Nokishita has spotted a new mirror lens from Kento listed as the Kenko 400mm f/8 IIS. Mirror lens are a lot of fun and generally come with a T-mount so you can adapt them to any system, but this one is designed for mirrorless like the new Tokina 400mm f/8 that is currently on sale for a great price on Amazon. Mirror lenses are great for getting a lot of sharp reach in a small size, but the bokeh can be offensive sometimes.
Mirror lens designs are quite simple and hard to mess up so just about any mirror lens will do if you’re just getting into them. The Tokina that I just bought does have something new and interesting to me though… It works as a 1:2.5 macro lens. No news about if the Kenko does the same, but it very well might. Below is the translated Nokishita text.
Pentax ” K-3 Mark III 20-40mm Lens Kit (Black / Silver)” and Kenko “Mirror Lens 400mm F8 IIS (Nikon F / Nikon Z / Canon EF / Canon EF-M / Sony E / Pentax K / Fujifilm X”・ Microforcers) ”has been added to some domestic retailers.
