Not very much difference from one image to the next. On Auto, my K5 did F5.6 1/40 ISO 3200 at 170mm zoom distance on the first attached photo #4869 and F5.6 1/25 ISO 3200 at 2400mm on the second #4855. Interesting that the one slightly longer shot of one of the speakers #4854 was better and its specs are F5.6 1/60 ISO 3200 at 113mm. Hmmmmmm. At least the next graduation this upcoming weekend is all outdoors so I don't have to worry about the pixels on screen; just have to find a good position with the sun at my back hopefully. Or I'll just have to walk around until I find a good spot to stand and try not to be too annoying
Thanks all for your input. If you think of anything else, let me know. I always appreciate getting your feedback to my questions.
