The Olympus M.Zuiko 100-400mm F5-6.3 IS offers an equivalent focal length range of 200-800mm, making it perfect for casual wildlife and motorsports photography. Relatively compact, lightweight and weather-sealed, the 100-400mm also offers powerful image stabilization, which works with the 5-axis in-body system used in current Olympus mirrorless interchangeable lens cameras.
We took the 100-400mm and an OM-D E-M1 Mark III to the Pacific Raceway here in Washington State recently, to see how it performs.














Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
