Re: What about immage stabilization and macro
Thanks Godfrey, I would think, if I can fill the frame with a reasonable sharp insect, it would be sharper with SR on. Pictures of insects in action cannot aleays be done with a tripod.Other means for stabilization are used by me, like elbows on the ground. At first sight I would think that a minor shake with small angle of view of macro will give the same blur on the sensor as a larger shake with a 400mm tele. Maybe the problem is that the Pentax system can not handle minor shake, due to shake sensor sensitivity or noise.

Re: What about immage stabilization and macro
exactly, maybe at the end it all boils down to viewing angle. Maybe focal length should be replaced by viewing angle at focus, gets us rid of correction factors for APS-C versus FF as well.

Re: What about immage stabilization and macro
The other big issue is that most SR systems only correct for angular movement (pointing the camera in various directions). At macro distances, translational movement (shifting the camera) is also significant. Canon has some recent IS macro lenses that are supposed to compensate for both types of movement.

The manuals do say to switch SR off if the cameras are tripod mounted. I think that covers most macro usage. Detailed macro work is almost always going to be on a tripod. 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 pentax...@mac.com -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

But with a 12 sec delay, off was better. Ah, now. Are you absolutely sure about that 2 sec delay mode? One thing I did find in the manuals (in the short periods of mental alertness) is that SR is turned off automatically whenever a self timer mode is selected Any of you dealing with ADD/ADHD know damn well that one cannot read a manual, let alone a book. Once your mind gets a chance, it flips the mental page to whatever you were just reminded of, and no ability to back up, unless something else you are doing in the near to far distant future reminds you of the manual, or book. Then you have to -a. find the bloody thing -b. start reading again from the front, 'cause you know you won't know where you left off -c. repeat. I'll have to check on that if and when I find the box with my manuals in it. I do remember the movers picking up the bookshelf then rolled it upside down so it's contents were spread around on the carpet. Either that or the stapled-on back of the bookcase fell off.. Only checking because it seems there has been a run of bad memory today. Dave Brooks! If I didn't go back and spell check, then read slowly what I've written for context, thanks to spell checkers changing words to what you think they might be, my posts would be mucho more unreadable than yours. Fingers get fatter, and don't go where you aim them much once you're decrepit. I have a hard time using my iPad if I allow my hand to hover waiting to tap the next whatever. Finger tremble, have their own mind about when to tap. Makes for frustrating backing up. Guess it won't be long before they're fitting me with a cheek-switch and eye tracking apparatus. Joseph McAllister pentax...@mac.com -- The Big Bang was silent, and invisible in it's beginning moments. Photons were one of the earliest particles to develop, but I don't think any were able to escape for a bit. If they could, there would have been a flash during expansion. No one would notice, of course, for another 4.2 billion years. Now we are trying to catch up by looking out, and back in time to that infinitesimally-small fraction of a millisecond in an attempt to see what caused that singularity to we call the Big Bang. This attempt will fail in any visual way, as the furthest galaxies and elements are now moving faster than light by recent theory, making the information sought beyond a theoretical event horizon. — update to the Pentaxian's thoughts on particle physics, so far. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
