Thanks Guy's for the info on the focusing and pardon for jumping in. Sounds real fine for me and what I want to use it for. Thank you.
Mark

I'm sure some lenses are sealed better than others...the 18-200 is really a consumer grade lens (albeit an expensive one) and is not weather sealed. Really regardless of who makes the lens, if you live or use your lenses regularly in humid conditions/moist environments you should take precautions (storing in a dry environment with silica gel packs or some other moisture absorber) against fungus. |

Someone once stated an obvious fact about zooms and that was when zooming they all suck in air,which is inevitable I guess. So that being the case they are all going to get nasties inside them from time to time. I have easily taken the front lens off of my !8-200mm a couple of times to clean specs off the inside. I have used it in some very dusty places though.

Not quite true. Some zoom internally. That is, the change in focal length is attributable to shifting groups within the barrel, not extending the barrel.

Dafiryde,
Theres nothing very technical about it.The front lens just unscrews in the same way as a filter.It's slightly stiffer though plus there is a very thin washer/sealer that the lens beds down onto, it will fall off without you noticing if you dont watch out. The only tricky bit is putting the lens back on, because it would be very very easy to put it on with a crossed thread, as it is an extremely fine thread. I backed the thread up until it clicked before screwing it on and it took me a few tries before it aligned up correctly.When it's properly lined up it tightens very smoothly and easily,so be very careful "gently does it" is the password. Do not use any force or you will be in deep do do. I am very gentle with my hands being a musician and artist. I hadn't had the lens very long when I noticed a speck on the inside of the lens, so it may have been there from new? the second time was earlier this year when cleaning my filter I found a speck inside the lens, perhaps it got there when I cleaned it the first time. I'm not sure that either of the specks would have shown up in a photo ( maybe in certain lighting) but I'm a fusspot. So I'm told by the other half.:-)

Sounds logical TCav, I think you will remember the post some while back, there was a lot of tooing and throwing about vacuums and bellows effects in zooms caused by their movements. I'm not sure about the outcome, if there was one.
