 1/30s (1 stop) -> 1/15s (2 stops) -> 1/8s (3 stops) -> 1/4s (4 stops)
While the shot is not 100% sharp, it acceptable for the mood of the shot & shows the substantial benefit of the built-in
SR in Pentax DSLRs.
