Vista One are a modification of the standard Vista series lenses from Tokina Cinema. The fragile wavefront design of the Vista series allow for a pleasing flare that is taken to more extreme limits in the single coated Vista One series.
The front element receives a proprietary single coating technology applied to both the concave and convex surfaces of the front element. There are different coating types applied to each surface controlling the flare in ways that a simple polish and new coating would not provide if done by a 3rd party manufacturer.
The flare is heavily diffused with a strong blue color inclusion at wider apertures and secondary and tertiary flares coming in a green color that is normal for the Vista series. The green color is easily rendered to a white color in post allowing for a strong blue flare to remain after post production.
If higher kelvin light sources are used such as HMI then the flare turns white while still maintaining detail. The look of the flare is retained up to T5.6 which is relatively unique as most single or uncoated lenses will often lose their characteristic when stopped down just one or two stops.
Many single or uncoated lenses lose significant resolution in the white points of the image to the point of recording no information on the sensor in certain areas of flare. The Vista One retain resolution and detail even in the strongest flare making them more versatile and giving more freedom in creative choices.
The single coating allows for very little flare on-axis making the the Vista One behave much like standard Vista series lenses when the onset lighting is generally diffused without light sources in frame. The off-axis flare allows for maximum creative control with some diffusion making this series a versatile choice.
The Vista One series are a limited quantity manufacture lens series from Tokina Cinema and are distinguished from the Vista series by their grey color lens barrel and blue/white paint accents versus the white and green accents of the standard Vista lenses.
The Vista One are relatively new to the market however have gained use on several Amazon series and commercial use. Several feature films are in production with Vista One now and will continue to rack up credits as their availability increases.
