nikon d850 showing shutter blade on some pictures

[npb850]

I'm using a tamron sp 150 - 600 f5-6.3 G2. after shooting for half a day, it started to show. any ideas what is causing this and how to fix it. also the camera is new

Could it be the lens hood?

 

[npb850]

no, because I took it off and still was doing it for some pictures

Depends on HOW new. If return is an option that's probably the best policy.

Be sure all testing is done with a fully charged known good battery.

I prefer to test with an OEM lens just to eliminate any firmware gremlins.

Try a two button reset (which I doubt will do anything but it won't hurt anything either)

See if you can make it happen with the mirror locked up.

Best WAG based on pretty much zero information: sticky shutter requiring service center intervention or sticker mirror requiring service center intervention.

Almost all of my equipent is secondhand these days but I buy ony from a reputable dealer. Never privately.

I don't like the sound of what you are describing. I'd send the camera back.

Two decades ago, after some days shooting extensively in a safari by boat in Amazon rain forest my (then new) Nikon D100 started to have some odd behavior with its shutter. Sometimes timing differently from setup, sometimes did not working at all.

When returning home I sent it to Nikon Service and the diagnostic was it loose shutter lubricant (I had no idea shutter had lubricants). Apparently the hot climate was responsable for it.

They remade lubrication and I never had again any problems.

Perhaps your camera have similar problem.

It looks like the mirror gets jammed sometimes. It should be checked whether the mirror moves freely or if there are any obstacles to the movement.

I have seen same, when I was using third party lenses, like Granit 11n.

 

[capanikon]

take the lens off and do a 30-sec exposure, take a peek inside.

don't touch anything tho.

could also be the. mirror not fully retracting.

What you see is the up and down moving anti reflection shield in front of the AF sensor. It cannot be the mirror, because it is at the top of the mirror box (the image is upside down in the camera).

Thanks, but it isn't my problem any more.

My solution was dremel.

The Granit11n has a short hood on the bayonet end, that the mirror collided with. That hood had to be trimmed a bit.
