Built in level on K-5

I see that they have added a built in level to the K5. One of my pet peeves with my K10D is no matter how much I try to take a level photo, half of them come out crooked. I don't know why, they just do.

Is the level based on gravity or is it tied into the sensor's position somehow?

I think that it uses accelerometer technology just like the iPod touch/iPhone/iPad.

It bounces signals off the moon and triangulates with the Wailing Wall.
One of the fairly common faults on the K10 was the sensor being held ever so slightly off level.
OTOH, the level on the K7 is known to be slightly off as well.
Anyway, the level is gravity based, but whether the system is absolutely accurate will depend on the individual assembly of the camera.

Does it cover the full 4 axes, or only two, landscape and lateral?
(or is it a basic gyro-attitude meter like in cars/small aircraft?)

To be complete it would need to handle 8 in fact, for portrait position.
?

Or do we still have to keep our $5 clear resin hotshoe mount 3-bubble levels?

This is old news. Some early K10D had issues of the sensor being slightly misaligned.

It handles pitch and yaw in both horizontal and vertical orientation.
If your shoe mount level is actually accurate, keep it, you'll find it easier to use than switching the camera level on.
You can customize the raw button to activate the level, but then you lose the ability to use that button for a couple of things that I find more useful.

Those are now 100% obsolete Pentax K 5 Features worth noting I - Pentax News & Rumors - PentaxForums.com

Unless the electronic level can be calibrated by the user, I have my doubts about its performance.

Seems a hotshoe bubble level is only as good as the hotshoe-sensor alignment, which I doubt is any better than the sensor-viewfinder alignment, and it seems not handy for hand-held shots.

Both my bodies have the Pentax tilt, so reaching for the Elements leveling tool is second nature, now.

Excellent. Sounds like they did the job pretty well.

Relief! We might not need to buy one of these essential-gadgets-to-sustain-life after all...

Serious, I find the cheap resin block or button ones handy to glue to tripods and heads too. Mfgrs of those never seem to add enough or in the right places.

Any sign of lazer levels tech and sighting/distance gauge pointers in DSLRs yet?

Never thought about testing the levels in the K-7 or K-5 but I have a bubble level in my tripod head so I'll test them tomorrow, I also have a laser level i'll try to.

The one in my K-5 is perfect- dead accurate!

The other K-5 we got had a faulty one (off by 3 degrees to the left), and Pentax repair said that "it can be fixed via software, but we aren't able to do it yet". So we just sent back the body instead of getting it fixed.

rather difficult to know if your point of reference is off... i guess the horizon at the ocean is probably the only true test

The neat thing about an electronic level is that in theory it can be zeroed to agree with the sensor orientation. So any sensor-misalignment may be taken out of the equation. I hope this is what they do in the factory. Mine at least was bang on as far as I have seen (within 0.5 degrees anyway).

All you've got to do is put your camera on a level surface, check the reading, and then rotate it 180 degrees. If the readings aren't the same, then your level is inaccurate. Otherwise, they're kosher!
