Image quality results from the EOS 7D Mark II and the Canon EOS-1Ds Mark III behind the Canon EF 35mm f/1.4L II USM Lens are now available on the site.
These new results allow direct comparison of the 35 L II with a large number of other lenses. One comparison of interest is the Canon 35 f/1.4L II compared to the Sigma 35mm f/1.4 Art Lens.
What is still the case: B&H has the Canon EF 35mm f/1.4L II USM Lens available for preorder (initial inventory sold out quickly).
Can't wait? The Canon Store has the 35 L II in stock and several are available on eBay.
