FAQ
What is the depth of field of the Olympus M.Zuiko 40-150mm F2.8 PRO at f/2.8 and 3 m?
At 85mm, f/2.8 and focus at 3 m, acceptable sharpness runs from 2.95 to 3.05 m — about 10 cm in total.
What is the hyperfocal distance of the Olympus M.Zuiko 40-150mm F2.8 PRO?
At 85mm and f/8 on a Micro Four Thirds sensor the hyperfocal distance is about 62.7 m. Focus there and everything from 31.3 m to infinity is sharp.
How do I get more background blur with the Olympus M.Zuiko 40-150mm F2.8 PRO?
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.
