A mid-range zoom trusted for everyday use thanks to a balance of image clarity and handling. Design choices prioritise portability and straightforward control for long shooting days.
Reliable low-light and subject separation – with constant f/2.8 aperture
Constant f/2.8 aperture keeps light transmission consistent throughout the 28–70mm range, while a wide maximum aperture controls depth of field. Internal focusing supports maintaining focus while zooming without changing external length.
Easier handheld shooting in lower light and smoother control over background blur, useful for event and portrait work. Steady exposure simplifies workflow when moving between focal lengths.
Comfortable all-day use – with lightweight, compact body
A compact construction reduces bulk and weight compared with larger zooms, making the optic more manageable on a single camera setup. Mechanical choices focus on keeping balance and handling comfortable for extended carries.
Less fatigue on long shoots, walks and travel, so more opportunities to capture spontaneous moments. Fits well in smaller camera bags for quick trips.
Practical controls and durable finish – with focus mode switch and specialised coatings
A focus mode switch provides immediate, tactile switching between autofocus and manual modes for faster on-the-fly adjustments. Nano Porous Coating is applied to optical surfaces for improved handling of contaminants on the front element.
Quicker transitions between manual and AF let photographers adapt to changing subjects without fumbling menus. The coating and robust build add confidence for regular outdoor use.
