    looking for any advice from your knowledgeable guys

    i have noticed only very recently that my images seem to have developed spots or smudges on them (i have included a few images as examples), I have checked the lenses and they all seem clean and the images I have included were taken with different lenses on my NEX C3 body so I am assuming that somehow dirt has got onto the sensor even though when I look at it very closely I can't actually see anything there, not dust anyway, so is the cleaning something I would be able to do myself

    I would get a Delkin sensor loupe, and look through it as it is magnifiied, and lit. Next step is to buy a Sensor Swab kit for the sensor size you have and some Eclipse lens cleaner and watch this video

    Try the blower first - sometimes that's all it takes.

    The spots don't show up nearly so bad if at all at larger aperture settings. (Not that it would be acceptable to let that dictate your settings.)

    Bad news is, new spots will keep turning up. Good news is, it's usually pretty easy to digitally remove them from the image.

    Agree...it's not uncommon to get a spot of dust...I use one of those large "Rocket" shaped squeeze bulb blowers.
    And the tip I learned works fine...simply stop down to the smallest aperture and aim at a clear bright wall or section of clear sky and they show right up...blow them off...recheck, etc...done.

    +1 for the blower first. It gets rid off most of little dust.

    Yup.

    The camera also has a self cleaning mode. It won't get stuck on stuff off, but it will help with the everyday.

    +1 blower first, the camera facing down. if not sufficient, sensor swab size 2 with 3 drops of eclipse.
    That's what I do regularly. No issue, safe and effective.

    I have the same problem. My stuff is really stuck on good though. The blower did nothing. I have the eclipse cleaner and swabs now that came in the mail on Saturday, but it's still sitting on my table. I'm too scared to do it yet.... ;)

    Naaahh you should not. I clean my sensors regularly as I use quite exclusively primes and change lenses often. Keep calm, avoid dust around you, put 2-3 drops on swab, not more, and proceed as shown in the video. You'll be fine.

    don't know about those ones. always use sensor swabs. I know they are expensive but at least there is no surprise, they just do the job.
    Interested having your feedback...

    I read somewhere that Sensorswabs are produced in a sterile environment and free of any outside contamination. The other swabs may or may not have the same degree of qc. I'll stick with what works.

    went for the wet clean, i kind of had the impression the smudges wouldn't blow away so went straight for the wet
