What are these white specks?

Could these white spots be "dead pixels"? My Olympus cameras have a function in the menu to correct for dead pixels. Check your camera manual for dead pixels and run the function to see if that helps.

Possibly, but only if they do not move between shots and are not perfectly round.
Dead pixels would be there in all shots, in the same place. He says other shots are fine.

Just got a D750 w 24-120 lens. Photos of the yard were great, but this photo of the sun showed white specks. I changed to a different lens, and still some specks. Any ideas?
Internal flare... uncorrected reflections of the bright light bouncing around from element to element or from front element to filter and back through.
Don’t use filters for astrophotography, to minimize such reflections. Lens flare from point sources is normal.

PS - no filter on the lenses
those could possibly be very minute bubbles in either the glass or bonding agents in the lens construction

ElNikkor,
I am sure you know that pointing the camera at the sun for prolonged periods can damage or even burn holes in your shutter and is tough on the eyes. Now about the white spots. For a long time, it has been known that viewing the sky in broad daylight from the bottom of a deep well. one can see stars. I offer no solutions but just a possibility that the white spots are indeed stars. Since your lens seems normal in other situations I submit this as a possible solution. Know any astronomy people??

Irish sun. Plenty of white spots if you zoom in. I think they call it rain. 2005 vacation.

What you photographed are the souls of innocents trapped in the primordial ether.
(Or maybe it's solidified, particulate bio-matter from that time when you sneezed on your lens.)

It could be an aberration in the lenses. I have an older lens that when you look at it in certain light conditions it appears to have bubbles on the surface. When I shoot in specific settings I will get the dots you got I called the manufacturer and their response was is that it passed quality and they could do nothing to correct it other than to make an offer on another lens
That was my thought air bubbles.

I think the same as someone already mentioned. There is foreign matter, i.e. dust either inside or on the surface of the lens. The extremely bright light is bouncing around in the lens, illuminating this dust. There is no answer short of taking the lens apart and cleaning the elements. I've done that on old manual focus lenses. I wouldn't begin to attempt it on something more complicated, and I probably wouldn't do it again on one of my older lenses. Too tricky, and my coordination isn't what it was when I was younger. I'd probably strip the heads of the little screws.
