A55 - is it ghosting I'm seeing?

When light passes through a glass at an angle, like this,

there's a* ghost image due to internal reflection, shifted sideways a bit. I don't think it can be totally avoided. Canon's Pellix cameras used a very thin (fragile) membrane, I believe, to keep the ghost image as close to the main image as possible. Since the image is upside down on the sensor, the ghost will be below the main image when the mirror is tilted upwards.

In the digital age, there is some potential to subtract the ghost image - as long as the main image hasn't clipped, in which case it's not known how much to subtract.

Now, I wonder if what I'm seeing in these gallery images is ghosting?

They are zoomed in to 200% to make it clearer what I'm thinking of. I have to say the problem seems less pronounced than I had feared when I heard the first rumours about the A55/33.

* Naturally there are many ghost images, but all but the first one is too faint to matter.
