Thanks everybody for usable hints.

My expectation that green button on K-3 should work better compared withPentax ist*DL but now I understand that maybe this camera should not be usedwith dummy green buton.

I purchased my first Pentax ist*DL DSL back 2004 and taking pictureswith "dummy green button" could not be compared with anysmartphone/iPhone on the market that time (let me try to find those images as wellso I can post it). Differences in image quality Pentax ist*DL DSLR vs phonecamera were enormous. The only problem with Pentax ist*DL DSL wasshooting in low light settings so I was looking forward solving the noise and blurrinesswith K-3.

Now I tried some of your advice using tripod. I don't like to use flash (built in) as it makes nonrealisticimages not capturing natural light in the room. Maybe I need to play with thata little bit more. I corrected exposure to 0, using tripod and used "Av" aswell as "Dummy Green". Lets also compare it with iPhone X (I will also tryto find some images from Pentax ist*DL DSL model 2004 vs phonecam shoots that time):

Comments on image quality? Compared with iPhone? I need to try with RAW format, any hints on simple to use software for this format?

Very bad experience with K-3 using with Sigma 17-70mm F2.8-4 Contemporary DC Macro OS HSM Lens
and Pentax SMC 40mm f/2.8 XS. Most of my photos taken cloudy days or taken inhouse are so bad than even Iphone is performing better. Images taken in living room in auto mode (green) jump to ISO 3200 and images has terrible noise. I upgraded camera with latest firmware without any better result. Maybe I am lacking knowledge to handle this very demanding camera compared with Pentax ist*DL DSL which performed even better related to noise/image and colour quality. Any advice or hint?
