New K20D User - Green and P setting images seem dark / muddy

Thanks for all the great comments! It is clear that I mainly need to get used to some features of this camera; however, it is also apparent that perhaps with this lens the camera does not appear to be compensating entirely for lower light. And, that Panasonic is running circles around it when going from wide to telephoto on auto setting.

So .... this weekend, I will post some comparison images of both cameras taking pictures in the same setting and let you experts weigh in. I will also take some pictures of showing how the camera changes between wider angle and telephoto .... for example: I took a photo of the light blue ceiling here in my office fully zoomed out and it was nice and bright. Zoomed in to the same area on the ceiling produced a darker image. It seems to me in green mode the camera should have automatically brought that level up but it didn't. In any event, I appreciate all the feedback and I will post some comparison photos this weekend.

I guess that makes sense, though I wonder why the camera doesn't compensate for the higher F stop when zoomed in while in green mode. That dopey Panasonic looks exactly same as far as picture brightness throughout its entire 12x optical zoom range.

Also, just to test things, I put one of my older zoom lenses from my SLR Ricoh camera on this camera ... and no matter where I zoomed, the F stop stayed at 2.8 ... and the picture was MUCH brighter than the supplied kit lens that came with the K20D when zoomed all the way in.

Thanks for the very quick feedback! I added one other comment to my post before you responded, so I will repost my additional observation: I am noticing that as I use the included zoom lens, when I have it full wide, the captured picture seems as bright as the the screen ... and it is showing an F stop of F3.5. However, as I zoom in, it shows the F stop changing to F5.6, and the resulting captured image is dark ... just like I was encountering earlier today! So the zoom lens is controlling the F stop setting?? Why is that?

I am embarrassed to even post this question here because I'm sure that this is user error on my part, but if some more experienced photographers can take pity on me, I will be forever grateful!

My first 35mm camera was a Pentax back in the 1970s, and later I moved on to a Ricoh body that accepted my Pentax lenses. I had put off buying a digital SLR camera for years, but finally made the plunge last week and bought a K20D. Being that I am still getting used to the camera, I wanted to just take some images on as much of an automatic setting as I could, so I've been experimenting with the Green and P settings using the stock Pentax 18-55mm lens that came with the kit. The only problem I've noticed is the images indoors seem dark and almost muddy, compared with the images I've taken on other cheaper digital cameras on full auto setting.

I do some video work for Buffalo Wild Wings however they wanted me to take some still images at one of their restaurants this morning, so I thought it would be a good try out for the Pentax K20D. However, even after lighting a scene with a nice softbox, the images all seemed considerably darker, and muddier, than what I was seeing in the liveview LCD display, almost 2 stops darker. Nothing I did seemed to bring that image level back up: no matter what I was seeing on the LCD, the captured image was always dark and the colors muddy in the P or Green settings. The only setting that gave me a bright image was bulb, but that was inconsistent, sometimes bright, sometimes completely dark, and I was unfamiliar with that particular setting and didn't want to be reading the manual in front of the client. So I ended up giving up and taking the rest of my images with a Panasonic Lumix DMC-FZ8 which took wonderfully bright images that matched what I was seeing on the monitor.

So, I am sure I am doing something wrong ... what is it? Is there not a more or less "full auto" mode that I can use while getting used to this camera, and if green is that setting, like the manual says, why do my images look so dark? Any assistance you can provide for a dumb video guy trying to get back into quality photography again would be much appreciated!

A follow up: I am noticing that as I use the zoom lens, when I have it full wide, the picture seems bright as the the screen ... and it is showing an F stop of F3.5. However, as I zoom in, it shows the F stop changing to F5.6, and the resulting image is dark ... just like I was encountering earlier today! So the zoom lens is controlling the F stop setting?? Why is that?
