I realized a comparison between two old Canon of 2002-2003

Here's another one you might like at ISO6400. Commonly the high ISO levels are used when I have people or wildlife. That's because of the motion. If there's a landscape...of course...I'll slow the shutter speed down as low as practical. Without a tripod, sometimes I'll set the camera on something flat or brace the camera against a tree etc.

But for these birds that are hopping around...I got to have high shutter speeds. I don't have to wait for sunny days or summer. I can take these all day long in the shadows and during rainy or cloudy weather. That's important for me because of where I live.

I might as well show you one more....at ISO4000.

those pictures are perfectly fine for casual shooting at high ISO. tonight i went out and shot some birds at ISO 3200 and with good results. the great advances in all cameras in the last 10 years is probably with higher ISO quality.

with most things i stay a generation or more behind and pick up the values available, and there certainly are a lot with photography. eventually i look forward to a mirrorless camera and have become fond of them since shooting bridge cameras for a few years. right now i am thinking about the FZ200 and FZ300 for those days of portable more casual shooting.

this was shot with my T3i at ISO 3200, noise is evident, but good enuf for me. i think the T7i may eliminate this noise?

your Tamron lens is probably superior to my Canon 55-250, but i intend to stay on the lower end lens in the near future.
