After testing the OM System 50-200mm F2.8 PRO last year, I was itching for a fast telephoto zoom lens, but was unwilling to fork out USD3500-3700 for that lens. Therefore, when I saw the Olympus Four Thirds DSLR lens 50-200mm F2.8-3.5 in the marketplace going for about USD250, I just could not resist this bargain. I have used the old Olympus 50-200mm F2.8-3.5 extensively on my Four Thirds DSLRs E-5 and E-520 back in the day, but have not tested it on Micro Four Thirds cameras. I thought it would be so fun to bring this combo out to shoot some tennis action. I caught the TennisMalaysia National Circuit Leg 1 back in January 2026, and I am sharing some thoughts about this lens on OM-1 as well as plenty of new images. I have also made a video to talk about this here (click).
