Sony’s new $1,400 35mm f/1.4 GM lens, lauded by seemingly all who have reviewed its performance, has a part leaking issue. The plate on the outside of the outer lens group on which the basic lens specifications are written can fall off.
Sony Hong Kong is offering to fix this issue for those who already have the lens in hand who happen to live in there. Owners can go to this site to check their serial number to see if they are likely to have the potential problem.
Sony HK is calling the outer ring the “ornament plate,” in its communications. On other brands’ lenses, this plate often has a functional role of helping retain the outer group of lens elements, but Sony has in the past used this ring purely as a superficial piece of design.
We know this because they had rings falling off of their FE 28-60 f/4-5.6 zoom lens, and it appeared to be a flat plate stuck on with a couple spots of glue. Other badge plate issues have cropped up on high-end Sony lenses, such as misfit silver lens information badges on the FE 600mm F/4 GM. Sony’s US service branch did not return queries by the user of that lens (in that case, this author).
Interestingly, Sony offices in other parts of the world have not followed suit with similar warnings. Readers in the rest of the world can follow this link for a $7.52 solution that won’t involve six weeks of shipping and delays.
