Depth of field table
Distances are measured from the sensor plane. Each cell shows the near and far limit of acceptable sharpness in metres (∞ = to infinity). Circle of confusion = sensor diagonal / 1500.

FAQ
What is the depth of field of the Tamron 28-75mm F2.8 Di III VXD G2 at f/2.8 and 3 m?
At 50mm, f/2.8 and focus at 3 m, acceptable sharpness runs from 2.74 to 3.32 m — about 58 cm in total.
What is the hyperfocal distance of the Tamron 28-75mm F2.8 Di III VXD G2?
At 50mm and f/8 on a Full Frame sensor the hyperfocal distance is about 10.9 m. Focus there and everything from 5.44 m to infinity is sharp.
How do I get more background blur with the Tamron 28-75mm F2.8 Di III VXD G2?
Open the aperture to f/2.8, move closer to your subject and increase the distance between subject and background, and zoom in to the long end. You can check the result in the calculator above.
