The optical design of the 85mm f/1.4 Zenitar dates back to a lens released in the 80s in limited quantities and available in K-Mount only, AFAIK. This lens has been available again brand new in a newly designed outer shell for some years now. I have one of the very first batches, brought by a friend when he was visiting Russia some years ago. I had to once dissemble it because a mount modification had gone bad so I know that the complete optics are being moved for focus as one single block, like an adapted enlarger lens.
I somehow had the feeling that it would perform nicely on the GFX sensor. I once had swaped its native F-mount to a self made MD-mount, so I just bought an appropriate adapter for that one.
The Zenitar has its share of spherical aberrations wide open and performance near infinity at f/1.4 is horrible. However, it shows absolutely no hard vignetting, has a very even light falloff and a very interesting rendering, especially at portrait distances, which I like a lot.
Some sample images from a recent walk in the neighborhood. All OOC JPGs this time. Because of the sill hard light around afternoon, all shot with a high quality polarizer. If you see a slight decentering of the vignetting, that's due to the image stabilizer.
Solid performance at f/2:
Detail at f/2.8:
Increase of detail from f/1.4 over f/2.8 to f/2.8:
Light falloff at infinity for f/1.4, f/2 and f/8:
Will it flare? Oh yes, it will: the 80s called, they want their multicoating back (full sun in the image will reduce contrast and increase flair even more, a lot more!)
Performance at f/8 again:
Thanks for watching! |

I have this lens in the N mount for Nikon, and I like it very much. Yes, corners at f1.4 leave something to be desired, but center performance is good even wide open and I very much like the rendering and bokeh. These on Sony A7R2 and R4

@kymarto these are very nice samples, indeed. I didn't do much close-up work with this lens yet, but your pictures motivate me to do so. Thanks for posting. |
