The Leica DC Vario-Elmarit 25-600mm lens can boast of its full F2.8 range. No matter how far your subject is or how fast it moves, this lens won't let it escape. And the continuous F2.8 capability enhances low-light shooting throughout the zoom range.
Additionally, Panasonic's Nano Surface Coating technology can pride itself on the extremely low reflection rate applied to the Lumix FZ300 for exceptional optical performance with stunning clarity, reducing flare and ghosting.
