I ran some tests a year ago that showed me, personally, that my tripod images were either equal or better with SR on than with SR off. Same with a 2 second delay and SR. But with a 12 sec delay, off was better. I was headed out to the dog park yesterday afternoon (a grey and rainy day) and noticed a couple of our favorite birds sittin' on the "swim to" platform in Palmer Lake. Positioned the car to afford me a shot or two, using the half way up window to steady the camera and 18-250 with. Looking through the viewfinder at 250mm, I was shocked to see how unsteady my hands have become. Tried spot & center AF, MF, and not using the window as a brace, plus 250mm vs 100mm. Think it was between 1/60 and 1/160 of a second with SR on. Nothing was sharp enough for my tastes. Guess I'll have to start lugging to 60-250 brick around. A few months ago I got some nice sharp images at the dog park with the lowly 80-300 FA-J that looked better. than this 18-250. With less CA too. Best at 250mm, and best (cropped) at 100mm plus a crop of a 250mm shot. Mind you, these were shot at jpeg, 5 stars, 16 mp. http://tinyurl.com/8dt4ag5 Joseph McAllister [email protected] -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
