Tokina has announced an updated version of its 400mm F8 mirror lens that tweaks the optical detain and adds a T-mount system that Tokina says improves the performance of the lens and enables the lens to be used with eight different camera mounts.
The Tokina 400mm F8 N II S mirror lens is a successor to the 400mm F8 N S mirror released back in July 2020. The updated lens is constructed of six elements in two groups—a departure from the six elements in five groups used in the original version. The lens has a minimum focusing distance of 115cm (45.3″), has a 67mm front filter thread and measures between 82–112mm, depending on whether you get the SLR or mirrorless mount versions, as the mirrorless versions have a longer adapter to account for the short flange distance of mirrorless cameras.
The 400mm F8 lens is fully manual and features an integrated T-mount that uses the standard male 42×0.75 thread; by using various adapters, which are place on the lens before being shipped out, the lens will work with Canon EF, Canon M, Fujifilm X, Micro Four Thirds, Nikon F, Nikon Z, Pentax K and Sony E-mount camera systems. Naturally, the T-mount means the lens can easily be adapted from one mount to another with a different mount adapter.
As is the case with all mirror lenses, this lens features the signature ‘donut’ bokeh, which is usually considered less aesthetically pleasing than the bokeh of conventional optics, but is the price paid for getting longer focal lengths in a relatively small body. Below are the only two sample photos Tokina has provided at this time:

The Tokina 400mm F8 N II S mirror lens Is currently listed on Tokina’s website for around $262, but it doesn’t appear as though it’s possible to actually place an order at this time. The first orders, when they go live, are expected to ship starting December 24, 2021.
