Sensor question

Good evening
im just picking your brains. I took my D750 to a camera shop to have it properly cleaned over the weekend.
When I picked it up they said there were marks on the sensor and that they had done the best they could, but it might be an idea to send away for a proper service. I've had my camera for about a year now and I really do take care of it so why has this happened? Is it inevitable that sensors get marks on them? I can't remember if he said scratches or not and I'm actually really worried now. Has anyone experienced this? How much is a service? Where do I send the camera? The camera is never left without a lens on it. Why? Help. I'm gutted.��

The first thing I'd do is learn how to clean the sensor myself. Don't be afraid..... it's exceedingly difficult to screw it up.

What do you mean by 'marks'? Is it dust, or did they actually manage to scratch the glass? Or maybe streaks from using the wrong fluid (you don't use Windex........)?

I've never heard of "marks" on the sensor and I'm not sure what they mean by that. That being the case, if it were me, I'd want to talk with the techs in the shop until I had a full and clear understanding of what they think the problem is. Then I'd probably seek a second opinion. What they are suggesting you do, by the way, is send your camera to a Nikon repair facility to have the sensor cleaned/repaired. But before you do that, I suggest you try and get more information on what it is they saw. "Marks on the sensor", in my opinion, is not really an answer. If that's all they'll give you, find another shop to clean yours sensor, or just do it yourself.

The more important question, I think, is if you're seeing any problems with your images?

Thank you Paul. I'm going to ring them tomorrow and ask them to be more specific. I'm shocked because I'm so careful with it. I'll definitely ring them tomirrow morning see what they have to say.

DON'T BE. It's very very very difficult to damage your camera.... unless you use a hammer drill and sandpaper.

It's as easy as cleaning your glasses. Or your computer screen. Or your windows. Or your smartphone screen.

The first red flag I see is, what kind of shop tries to "clean" a camera... and then hands it back to the customer and says send it to the manufacturer for a "proper" cleaning????? Why would they even accept your camera to begin with if they couldn't do a "proper cleaning" ????????? Cleaning a camera sensor is child's play for a shop that professes to do anything with a camera... Your camera shop may have actually damaged your camera's sensor in NOT knowing what they were doing...

You should take some shots with the camera with the lens pointed at a white card... and then blow the image up on your computer screen to see if there is any dust/marks...

They also sell a special loupe/magnifying glass that's used to examine the sensor...

Wet cleaning a sensor reeally is very easy... there are YouTube videos that walk you throw the entire process...

What I'm curious to know is if there was an actual problem you were seeing in your photos before you took the camera in to be cleaned or if you just thought it was time to have the sensor cleaned on general principle, took it to your local shop and were then told about these marks on the sensor... Because in all honesty I'm just a little dubious about this diagnosis. I think we can all understand that sinking feeling that comes from being told something is horribly wrong with our camera, but at this point I'm not convinced there is anything wrong with yours.

In fact, if you have a photo or two you could upload here to the forum that you took with your D750 a lot of us around here have software that would make any crud on the sensor stick out like the proverbial sore thumb. I'd be happy to take a look a picture or two and let you know what I found. I'm not qualified to diagnose any issues but I'd be happy to check for "dust bunnies", oil spots, etc. and let you know what I think.

Depends on the grit rating of the sandpaper. 240 is OK, 120 is bad.
