OM System 150-600mm f/5-6.3 IS Review: Can’t Argue With a 1200mm Equivalent
An OM System 150-600mm f/5-6.3 has been sitting in the office for months and I haven't touched it since I tested the OM-1 Mark II. Finally, the cold weather had given way and I had no excuse to ignore it anymore. A trip to the Calgary Zoo would let me test out not only the wildlife capabilities of this lens but also the excellent macro versatility that the lens offers.
