Some of my pictures have looked blurry or hazy lately when I thought I was in a a very clear and crisp setting with no haze or sunlight. I have never considered cleaning my lenses proactively, and I generally just rid the lenses/mirror/sensor of specks once I notice them. Is it common to proactively clean your lenses and equipment, even if you don't notice them being dirty just to ensure clarity, or do you avoid messing with them to be safe? I'd just like to know how others deal with the cleanliness issue. Honestly, I'm kinda scared of my camera because of the delicate nature of the sensor, so I don't go in there unless I have a speck I need to rid my pictures of. Thanks.
