Rebel T7i still shots suddenly blurry

[squeezy]

Hello,

I use my Rebel T7i with a Tamron 60mm f/2 macro lens for nail polish photography. While shooting, my shots suddenly got blurry and I haven’t been able to get it back to its crisp shots.The two images are shot at the same settings (ISO 800, f6.7, 1/500). I didn’t change the settings but I may have moved my light a bit. In any case, I’ve tried getting shots of different objects, a differently lit area in the room, changed settings, cleaned the lens…it’s still hazy! 

I don’t know what else to do to fix it.

Forgot to add the images

What is the minimum focus limit of the lens, you might be right at the limit.

The minimum is 9 inches. I did try adjusting the distance from different subjects and they’re all coming out with the haze.

I suggest you use the option to review the focus points:

I’ll try that! Thanks!
