in the top corner (obviously) now for a stupid question, Is this mark in the top right or left when I look at the sensor??

Sony a7Riii mirrorless :sony:

I want it gone- it' so annoying more than anything - I have run the sensor clean program in camera- use a rocket blower and my soft brush to no avail and looking inside the camera with a very bright light it is not visible to me :mad: I have contacted LCE for a price on cleaning the sensor

any other suggestions welcomed - please forgive the TP page as an image lol

I'm 99% certain the image is inverted.

The mirror on an slr flips out of the way as the image is taken.

I agree- However: there isn't a Mirror in a MIRROLESS camera - the clue is in the name :)

Yes, that's the point. When the mirroe flips up, there is no mirroe in the light path. The mirror is for the viewfinder.

Ergo, at the moment of taking a picture there is no mirror, as per a mirrorless camera.

Perhaps it's a little early?
 
Here we go - using my nice shinny new Sigma 24mm f1.4 ART lens- shot @ f1.4 ( no dust bunny to be seen :)

With just one dust bunny in that spot I wouldn't worry about it. I don't like them near the middle of the sensor or in places where they're likely to fall on an edge...but there it is ok for the following

a) in any likely crop you are likely to remove it - I always take a little off the edges to remove any softness resulting from a poor lens
b) if you shoot landscape etc it's going to be in the sky - which makes it easier to clone/remove
c) if you shoot portrait etc you'll shoot so wide it won't be visible anyway

I agree with all you say Steve- I usually shoot Birds- Wildlife and to be honest as you say it can be cropped out or Cloned- I prefer not to have dirty equipment - but that's just me :)

Thank you for taking the time to comment

I'm glad it's sorted.

No big deal but I'm curious. Lee made sense but I got a terse response for saying the same thing.

Oh well, that's forums I guess.

Anyway, happy for you.
 
Are you sure that is not a spot on your computer screen.........?

What aperture was it taken at and have you got a bird picture or similar where it shows up? NB used to be received wisdom that to check for dust bunnies was f22 , plain surface and defocus.

PS nothing visible on your kestrel and shoveller ducks, surmising that they are full sized images.

An upside down image is nothing to do with mirrors or sensors; all camera lenses produce an inverted image (regardless of whether that image is projected onto a sensor or film). Ye cannae change the laws of physics, Jim (or Les). :)

Use a Sharpie (other marker pens are available) in the top left corner of the screen and see where it is in relation to the bunny...
 
AFAIK

A dust bunny at top left 'as seen in the image' is actually bottom right on the sensor....................the lens (the laws of optics/physics) apply i.e. the lens inverts in both planes, not just the vertical, so top left on image does not simply translate to bottom left on sensor!

It matters not whether OVF of dSLR or Mirrorless with it's EVF!

It's probably on the monitor... ;)
I've spent way too much time trying to clone monitor spots out of images...

Glad I am not the only one who thinks that......^^^^^ post #19 ;)

No, Jeff, all a pentaprism does on an SLR type camera is turn the image the right way round for the photographer to see. The inversion of the image is due to how the lens works, and this even applies to pinhole cameras. Try an internet search on the subject if you doubt this. (y)

The eye does the same, and the brain flips it....
 
After a relatively short time wearing flipping lenses, the brain sorts it out. During the acclimatisation, there may be problems!

They were there- I just cloned them out - now I don't have to as the sensor is now CLEAN :)

I do apologise for the response, I was getting a little frustrated with the whole issue to be frank- I hope you will accept my public apology Simon :)

Ah!

The Arctic Butterfly always got good reviews though I never got one and used alternate product on my dSLR's

But I wonder now on mirrorless, especially Olympus with its IBIS sensor, that that is more appropriate cleaning device?
