Canon’s latest telephoto zoom lens, the RF 75-300mm F4-5.6, enters the market not as a groundbreaking innovation but rather as a cautious refresh of a classic, budget-friendly design. In fact, its optical construction closely mirrors Canon’s EF 75-300mm F4-5.6 III, originally released in April 1999. More than two decades later, Canon has reintroduced this venerable lens for RF mount cameras, targeting beginner photographers and hobbyists who desire an affordable option for wildlife and sports photography without breaking the bank.

Sony Electronics recently announced the introduction of the FE 50-150mm F2 GM lens, model SEL50150GM, characterized primarily by its constant maximum aperture of F2 across a telephoto zoom range. This lens represents a unique addition to the current range of telephoto zoom lenses available for the Sony Alpha camera system, specifically due to its combination of focal lengths traditionally covered by prime lenses (50mm, 85mm, and 135mm) into a single zoom lens.
