Tokina — SZ-X 70-210mm f/4-5.6 manual focus telephoto zoom for vintage SLR mounts
The Tokina SZ-X 70-210mm f/4-5.6 was a budget manual focus telephoto zoom from Tokina's consumer SZ-X range, sold during the 1980s alongside the company's faster RMC and AT-X lines. It gave 35mm SLR owners an affordable step beyond a standard kit lens for portraits and distant subjects.
Built around a one-touch push-pull zoom-and-focus barrel, it carries a manual click-stop aperture ring and period multi-coating to help control flare. Maximum aperture drops from f/4 at 70mm to f/5.6 by 210mm, a common trade-off in consumer zooms built to stay light rather than fast.
Sharpness is workable through the mid-range but softens toward 210mm wide open, wanting a stop or two down for best results, and telephoto bokeh reads busy rather than smooth. Contrast holds up in daylight, though coatings of this era struggle against strong backlighting.
These lenses circulate cheaply across most manual mounts and often turn up bundled with period SLR kits. Buyers should work the push-pull ring to check for grease-related stiffness, confirm the aperture blades snap cleanly, and inspect rear elements for haze on long-stored copies.
