Dust on my sensor? Please advice

Hi

I went outside to do some pruning and found this beautiful bug shell. I decided to have some fun and check the capabilities of my 60mm doing some macro. To my surprise I found those dark spots in the photographs when I look at them in my computer screen. I had not noticed those black spots before, but I am afraid that the sensor of my Xpro-1 needs some cleaning. See attached images JPG OOC (I could not upload the RAW file)

Would you say that those black spots on the frame (center and other areas) is dust on the sensor? If so, any recommendations on what to do?

I will appreciate any advice. As you can see, those black spots ruin the pictures!

I would take a picture of a white piece of paper and see if it is still present. If it is, maybe put another lens on and do the same thing just to verify that it is the sensor.

Here is a pretty good article on cleaning sensors. I have never done it myself so YMMV.

Looks like dust but that's not a big deal.

Sensor dust is just a part of owning any interchangeable lens digital camera. They all get dust on the sensor sooner or later.

It may just blow off with bulb type blower or you may have to wet clean the sensor.

Sensor wet cleaning is actually very easy to do and there are everything from Internet articles to YouTube videos that show how to do it.

By the way, you and that 60mm lens did a good job on the photos.

That's sensor dust. I never worry about it all that much unless it becomes visible (stopping down to small apertures makes it more visible).

I have a very casual relationship with dust. When it needs removing, I blow it off with canned gas.

Apparently this is a VERY BAD THING to do but I'm just a little rebel by nature, so I do it anyway.

Turn on sensor cleaning in your menus, it will cut down the number of times you need to clean the sensor.

Yes, stopped down. Take two photos, slightly shifting the frame. If there are spots and they do not move (in relation to the frame), they are likely on the sensor, with a smaller probability they are on the lens.

Unless he is focusing on the inside of the lens, he's not going to see spots on the glass.

How do I focus inside the lens? Sorry, I just don't know how to do that.

Bingo!

You can disregard the dust on the lens theory.

Great Photo btw.

The spots appear to be dust or oil spots visible at the high aperture you used.  Having owned a D3, D3x, and a D600, I have become very familiar with sensor cleaning.

First try a blower of sorts.  Canned propellant air is usually not a good idea for first experiences.  If that doesn't work you have a few choices if you wish to go further yourself or you could spend some $$$ at a local camera dealer and have them do it.

If you try it yourself it seems to be a scary task at first but with a little experience it becomes second nature.  Though I use products from the following company they are not the only ones who supply products for dry and wet cleaning:

Copper Hill

Visible Dust also has some good products to clean sensors.  A few months back I got a real dark eyelash-piece of dust on my X-T1 sensor and no matter what I used it wouldn't come off.  Turned out it was a piece of debris that somehow got dislodged from inside the camera and situated itself between the sensor glass and the sensor.  Fuji repair fixed it but my issue is a rare occurrence.

Give the "blower" a try first then explore your options.  As some posters have said, dust and dirt are par for the course on interchangeable lens cameras.

Good Luck,

Bob
