I've had my E-510 since mid April and it's always taken crystal clear photos. So I was naturally surprised and devastated when I went on vacation this weekend, took over 500 photos, and returned home to my computer to find that every single one looked slightly blurry--kind of like it had been zoomed in further than it should be, even at a low magnification. I had used all three of my lenses, so it wasn't a problem one particular lens, and all of them were clean. I have most of the settings on auto and use the portrait, mountain, and macro settings most often. I looked at my settings and they are as follows: Gradation: Normal Weird symbol thingy: HQ WB: auto ISO: auto Noise filter: standard Noise reduction: on Metering: the first option lighting bolt and plus/minus signs: 0.0 AF mode: s-AF+MF [---] : auto AE BKT: off WB BKT: R off, G off FL BKT: off Anti-shock: off Image stabilizer is on IS2. To my knowledge, these are the same as the settings when I originally bought the camera and the same as the ones I've used for the past two months. Does anyone have any idea why my pictures suddenly look fuzzy? Thanks in advance. I can also send samples if it would help.
