The Wide Angle Zoom Adapter will enable most zoom lens / camera combinations with a standard 45 degree FOV to achieve a genuine 90 degree field of view.
The 0.5x Wide Angle Zoom Adapter from Resolve Optics is providing camera manufacturers with a lens accessory to deliver top quality video conferencing images.
In the world today - video conferencing is seen as a vital communications tool by a growing proportion of businesses.
However until the advent of Resolve Optics 287-000 series Wide Angle Zoom Adapter - image quality and performance have generally been a negative factor in the uptake of the technology.
To date all 'off the shelf' wide angle adapters have offered a compromise between field of view (FOV), distortion and resolution.
If the lens achieves the FOV and minimal distortion then the compromise will be the resolution and so on.
The result often is 'milky' out of focus images that get progressively worse the nearer you get to full zoom.
Aimed at the video conferencing and broadcast markets each production lens is individually collimated to maintain the full focus range of the prime lens.
Incorporating an M37 mounting thread the Wide Angle Zoom Adapter will enable most zoom lens / camera combinations with a standard 45 degree FOV to achieve a genuine 90 degree field of view.
The 287-000 series Wide Angle Zoom Adapter provides a true 0.5x field of view while maintaining minimal distortion and high resolution throughout the zoom range of your camera.
The compromise-free performance of the product was achieved by designing the adapter to work with the moving pupils of zoom lenses.
Its design combined with the use of specialised high index glasses carefully balances the provision of a low distortion wide angle view with the higher level of correction needed at the narrow angles of view.
The result is a high-quality lens that has an unprecedented full 'zoom through' capability resulting in high-contrast images regardless of zoom position whilst still maintaining both resolution and focus to the very edges of the image.
