Default 28-135 Lens is loose

Not sure if thats the proper way to describe it, but if its on my camera and i point it straight down, it will zoom out. it also has a slight bit of play, and dust on the inside of the glass. Its never been dropped, and im not sure how it happened. Been this way for a while and it started shortly after i got it. Has anyone else had this problem with that lens? My friend that told me about the lens in the first place said his did the same thing... got loose over time. Is this one lens Canon made that they didnt put a lot of effort into the quality or? Other then that, its a great lens. I just wanna know if thats normal, and how where would i go to get it fixed/about how much to have it fixed...

It's normal, but annoying. Search google for lens creep for a variety of "fixes"

Pretty normal for this lens. I have one that is the same way, but I will not part with it since optically it is a sharp copy.

Hmm interesting, thought Canon would be better then that... ok, how can i clean the inside of the glass... i have no freaking clue how dust got inside, but it did... so is there any way to clean that, or am i pretty well screwed on that as well lol?

Also, i agree its a great lens optically, it's a huge improvement from my 18-55 kit. Im just wondering what lens i should get next... thinkin about a macro or a telephoto.

Dust does not have any effect on the picture quality (unless it is bloocking up the lens) and is quite normal with many zooms. The 28-135mm seems to collect quite alot. I do not have the link, but removing the front element and blowing out the dust is a pretty easy procedure. Maybe somebody on here can provide an instructional link or you can try googling it.

Same here shutterwolf. My 28-135 is bad to creep out when pointed down but I knew by all the reviews before I bought it. Dust was also another known factor.

Even so this lens is one I'll keep around. I think it came as a kit lens on maybe a 7D but compared to the kits I've seen, this was one of the better lens.

Here's a link to a DIY fix for zoom creep on the 28-135.

The zoom creep, as everyone said, is very normal. I had mine for about a year, I would often pull it out of my bag with the barrel fully extended. However, this doesn't affect IQ at all, the only downside to this creep is the annoyance from shooting slightly angled. To resolve this, I just held on the zoom ring, no tape or any tricks to prevent it.

Dust is annoying but very negligible. The more action the barrel sees, the more dust it will suck into the element. Again, this doesn't affect IQ until it really builds up. You can always send it in to Canon to have it serviced.
