Sensor cleaning
7 months ago

The sensor of my Sony A7R is always picking up little specks of dust, which I can't remove by using the camera "clean" control or a blower.  I could leave the specks there (there are 2 now and my camera is only a few days old--but I've been changing lenses to test them), but I suppose I am a little compulsive and the specks are very annoying.  Do you clean the sensors and what do you use?

I have a similar question. I have a small fingerprint smudge on my A7r sensor, lightly touched the sensor when changing a lens. I know there is a sensor glass layer in front of the actual sensor even though there is no low pass filter. I do not see the smudge in photos from what I can tell. Any input or suggestions?

dont think of them, when its starts to appear around F16 then clean it with wet method...Dust has static charge and it wont go away by just canned air sometimes...if you do a lot of macro, this can get annoying..this is why, I use LAEA4 adapter so it stays there since my lens are all A-mount..this is actually an advantage + PDAF capability while protecting your sensor..

Here's a good guide to cleaning methods: http://www.cleaningdigitalcameras.com/methods.html

I'm getting good results with the first method listed, Sensor Swab™ and Eclipse™, after using a Giottos Rocket, and Carson SensorMag LED Lighted Cleaning Loupe, all from Amazon.

Someone here mentioned canned air. Don't use that.

If a carefully controller bulb-blower isn't working, which surprises me for dust, then you can use a lens brush or get one of the sensor cleaning kits.  I've used lens pen (brush and carbon tip) to clean mine without problem, but I wouldn't go near it with a wet wash, personally.

Is the A7R particularly sensitive to dust problems?  I own and use  Nikon, Aps-C sensor cameras (5100, D300) and have never had dust problems..  Is it that the greater size of the sensor and the higher resolution amplifies the evidence of dust?

No dust issues here
In reply to M Dennis Fern, 7 months ago

I've changed lenses in the field, left the body with the sensor exposed in the trunk while mounting adapters on MF lenses, left the camera with the sensor exposed on a tripod while going to the car to get the other lens, no issues at all. This in stark contrast with my Nikon and Canon bodies with which I wouldn't have dared behaving thusly, being virtual dust magnets. I think a simpler box construction by Sony, with no obstructions or protrusions, is helping in this regard.

All I use is a rocket blower a few times during a session and so far I couldn't find signs of dust.

On my N7 I have used a simple and very cheap method several times.

use alcohol, the medical 96% type and cotton swabs.

no problem, the alcohol evaporates and my sensor is very clean again,

Olive oil. Simply the best.

Yep, I do that too when necessary.  Eclipse on a good cotton swab works well too for cleaning all kinds of things.  Just don't use too much liquid solvent.

Re: Sensor cleaning

While looking for advice on the Internet I ran across a sensor cleaning device which consists of a little square of a gel-type product at the end of a plastic rod.  I discovered it through a UTube video about cleaning camera sensors. It's featured on a site called photographylife.com, where it sells for about $44.  Amazon seems to have an identical product supplied under the Foga brand (a Chinese photo product supplier) for a fraction of that price.  The gel square is sticky, but supposedly doesn't leave a residue.  It comes with paper treated with something that is more sticky than the gel and removes the dust.  I've ordered one, but haven't decided whether to use it on my camera. I've never cleaned a sensor before and am a little intimidated. Anyone tried this product out yet?

Another vote for sensor swab and eclipse-- I've wet cleaned my A7r sensor several times, and I think owing to the absence of a mirror box/ short registration, it was far w easier than on my DSLRs

Living in an environment that combines both dust and high humidity I have to clean the sensor on my a55 fairly often. I use the cleaning kit put out by Delkin. This kit gives you a loop that lets you see just what you are dealing with, a small vacuum that does a good job on the loose stuff as well as swabs and a solution to do a wet cleaning if that is needed. I have used this set since my a100 days and have been pleased with the results.

Here is a still taken from a video shot with my NEX-5N (AVCHD 1080p50). What do those little black dots look like to y'all? My sensor (or at least the filter/glass in front of it) appears clean, as do both ends of the SEL-1855 lens that I used to shoot this.

It was actually pretty bright out when this was shot so the aperture was probably getting pretty near to the top end of the scale at the time of this still (around the F29 mark I think, at 55mm, I was shooting in shutter priority mode).

The below images were shot several days before the video above, and show up some stuff as well, but in different positions (at least to my eyes!). This leads me to believe that I could just be dealing with mucky stuff on the lenses (both of the below images were made with the Sigma 19mm) that I'm not seeing clearly when cleaning. And by cleaning, I mean that I have only ever taken a rocket blower to this camera and the aforementioned lenses.

Thanks in advance for any help or advice you guys can offer!
