Most Pentax cameras, in my experience, tend to under expose. This is done intentionally because usually an underexposure can be fixed in post processing but an over exposure that blows out the highlights cannot be fixed. Personally I think they are too conservative in this matter especially with modern software tools but that's another story.

Anyway, the solution is to add exposure compensation to the camera. I never had a k-m but there should be a +/- button somewhere. Press that and dial in maybe +2/3 stop check the exposure and adjust until you like the results. If the is no +/- button it might be in a menu somewhere.

On my k-5 I usually have 2/3 or 1 stop dialed in to get the exposure correct.

It is simply underexposed. You can use the bright setting for the digital filter thing or just over expose it. The +/- button only allow to adjust in any mode other then M obviously. But it is indeed a +/- button that does it as i own a km.

I have a Km camera and a K5. On the Km,

On the Km I always shoot with at least +0.5 exposure using the +/- button as it tends to generally underexpose. I think its a behavior inherent in the Km. With the K5, I usually do not need to do that.

If you are new to the whole dslr thing, the exposure compensation button is just behind the on/off button.

About your lens question, here on the forums there is a lens database of both Pentax and 3rd Party lenses (Such as your Sigma)

for instance here is the listing for that particular lens: Sigma 70-300mm F4-5.6 DG Macro Lens Reviews - Sigma Lenses - Pentax Lens Review Database

The link to the front page of the Lens Reviews is at the top of every page under 'Lenses' or through this hotlink Pentax Lenses - Pentax Lens Reviews & Lens Database

I would also say your revised image has a bit too much contrast and/or saturation ..the colors look harsh as a result.

It is a learning process though

IF you want the most leverage in editing your image, I'd recommend setting the camera to a RAW format (such as DNG extension) and using a program that converts RAW to JPG. You will be able to adjust exposure, detail, and colors much more than using typical JPG format.

I am going to try the settings you recommended me !!!
