Internal Dust in a lens

I assume internal duct does not appear when a photo is taken, am i correct?

Does it have any affect at all on the workings of a lens?

And lastly, can it be removed easily?!

Thanks,

Re: Internal Dust in a lens

I think Internal dust will appear on a photo but your lens has to be at a specific apeture and focus for it to show up, as far as I'm aware the dust has no affect on the workings of the lens but I suppose it will depend on how clogged the lens would get, getting rid of dust would mean sending it away for service, can be a bit costly, I think generally poeple just put up with it and edit it out which is so much easier and cheaper

Ive got 2 wee small specks on the inside of my 18-70mm lens Steve but from what I've taken it hasn't affected the image from what i can see.

Re: Internal Dust in a lens

It will slightly increase the risk of flare, but if there are only a couple of small specks it shouldn't matter and it's probably not worth the cost of having it cleaned.

Re: Internal Dust in a lens

I had some dust inside the front element which was only visible on my shots at extreemly small apertures of f16 to f22.

At these small apertures dirt on the cmos sensor also were visible.

You can clean the sensor(if your really careful Steve) but as regards the dust inside the lens you will have to return it to the manufacturer.I gather in your case that will be Canon. Check to see if it is still under warranty. If it is then Canon will do the necessary under the terms of their warranty. My 17-85mm Canon lens suddenly showed light dust particles inside the front element after about 8months.These could have got in through the seals but I doubt it a more likely cause would be at the manufacturing stage!! You should first of all telephone Canon and they will give you the web address where you can lodge the fault and they will give you a case number in return and also a list of addresses to where you may send the lens for repair.
Obviously one in N.Ireland would be usefulI hope this helps Steve
Regards Brian
