Originally posted by BigMackCam Hence my thought that adding mass - say, via the tripod socket - may alter any resonance in a specific body that might be contributing. I've mentioned before, I think, that I play guitar (or used to - not so much in the last few years), and it's not uncommon for some guitars to have a "dead spot"... a note that, when played, sounds flat or "dead" compared to others, with no colour and/or sustain. Adding mass can fix this, or - at the very least - move the frequency where the dead spot occurs... I have no evidence that this would work with a camera and shutter shock, but I think it's worth testing.
No, you haven't told me you play guitar. So do I, and like you, not as much as I used to...
My guitars usually have large or pretty hefty necks, that improves sustain and I don't think I have any issues with dead notes because of that
Regarding mass - I was surprised that the DA 35 Limited seems to help the camera have no shutter shock, while the Sigma 30 1.4 Art, which is quite larger and heavier, does. The main thing that is different about the Limited lens is that it fits *very* tightly in the K-mount. Not sure if that has anything to do with this... another lens that doesn't seem to have any shutter shock is my K 55 f2 - and that one fits very tight in the camera mount as well. Probably coincidence... but still!
I think I'm leaning towards the K-3 now anyways - I miss having a pro style body (other than the K10D of course), and I think it has less shutter shock than the more entry level cameras, which is a bonus. Still, the screen and extra features of the K-70 have their appeal... I have time to think about these things, it will probably be a few weeks until I put my K-S1 in the market and pull the trigger on a new body. I have to sell some of my lenses first...
