The clarity function is an algorithm that is able to determine areas where local contrast enhancement would improve the image.

In other words, it should improve perceived sharpness.

Pentax Q2 - Rumour with picture

Indeed the product highlights do not make the Q-S1 any different from the Q-7.

However the list confirms the sensor size is the same and that the body has SR.

Nonetheless the Q-S1 could have an improved sensor and image processing engine. Maybe the diffraction correction feature has been implemented in this body.

Cheers,

Help with K-01 problem: Dies every time I try to take a pic!

I have experienced the same problem. Wouldn't a problem with the battery be out-ruled by the fact that the problem does not occur while shooting video?

On another thread someone reported the same problem was solved after some repair related to the shutter.

K-01 is shutting itself down.

But the batteries weren't discharged. Since they were fully charged just before the camera locked up, after only a couple of shutter actuations.

As I wrote, it seems the camera employs some sort of electrical security measure and shuts the battery down, via an internal switch. The switch seems to be reset after a few seconds in the charger.

The problem with my K-01 seems to be shutter related. I noticed uneven exposures, as if the shutter curtain was delayed over a part of the image. Doing exposure bracketing made this behavior more obvious. If I recall correctly someone else's K-01 had the shutter mechanism replaced to correct this same problem (camera lock ups).

Firmware v1.05 changes?

Unlike the majority of the photo industry, Ricoh has a history of providing firmware updates to older camera models, notably to their GR digital line (and these are compact cameras with non-interchangeable lenses).

Is the K01 Fussy about Batteries?
Posted By slocant

Thank you for your thoughts on the matter.

I normally don't leave the charger plugged in. But I have done so recently. Although I'm not sure that's when the problem arised.

Nevertheless I'll check the state of the charger.

Also, I normally have:
  1. A battery in the camera;

  2. A fully charged one in the bag; and

  3. A fully charged one at home.


And I cycle those three batteries in that same order. When camera's battery is depleted, I use the one in the bag, the one at home goes into the bag and I charge the depleted one as soon as possible (and the it stays at home).

Maybe that isn't the best way to do it?

Any thoughts?

Cheers,

Maybe my problems with the K-01 are related to what has been discussed here.

What is the voltage output of your batteris when fully charged?

My K-01 has been shutting down unexpectedly when I trip the shutter.
It doesn't happen when filming or in playback mode.
It has happened with three Pentax batteries. One came with the camera (Amazon) and the other two I bought from B&H.
After the camera shuts down, the battery's voltage is 1.7v or 3.5v (can't recall the exact values).

However, after a few seconds in the charger, the battery's voltage output is reset. Maybe some sort of switch is in action here.

But then I measured the battery's output after being charged and it was 8.34v. Is this normal? The batteries are labled 7.2v.

I see the AC adapter for the K-01 outputs 8.3v (I don't have it) and the camera itself is labeled 8.3v. The battery charger outputs 8.3v or 8.4v.

Does anyone have a clue on what may be going on here?

Did anyone have this problem solved?

I've also downgraded from firmware 1.03 to 1.02 and back, to no avail.

Focus Peaking Tips

When I set my K-01 to manual focus mode and press the OK button to zoom in for focusing, the camera opens the lens up to maximum aperture so that manual focusing with focus peaking is done at the widest aperture.

The camera also opens the lens up to the widest aperture while autofocusing.
