Collector Notes:

This lens is a hidden gem for long-lens enthusiasts. While it’s soft wide open and prone to chromatic aberration at shorter focal lengths, it sharpens up nicely around 300–400mm when stopped down. The push-pull zoom is intuitive once mastered, though it may exhibit lens creep. A great choice for photographers who enjoy manual control and want to explore the 400mm range without breaking the bank.
