today I'm going to show you how to clean the sensor in a mirrorless camera and
also ways that you can reduce sensor dust
if you own a mirrorless camera and especially one of the sony A7 series full-frame
mirrorless cameras you'll be very familiar with sensor dust the way that
you can tell if you've got dust on your sensor if you can't see it when taking
the lens off is to hold the camera up to an evenly lit sky put your camera into
manual focus focus to the closest point and close your aperture down then hold
it up against a white wall or a flat white sky when you move your camera
around the spot stay in exactly the same place one of the ways to reduce the
amount of dust getting on your sensor is to put a bit of sticky tape on the
inside of your sensor cover cap what this will do is when you're in transit
or when the cameras in your bag you'll have this in there any bits of dust that
come away from the sensor will then stick to the tape the other two things
that I always carry around in my bag are one of these blowers and obviously
the other one for just cleaning the lenses is a lens cloth so with those
three things in my bag I can normally have a dust free sensor so what I'm
going to do is go through the process now and show you how I clean my sensor I
do have a bit of dust on my a 7r2 so I'm going to clean that one the first thing
to do is remove your lens and make sure the just isn't on the back of the lens
I'll also use the blower to clean the front of the lens off as well so that
will remove any bits of dust and then I'll just put the caps on both sides of
the lens and put it to one side next I'll get the blower and clean out the
sensor area which we've used the blower to clean out that sensor area in the
camera put the cap back on and then go into your last menu which is the tool
box and find cleaning mode then just click on enter you'll have to turn it
off and on again after doing this process once you've done that put the
lens back on the camera and take another photo of a white wall or an evenly lit
sky now if you still can't get those really stubborn bits of dust off your
sensor the next step is to use the sensor cleaning kit I have this one from
green clean and it's a two part cleaning system so you have wet
swab and a dry swab this will get rid of any really awkward bits of dust on your
sensor so with those stubborn bits of dust the first thing to do is turn your
camera over and turn it on go into your tool box menu and select cleaning mode
and then click enter it will shake the sensor about if you have ibis in your
camera then it says to turn the power off and back on again leave it with this
message on and leave the camera on and this will lock the sensor into place
with this wet and dry sensor cleaner you're gonna start off with the wet swab
it's all in there it's all ready to go so you literally rip it open and pull
the swab out so once you've got this out be very careful about touching the end
this is going to go onto your sensor and it's going to put the wet solution on
the face of the sensor so all you're gonna do is just drag it across the
sensor these are one use only and that wet swab will dry up after a while so
the next thing you want to do is get the dry swab out and all you're going to do
again is just drag it across the sensor
once you've done that then turn the camera off and then turn it back on
again keep it facedown so no dust falls in on the sensor and either put your
lens cap or a lens back on and that's about it if you have a blower and a lens
cloth and use the cleaning function in the camera normally you can get most of
the bits of dust off your sensor also putting the bit of sticky tape on the
inside of your sensor cap normally gets a lot of that dust and that dust will
stick to that sticky tape if you do have a really stubborn bit of dust on your
sensor you can either take it to a shop near you for cleaning or clean it
yourself if you do clean it yourself take your time don't panic and go
through the steps that I've told you then you should have a dust free sensor
