As we reported back in April during its development announcement, Tamron has now officially released its popular APS-C superzoom lens, the 18-300mm F3.5-6.3 Di III-A VC VXD , for Nikon Z and Canon RF mounts. Previously, it was only available for Sony E and Fujifilm X mounts. The new versions are now available for preorder at B&H Photo for $629, however the release dates are different: The Z mount version will start shipping on August 28 whereas the RF version will start later on September 26th.
Tamron 18-300mm F3.5-6.3 Di III-A VC VXD for Nikon Z and Canon RF Officially Announced
The optics and most features of the 18-300mm F3.5-6.3 Di stay the same across all mounts, however, the RF version is adding AF/MF and VC on/off switches right on the lens barrel which the other mount verisons lack. The other difference on the RF mount will be the slight difference in ff equivalent focal range: It is a 27-450mm for Nikon (1.5x crop) but a 29-480mm for Canon, thanks to 1.6x crop ratio of Canon's APS-C sensors.

The Sigma 16-300mm is curuously not available for Nikon Z mount so probably the only comparable APS-C lens for Z mount is the NIKKOR Z DX 18-140mm f3.5-6.3 VR but it is nowhere close to the versatility of the Tamron:
