Nikon Plena lens to appeal to cinematographers
Some features are leaking on the internet about the previously mentioned Nikon Plena and the lens apparently is now said not to include Nikon’s defocus image control.
Even if the lens doesn’t feature ‘DC’, the Plena’s optical design mitigates polishing rings (aka ‘onion rings’). There’s also a lack of vignetting that typically results in truncated blur disks or “cat’s eyes.”
Some effort has also gone into mitigating slight overcorrection of SA usually seen as bright rings at the edges of the blur disks, which is usually achieved via an apodization element, however, the bright rings remain in some of the darker disks.
All of the above indicates to me that the lens is aimed at discerning users and cinematographers in particular.
With this and several other recent releases lately, it excites me to say we are beginning to see Nikon re-emerge as an optical tour de force.
