    Hi All

    I bought an Olympus 45mm f1.8 today and when I got back I noticed a solitary small spec of dust inside the lens.

    It isn't very big at all, but I noticed it and I guess if I ever came to sell it, prospective buyers would notice it too.

    So, do I return it and wait for another to come into stock, or do I keep it and get on with using it?

    How common is this on new lenses?

    I am not sure how common this is, or if it will even make any difference in the images, but I would recommend returning if you think it will bug you. They seem to be coming back in stock pretty frequently.

    It's highly unlikely you'll ever see the speck in images, however, you're quite right that it could affect the resale value.

    Personally, I'd return it. When I buy something new, I expect it to be defect free.

    I've bought quite a few lenses and I've never seen dust in a new lens. Some lenses, e.g. the Canon 100-400 L which is a push-pull zoom, are referred to as dust pumps but they don't come with dust pre-installed at the factory.

    Unless someone tells me this could damage a lens, here's what I've done with great effect:

    Turn on a vacuum cleaner, set it to not the highest power, and put it up to the rear mount side. I've cleaned probably a half dozen lenses this way (of course, this is assuming you are not standing in a dusty environment at the time). I've gotten some pretty big dust chunks off the lenses this way.

    Only caveat is that while I've never had an issue, I've not done it with the 45/1.8, and I've no idea if the suction could knock anything loose. Start with a lower power setting, and only edge it up if the dust isn't moving.

    Good luck!

    (btw -- do a quick Google search. Here's one person using a vaccum on a compact camera: How to Clean Digital Camera Lens with a Vacuum Cleaner (with pictures) | wikiHow)

    I think I'll try returning it first, but thanks for the tip!

    Thanks everyone, hopefully they'll take it back without any drama, and that I can get another one this side of christmas.

    LOL, today I received a brand new Samsung NX200 and there was a hair inside the kit lens! Of course, it's not noticeable in any shots, but still it's disturbing. I guess quality control is pretty bad nowadays, and it applies to all manufacturers.

    QA is probably up to their waist right now in either radioactive sludge or flood waters :(

    I would return the lens. The return period is the only opportunity to correct the situation. Although it appears that demand for the 45mm f1.8 is high right now, another one will come along.

    I frequently get new lenses with dust inside, including several lenses which cost over $1000. I think it's normal (probably most lenses have a bit of dust if you look for it) and doesn't affect anything. I haven't had trouble selling them either. Most people know that a little dust doesn't affect performance.

    Most lenses have some imperfection - a slightly weaker corner, a bit of dust, etc etc. To me it isn't worth the trouble to look for perfect specimens.

    It's not worth worrying about, you're overreacting. It won't affect image quality, value, or any other tangible metric in any way. Live with it, and put it out of your mind.

    I had a strand of hair get into a Canon G9 and it showed up distinctly in sky photos; guess it must have been on the sensor. Had to send it in for service; about $135 for "depilatory"...
  12. The miniaturised lenses and sensors of a compact like a Canon G9 are more susceptible to problems caused by foreign objects inside or on the lens. For example, just see what happens when you get a raindrop on the front of the lens.

    Well, I returned it and they got me a replacement today, which looks fine.

    Seems to hunt a little less too!

    Thanks for your advice.
