Cleaning a lense

[tidus10]

Hello Folks!

I dont really post in here much because im not a huge fan of my setup for tank shots, but I figured it was a good resource to ask this question..

I brought my lens with me to Jamaica, and through my travels, i broke my 70-200 lens and now my other lens is a 18-200 which im not a huge fan of.. but also its REALLY dirty from the travel..

It has fibers and dust INSIDE the lens body... Can i take it apart and clean it like anything else? Is there any draw backs to this?

others may chime in, but I wouldn't recommend taking the lens apart. My understanding of the common wisdom regarding this is, if it isn't affecting the image quality don't worry about it. If it's really bad and is affecting the image quality i'd send it to an authorized repair shop and let them clean it, but that's me.

Im seeing a LOT of bit in the images.. it breaks my heart I just ordered a sensor cleaning kit from the Amazons.. any suggestions on where to send it to?

B&H has a quality service department. Thought needs to go into this. It can be expensive.

Do you have another lens? First you need to make sure it's not just sensor dust. With another lens take an over exposed image of the sky or something white with stopped down to F22. That'll give you a good map of any sensor dust. Then take another the same way with the suspect lens. if the spots match, it's sensor dust. if they don't, some of the ones that don't match might be the lens. Personally I just send my stuff to Canon. However that's usually only if I break something or think it needs to be adjusting. I've never had the need to send a lens out for cleaning and I do my own sensors if the need arises.

Well, I can literally SEE the particles inside the lens.. If I look at the front of the lens I can see dust and fibers inside it.... I have checked out my sensor and it's fairly clean. I just wasn't sure if I could take the front lens off my lens and clean in there myself.

Seeing dust inside of the lens isn't always an issue. I've had stuff I could see in my lenses before and it never affected image quality at all. If the images you take have dust spots on them, and you're sure it's not sensor dust, then it's time to send it out. Maybe a Google search could show you how to open and clean it, but my lenses cost me a bundle. I personally wouldn't mess with it.

But are you sure it's not on the sensor?

if you can see it in the lens, then it's not the sensor. most lens dust will not affect picture quality. do not attempt to clean it yourself. needs to be done by a pro. I wouldn't worry about it unless it's rally bad, and if it is, there is something wrong with the lens. you should never have that much dust in the lens.

What am I looking at here? Looks like I'm looking down the lens at the sensor? Did you try images with two different lenses both stopped down of an overexposed sky or white background? Until you do that you don't know if it's the lens or the sensor.

No no this is from the sensors point of view
