What We Like
+Class-leading 4.1x zoom ratio maintains constant f/2.8 aperture throughout entire range for consistent exposure and low-light capability
+Effective built-in VC image stabilization (approximately 5 stops) especially valuable on APS-C crop cameras that often lack in-body stabilization
+Fast, quiet RXD autofocus with minimal focus breathing makes it excellent for both stills and video work
+Compact, lightweight design (540g for Nikon Z version) with excellent close focus capability (0.19m at 17mm) ideal for travel and everyday use
+Versatile 25.5-105mm equivalent focal length range covers wide-angle through short telephoto without lens changes
+Weather-resistant construction with fluorine-coated front element provides durability for outdoor shooting
Worth Knowing
AF tracking responsiveness may decrease during zooming in video mode on Nikon Z mount version (documented limitation)
Some distortion at extreme focal lengths, though automatically corrected in JPEGs and RAW converters
Longitudinal chromatic aberration present, particularly noticeable as cyan/magenta fringing beyond the plane of focus
No physical AF/MF or VC ON/OFF switches on Nikon Z version (only available on Canon RF mount)
