K3 slow power ON ?

I've tried searching for an answer .... couldn't find it (even in my own posts!! )

Question: Is it "normal" that the K3 is slower to power ON vs. the K5 ??

Thanks!

Maybe if startup SR was enabled in the K-3 but not K-5...?

Define "slow". It takes mine approximately 2 seconds to power up.

Startup SR ??
Well, the SR is always ON, no matter which camera I use.

That would be about right: 2 seconds.
I was wondering because the K5 is faster to power ON.
Nothing to worry about then?
Thanks!

I meant DR - dust removal... oops.

You can set it to start-up, shut-down, both or neither.

I think he meant Startup Dust Removal. But on the K-3, like the K-5, the amount of time taken is negligible.

Yes of course, and I always have this ON as well ... makes hardly any difference in start up time, really.

One difference is that the K-3 has 2 card slots, and it scans the card at startup. Do you have 2 cards? Mine seems to startup faster with just 1.

I would try turning off all the Dust Removal settings and formatting (both) your SD card(s).

Regardless though, the K-5 has less startup delay:
600 ms vs 900 ms

K-5 has less shutter lag as well:
104 ms vs 138 ms

Imaging Resource measured the two cameras as follows:

Power up to first exposure
K-3: ~0.9s
K-5: ~0.6s

Shutter lag time (pre-focussed)
K-3: 0.96s
K-5: 0.92s

It would be nice if they had measured the startup time-to-ready, but that is hard to determine. Still though, I don't know that two many of us would be aware of the 0.3s difference unless we had the two cameras together at the same time and had a race. After all, how often do we have the use case of full-off to full-on in order to catch the shot. It takes me over a second to simply bring the camera to eye!

Next question:

Is it normal for my right leg to move faster than my left? This has perturbed me and is getting a little old. Every few steps, my right needs to stop in order for the left to catch up.

Just one 32GB card in slot 1.
Planning to use both with 32BG 95MB/s SDHC I (U3)
So, I haven't yet put two cards in that K3.

Pentax K-3 vs K-5 - Our Analysis
900 ms is close to one second ... but the start up time (guesstimated) for the K3 (mine) is 1.5 - 2.0 seconds.
Same with power down.
I can live with that. I'll turn the start up DR and see for myself what the difference is, if any.

Thanks for the info.

There is such a thing as "dominant leg" but has nothing to do with being left or right "handed" ... lots of further info on the Web for that!

I had a K30 that was very slow on almost everything. It took 2-3 sec even for turning off: the screen kept on after the power switch was turned to off; the light meter system also took 2-3'' to respond to quick light change.
It turned out the mainboard (processor) had issue.
I hope your K3 is not like this.

Doesn't seem to behave like your camera:
I was using only one SD card in slot 1 then I've just inserted the two Sandisk 32GB cards and .... guess what?
The power up seems (I think) faster ! ??
Power down stayed the same ... roughly 1.5 - 2.0 seconds.
Anyway, this is not a big deal and I will go out tomorrow and try to get some wildlife (after the snow storm and freezing rain) to see how this K3 performs related to "high" ISO, i.e.: 1600 and up, outside.
