⚡ At a Glance
- • Image Quality: SLD glass elements ensure excellent aberration correction and retain sharpness
- • Best for: Photographers using compatible Sigma Global Vision lenses who need extra focal reach
- • Not ideal for: Users whose camera or lens combinations cannot autofocus at F8
2x magnification doubles the focal length while SLD glass corrects aberrations. Dust and splash-proof construction supports use in challenging environments.
Extra Reach for Distant Subjects - with 2x magnification
2x magnification doubles the effective focal length when attached to a compatible lens, extending reach without swapping lenses. Magnification is a simple optical multiplication of the native lens focal length.
Greater reach helps capture distant wildlife and sporting action without changing lenses, making fast reaction shots easier.
Cleaner Images at Long Range - thanks to SLD glass elements
SLD glass elements are included to correct chromatic and other aberrations introduced by the extra optics. Optical correction preserves edge-to-edge sharpness better than standard glass alone.
Improved aberration control keeps images sharper and reduces colour fringing when shooting at extended focal lengths.
Reliable Use Outdoors - with dust and splash-proof construction
Dust and splash-proof construction reduces the risk of ingress in damp or dusty conditions, helping protect internal optical groups and mechanical connections. Compact physical design keeps mechanical tolerances tight.
Weather resistance and small size make the converter straightforward to carry and dependable for field work.
