Hood Adapter HA850-01 589
Compatible with 70-200mm F2.8 EX DG OS HSM
Hood adapter extends the length of the lens hood and provides more effective shading when used with digital cameras with an APS-C size image sensor.
* When using the APS-C Hood Adapter HA850-01 with digital cameras with larger than APS-C size image sensor, vignetting will occur. Please remove the hood adapter if you are using these cameras.
