Sound of K20D vs. K10D

Ever notice how different the shutters in these two cameras sound? I was quite surprised, having thought that the mirror and other noise producing hardware was pretty much the same between the two.

My theory is that they have upgraded mirror and shutter in K20D to enable Pentax to go higher pps in the future. With the 15 Mp they could not get the info from the sensor into the camera quicker than 3 pps though. I am sure next camera from Pentax will at least have a less resolution, higher speed shooting. That is not anything I prioritise though, so I would prefer the continue to work on excellent picture quality, maybe even higher resoution but then in ful fram sensor probably. New tech mirror and shutter is not a bad thing of course, and I am only speculating now. But they sound very different :-)

If I may be a S.A. in a jovial way, if one wants to shoot motion pictures, wouldn't a 1080p HD video camera be better? But yes, 15-30 FPS for 1/2 sec. could be very useful for capturing 'perfect' 15MP action shots.

Yeah, I guess that's how I'd describe the difference in the sounds, like the K20 is quicker.

G Money:

I distinctly remember reading, while intensely researching the K20, that the K20 has a "more robust" shutter sound than the K10. I think I can retrieve the review if this is important enough to anyone.

Also, if my memory serves me correctly, the expected shutter life (actuations) for the K20 is longer than that of the K10. I also think I can retrieve that information if it is necessary. If so, this surely accounts for the sound difference.

So does that mean the shutter is louder on the K20D?

That is hilarious!!!


I own the K20 and have not heard the K10 yet. All I have to go on is the reviewer's choice of words "more robust." Here is some online assistance for us:


Show Spelled Pronunciation[roh-buhst, roh-buhst] Pronunciation Key - Show IPA Pronunciation
–adjective 1. strong and healthy; hardy; vigorous: a robust young man; a robust faith; a robust mind.
2. strongly or stoutly built: his robust frame.
3. suited to or requiring bodily strength or endurance: robust exercise.
4. rough, rude, or boisterous: robust drinkers and dancers.
5. rich and full-bodied: the robust flavor of freshly brewed coffee.



While the use of the word does leave some ambiguity for interpretation, I believe the reviewer, who claimed to have heard and compared both shutter sounds, meant to say that (among other things) the decibel level reached in a K20 actuation is higher than that reached in a K10 actuation. However, I am not willing to put my month's salary on this.

I didn't notice much of a difference holding them side by side, although I was listening more for a sound reduction...
