I have some dust in my lens and came across this web site.

Anyone have any experience with opening up the lens and cleaning it successfully? What do I need to be aware of other than what is on the web site above?

My personal view is get a professional to clean the lens, and if you are doing this heed the warning about voiding the warranty, good luck ;)

Been there, done that, and gave up. ;)

I opened my Tamron 90mm f/2.8 macro "just for fun" when it stopped working (lens wasnt anymore under warranty and totally unusable anyways, now its my paper weight).

After taking the bayonet mount off, I couldnt get further simply because I would have destroyed everything in the lens.

If your lens has dust and it wont show up on images, do not open it. If its visible in images get a professional to take care of it. Good luck!

Good advise. Sounds like more of a risk than it's worth.

nah,

DIY is the way to go!

Take it to bits, take pictures as you strip it!

Clean it and assemble.

Not a good idea given how fragile all the ribbon cables can be, and they're not so easy to replace given that they are usually soldered on.

I agree, potential problem.

Many Canon lenses are VERY easy to clean dust out from behind the front element. I have done it a few times on these lenses:

EF-S 15-85
EF-S 17-55
EF 24-105
EF 28-135

(some others are also similar) (24-70 f/4 IS, 24-70 f/2.8 II)

You didnt mention (or did I miss it?) what lens you are refering to and to what extent of opening the lens are you talking about? Where is the dust?

I have opened several Canon lenses - 15-85,17-55,24-105,50 1.8 - and have had no issues. Ofcourse my opening was limited to removing the front element (seems that is where dust likes to collect) and cleaning things up. The 50 1.8 I disassembled in an attempt to fix it (not because of dust) but gave up on it after I saw just how complex a simple lens like that is (lens still functions as it did before I took it apart).

If you are mechanically sound,I personally see no reason not to do your own cleaning. And,Im all about saving money and learning. Take your time,watch how EXACTLY it came apart to ensure it goes beck together EXACTLY the way it came apart. My next project is to open my 24-105 deeper to diagnose a scratching noise when turning the focus ring - watched a youtube video a bazillion times,I know I can do it.


I used to think I was indecisive,but now I'm not too sure.
