A few months ago I purchased a mirrorless camera. I recently noticed some small circular markings on my images when using smaller apertures. I realise that this is probably dust on the sensor and that it’s more likely to happen now that I have a mirrorless camera compared to when using my previous DSLR. Although I know how to clean sensors, I used to send my camera for cleaning at Fixation every now and then. Can you recommend some cleaning products I could keep on hand in case I am on holiday when the problem occurs? Jeffrey Porrett Cleaning your own sensor is something we wouldn’t recommend you attempt to do without a professional showing you a safe way to do so. However, as you already know the process we would suggest looking into Visible Dust products. They make everything to clean sensors, from cleaning fluids and different-sized swabs to cleaning strips. One tip we can give is to use a very light touch when using swabs. Many mirrorless cameras have in-body stabilisation which could make the sensor move around as you clean. Be careful with this, as it’s not a cheap fix if it goes wrong!
