Dust is all around us, and when swapping out a lens on a digital single-lens reflex camera theres a chance that a camera s electro-statically charged image sensor will attract micro dust that can ruin photos. Since the main advantage of using an SLR camera is the ability to change lenses for better imaging effects , Olympus has developed a way for photographers to enjoy the freedom of using all the lenses of the Olympus E-System in the most challenging, dusty environments without compromising image quality.
this sounds real good but i will not switch. even tho i just sent my ist back to pentax to remove a spot i could not blow off or swipe off.. it came back, even after a pro cleaning, with 3 spots still on it.. i'll swab it soon to see if that helps.. i really like the istDs's images.. -- save one at a timewww.texasbostons.com
Oly's not much better, they sent my fixed lens c8080 back with a dust spot trapped in the lens chamber! My compressed air is just itching for a chance to nail it, unfortunately I cannot disassemble the camera shell too far and thus it is doomed to be sent back- again. Uuuugh....another reason to get a SLR. -- It is the mark of an educated mind to be able to entertain a thought without accepting it.
