Which in turn replaced two *ist-D bodies. Which replaced two MZ-S bodies. Since at least the MZ-S period, my practice has been to have one body with added vertical grip, one without. Bigger heavier lenses go on the body with the grip attached. With the K20D I noticed that the shutter sound on the two bodies was different, one much quieter than the other. While at GFM in 2009 I asked John Carlsson (sp?) about the difference, wondering if one was somehow defective. We went through a series of comparisons of the two bodies, with and without grips, with different lenses mounted, etc. Conclusion was that they both sounded the same as long as they both had a grip attached (or not) and as long as they had the same lens attached. But the variation in dampening effect produced by the different attachments was quite dramatic. I presume that I had not noticed the difference on earlier body pairs simply because the shutter was basically louder to start with, and therefore there was a smaller percentage change due to dampening factors.
I would not be at all surprised to hear that the same AF motor in two different bodies would sound quite different. stan -- 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.
