Camera Problems (4pics)

And now Сaturday has come again.

Greetings my friends.

It so happened that today my cat Busik turned out to be the central character again.
Yesterday I sat and dealt with an incomprehensible bug that appeared on the camera and took test shots.
What happened to the camera? By the way, I use a Nikon D5300 camera with a lens Tamron 18-400mm F/3.5-6.3 Di II VC HLD.
У меня имеются еще и другие объективы.
A couple of days ago I installed a lens Sigma 18-35 1:1.8 DC d72. After pressing the shutter button, the inscription "Error. Press the shutter release button again" and the camera only responds to this button. The aperture and shutter speed settings do not work.
I need to deal with this problem. After cleaning the contacts on the lens and camera, the error disappeared. Did I win? That's what I thought too. But today the error returned.

By the way, this is the original frame before processing.

In fact, this error does not always manifest itself. She appears and disappears again. I need to do more in-depth research on a similar problem.
Actually, at the end of 2021, I was thinking about replacing my camera. I was planning to purchase a Sony full-frame mirrorless camera or a Nikon full-frame mirrorless camera. I was inclined to the second option, although I liked the first one more. But at the moment, these plans had to be shelved. Life has changed a lot since February 2022.

This is my main universal lens that I use when traveling and walking. The remote control from the set-top box and TV is also visible. Oh, my iPhone is in the frame!

Does anyone recognize the movie? This is the American comedy "New in Town", 2019.
