I just got a k30 a few days ago.. now im a total newbie with these cameras so i couldn't figure out if it was me or the camera but in video mode if i set the exposure to P is was perfect but if i put it on manual, no matter with the aperture fully open the image with the same light was alot darker.. i didn't investigate more yet.

I am new to the world of dslr photography, I bought a pentax k30 with 18-135mm lens a couple of days ago and thought it'd be nice to join a pentax forum to seek help and advice of things related as im a newbie..
hope there are people out there with knowledge and the will to share it.

and Im currently living in london.
