Canon CY3-2030 Rear Sleeve
Genuine Canon replacement rear sleeve assembly for the EF 24- 70 2.8 L USM lenses. Canon stopped supplying the lens mounts in various thicknesses and now supplies the rear sleeve assembly that way. This sleeve assembly can be damaged if the lens is impacted or crushed. Several sizes of this sleeve are available.  The most popular is 2.30mm and the next is 2.60mm. We stock the most common sizes and backorder the rest. Most backorders ship within 3 days after your order is placed.
More information concerning the rear sleeve measurements is listed in the Canon update bulletin here, ef2470 SM Correction
