Are ET-83 and ET-86 hood interchangeable (for 70-200 2.8 IS)?

They are not interchangeable.

The number in the model name refers to the diameter of the bayonet mount, ET-83 is 83mm, ET-86 is 3mm larger. The IS version probably takes in a slightly wider view ahead of the IS elements, so needed a new wider hood. Canon made them unique so that the older ET-83 wouldn't be used on the new lens by mistake.

Hey everyone,

A quick question: the ET-83 hood is supposed to be for the 70-200 2.8 non-IS, and the ET-86 hood is for the 70-200 2.8 IS. From what I remember the lenses are pretty similar (size-wise) - are the hoods interchangeable?
