Sony FE PZ 28-135mm F4 G OSS

Reviewers treat it as a production tool first. Zoom and focus transitions are smooth, breathing is well suppressed and the variable-speed servo zoom works for slow, even pushes. Centre sharpness is good across the range, with softer corners at the extremes wide open and noticeable uncorrected distortion at 28mm.

As a stills lens it is judged expensive and heavy for what it delivers. Its double linear motor AF is slower than current G and G Master zooms, and the f/4 aperture and 0.15x close-up magnification are unremarkable. Most testers recommend it only to people who need the power zoom and cine-style iris ring.

Videographers like the parfocal-like behaviour, the clickless iris ring and the ability to set zoom direction and speed, and many keep it on FX6, FX9 and FS7 bodies as a run-and-gun documentary lens. The OSS helps when shooting off the shoulder.

The complaints are about the weight, the 95mm filters, the price and focus-by-wire that some find vague for pulling focus by hand. Stills shooters who bought it as a walk-around lens often move to a 24-105 F4 G.
