The new Share feature on lens vs lens is something I built for photographers that like to talk about lens comparisons in forums. Say you’d like to tell the user SIGMAMASTER that the Canon equivalent of the 70-300mm zoom blows the Sigma 70-300mm out of the water, come over to lensvslens.com and conduct a search. Then click the new Share button at the top of the screen to copy the URL to this search to your clipboard.
You can even narrow your search down by aperture or focal length:
Now compare the Sigma and Canon zooms at 300mm
