Hi welcome, I can not help with questions as I speak canon not Nikon
On my canon if it’s in auto and can’t find the focus point it will not take pic. Have you tried other setings

Welcome, I cant say if this would be your issue but I had a D50 with a Sigma 70-300 and the lens had a manual aperature ring on it. I had all sorts of problems with camera operation one day and found that the aperature ring on the lens had been rotated. The ring on the lens is not used and It had to be in the highest number FStop position (F22) in order for the lens and camera to operate properly together. If the tamron has the ring see if it has the same limitation

Hi, and welcome.

I only speak Fuji .... but could it be that at f22 the shot would be underexposed, so it's prompting you to pop up the flash?

I tend to use Aperture Priority, set the aperture I want for the depth of field I'm after, and let the camera choose the shutter speed and iso

Hi,thanks for all replies,seem to have possibly cured it (touches wood), did a reset then tried all lenses on A mode set at f5 ,shutter now releases, so was it set to do something it didn’t like or was I doing something wrong, probably me, so used to my old Minolta x700,s,once again thanks for tipt/help.
