I have been shooting with the pentax K-5 for a while now without any problems nor worries, until today i decided to tho the senor stain test. As it turns out my camera does have the stain on the sensor but, its so tiny it took me a while to find it. I began to wonder to myself how detrimental is this really to normal every day shooting because, you have to go to such extremes to actually see it. So i ask you are the stains really so bad that the ruin you ability to take normal every day photographs? I do understand that for the price you pay you expect a perfect problem free camera but, how often is anything is life perfect huh :ugh:? I'm a very novice photographer and i never really pixel peep to find problems in my photos. I'm happy as long as they are pleasing to the eye. So i ask you professional more seasoned photographers and novices alike, how much do the sensor stains affect you, and are you keeping or returning your camera?
