What are these black spots? Nikon D610

juno_first · 27 May 2018 at 21:57

Been noticing some spots for a while in blue sky shots but they seem to be getting worse & virtually the entire image is now covered in them. Does the sensor need cleaning? I thought the D610 fixed oil leaking onto the sensor.

Lightning 270518
They're more prevalent after adjusting the gamma to suit this shot.

Crop 2

Here is the fixed Shot. It took ages to spot remove these in Lightroom esp as I have an old PC.
Did I miss a spot haha.

Dust (dirt) on the sensor.

Ah thought it was dust thanks. Had it 4yrs & keep switching between 35/50mm lenses as hate zooms.
I'll Google how easy it is clean or take it be done properly.

Easy to clean. Lockup the mirror, try a rocket blower first, if that doesn’t work use a wet swab.

yes, dirt on sensor.

Bugger. My brand new a7iii is doing this but only with the big zoom. Still going to be the sensor and not the zoom?

Never ever ever had this problem with previous cameras. And I have only changed the lens twice inside with this camera to the big zoom. Thought they auto cleaned themselves nowadays?

Sensor dust is a pain in the ass, I get it on my A7Riii and I've never taken the lens off since I bought it

Rocket blower, or just use the dust removal tool in LR/C1

Don’t know why the Sony sensor is so prone to it. I didn’t care where is used to swap my Olympus lens and never ever had one spec of dust which showed up on a picture in several years and never ever cleaned the sensor.

Oly have by far the best dust removal system. Panasonic’s isn’t great.

I’d check you can actually remove the dust because it’s not unheard of to have dust beneath the sensor glass and would need a return.

Hope not

I guess traditional sensors are behind a mirror box and the shutter is always shut when you change lens, Sony (and all mirrorless) are exposed at all times even though they have a shutter curtain.

I am not sure why they can't do the same thing wand have the curtain down as default.

Like I said though was never an issue with the Olympus. The Sony sensor seems to be a dust attraction system.

Smaller area = less chances?

The Sony is like 4 x the size, so 4 x as likely?

Maybe but two mft cameras over 5 years and not one spec of dust. Brand new sony less than 24 hrs old and I have 4 dust spots. shrugs.

The Olympus has much better sensor cleaning and has special anti-static coatings. I also never have issues with my Olympus.

With regards to the Sony, unfortunately mirrorless cameras are much more prone to dust problems (hence Olympus invested a lot on anti-dust technology). tryn to minimize lens changes in dusty environments by using zooms, or just be prepared to clean the sensor a lot

I've used the rocket blower loads etc. & theres still dust, before biting the bullet & getting a cleaning kit...
Being very careful, could a hoover pipe on suck be placed a few inches from the sensor?

No….just get a sensor cleaning kit.

You mean the ones which you actually swipe something onto the sensor? Seen lots of horror stories where that has gone wrong and there seems to be kits which are Sony specific vs other cameras which suggests the sensor is different on the Sony and needs different chemicals. Can you recommend one.

You use swabs and PEC pads as normal but you need this

The blue one is the old formula which supposedly can damage the coating on Sony sensors.

Crikey, my 610 maybe 4yrs old with 8000 actuations but the risk of wrecking the sensor is rather scary & would be expensive to replace. I think I'll take it a repair shop as the mirror is also dirty, maybe the time I fell over in the mud lol.
I like Nikon & the Sigma art 35mm is awesome.
