OK, it's late in the thread but I'll chime in. Like most of the previous posters I've experienced little problem with dust in my lenses, even zooms but of course zooms do generally displace more air unless they are of the internal mech versions. What I have experienced problems with is haze forming

I have never had problems with dust accumulating in lenses, and I have several old primes. I guess if I take the brightest LED flashlight I have and shine it in the lens I will see some dust. MOre evidence that this world is not perfect but nothing to get worried about. Lenses *do* wear out.

Bipin, Perhaps the best response so far. I am very careful and quick about changing lenses outside and generally won't do it if there is wind. I hear you on going for weather sealed lenses. It all comes down to cost. Hopefully I can slowly work my way into some better glass here. I've had good suc

Hello Zos I am a Pentaxian since some 36 years and shoot outdoors pretty frequently. But if you see my gear it will look as good as new. So are my laptops/tablets, the 35 year old brief case 4-in-one stereo system, the 3 or 4 binoculars, even my car. And yes you could sleep in my bathroom - it is s

I shoot outdoors almost exclusively. Back when I first started shooting for publications, some forty years ago, I didn't make much effort to take care of my equipment. I stored lenses in socks and wiped them with my t-shirt. Some of those lenses were ruined. Today, I'm cautious. I still shoot ou
