FAQ
What is the depth of field of the Tamron 70-180mm F2.8 Di III VXD G2 at f/2.8 and 3 m?
At 100mm, f/2.8 and focus at 3 m, acceptable sharpness runs from 2.93 to 3.07 m — about 14 cm in total.
What is the hyperfocal distance of the Tamron 70-180mm F2.8 Di III VXD G2?
At 100mm and f/8 on a Full Frame sensor the hyperfocal distance is about 43.4 m. Focus there and everything from 21.7 m to infinity is sharp.
How do I get more background blur with the Tamron 70-180mm 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.
