JohnR Loc: The Gates of Hell
 
Over the years I've had half a dozen or so Nikon APSC cameras with various lenses finishing with my present D5500 with 18-55mm kit lens and 18-300mm (a more useful lens) and in all this time I've NEVER had a problem with dirt/dust on the sensors ! Now every time I change lenses on my Sony A7M2 I have to remove the lens and clean the sensor. This also happened on a previous A7R and an Olympus OM-D E-M5 Mk II. Wonder what lesson we can learn from this ??

It is frequently said, unsubstantiated, that Sony cameras are notorious dust collectors.
Second your D5500 has a shutter protecting the sensor when you change lenses,thus less likely to get dust on a protected sensor.

I always try to squeeze bulb blow off my camera and lens before re attachment.
Mostly always works (mostly)

That's why I have a 24-240mm for the Sony, an 18-300mm for my Nikon and a 12-200mm for my Olympus

I have an 18-200 that lives on my camera.

Several observations:

1, Nikon is a more mature camera manufacturer. Their equipment, especially pro-grade, are more resistant to dust and moisture, both bodies and lenses. Sony, now playing with the big-boys, is starting to realize what it takes to be a top-tier camera manufacturer.

2, The mirrorless digital sensors, mostly until recent models, were just exposed to the world when the lens was removed, not hidden behind a mirror or shutter.

3, The sensor cleaning 'shake' option of many DSLRs executes automatically at shutdown, start-up and / or both. My Sony a7II does not have this auto-function.

4, If you change lenses with the camera 'on', the sensor is more likely to attract dust. This applies to all digital cameras.

Static charge on the sensor when active.
Dust attractor.

If you can clean it well then it's not much of a problem. I found it's quite difficult to clean a sensor very well.

Your #1 is total bunk, LOL

I have used the best from Nikon, Canon, Sony and I get no more dust on my sensors with Sony than any other brand.

A few observations and recommendations from an ole pro at this. I also pass on these tips to my hundreds of photo students I have taught over the years in my Photojournalism, and Digital Photography courses at a state university.

ALWAYS also blow out the rear of your lenses (while holding the lens rear facing towards the ground) before mounting them. A lot of dust and stuff can hang out there, just waiting for you to mount that lens and power on your camera, attracting that dust right from the back of your lens to the sensor.

ALWAYS blow out your camera with the lens opening facing towards the ground, so any dust or debris falls out and NOT back into your camera and sensor.

ALWAYS blow out your lens caps and camera body caps also, as dust hides inside them too, just waiting to migrate to your sensor.

ALWAYS change lenses with the camera lens mount facing towards the ground and after blowing out the rear of the lens, quickly mount the lens, while shielding the lens and camera from any blowing wind, using your body or any structure.

ALWAYS change lenses with your camera turned off, as when your camera is turned on, your sensor is charged and can attract dust like a magnet.

ALWAYS clean off your lenses and cameras before storing them away ,and when you take them out of storage before use as they can pick up dust from inside camera bags and cases.

The shorter flange distance with mirrorless cameras means that image sensor is much closer to the mount opening , and as such is more exposed to any floating dust.

Shutter close or shutter barrier features in cameras just add another surface to collect dust and transmit it to your sensor when retracted or engaged. I dont bother.

I use my gear in all indoor and outdoor shoots, in dusty, sandy, dirty, including desert and beach environments around the world. And I change lenses in the field all the time, even if need be in windy conditions, yet I really dont have a dirt or dust problem with the sensors of my Sony cameras. I often can go six months and even a year before I need to do a minor sensor cleaning with my Sony A1, A7RIV, A7SIII.

My methods work for me, they can work for you too.

Cheers and best to you all.

I have two Camera bodies and two zoom lenses.
Rarely do I ever remove a lens from the camera body.

Perhaps most of us cannot have multiple bodies nor desire to carry 2 bodies just to avoid changing lenses.
In fact last I looked that is the whole concept of the ILC is the ability to change lenses as things change

My Z9 is a dust collecting hog. My D850 not so much.
Yes, the Z9 has a sensor shade that drops down that helps.
I try to not swap lenses as much as possible mounting the Z9 with my 28-300 leaving my D850 for mixing if need be.
Ant it appears that Nikon now charges like $58 for a cleaning where it used to be $40.

Hello JohnR.

It's good to see that you have the same equipment as myself. To be honest the only lens I take out with me these days is my 18 - 300. What a brilliant lens that just about covers all my needs. Over the years I have also bought a Nikon 10 - 20 and a used Nikon 80 - 400 which will only work on my D90. Auto focus is very fast on this lens. I take mostly wildlife, and birds on our garden feeders.

Kind regards,

George - Shifnal, England.
