It’s back! We missed you.
Readers on our forum have noticed that the product page for the Canon EF-S 17-55mm f/2.8 IS is no longer linked from the Canon USA lens lineup page. The product page still exists on all of the other Canon sites I have checked around the globe.
We imagine it’s just a mistake on the Canon USA web site and we expect to see the link fixed soon. Although, a cheaper STM version of this lens would definitely be a welcomed addition to the lineup as pointed out in the forum.
