I am confused...zoomed out shots outside are not crisp

I noticed when I took these series of shots that when I stepped back, the cybersync was not as crisp but the one I shot closer up was. I had my shutter speed at 350 for the blurrier one and the crisp one is 1/60th. Anyone know why this is? I can't figure it out. Indoors it is crisp when further away though.

The top two pictures are the ones where I was closer, the one to right is the 100% crop - f4.0, 63mm, 1/60th, ISO 100, handheld, SR on

The bottom two pictures are when I was further away but still zoomed in the same, the one beneath it is the 100% crop - f4.0, 63mm, 1/350, ISO 560, handheld, SR on

Lens performance will vary based on focal length, focus distance, and aperture.

Typically, zoom lenses are worse on the ends of their focal length (usually the telephoto end is the worst), and all lenses are worse wide open, get better as you stop down the aperture until f/8~f/11, then they get gradually worse.

Also, handheld shots will always vary in sharpness. Some shots you may shake or rotate the camera slightly more, sometimes SR won't compensate as well, especially as the shake profile changes in time and it works on recent history.

Try to use more controlled conditions, such as a tripod.

What lens and focal lengths did you use?

Looks like it may have focused on the mesh behind it.

Every lens has a certain resolution. Once you're far enough from an object, you'll reach the lens's limit, and patterns adjacent to each other (i.e. letters) will become indistinguishable. This holds for all lenses, even the good ones. It's why you can't just take sports photos with an 18mm and crop them

That's the whole thing. I took the picture indoors and it was fine. The second set of pictures was 1/350 shutter speed and the focus was correct on the one when I was further away. I took many many shots and only uploaded these to show the example. The same issue happened repeatedly. -- Lens used was the Tamron 28-75mm, the zoom was 63mm --

I took portraits a week ago and I noticed a little blur too, my shutter speed wasn't that slow and I used flash and that helped but it was strange how the further away shots weren't all crisp when viewed at 100% crop. It seems it happens outdoors...

Post more examples...? It sounds silly, but are you not just cropping tighter with the 2nd shot, and hence there is less detail? There doesn't appear to be any more "blur" but merely a focal length change and more cropping, as evident by the increased depth of field. If you leave exif data intact, that would help as well.
