Tokina SZX 400mm f/8 Overview

This Tokina SZX 400mm f/8 Reflex MF Lens with 2x Extender Kit enables you to double your reach and produce an 800mm effective focal length. Compatible with Nikon Z-mount cameras, this bundle offers a compact alternative to standard telephoto lenses.

Tokina SZX 400mm f/8 Reflex MF Lens
The SZX 400mm f/8 Reflex MF Lens is a 400mm catadioptric optical design super telephoto lens with a fixed f/8 aperture, which offers a compact alternative to standard telephoto lenses. It's lightweight and compact design fits easily inside a pocket or small bag and is suitable for travel, wildlife, and outdoor photography.
  • Manual focus catadioptric optical design telephoto lens with fixed f/8 aperture, which is compatible with select camera focus peaking systems and in-body multi-axis advanced image stabilization systems.
  • Multi-layer anti-reflection coating for efficient light intake and reduced flare, plus high-reflectivity silvered coating and a protective antioxidant layer on the back side of mirrored surfaces for long performance life.
  • Minimum focusing distance of 45.3" and magnification 0.4x can capture small objects, while the 400mm focal length reduces the possibility of casting a shadow on the subject.
  • Catadioptric design and construction creates a smooth and unusual donut-shaped bokeh.
  • Wide focus ring provides smooth rotation range of 270°.
Tokina 2x Extender
Extending the effective focal length of the Tokina SZX 400mm f/8 Reflex MF Lens, the 2x Extender increases the lens's magnification by 2x for a narrower field of view. In effect, this extender doubles the effective focal length of the lens, turning your 400mm lens into an 800mm optic.

Tokina SZX 400mm f/8 Reviews

This Lens Will Burst Your Bokeh Bubble

By Holly
Rated 5 out of 5

For such an affordable price this lens is worth checking out if you love bokeh. It's manual focus with a fixed aperture and fixed focal length. As such, be aware you might shoot with a high ISO if in darker conditions so you might want a tripod so you can lower the ISO and also b/c there's no image stabilization. Handheld was fine for me but you can literally feel the camera wavering a bit (figured my in camera IS would come to the rescue in this case). It's very light. You'll want to use focus peaking to help identify focus and it seems the focus is linear versus a center spot. It comes in 500mm also which has the same effects so I almost wish I bought that one for more reach so keep that in mind. This is a fun lens to create bokeh overlays with. I give it two thumbs up!

sharp enough and surprisingly usable

I've felt the need for a longer lens every time I've visited the zoo. I can't justify the cost of a super-long Nikkor, but this Tokina is inexpensive enough that I could talk myself into the purchase. It's small and light enough that it won't get left at home. I'll take it to the zoo on every visit. It has its disadvantages over the Nikkors - manual focus only, not weather sealed, and fixed f/stop. But it's enough lens for my needs. It's sharper than many lenses I've owned over the years, though not Nikkor-Z-sharp. A little tweaking in post-processing and the images are just fine, even with reasonable cropping. It's fast enough with reasonable ISOs for the shooting conditions I use it for. With peaking turned on, focusing isn't bad at all; but I've got years of practice from before autofocus was a thing. I'm more than satisfied with this lens.

With the 2X extender attached, I assume this becomes an f/16 lens setup at 800mm?

Yes, using the Tokina SZX 400mm f/8 Reflex MF Lens with 2x Extender Kit for Micro Four Thirds on a micro 4/3rds camera is like a 1600mm lens.

Is this apse or full frame? Listing says both.
Asked by: Grant
Since it’s a T-mount lens, it will cover the full 35mm frame. But with the proper choice of adapter it will cover any of the (common) smaller sensors such as micro-4/3 and APS-C

As of the date/time of this reply, the final production version of the Tokina SZX 400mm f/8 Reflex MF Lens for Canon RF have not yet begun to ship. However, from the sample images listed on Tamron's website, the Tokina SZX 400mm f/8 Reflex MF Lens for Canon RF does appear to have good image quality performance.
